1催芽播种银杏种子一般只有70%左右的发芽率,直接播种往往缺苗断垅,降低土地利用率。催芽播种可提早播种时间,使苗木的根茎部位在高温季节到来时达到初步木质化,使其有较高的抵抗力,有利于增加苗木的保存率。催芽播种常用的方法是沙藏层积处理,沙藏时间为100...
A germination of ginkgo seeds generally only about 70% of the germination rate, direct seeding is often lack of seedlings, reducing land utilization. Germination sowing can sowing time earlier, so that the rhizome parts of seedlings in the hot season to reach the initial lignification, it has a higher resistance, help to increase the conservation rate of seedlings. Germination sowing commonly used method is sand reservoir stratification, sand reservoir time is 100 ...
