毛白杨是我国特有树种之一,它具有生长快、材质好、寿命长、用途广等优点,深受群众欢迎,但由于扦插育苗不易生根,不能大量繁殖,满足不了林业生产发展的需要。为了解决这个问题,我们遵照毛主席关于“在实践中不断地开辟认识真理的道路”的教导,于一九六六年开始培育,经过多年的育苗试验,不断总结经验教训,寻找毛白杨扦插育苗不易生根成活的主要原因,大胆试验,不断革新,采用高垄扦插育苗获得初步成功,成活率达80%。这方法的优点是:1.省工省事,简便易行,不受条件限
Populus tomentosa is one of the endemic tree species in our country. It has the advantages of fast growth, good material, long life and wide use. It is welcomed by the masses. However, it is not easy to multiply because of cutting propagation and seedling, which can not meet the needs of forestry production. In order to solve this problem, we follow Chairman Mao’s teachings of “constantly opening up the path of truthfulness in practice” and began to cultivate in 1966. After years of nursery trials, we constantly sum up experiences and lessons and find out the best practices for raising cutting seedlings of Populus tomentosa Not easy to root causes of survival, bold test, continuous innovation, using high ridge cuttings to obtain initial success, the survival rate of 80%. The advantages of this method are: 1. Saving and saving labor, easy and free from restrictions
