农业生产发展的经验证明,在一定的产量范围内,作物的产量随着施肥量的增加而增加,产量越高,需肥量也就越大。而我区目前仅以少量农家肥为“主体”的施肥水平是远远不能满足农业生产发展的需要。所以,必须重视化肥的投入,走以无机促有机,无机有机相结合的途径。必须打破长期处于封闭状态,使传统农业生产方式向现代农业 The experience of the development of agricultural production proves that within a certain range of output, the crop yield increases with the increase of the amount of fertilizer, the higher the yield, the greater the need of fertilizer. At present, the fertilization level of our country with only a small amount of farmyard manure as the “main body” is far from meeting the needs of the development of agricultural production. Therefore, we must attach importance to the input of fertilizers, take inorganic to promote organic, inorganic organic combination of ways. We must break the long-term closed state and bring the traditional agricultural production mode to modern agriculture
