In the greenhouse, by conducting pot and field experiments, the diagnosis method of crop moisturecontent from variable differential in stem diameter of tomato was studied.
在温室条件下，盆栽和小区试验相结合，进行了用番茄株茎直径变差法诊断其水分状况的试验研究。

The rainfed field could provide a content yield, if the soil moisture condition of the first harvest I's IP is good.
这就要求灌溉时，尽量保证第一茬苜蓿生长初期的土壤含水量。

To a sample dryland soil in Chaoyang county, Liaoning province, computational result of critical soil moisturecontent for maize sowing is about 17.34% (gravity content), or 58.1% of field capacity.
