香椿是一种木本保健蔬菜。椿树易管易种,繁殖力强,对土质要求不严重,我国南北均可种植。要获得香椿高产,关键要抓好种子处理和矮化密植二项措施。一、种子处理:一是去掉外壳。香椿种子内部是棉质状载体,外部是呈瓣的硬壳,中部是种粒,每枚带壳种有20粒左右。播种前先将外壳去掉,取出籽粒。方法是:将带壳种置于阳光下翻晒,外壳会自然张开,此时可抖出种粒。二是进行磁化。种粒经机械磁化后可提高发芽率。若没有磁化机械,可自制磁化 Toon is a woody health care vegetable. Chun-tree easy-to-tube easy to grow, strong propagation, soil requirements are not serious, our country can be planted both north and south. To get high-yield Toon, the key should grasp the seed treatment and dwarf and dense planting two measures. First, the seed treatment: First, remove the shell. Toon seed is a cotton-like carrier inside, the outer is a petal hard shell, the middle is a seed, each with about 20 shell species. Remove the shell before sowing, remove the grain. The method is: the shelled species placed in the sun under the sun, the shell will naturally open, then shake out the seeds. The second is to magnetize. Seed grain by mechanical magnetization can improve the germination rate. If there is no magnetizing machine, self-made magnetization
