三要素在各时期的吸收比例在图1中表示了幼茶在各时期三要素增加比率,氮与钾4—11月的各时期的吸收率都在年吸收量的20—30％,而磷在4—6月和9月吸收率高达40—50％,其它时期少许。根据这个调查与三要素在土壤中变化来 The absorption ratio of the three elements in each period is shown in Fig. 1. The rate of increase of three elements in young tea is shown in Fig. 1. The absorption rates of nitrogen and potassium in each period from April to November are both 20-30% of the annual absorption, and phosphorus In April-June and September absorption rate as high as 40-50%, other times a little. According to this survey and the three elements in the soil change
