果乐对苹果梨生长发育和果形畸变的调控

The regulation of chemicals on Pyrus pyriforia (Burn) Nakai,cv. Pingguolis growth and development of fruit lopside

在苹果梨盛花期分别喷洒一定浓度的果乐 1号和 6号 ,改变授粉时的营养条件 ,促进受精作用 ,使种子和果实生长发育良好。实验结果表明 ,喷洒果乐提高了座果率和单果重 ,降低果形畸变 50 %左右 ,增加产量 2 0 %左右 ,同时也改善了果实品质 ,使含糖量有一定的提高。

Spraying certain concentration of Guole (No.1 and No.6) before flourish blossoming of Pyrus pyriforia (Burn) Nakai,cv. Pingguolis ,might alter nutrient factors of pollination;and facilitated the effect of its insemination;therefore subsequently promoted seed and fruit development obviously.The results indicate that Guole raises Pyrus pyriforia (Burn) Nakai,cv. Pingguoli s maintain rate of fruit and single fruits weight;reduces lopsided fruit by 50 percent;increases yield more about 20 percent;at the same time hightens fruits sugar content;and ultimately improves fruits quality.
