建立果园营造防护林,可以防止风沙,减少折枝落果,保証果树的正常生长。过去我們营造果园防护林,只单純考虑防护,沒有注意多种利用。要尽量发揮防护林的作用,必須从果树生产的多方面着想。我們知道要提高果树单位面积产量,除了加强經营管理以外,提高果树授粉率,对增加結果量也是一个十分重要的措施。試驗証明,依靠蜜蜂授粉效果是最显著的。
The establishment of orchards to create shelterbelts, can prevent sand, reducing the broken branches and falling fruit, to ensure the normal growth of fruit trees. In the past we built orchards shelter, only consider the protection, did not pay attention to the use of a variety. In order to give full play to the role of shelterbelt, we must think in many aspects of fruit tree production. We know that to increase the yield per unit area of fruit trees, in addition to strengthening management, raising the rate of fruit tree pollination is also a very important measure for increasing the quantity of results. Experiments show that relying on bee pollination effect is the most significant.
