初、麦两熟是豫南初区普遍采用的一种轮作方式,常年约占水(禾刀)总面积的35—40%。这类(禾刀)田,长期以来存在的主要问题是肥料不足,(禾刀)麦产量偏低,特别是对水(禾刀)产量影响更大。为了增辟肥沅,以田养田,促进(禾刀)麦持续高产,1973年以来,我们进行了(禾刀)麦两熟插种绿肥试验。现将试验结果简报于后。一、(禾刀)麦两熟插种绿肥的方式和效果(禾刀)麦两熟插种绿肥的方式是“麦——肥——(禾刀)”。于小麦收割后插种绿肥,7月15日以前收割。根据粳(禾刀)较为耐寒的特点,把中籼
Early, wheat two ripening is a commonly used method of rotation in southern Henan early, perennial about water (Wo knife) the total area of 35-40%. The main problem of such fields is the lack of fertilizers, the low yield of wheat and the greater impact on the production of water. In order to increase fertile Yuan, Tian Tian, promote (Wo knife) wheat continued high yield, since 1973, we conducted (Wo knife) wheat two-cropping green manure experiment. Now the trial results briefed later. First, the (Wo knife) wheat two kinds of intercropping green manure and the effect (Wo knife) Intercropping wheat green manure way is “wheat - fat - (Wo knife).” Green wheat is planted after wheat harvest and harvested before July 15. According to japonica (Wo knife) more cold-resistant characteristics, the medium indica
