soil moisture supply的意思|示意

Recent achievements of appropriate soil moisture and lower limit of soil drought indices provided an important basis of soil physics for agricultural water supply of low quota.

土壤适宜含水量和土壤干旱下限指标的最新研究成果，为低定额的农业供水提供了土壤物理学的重要依据。

The results were as follows:(1) The ramets density and population biomass at high level of soil moisture supply were higher than that of the population at low level of soil moisture supply.

结果表明：①土壤水分有效性高的种群，其子株密度和生物量大于土壤水分有效性低的种群。
