| 摘 要： | 根据黑土长期肥料试验1985～1995年期间的作物分析资料,研究了施肥和作物生长状况对大豆、玉米、小麦3种作物体内养分浓度、养分在籽实和秸秆中分配比以及形成1000kg籽实产量的收获养分量等参数的影响,结果表明,在本试验的正常施肥条件下,上述参数十分稳定,受施肥和作物生长状况的影响不大,可直接用于这一地区养分收支的估算

| Abstract: | Based on a long-term fertilization experiment from 1985 to 1995,the effect of fertilization and crop growing status on the parameters as nutrient concentration of crops,distribution ratio of nutrients in grain and in stalk,and harvested nutrients for producing 1000kg grain products of soybean,maize,and wheat crops were studied.The results indicated that under the normal fertilization condition,the parameters mentioned above were quite stable.Therefore,the parameters obtained from this study can be used for the calculation of nutrient budget of the farmland in this region. |
