板栗又叫大栗,是我国特产的重要干果,主要的木本粮食树种之一。栗子果实含淀粉60％左右,糖分10—20％,蛋白质5—10％,以及多种维生紊和少量脂肪。因此,栗子不仅可以代粮,备战备荒,也是一种营养丰富的副食品。板栗又是果材兼用树种,木材较坚实,可支援国家社会主义建设需要。栗蒲、树皮含有大量丹宁,是提炼烤胶的重要原料。此外,栗耐瘠薄,适应性强,生长强健,是保持水土,改造自然,绿化环境的优良树种。因此,深受广大群众欢迎。 板栗的繁殖,有实生繁殖和嫁接繁殖之分。用实生苗繁殖,后代变异大,往往得不到预期的效果,而且栗子小,产量低,因此,多用嫁接繁殖。嫁接繁殖不仅能保持原优良品种的特性,而且能提早结果。过去不少地方,采用野生茅栗移栽后嫁接或就地嫁接,随着“农业学大寨”运动的深入发展,为了多快好省地发展成片栗园、保证栗园整齐,现在多提倡育苗嫁接繁殖。这种繁殖方法是: Chestnut, also known as chestnut, is an important dried fruit of our specialty, one of the main woody food tree species. Chestnut fruit starch contains about 60%, 10-20% sugar, protein 5-10%, and a variety of vitamin and a small amount of fat turbin. Therefore, chestnuts can not only substitute for food, preparing for wasteland, but also a nutritious non-staple food. Chestnut is also a species of fruit trees, timber is solid, can support the needs of national socialist construction. Li Po, the bark contains a large number of tannins, baking glue is an important raw material. In addition, chestnut barren, adaptable, strong growth, is to maintain soil and water, transform nature, greening the fine tree species. Therefore, welcomed by the masses. Chestnut breeding, there is a real breeding and grafting breeding points. With seedling breeding, offspring variation, often do not get the desired effect, and chestnuts small, low yield, therefore, multiply and multiply. Grafting breeding not only to maintain the characteristics of the original fine varieties, but also to early results. In the past many places, the wild MaoZhu was grafted or grafted in situ after transplanting. With the deepening development of the movement of “learning from agriculture in Dazhai”, in order to develop into a piece of chestnut garden more quickly and economically, Breeding seedling breeding. This breeding method is:
