江西省潜育化水稻土,往往受地下水顶托或土壤板结和耕作层下存在隔水层的影响,渗漏量很小,对获得水稻高产十分不利。本试验目的在于:(1)探索早稻不同生育阶段的土壤适宜渗漏量;(2)土壤渗漏量对水稻生长发育和产量的效应;(3)渗漏量对土壤理化性质的影响。试图用土壤渗漏量作为潜育化水稻土治理中的一个指标。
The gneissic paddy soil in Jiangxi Province is often affected by the presence of aquitards beneath the groundwater jacking or soil compaction and tillage. The amount of leakage is very small, which is very unfavorable to the high yield of rice. The purpose of this experiment is to: (1) explore the suitable soil leakage at different growth stages of early rice; (2) the effect of soil leakage on the growth and yield of rice; and (3) the impact of leakage on soil physical and chemical properties. Attempts to use soil leakage as an indicator of gob soil management.
