香椿要获得高产,最关键的是要抓好种子处理和矮化密植两个方面。 (一)种子处理 ①去掉外壳:香椿种球内层是棉质状载体,外部是呈瓣的硬壳,中层才是种粒。每枚带壳种有20粒左右。播种时应将外壳去掉,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,即可抖出种粒。②磁化处理:若经机械磁化后再贮放或播种,可提高发芽率。若没有磁化的专用机械,也可自制磁化水浸泡种粒再播种,仍有良好效果。方法是:将烧开后的沸水从磁铁上慢慢流过,或将磁铁置于水中,烧开5分
Toon high yield, the key is to grasp the two aspects of seed treatment and dwarf density. (A) seed treatment ① remove the shell: Toon inner ball is a cotton-like carrier, the outer is the petal hard shell, the middle is the seed. Each shell species about 20. The shell should be removed when sowing, remove the grain. The method is: the shelled species placed in the sun under the sun, the shell will naturally open, you can shake out the seeds. ② magnetization: If the mechanical magnetization or storage or sowing, can increase the germination rate. If there is no magnetized special machinery, but also self-made magnetized water soaking seeds and then sowing, there are still good results. Method is: boil the boiling water from the magnet slowly flowing, or the magnet placed in water, boil 5 minutes
