不同激素处理对白桦幼树萌条及三萜合成的影响

探索一种可持续、稳定的获得白桦（Betula platyphylla Suk.）枝条的方法,拟通过促萌处理建立多枝条类型白桦材料。以一年生白桦幼苗为试材,采用3个截干高度：10、20、30 cm处理后,每个截干高度使用4种激素或化学药剂处理（20 mg·L^-1 2,4-D、20 mg·L^-1 KT、20 mg·L^-1 6-BA和20 mg·L^-1 KMnO₄）进行促发萌条试验。结果表明,白桦幼苗初次截干（30 d后）采条,截干高度10 cm进行激素KT、6-BA处理的白桦苗萌芽率最高,达65.0%以上;锯末保湿处理下3种截干高度萌条率、萌条产量均较高,萌条率达75.0%以上。枝条中总三萜含量以截干高度20 cm处理下最高,达76.43 mg·g^-1,其次为截干高度10 cm处理下,其他处理均不利于总三萜积累。叶中总三萜含量以截干高度30 cm下激素6-BA处理最高,达91.16 mg·g^-1,是锯末处理（30 cm）的2.68倍。在锯末处理、KT和KMnO₄处理下的枝条和叶片中总三萜含量显著低于其他处理。6-BA对枝条、叶片中齐墩果酸的积累有利,其他处理均不利于齐墩果酸积累。锯末处理有利于二次萌条及产量的提高,截干高度为10 cm处理下萌条产量达126.96 g。枝条总三萜含量以截干高度20 cm进行激素6-BA处理效果较好,达97.99 mg·g^-1。叶中总三萜含量以截干高度30 cm进行激素KT处理最佳,达99.22 mg·g^-1,其次为锯末处理组和6-BA处理组。该研究结果为可持续、高效的利用白桦资源及获得三萜产物提供了技术支持。     

不同密度下凤仙花重要形态性状与花朵数的关系

对30cm×30cm和50cm×50cm种植密度下的凤仙花(Impatiens balsamina L.)的地径、株高、冠幅、叶面积、花期、花径、一级分枝数、二级分枝数、一级分枝部位高和二级分枝部位高10个重要形态性状与花朵数的关系差异进行了相关性及通径分析,为凤仙花栽培与性状选择提供科学基础。结果表明:30cm×30cm种植的凤仙花的一级分枝数、二级分枝部位高都与花朵数呈显著正相关,地径、冠幅、二级分枝数与花朵数呈极显著正相关,对花朵数的直接效应大小顺序为:二级分枝数>一级分枝数>花径>花期;50cm×50cm种植的凤仙花,其地径、冠幅和二级分枝数都与花产量呈显著正相关,对花朵数的直接效应大小顺序为:二级分枝数>冠幅。二级分枝数对两种密度栽培的凤仙花花产量都起着重要作用。不同种植间距下凤仙花采用了不同的适应方式以获得最大花朵数目,进而获得最大数量的种子,获得较多的繁殖机会。在30cm×30cm下,是通过获得较多一级分枝数;在50cm×50cm下,是通过增加冠幅来产生较大花产量,而且与前者相比,植株茎秆粗壮,对霜霉病的抗性也强,因此,在栽培中,应以适合的低密度栽培比较好。

该研究用双因素裂区设计,在四种栽培模式和两种类型复合肥条件下,分析了玉米杂交种隆平206的农艺性状及干物质积累的影响。隆平206的株高、生长率均在等行距和宽窄行间差异不显著,但与等行距一穴两株间差异显著;穗位高在等行距和宽窄行[(70+50)cm]间差异不显著,但与宽窄行[(90+30)cm]和等行距一穴两株间差异显著;茎粗在各处理间差异不显著,栽培模式对隆平206穗位上第1叶和穗下第1叶的叶夹角影响显著,对穗上第1叶的叶向值影响显著,对穗下第1叶的叶向值影响不显著,对不同时期穗位节和穗位上节的茎杆强度影响差异显著,对不同时期干物质积累影响差异显著。隆平206在宽窄行[(90+30)cm],地富原玉米专用复合肥时,隆平206农艺性状各指标达最佳状态,栽培模式对隆平206不同时期干物质积累影响差异显著,在拔节期、大喇叭口期、开花期、乳熟期、成熟期,隆平206在栽培模式宽窄行(70+50)cm时干物质积累量均最大。该研究结果为玉米杂交种隆平206的栽培管理和施肥提供了依据。     

深水免耕移栽稻草覆盖栽培模式对晚稻温室气体排放及产量的影响

为了全面评价南方双季稻"早水晚用"节水栽培模式的意义,通过大田小区试验研究了晚稻移栽期灌深水+免耕移栽+稻草覆盖节水栽培模式对产量与温室气体排放的影响。结果表明:与常规栽培相比,在水稻齐穗期,节水栽培模式提高了9.6%~15.2%的光合速率(P0.01),但单叶水分利用率降低了13.3%~17.4%(P0.01);节水栽培模式降低了每穗总粒数和结实率,导致减产显著(P0.05);灌水深20 cm的甲烷排放量较对照减排了6.1%,而灌水深15和10 cm分别增排了6.5%和4.0%,同时灌水深20和15 cm节水模式较对照增排了N2O;灌水深20 cm节水模式的增温潜势和单位产量CO2排放当量均低于常规灌溉。因此,在南方稻区晚稻生产采用"移栽期蓄水深20 cm+免耕移栽+稻草覆盖节"节水栽培模式可以确保晚稻种植,同时减排温室气体,具有良好的经济生态效益。     

黄土丘陵区香梨园土壤水分、养分分布特征及其与产量的关系

本研究以晋西黄土丘陵区玉露香梨种植下的3种不同坡位坡耕地土壤为对象,对不同坡位、不同生育期、不同深度的土壤水分、养分和产量进行观测分析。结果表明: 不同坡位中,香梨产量为高坡位>中坡位>低坡位,高坡位香梨产量与土壤含水量(SWC)、有机质(SOM)、速效钾(AK)显著相关,其中AK对产量的影响最显著,中、低坡位香梨产量与SWC、SOM、全氮(TN)显著相关,其中SWC对产量的影响最显著;高坡位SWC、SOM、速效磷(AP)和TN含量高于中、低坡位,而中坡位AK含量最高。不同土层深度中,土壤养分含量在0～20 cm最高,20～40 cm最低,而SWC在0～20 cm显著低于其他土层,在20～40 cm最高。不同生育期中,开花期SOM、AP和TN含量最高,结果期SWC最高,成熟期AK含量最高。建议该区域在今后香梨水肥管理中,开花期高坡位应加强对K肥的施用,结果期以N、P复合肥施用为主。在中、低坡位应增加灌溉量,灌溉量在300 m³·hm^-2可有效降低该区域水分对产量的限制。本研究可为黄土丘陵区香梨种植精准灌溉和科学施肥提供理论支持和数据参考。     

不同种植行距的大穗型小麦品种'兰考矮早八'中几种与旗叶衰老有关的生理指标变化

在大田高产栽培条件下,检测不同种植行距的大穗型小麦品种‘兰考矮早八’开花后与旗叶衰老相关生理指标以及产量性状的结果表明,相对于传统行距为20cm而言,‘兰考矮早八’种植行距缩至15cm的花后旗叶中叶绿素降解减慢,丙二醛（MDA）含量下降,抗氧化系统酶活性增强,功能叶衰老减缓,穗粒重提高;行距缩至10cm时,尽管灌浆中后期过氧化物歧化酶（SOD）活性增强,但过氧化氢酶（CAT）和过氧化物酶（POD）活性下降,花后旗叶中叶绿素降解加快,MDA含量升高,植株衰老加快,穗粒重下降。     

遮阴和种植密度对东北春玉米穗部发育和植株生产力的影响

探讨遮阴对玉米穗部特性的影响及其产量效应,可以为应对气候变化与密植栽培条件下的玉米品种选育和高产栽培提供参考依据.本研究选用2个品种(紧凑型‘中单909’、平展型‘内单4’)和2个种植密度(4.5、9.0万株·hm^-2),在吉林省公主岭市开展田间遮阴试验,设置遮阴(遮阴度65%,小喇叭口期-成熟期)和不遮阴(对照)2个处理,研究遮阴和种植密度对不同株型玉米的穗部发育和植株生产力的影响.结果表明: 遮阴显著影响春玉米雌穗发育,造成散粉和吐丝期推迟,导致散粉吐丝间隔期延长3～15 d;遮阴显著降低春玉米干物质积累,籽粒产量下降50%以上(50.8%～87.0%);密植条件下春玉米穗部特性和产量性能受遮阴的影响显著高于稀植栽培;不同玉米品种相比,紧凑型品种的穗部特性和产量受遮阴和种植密度的影响低于平展型品种,紧凑型品种对生态环境变化的适应性较强,耐阴性和耐密性表现出一致性.

Row spacing effects of N2-fixation,N-yield and soil N uptake of intercropped cowpea and maize

In the tropics, cowpea is often intercropped with maize. Little is known about the effect of the intercropped maize on N₂-fixation by cowpea or how intercropping affects nitrogen fertilizer use effiency or soil N-uptake of both crops. Cowpea and maize were grown as a monocrop at row spacings of 40, 50, 60, 80, and 120 cm and intercropped at row spacing of 40, 50, and 60 cm. Plots were fertilized with 50 kg N as (NH₄)₂SO₄; microplots within each plot received the same amount of¹⁵N-depleted (NH₄)₂SO₄. Using the¹⁵N-dilution method, the percentage of N derived from N₂-fixation by cowpea and the recovery of N-fertilizer and soil N-uptake was measured for both crops at 50 and 80 days after planting.Significant differences in yield and total N for cowpea and maize at both harvest periods were dependent on row spacing and cropping systems. Maize grown at the closer row spacing accumulated most of its N during the first 50 days after planting, whereas maize grown at the widest row spacing accumulated a significant portion of its N during the last 30 days before the final harvest, 80 days after planting.Overall, no significant differences in the percentage of N derived from N₂-fixation for monocropped or intercropped cowpea was observed and between 30 and 50% of its N was derived from N₂.At 50 DAP, fertilizer and soil N uptake was dependent on row spacing with maize grown at the narrowest row spacing having a higher fertilizer and soil N recovery than maize grown at wider spacings. At 50 and 80 DAP, intercropped maize/cowpea did not have a higher fertilizer and soil N uptake than monocropped cowpea or maize at the same row spacing. Monocropped maize and cowpea at the same row spacing took up about the same amount of fertilizer or soil N. When intercropped, maize took up twice as much soil and fertilizer N as cowpea. Apparently intercropped cowpea was not able to maintain its yield potential.Whereas significant differences in total N for maize was observed at 50 and 80 DAP, no significant differences in the atom %¹⁴N excess were observed. Therefore, in this study, the atom %¹⁴N excess of the reference crop was yield independent. Furthermore, the similarity in the atom %¹⁴N excess for intercropped and monocropped maize indicated that transfer of N from the legume to the non-legume was small or not detectable.     

Effect of inorganic fertilizer and farmyard manure on soil physical properties, root distribution, and water-use efficiency of soybean in Vertisols of central India

A field experiment was conducted on a Vertisol for three consecutive years (1998-2000) to study the effects of combined use of inorganic fertilizer (NPK) and organic manure (farmyard manure) on soil physical properties, water-use efficiency, root growth and yield of soybean [Glycine max (L.) Merr.] in a soybean-mustard cropping system. Application of 10 Mg farmyard manure and recommended NPK (NPK+FYM) to soybean for three consecutive years improved the organic carbon content of the surface (0-15 cm) soil from an initial value of 4.4 g kg(-1) to 6.2 g kg(-1) and also increased seed yield and water-use efficiency by 103% and 76%, respectively, over the control. The surface (0-15 cm) soil of the plots receiving both farmyard manure and recommended NPK had larger mean weight diameter (0.50 mm) and a higher percentage of water stable aggregates (55%) than both the inorganically fertilized (NPK) (0.44 mm and 49%) and unfertilized control plots (0.41 mm and 45.4%). The saturated hydraulic conductivity (13.32 x 10(-6) m s(-1)) of the NPK+FYM treatment of the 0-7.5 cm depth was also significantly greater than that of the NPK (10.53 x 10(-6) m s(-1)) and control (8.61 x 10(-6) m s(-1)) treatments. The lowest bulk density (1.18 Mg m(-3)) in the 0-7.5 cm layer was recorded in NPK+FYM whereas it was highest in the control plots (1.30 Mg m(-3)). However, at sub-surface (22.5-30 cm) layer, fertilizer and manure application had little effect on bulk density and saturated hydraulic conductivity. Root length density (RLD) up to the 30 cm depth was highest in the NPK+FYM plots and it was 31.9% and 70.5% more than NPK and control plots. The RLD showed a significant and negative correlation (r=-0.88( * *)) with the penetration resistance.     

行距配置对晚熟冬麦区群体结构与光合性能的影响

合理的行距配置可以调节群体冠层结构的光合作用。山西太谷冬小麦产量徘徊不前,为了研究晚熟冬麦区不同行距配置对不同穗型冬小麦光合性能与群体结构的影响,在大田条件下选用两种不同穗型品种,在播量一致的前提下,分别采用10 cm和20 cm两种行距配置,研究冬小麦群体结构、光能利用和产量结构的差异。研究结果表明:全生育期总LAI值表现为B2高于B1,10 cm行距配置改变了叶片的垂直分布,尤其对多穗型小麦品种冠层(60-80 cm)叶面积的提高最为明显。在小麦植株中、上部分45-90 cm处,两种行距配置LI%均表现为B2配置大于B1配置,在株高60-75 cm处,两种行距配置LI%差异最为明显,B2配置较B1配置LI%提高达30%以上。花后旗叶PN和孕穗期至蜡熟期群体NPR均表现为10 cm行距配置高于20 cm行距配置。四个处理的总干物质重、绿叶、茎和穗的干物质重均表现为B2B1行距配置。两个小麦品种的B2处理(10 cm行距配置)的产量和生物产量均极显著高于B1处理(20 cm行距配置);但经济系数则呈现B2处理(10 cm行距配置)均小于相应小麦品种的B1处理。行距配置对不同小麦品种的影响不大。表明10 cm行距配置适用于北方晚熟冬麦区。     

不同株行距配置对夏大豆群体结构及光截获的影响

以田间试验(2006—2007年)为基础,分析了地上部干物质、叶面积指数(LAI)、光合有效辐射(PAR)、光能利用率和植株形态指标变化特征,夏大豆‘鲁豆4号’(Glycine maxcv.Ludou 4)在同一密度(3.09×105株/hm2)下设5种株行距配置方式,即行距×株距分别为18 cm×18 cm(A)、27 cm×12 cm(B)、36 cm×9 cm(C)、45 cm×7.2 cm(D)、54 cm×6 cm(E)。结果表明,大豆在生育期间干物质变化因株行距不同而产生差异,2006和2007生长季的各处理干物质分别在播种后第70天和90天达到最高,播种后第80天和100天时,A处理比E处理分别高21.6%和34.0%;不同层次干物质积累重心随行距加大有上移趋势。各处理LAI随行距扩大、株距减少有下降趋势,其中,A和B处理LAI表现较稳定,LAI相对较高且时间较长。光能利用率随行距加大有降低趋势,A和B处理显著高于E处理(P0.05)。夏大豆在不同株行距配置下,株粒数、百粒重与产量相关系数分别为0.941*和0.926*(2006年),0.995*和0.892*(2007年),随行距变小PAR透射率降低、截获率和光能利用率上升而产量增加,A和B处理产量显著高于E处理(P0.05)。说明夏大豆在雨养农业条件下,植株相对均匀分布可改善群体结构和增强光截获,进而提高群体光能利用率和产量。     

不同种植密度下玉米与豌豆间作对群体总产量的影响

于2014和2015年在黄土高原半干旱区全膜覆盖种植技术下,研究了不同种植密度下玉米行内间作豌豆对作物群体总产量的影响.结果表明: 2014年,当玉米株距为40和50 cm时,与不插播相比,在玉米株间插播2株豌豆显著提高了作物群体籽粒总产量;而在株距60 cm情况下,插播豌豆对作物群体总产量无显著影响.2015年,玉米株距40和50 cm情况下,与对应株距的单作玉米相比,在玉米株间插播2株豌豆对群体籽粒总产量无显著影响;但是在玉米株距60 cm的情况下,株间插播2株豌豆使作物群体籽粒总产量显著增加.导致两个试验年份之间玉米行内间作豌豆的产量效应差异的主要原因是生长季降水量在2014年较2015年充沛.综合比较,玉米株距40 cm、株间插播2株豌豆间作形式的籽粒总产量最高.此外,在玉米单作和行内间作中,籽粒总产量均随玉米株距的增大而减小.     

翻压山黧豆绿肥与氮肥减施对水稻生长及其养分吸收与产量的影响

为探明种植翻压山黧豆绿肥与减施氮肥下的水稻生产潜力,通过3年田间定位试验,设置冬闲+不施肥(NF)、山黧豆绿肥(GM)、冬闲+常规氮肥(100%N,CK)、山黧豆绿肥+80%常规氮肥(GM+80%N)、山黧豆绿肥+70%常规氮肥(GM+70%N)、山黧豆绿肥+60%常规氮肥(GM+60%N)6个处理,研究不同处理对水稻生长、养分吸收及产量的影响。结果表明：(1)与CK相比,翻压山黧豆绿肥并减施氮肥处理均能够显著提升水稻株高、增加水稻分蘖数、提高水稻干物质积累量,其中以GM+70%N施肥处理提升效果最为明显。(2)GM+70%N施肥处理下,不同生育时期水稻株高、有效分蘖数分别较对照常规施肥(100%N)提升了13.32%~ 15.73%和33.98%~59.47%,水稻干物质积累量提高了23.19%~144.18%,且随着生育时期的推进增加速率依次降低。(3)种植翻压山黧豆绿肥并减施氮肥处理下水稻产量均有所提高,其中GM+70%N和GM+80%N处理显著提高,增产分别达13.84%,7.25%,且GM+70%N处理下水稻植株和籽粒养分吸收更为全面。研究发现,种植翻压山黧豆并适量减施氮肥能有效促进水稻生长和养分的吸收积累,显著提高水稻产量,说明翻压山黧豆绿肥可替代稻田30%~40%的氮肥施入量,并可在避免水稻旺长的同时实现水稻高产,是四川水稻种植较好的耕作措施。     

小麦行距配置对套种花生生理特性和产量的影响

以大花生品种早熟型‘山花108’和晚熟型‘780-15’为试验材料,设置小麦3种行距配置(25 cm、30 cm、大小行40 cm+20 cm)和2种花生种植方式(麦套、夏直播),探讨不同种植模式对夏花生产量构成、光合特性、抗氧化活性和干物质积累与分配的调控作用.结果表明: 适当扩大小麦行距、相同平均行距下选用大小行种植,可提高套种花生荚果产量和籽仁产量,增大叶面积指数和干物质积累量,增强光合能力,同时提高超氧化物歧化酶、过氧化物酶和过氧化氢酶活性,降低丙二醛含量.麦套花生产量高于夏直播花生并且以大小行处理产量最高.与小麦行距30 cm相比,大小行处理山花108和780-15两品种花生荚果产量和籽仁产量分别提高6.3%、13.3%和7.7%、16.5%.表明大小行种植有助于扩大光合面积,提高净光合速率,增加干物质积累量,同时缓解花生植株个体与群体间的矛盾,延缓衰老,从而提高麦套花生产量.     

Growth responses and essential oil profile of Salvia officinalis L. Influenced by water deficit and various nutrient sources in the greenhouse

Salvia officinalis L. is a medicinal plant extensively used in foods, traditional medicine, and the pharmacological industry. In the current study, the effects of different irrigation regimes [irrigation after 70 ± 5 (regular), 105 ± 5 (moderate drought stress), and 140 ± 5 (severe drought stress) mm evaporation] and nutrient sources (control, NPK, farmyard manure, foliar fertilizer, and hydrogel) were investigated on the growth parameters and essential oil (EO) components of S. officinalis in the greenhouse. The plants were harvested two times. The regular irrigation treatment had the most significant effect on plant height (51 cm), fresh and dry herb weight (51.5 and 18.1 g plant⁻¹), and fresh and dry leaf weight (40.1 and 13.1 g plant⁻¹). The highest amount of EO was observed after moderate drought stress (1.48%). The NPK treatment had the greatest effect on plant height (40 cm), branch number (19 per plant), fresh and dry herb weight (53.4 and 18.9 g plant⁻¹), fresh and dry leaf weight (41.2 and 13.6 g plant⁻¹), and EO content (1.67%). The 1^st cutting was superior in EO amount, while the 2^nd cutting had a high agronomic yield. α-Thujone (from 21.6 to 34.2%) was identified as the predominant compound. Additionally, the content of α-thujone in the 2^nd cutting was higher after moderate drought stress, NPK, and hydrogel treatments. Moreover, 1,8-cineole, β-thujone, camphene, α-pinene, α-humulene, viridiflorol, borneol, and bornyl acetate were the other main compounds. As a general result, regular irrigation and NPK treatments improved the agronomic yield of S. officinalis. The plants under drought stress produced high amounts of EO. The farmyard manure also improved plant yield by providing a part of the plant's nutritional needs. Therefore, it could be concluded that it is crucial to determine the effects of limited water availability and various nutrient sources on yield and chemical compositions for medicinal and aromatic plant growth.     

Long-Term Effect of Manure and Fertilizer on Soil Organic Carbon Pools in Dryland Farming in Northwest China

An understanding of the dynamics of soil organic carbon (SOC) as affected by farming practices is imperative for maintaining soil productivity and mitigating global warming. The objectives of this study were to investigate the effects of long-term fertilization on SOC and SOC fractions for the whole soil profile (0–100 cm) in northwest China. The study was initiated in 1979 in Gansu, China and included six treatments: unfertilized control (CK), nitrogen fertilizer (N), nitrogen and phosphorus (P) fertilizers (NP), straw plus N and P fertilizers (NP+S), farmyard manure (FYM), and farmyard manure plus N and P fertilizers (NP+FYM). Results showed that SOC concentration in the 0–20 cm soil layer increased with time except in the CK and N treatments. Long-term fertilization significantly influenced SOC concentrations and storage to 60 cm depth. Below 60 cm, SOC concentrations and storages were statistically not significant between all treatments. The concentration of SOC at different depths in 0–60 cm soil profile was higher under NP+FYM follow by under NP+S, compared to under CK. The SOC storage in 0–60 cm in NP+FYM, NP+S, FYM and NP treatments were increased by 41.3%, 32.9%, 28.1% and 17.9%, respectively, as compared to the CK treatment. Organic manure plus inorganic fertilizer application also increased labile soil organic carbon pools in 0–60 cm depth. The average concentration of particulate organic carbon (POC), dissolved organic carbon (DOC) and microbial biomass carbon (MBC) in organic manure plus inorganic fertilizer treatments (NP+S and NP+FYM) in 0–60 cm depth were increased by 64.9–91.9%, 42.5–56.9%, and 74.7–99.4%, respectively, over the CK treatment. The POC, MBC and DOC concentrations increased linearly with increasing SOC content. These results indicate that long-term additions of organic manure have the most beneficial effects in building carbon pools among the investigated types of fertilization.
