摘要
本试验研究了水稻孕穗后期黄叶干尖发生的土壤条件和施氮磷钾、水溶、构溶磷比例以及石灰量的计算方法等。
The factors responsible for yield reduction caused by leaf yellowing and leaf tip dryingat booting stage were found to be soil conditions,N:P ratio and the ratio of water solubleto citric soluble phosphorus.A method for calculation of the amount of lime to be appliedwas proposed in the paper.
