我们在一块播种偏早、长势偏旺的麦田,摸索试验了“过垅断根”的控制办法。具体做法是:用锄横锄麦垅,将麦苗全部锄掉,深达2寸左右,切断下层须根,然后在原地带土顺垅放下,接着镇压和看墒浇水。由于采取过垅断根、镇压、伤叶,抑制了地上部分的生长,促进根系发育,使旺苗转化为矮壮苗。根观察,过垅断根7天后,就长出2—3条新的次生根,以后又连续长出7—8条粗壮的次生根。并且由于
In a crop of prematurely planted wheat fields that weakened, we explored and tested the control method of “over-cutting and root-cutting.” The specific approach is: Hoe hoe with wheat hoe, hoe all the wheat hoe off, up to 2 inches deep, cut off the lower fibrous roots, and then in the original zone of soil Shun down, then repression and see water moisture. As a result of a broken root, repression, injury leaves, inhibiting the growth of the aboveground and promote root development, Wang seedlings into short sturdy seedlings. According to the observation of the roots, 2-3 new secondary roots were grown after 7 days of abortion, and 7-8 thick secondary roots were continuously grown thereafter. And thanks
