影响祝光苹果产量的主要原因是落花落果严重。在盛花期通过枝干环剥或喷1000 ppm的增产素1号、0.5％硼砂+0.5％尿素、0.5％硼砂等处理,均可提高座果率。其中以环剥效果最好,比对照座果率可提高80％;增产素1号可提62.36％;二者与对照之间均达极显著性差异。其次,硼砂十尿素比对照提高座果率42.11％;硼砂可提高33.54％。
The main reason affecting the output of ZhuGuang apple is a serious fall. In the flowering period through the branches girdling or spraying 1000 ppm of ZS-1, 0.5% borax + 0.5% urea, 0.5% borax and other treatments, can improve fruit set rate. Among them, the stripping effect was the best, which could increase 80% compared with the control; the fruit yield of ZS-1 could be increased by 62.36%; both had significant difference with the control. Secondly, borax ten urea than the control to improve the fruit rate of 42.11%; borax can increase 33.54%.
