我们在1977年冬前气温偏高,雨水较足,麦苗发生旺长的情况下,摸索试验了小麦过垄断根的控制办法,当时取得了显著的控制效果,为小麦增产创造了条件。近年来随着生产条件的改变,小麦施肥量加大,为了解决小麦在冬前培育壮苗中发生旺长,分蘖过多消耗营养和后期倒伏的问题,我们对过垄断根继续进行了试验研究工作。经过三年来的实践和观察,小麦过垄断根的时间,是在播种后一个半月左右,即在11月中、下旬,或12月上旬日平均气温8℃至18℃,苗
In the winter of 1977, when the temperature was high, the rain was full, and the wheat seedlings flourished, we explored and tested the control method of wheat over monopoly roots. At that time, we achieved remarkable control effects and created the conditions for increasing wheat yield. In recent years, with the change of production conditions, the amount of wheat fertilization increases. In order to solve the problem of flourishing wheat, excessive nutrition of tillering and late lodging of wheat in winter, we conducted an experimental study on over-monopolization roots jobs. After three years of practice and observation, wheat monopolize the root of the time is about one and a half months after sowing, that is, in mid-November, or early December the average daily temperature of 8 ℃ to 18 ℃, Miao
