试验在山西省柳林县前元庄果园进行。供试品种为元帅、青香蕉、金冠等。用不同浓度的硼砂、防落素以及与尿素混喷的不同处理比较其座果率的效应。每处理选生长一致的3株树于盛花期喷布,另选3株作为对照。喷前在选定的树上选一大枝,调查其花序数、花朵数,生理落果后调查座果数。一、硼对提高苹果座果率的效应
The experiment was conducted in Qian Yuan Zhuang Orchard, Liulin County, Shanxi Province. Varieties for the Marshal, Green Banana, Golden Delicious and so on. The effect of fruit set rate was compared with different concentrations of borax, anti-litter and different treatment with urea. The growth of the same treatment for each selected three trees in full bloom flowering, the other three as a control. Before spraying, select a large branch in the selected tree and investigate the number of inflorescences, the number of flowers and the number of fruits after physiological drop-off. First, the effect of boron on improving the fruit set rate of apple
