河西沿祁连山冷凉灌区发展小麦生产有优越的自然条件。近年来随着化肥投入量的增加,成本也提高,如何发挥化肥最佳效益,解决生产中存在增产不增收的问题,已成为当前的迫切任务。为了摸索该类地区小麦高产的最佳化肥用量标准,降低生产成本、增加经济效益的途径,我们进行了化肥最佳用量经济效益的试验研究。 Hexi area along the Qilian Mountains irrigation development of wheat production has superior natural conditions. In recent years, with the increase of input amount of chemical fertilizers, the cost has also increased. How to give full play to the best benefit of chemical fertilizers and how to solve the problem of increasing yield without increasing income in production has become an urgent task at present. In order to explore the best high-yield wheat in this region the best fertilizer dosage standards, reduce production costs and increase economic efficiency, we conducted a pilot study on the optimal dosage of fertilizer economic benefits.
