栗树是优良的木本粮食树种。栗子又是我国传统的出口物资之一。栗树适应性较强,寿命长,可一次栽植多年收益,对落实毛主席关于“备战、备荒、为人民”的伟大指示具有重大意义。我国北方栗子产区为了防止因长期采用种子繁殖,造成品种混杂,产量不高的现象,实行选择优良品种嫁接繁殖的方法,获得栗树高产稳产。嫁接繁殖有很多好处:1.提早结果,早期丰产;2.能保持母树的优良特性,促进粟树良种化;3.可以改造劣树为优树,变低产为高产;4.嫁接的栗树,树体较小,便于管理,可以密植,提高单位面积产量。
Chestnut tree is an excellent woody food tree species. Chestnut is one of China’s traditional export materials. The adaptability and long life of the chestnut tree can be planted for many years at a time. It is of great significance for the implementation of Chairman Mao’s great instructions on “preparing for war, preparing for famine and for the people.” In order to prevent the phenomenon of mixed species and low yield due to the long-term adoption of seed multiplication, the chestnut producing areas in northern China implemented the method of grafting and breeding fine varieties to obtain high and stable yield of chestnut trees. Grafting breeding has many benefits: 1. Early results, early high yield; 2. To maintain the excellent characteristics of the mother tree to promote poplar varieties; 3. Can be transformed inferior trees as superior trees, low yield is high yield; 4. Grafted chestnut trees , Tree smaller, easy to manage, close planting, improve yield per unit area.
