通过药剂比较试验，筛选出适合枣树化学疏花疏果药剂：萘乙酸４０ ｍｇ·１~（－１）十磷酸二氢钾３ ０００ ｍｇ·１~（－１）和萘乙酸 ５０ ｍｇ·１~（－１）盛花末期进行疏花疏果可明显促进果实生长发育，减轻中、后期生理落果，平均果重增加，产量提高。
Through chemical comparative experiments, the chemical thinning and thinning agent suitable for jujube tree was screened: naphthalene acetic acid 40 mg · 1 -1 potassium dihydrogen phosphate 3 000 mg · 1 -1 and naphthalene acetic acid 50 mg · 1 ~ (-1) Flowering thinning and fruit thinning at the end of flowering can obviously promote the growth and development of fruits, reduce the physiological drop of fruits in the middle and later stages, increase the average fruit weight, and increase the yield.
