茶园间作不同绿肥对节肢动物群落结构和多样性的影响

【目的】研究在茶园中合理间作绿肥对茶园节肢动物群落结构和多样性的影响。【方法】本文在茶园中分别设间作铺地木兰+罗顿豆、圆叶决明+白三叶、白三叶+平托花生3种不同绿肥组合处理,并设不间作绿肥、常规除草的茶园为对照。【结果】间作不同绿肥均能提高茶园节肢动物群落的物种丰富度和群落多样性,提高茶园捕食性天敌昆虫、蜘蛛和寄生性天敌在茶园冠层群落的比率;不同处理茶园冠层节肢动物Shannon-wiener多样性指数(H)、Simpson指数(D)和均匀度指数变化趋势基本一致;茶冠层的节肢动物群落多样性指数在4类不同处理茶园间差异显著;间作绿肥增加了茶园的生物多样性,4类不同处理茶园茶冠层群落相似性系数在0.741~0.892之间,表明4类不同处理茶园冠层群落在物种组成上有较高的相似性。4类不同处理茶园害虫与天敌两类群功能团的丰盛度之间成显著的正相关,表明天敌对害虫的空间数量跟随效应强,主要表现为二者数量间的相互作用。灰色关联度分析表明在4类不同处理茶园中的群落节肢动物物种数/个体数、天敌物种数/害虫物种数、害虫丰富度与多样性指数和均匀度指数的关联系数较高,反应了群落的多样性和稳定性。【结论】间作增强了茶园群落的生物多样性,提高害虫天敌的种类和个体数,有利有效发挥天敌对有害生物的生态控制。     

间作牧草对茶园螨类群落多样性的影响

螨类是茶园生态系统中重要且复杂的类群之一.为了了解不同植物问作后对茶园螨类群落的组成结构和多样性的影响,2006年3月至2008年4月,在武夷山市星村镇大坪洲茶园通过间作百喜草(Paspalum notatum)或圆叶决明(Cassia rotundifolia)、留养杂草和除杂草4种不同处理,对茶园茶冠层(采用盆拍法及剪枝条法)和凋落层(采用捡取凋落物法)的螨类进行系统采样、标本鉴定和统计分析.结果表明:与留养杂草对照相比,间作百喜草或圆叶决明均显著增加了茶冠层和凋落层捕食螨的物种丰富度(S)、有效多样性指数(eH')、个体数(M和绝对丰度(-/n).与留养杂草和除杂草这两种对照相比,间作百喜草或圆叶决明均显著增加了茶冠层和凋落层优势种圆果大赤螨(Anystis baccarum)的个体数(N).荼冠层植食螨和腐食螨及凋落层腐食螨的所有群落指标在不同处理茶园间均无显著差异.茶冠层和凋落层螨类群落物种丰富度(S)和个体数(N)季节性变化明显,物种组成相似性高.间作茶园和留养杂草茶园茶冠层的螨类总个体数与其对应的凋落层螨类总个体数呈显著正相关.多样化茶园有利于保护和利用捕食螨,从而对茶园有害生物进行生态控制,促进有机茶叶可持续生产.

不同生境条件与管理方式对茶园蜘蛛群落结构及多样性的影响

蜘蛛在茶园的生态控制和生物防治中起到重要的作用,为了解不同生境条件和管理方式的茶园蜘蛛群落结构差异和多样性变化,于2011年3月份—2011年10月份,运用振落承接和过筛法对3种不同类型茶园的蜘蛛群落组成与多样性进行了调查。结果表明:(1)3种类型茶园蜘蛛群落组成:3种类型茶园蜘蛛群落在科、属、种的组成及个体数量上,均表现为有机茶园高,无公害茶园次之,普通茶园低,且在物种数和个体数存在显著差异。管巢蛛科和狼蛛科是3种类型茶园的优势类群,球蛛科、跳蛛科、狼蛛科、皿蛛科的物种优势度大于10%。(2)蜘蛛群落物种多样性的多重分析结果表明,有机茶园蜘蛛群落的个体数、物种数、物种多样性指数、物种丰富度指数和均匀度指数均高于无公害茶园和普通茶园,普通茶园最低,且达到显著水平(P0.05)。(3)多元数据分析结果表明,有机茶园蜘蛛群落组成与普通茶园差异较大,无公害茶园与普通茶园蜘蛛群落组成差异较小;3种类型茶园的茶丛蜘蛛群落个体数、物种数及物种多样性指数、丰富度指数和均匀度指数均高于地表,且表现为机茶园多,无公害茶园次之,普通茶园最少。蜘蛛的功能群采集发现,在3种茶园中结网蜘蛛少,而主要是游猎蜘蛛。(4)不使用化学农药的茶园,因其周边生境结构复杂(竹林、小灌木及杂草),植被丰富,形成植被缓冲带,改善了茶园小气候环境,增加了茶园土表覆盖度,可明显提高茶丛和地表游猎蜘蛛的物种数和个体数量。综合研究结果表明,在生态条件好、干扰少的有机茶园中的蜘蛛物种数量、群落多样性明显高于受损生态系统和人为干扰强的普通茶园。     

茶园间作柑桔杨梅或吊瓜对叶蝉及蜘蛛类群数量和空间格局的影响

为评价茶园间作几种常见经济作物对重要害虫假眼小绿叶蝉及其主要天敌蜘蛛类群数量和空间格局的影响,遂选乌牛早品种纯茶园、乌牛早分别与柑桔、杨梅和吊瓜的间作茶园、以及安吉白茶与吊瓜间作茶园,2007年9月上旬—2008年12月下旬,每旬1次调查茶丛上、中、下层叶蝉和各种蜘蛛的数量。结果表明:(1)与纯茶园相比,间作茶园叶蝉种群数量和蜘蛛类群个体数量显著地增加,间作茶园蜘蛛种数显著地增加;(2)间作茶园茶丛上、中、下层叶蝉、蜘蛛个体数量分布明显区别于纯茶园茶丛上、中、下层叶蝉、蜘蛛个体数量分布;(3)茶丛上层的嫩梢是制作高档茶的原料,而纯茶园茶丛上层叶蝉虫口百分率为54.16%,间作茶园茶丛上层叶蝉虫口百分率皆减小,并且叶蝉高峰期间蜘蛛的跟随效应增强;(4)间作增加了经济收入并减少了防治次数。认为:(1)间作可在一定程度上调控叶蝉种群、蜘蛛类群的数量和空间格局;(2)间作可减轻叶蝉为害造成的产值损失,增强了茶园群落对于叶蝉的自然控制潜能。

通过田间小区试验,研究了小麦与蚕豆间作对蚕豆枯萎病发生和根际微生物代谢功能多样性的影响。结果表明,小麦与蚕豆间作使蚕豆枯萎病的发病率和病情指数分别比单作显著降低20%和30.4%。与单作处理相比,间作显著增加了蚕豆和小麦根际微生物对31种碳源的平均利用率（AWCD）,其中间作蚕豆的AWCD值最高,比单作增加82.7%,单作蚕豆最低。间作蚕豆和间作小麦根际微生物的Shannon多样性指数与丰富度指数均显著高于单作,间作使蚕豆和小麦的丰富度指数分别增加29.2%和30.3%。根际微生物对六类碳源的利用强度百分比以糖类、羧酸类和氨基酸最高,分别为41.96%,19.80%和18.13%。主成分分析表明,小麦与蚕豆间作改变了根际微生物的群落组成;相关分析表明,糖类、羧酸类和氨基酸类碳源是区分单间作处理差异的主要碳源,其中氨基酸类碳源是最敏感的碳源。小麦与蚕豆间作增加了根际微生物活性,提高了Shannon多样性指数和丰富度指数,改变了微生物群落功能多样性,是抑制蚕豆枯萎病的有效措施。该研究为阐明根际微生物功能多样性变化在间作体系病害控制中的作用与机制奠定了理论基础。     

Effects of intercropping systems on community composition and diversity of predatory arthropods in vegetable fields

Field trials were carried out on Langqi Island, Fujian, PR China in 2004, to determine the effects of intercropping Chinese cabbage (Brassica chinensis) with green cabbage (Brassica oleracea), garlic (Allium sativum) and lettuce (Lactuca sativa), on community composition and diversity of predatory arthropods in vegetable fields. Two intercropping plots were designed and used in this study. In plot 1, two ridges of Chinese cabbage were intercropped with one ridge of garlic (CG1), lettuce (CL1) or green cabbage (CB1). In plot 2, the Chinese cabbage was planted in the center (100 cm wide) of the ridge, and under-sown with garlic (CG2), lettuce (CL2) or green cabbage (CB2) on both edges (25 cm wide) of the same ridge. A monoculture plot of the Chinese cabbage (CK) was arranged for comparison with plots 1 and 2. The highest species richness was found in CG1, and the lowest in CK. The highest abundance was found in CL1 (141.67 predators/plot), whereas the lowest was in CB1 (97.67 predators/plot). With the exception of CL1, significantly higher diversity indices were found in intercropping treatments than in CK. The majority of spiders sampled from fields were from families Theridiidae (34.04%) and Lycosidae (30.57%). These findings suggest that Chinese cabbage intercropped with non-cruciferous crops might increase species richness, abundance and diversity of the arthropod community in general and predators in particular.

The impact of maize-bean intercropping on insect biodiversity

Intensive agriculture is one of the main reasons for recent insect declines. This loss of biodiversity has created the need to develop methods of intensive cultivation that combine high yields with biodiversity conservation. One promising method in maize cultivation is intercropping with beans. The objective of this study was to determine whether maize-bean intercropping could increase insect biodiversity. We examined the activity density, species richness and Shannon diversity of bees and carabid beetles in pure and intercropped maize under both organic and conventional management. We collected carabid beetles using pitfall traps and bees by doing transect walks. The study was carried out in an agricultural landscape, on a set of 17 study sites. We found that intercropping leads to significant increases in bumblebee and honeybee activity as well as in bee species richness. Differences between pure and intercropped maize were dependent on the year of data acquisition and the management style. Solitary wild bee species activity was not significantly affected. Carabid activity density and carabid species richness also did not differ significantly between the cropping systems. We conclude that maize-bean intercropping can contribute to insect biodiversity conservation but its contribution is limited to bumblebees. Despite its relatively low contribution per hectare, maize-bean intercropping could have a surprisingly positive impact, as maize now covers large areas of German farmland. Potential exists to increase the biodiversity value of maize intercropping even further by using varied plant mixes. Our results strongly encourage further research in this direction.     

The effects of long-term nitrogen loading on grassland insect communities

Just as long-term nitrogen loading of grasslands decreases plant species richness and increases plant biomass, we have found that nitrogen loading decreases insect species richness and increases insect abundances. We sampled 54 plots that had been maintained at various rates of nitrogen addition for 14 years. Total insect species richness and effective insect diversity, as well as herbivore and predator species richness, were significantly, negatively related to the rate of nitrogen addition. However, there was variation in trophic responses to nitrogen. Detritivore species richness increased as nitrogen addition increased, and parasitoids showed no response. Insect abundances, measured as the number of insects and insect biovolume (an estimate of biomass), were significantly, positively related to the rate of nitrogen addition, as were the abundances of herbivores and detritivores. Parasitoid abundance was negatively related to the rate of nitrogen addition. Changes in the insect community were correlated with changes in the plant community. As rates of nitrogen addition increased, plant species richness decreased, plant productivity and plant tissue nitrogen increased, and plant composition shifted from C₄ to C₃ grass species. Along this gradient, total insect species richness and effective insect diversity were most strongly, positively correlated with plant species richness. Insect biovolume was negatively correlated with plant species richness. Responses of individual herbivores varied along the nitrogen gradient, but numbers of 13 of the 18 most abundant herbivores were positively correlated with their host plant biomass. Although insect communities did not respond as strongly as plant communities, insect species richness, abundance, and composition were impacted by nitrogen addition. This study demonstrates that long-term nitrogen loading affects the entire food chain, simplifying both plant and insect communities. Received: 18 May 1999 / Accepted: 5 January 2000     

云南橡胶林和天然次生林枯落物层蚂蚁物种多样性、群落结构差异及指示种

橡胶树Hevea brasiliensis是云南省重要的经济林木, 但对其生态服务功能尚存在争议。本研究以天然次生林为对照, 使用Winkler法对橡胶林枯落物层蚂蚁进行初步研究, 探讨橡胶林枯落物层蚂蚁的生态状况。于2012年10月和2013年4月采用Winkler袋法调查了云南省绿春县大黑山乡橡胶林和牛孔乡天然次生林枯落物层蚂蚁群落的物种多样性、 群落结构差异及指示种。结果表明： 橡胶林枯落物层蚂蚁多度（转换后）、 物种丰富度S和ACE值显著低于无干扰的天然次生林（P<0.05）; 蚂蚁多度（转换后）显著低于有干扰的天然次生林（P<0.05）, 而物种丰富度S和ACE值差异不显著。橡胶林枯落物层蚂蚁群落结构与两种天然次生林都不相似（F=3.93, df=12, P<0.01）。橡胶林中流浪种大头蚁属Pheidole的蚂蚁种类与天然次生林相比, 物种丰富度增加了100%。天然次生林枯落物层中蚂蚁指示种有3种, 分别为刘氏隆头蚁Strumigenys lewisi、 黄足厚结猛蚁Pachycondyla luteipes和女娲角腹蚁Recurvidris nuwa, 而橡胶林枯落物层中指示种仅为菱结大头蚁Pheidole nodus。枯落物层蚂蚁物种多样性与枯落物厚度呈显著正相关, 而枯落物盖度仅与蚂蚁多度（转换后）有相关性。结果说明, 橡胶林经过长期的经营管理, 生态环境趋于稳定, 对枯落物层蚂蚁群落具有一定的保护作用, 但与天然次生林相比, 蚂蚁多度（转换后）及群落结构仍显示出明显的不同。
