苹果和梨等果树进入盛果期后往往出现大小年现象。尤其在雨水不调年份更为明显,如遇小年花芽量太少就必须进行保花保果以提高坐果率,其措施如下。 1.花期放蜂 可在全园分几个小区放蜂,每小区放10箱蜜蜂可供500株果树传粉。如有条件可事先采些花粉放到蜂箱出口处,使蜜蜂带粉采蜜。但在风速过大,低温多雨天则效果较差。切忌花期喷药。
Apple and pear and other fruit trees often appear after the full-year fruit size phenomenon. Especially in the rainy season is more obvious, in case of small annual flower buds too small flowers and fruit must be carried out to improve fruit setting rate, the measures are as follows. 1 flowering bee can be put in a few quarters of the park put bees, put 10 boxes per area for 500 fruit trees pollination. If available, pollen can be collected beforehand at the exit of the beehive to make the honeybee take the powder to collect the honey. However, the wind speed is too large, low temperature and rainy days are less effective. Avoid spraying flowers.
