The effect of grass-crop rotation on crop yield increase

草田轮作对粮食作物的增产效应

Grass and crop rotation could increase the quantity of soil microorganism, intensify its activation, improve soil enzyme activity, enhance biological activity of soil and establish better soil environment condition.

草田轮作可以增加土壤微生物的数量，增强微生物的总体活性，也可以增加土壤的酶活性，进而提高土壤的生物活性，改善土壤的环境条件。

The result indicated that grass and crop rotation improves aperture condition of soil, to improve the condition of much air draft and drought and sand, because of abstract ability of keeping water on the chernozem of bad water erosion and wind erosion.

结果表明：在水蚀和风蚀严重的岗平地黑土上实行草田轮作，有利于改善土壤的孔隙状况，从而改善岗平地黑土的通气有余、持水不足、易于干旱和沙化的状况。

The undisturbed soil of the saline-alkaline grassland had the characteristics of hard soil, poor permeability, weak preserving water capacity, and the inhibition for the growth of the grass and the crop, so the produced potentiality of the crop did not adequately play.

盐碱化草原的原状土土壤坚硬而密实，土壤通透性差，涵养水分能力弱，对牧草和作物的生长发育具有抑制作用，作物的产出潜能也不能得到充分发挥。
