为了提高苹果梨的单株产量,必须增加其短果枝数和叶丛枝数,提高座果率.1982—1983年,我们结合苹果梨的矮壮修剪,进行了喷施接壮素的试验.试验在焉耆盆地中部农二师农科所果园和二十二团5农3号果园内进行.供试果树为34株7年生苹果梨(砧木为杜梨),树势基本相同.供试的矮壮素(河北邯郸峰峰矿厂生产)有效成分为50%,用超低量喷雾器喷于骨干枝上,
In order to improve the yield per plant of pear, it is necessary to increase the number of its short branches and the number of branches and leaves to increase the rate of fruit set in. In 1982-1983, we combined with the apple pear short pruning, spraying the test of nociceptin. The experiment was carried out in the orchard of Nong Er Er Shi Ke Nong Ke Yuan and Nong Nong No.3 Orchard in the middle of Yanqi Basin.The test fruits were 34 7-year-old apple pears Chlormequat (Hebei Handan Fengfeng mine production) active ingredient is 50%, sprayed with an ultralow amount of spray on the backbone of the branch,
