处于旱塬上的春播作物耕地,在漫长、少雨、风大的冬闲期间,有60％多的水分被蒸发损失掉。而且越接近地表损失越多,加之春季少雨,常常影响春播促苗,难以实现高产、稳产。 我们经过十多年的试验、研究,在收获秋作物过后,立即应用秸秆还同将所有秸秆打碎,覆盖于地面;或者 In the dry land of spring planting cropland, in the long, dry, windy winter leisure, more than 60% of the water is evaporated and lost. And the closer to the loss of surface more, with less rain in spring, often affect the spring sowing seedlings, it is difficult to achieve high yield and stable yield. After more than a decade of experiments and studies, we immediately stalwarted the application of stalks and covered all the stalks on the ground after harvesting autumn crops; or
