近年来,随着小麦生产不断发展和产量日趋提高,麦田地力普遍感到不足。丰产和缺肥的矛盾,日漸尖銳。因此,迅速提高麦田的肥力,就成为小麦生产的中心問題。提高地力的途径不外两方面:一是增加肥料,开辟肥源,实行“施肥养田”。二是合理輪作,安排茬口,实行“以田养田”。从全面提高产量出发,只有把“以田养田”和“施肥养田”結合起来,才是最合理想的措施。但是在目前普遍缺乏肥料的情况下,实行“以田养田”就成为提高地力的主要手段。
In recent years, with the continuous development of wheat production and increasing production, wheat field generally felt inadequate. The contradiction between high yield and lack of fertilizer has become increasingly acute. Therefore, rapidly increasing the fertility of wheat fields has become a central issue in wheat production. There are only two ways to improve soil fertility: First, increase fertilizers, open source of fertilizers, and implement “fertilizing fields”. Second, a reasonable rotation, arrangements stubble, the implementation of “to Tian Tian ”. From the overall increase in production, only the combination of “field cultivation” and “fertilizer cultivation” is the most reasonable measure. However, under the current general lack of fertilizer, the implementation of “cultivating the fields with fertility” has become the main means of improving fertility.
