给果树授粉是提高产量和质量的有效措施。实践中发现液体花粉喷射授粉法比果树自然授粉效果更好。与人工点授法比较,也具有省工、快速、高效(一般花液授粉能提高20％产量)等优点。果树花液授粉的具体方法如下。 1.适时采摘花蕾选择树干粗大、果实品质好、孕蕾茂盛的成年果树。在开花前2～3天,于晴天用干净瓷盘采集适量含苞待放的花蕾,带回室内摊开。采摘花蕾时间不能提前,也不能推后。
Pollinating fruit trees is an effective measure to increase yield and quality. In practice it has been found that liquid pollination pollination is more effective than natural fruit pollination. Compared with the artificial point teaching, but also has the advantages of labor-saving, rapid and efficient (usually flower pollination can increase 20% yield) and so on. Fruit flower pollination specific methods are as follows. 1. Timely picking buds choose thick stems, fruit quality, pregnant bud lush adult fruit trees. 2 to 3 days before flowering, in the sunny day with a clean collection of buds buds to be put back into the room spread out. Picking bud time can not be advanced, can not be pushed back.
