field maximum moisture capacity meaning in English

田间最大持水量

The variation curves of yield and grain protein content with soil water content ( or nitrogen ) were convex in high fertility ( or soil water content were 70 % and 80 % of field maximum moisture capacity ) , and the soil water content ( or nitrogen levels ) before maximum protein content ( or maximum yield ) were the soil water content ( or nitrogen levels ) of coordinated variation of yield and grain protein content . [ conclusion ] coordinated variation of yield and grain protein content was possible in suitable condition
在高肥和土壤水分含量为田间最大持水量的70 %和80 %条件下，产量和蛋白质含量曲线均为凸型，蛋白质含量达到最大值之前对应的土壤水分含量为高肥条件下产量和蛋白质含量协同变化区间；产量达到最大值之前对应的施氮量为土壤水分含量为田间最大持水量的70 %和80 %条件下产量和蛋白质含量协同变化区间。
