核桃是一种珍贵的乾果,营养价值很高,而木材结构细致,有弹性,不翘不裂,是优质良材。 为了促进核桃快速成林,提早结实,我们曾在本县张圩林场进行了核桃催芽直播造林试验,取得了显著效果,经催芽直播造林的核桃、5—6年就开始结实,10—12年就可进入盛果期。现将催芽直播造林技术介绍如下: 一、方法 1.选种:选粒大,饱满,薄壳,无病虫害的优良核桃品种。 2.催芽:2月中下旬或3月上旬,用清水浸种4—5天(每天换一次清水),捞出后把种子横放在温床中,然后上面用塑料布覆盖。覆土3厘米左右,经催芽处理 Walnut is a precious dried fruit, high nutritional value, and detailed structure of wood, flexible, not Alice not crack, is a good quality material. In order to promote rapid rapid succession of walnut forest, early and strong, we have in the county Zhang Wei farm walnut germination direct seeding afforestation experiment, and achieved remarkable results, the germination of live walnut direct seeding, 5-6 years began to strong, 10-12 years You can enter the fruitful period. Will now germination broadcast afforestation technology are as follows: First, the method 1. Selection: Selection of large, full, thin shell, no pests and diseases of the fine walnut varieties. 2. Germination: late February or early March, soaked with water 4-5 days (a change of water every day), remove the seed placed on a horizontal bed, and then covered with plastic sheeting.
