栗树在生产上突出存在的问题是树冠外移、大小年、雄花多、树势弱等。近年,我们试验用短截、摘心的办法解决这一问题,结果证明,增产效果显著且稳产。现简介如下: 一、短截1.时间和方法:3月下旬至4月上旬(树液流动后至芽萌动后)进行。短截分轻截、中截和重截三种处理。重短截可以防止树冠外移并能改变树体结构;轻截缓放能保证产量的提高。板栗一般是大的饱满芽抽生结果枝和壮枝。短截时要看品种、枝芽,看措施的配合,
Chestnut prominent in the production of the problem is the relocation of the crown, the size of the year, more male flowers, tree weak and so on. In recent years, we experimented with a short cut and a topping method to solve this problem. The result proves that the yield increase is remarkable and stable. Now briefings are as follows: First, the stub 1. Time and method: late March to early April (after the flow of sap to bud sprouting). Short cut light cut, cut in and cut three kinds of processing. Heavy short cut can prevent crown migration and can change the structure of the tree; light cut slow release can ensure the yield increase. Chestnut is usually a big plump bud full of strong branches and branches. Short cut depends on species, buds, see the cooperation of measures,
