乌桕是本省三大木本油料之一。如何加速良种嫁接苗的繁育,以供大规模基地造林之用,是当前乌桕生产上急待解决的问题。这里介绍的“三当”快速繁育乌桕嫁接苗的方法,是我们通过试验找出来的。用这一方法能将原来需要两年才能育成的嫁接苗,缩短成为一年。因这一方法是当年播种、当年芽接,可以当年出圃,所以称为“三当”育苗。它有速成、提高土地利用率一倍,节约良种接穗3—4倍、节省育苗用工、节省成本40%以上等优点。现介绍如下。一、快速培育砧苗为寻求加速实生砧苗生长的方法,我们进行了冬播、春播、催芽春播和催芽春播覆盖塑料薄膜等试验。结果以催芽春播覆盖塑
Ukraine is one of the province’s three major woody oil. How to speed up breeding of grafted seedlings for large-scale afforestation purposes is an urgent solution to the current problem. Introduced here, “three when” rapid breeding method of grafted seedlings, we find out through the experiment. With this method can be the original need two years to grow into a grafted seedlings, shortened to one year. Because of this method is the year sowing, when budding then, you can out of nursery, so called “three when” nursery. It has quick, double the utilization of land, saving 3-4 times the elite seed scion, save seedling labor, cost savings of more than 40% and so on. Now introduced as follows. First, the rapid cultivation of anvil seedlings In order to seek ways to accelerate the growth of seedlings, we conducted winter sowing, spring sowing, spring sowing germination and germination spring sowing covered plastic film and other tests. The results of the germination spring cover plastic
