為了栽培的持續(xù)健康進(jìn)行,在永久凋萎點(diǎn)之前要制訂有效的灌溉日程計(jì)劃.
這是消耗允許值（AD）.適當(dāng)?shù)耐寥莱炙芰ο脑试S值水平需要通過實(shí)驗(yàn)和判斷來進(jìn)行選擇.這種選擇要基于耕作方式、植物種類、土壤結(jié)構(gòu)及季節(jié)等因素.植被覆蓋中等的土壤持水能力允許消耗值一般為50%,而植物覆蓋率低的土壤持水能力允許消耗值通過為75%.

For continued healthy growth,an efficient schedule plans irrigation well before PWP.This is the allowable depletion(AD).Experimentation and judgment are needed to select a reasonable AD level of the soil reservoir capacity,which is based on the value of the planting,plant type,soil texture,and the season.A medium-value turf is typically managed at 50%AD,whereas a low-value turf could have an AD of 75% of the soil reservoir capacity.
