1、肥水管理
1. The management of fat and water
对未结果树,每株可追施0.15~0.25公斤磷酸二铵;结果大树,可按第二年计划产量,每100公斤果追施纯氮0.7公斤、有效磷0.7公斤,幼树追肥可以明显增加翌年萌芽率。对盛果期大树,连年秋施肥料,在肥料数量、种类相同的情况下,与初夏追肥相比,每株树可增产50公斤左右。
For each tree, 0.15 to 0.25 kg of diammonium phosphate per plant could
be applied for each plant. As a result, the yield of second year plan
was second years, and 0.7 kg of pure nitrogen and 0.7 kg of effective
phosphorus were applied for every 100 kg of fruit, and the germination
rate of the young trees could be significantly increased in the
following year. Compared with early summer dressing, the yield of each
tree can be increased by 50 kg or so when the fertilizer is applied in
autumn.
秋季结合防治苹果病虫害,可喷0.3%~0.4%尿素加高磷高钾清液肥料(磷不低于350g/L,钾不低于150g/L)2次。10月中旬,在养分回流期叶面喷施0.3%的尿素一次。
In autumn, combined with the control of apple diseases and insect pests,
0.3% ~ 0.4% urea can be sprayed with high phosphorus and high potassium
clear liquid fertilizer (phosphorus is not less than 350g/L, and
potassium is not less than 150g/L) for 2 times. In mid October, 0.3%
urea was sprayed on the foliar of nutrient reflux stage.
