一、种子处理与播种:草木栖种皮非常坚硬,不进行碾磨处理,水分不易渗入,常常在土壤中保存三——四年,到四五年之久,这样不仅降低了当年应有的苗数,而且会造成以后长时期中断续出土,反变成对栽培作物有害的杂草。处理的方法,根据我们试验,不碾磨的种籽出苗率仅36%左右,在石碾上碾磨400圈的苗率达95%以上。只碾掉荚果的网纹壳,是不全引起什么作用的,这一点是千万不能忽视的。
First, seed treatment and seeding: Habitat species of grass vegetation hard, not grinding, moisture is not easy to infiltrate, often stored in the soil three to four years to four or five years, so not only reduced the year should be Seedling number, but will result in a long period of intermittent unearthed, the anti-turned into a weed on the crops harmful to crops. According to our test, the germination rate of the unmilled seeds is only about 36%, and the rate of seedlings milled over 400 cycles on the stone mill is more than 95%. Only grinds off the reticulated shell of the pod, what does it cause incompletely? This point must not be neglected.
