施用化肥对提高水稻产量及发挥新品种的潜力方面具有无可替代的作用,但在当前水稻栽培中,化肥应用普遍存在施用过量且施用时期不合理等问题,一方面增加了水稻生产成本,另一方面造成水稻贪青晚熟、抗病虫害能力差及环境污染,因此,如何正确使用化肥,提高肥料利用率,减少不合理投入,实现水稻高产高效节本生产,是当前需要迫切解决的现实问题。本文以新疆墨玉县加汗巴格乡水稻生产为例,通过调查稻田化肥施用及土壤肥力状况,提
The application of fertilizers has an irreplaceable effect on increasing the yield of rice and the potential of new varieties. However, in the current rice cultivation, there is a widespread problem of excessive application of fertilizers and unreasonable application period. On the one hand, rice production costs are increased, and on the other hand, On the one hand, it causes the rice to be late blooming and late blooming, its pest-resistance and environmental pollution are poor. Therefore, how to correctly use chemical fertilizers, increase fertilizer use efficiency, reduce unreasonable inputs, and realize high production and high efficiency and cost-saving production of rice are realistic problems that need to be urgently solved. This paper takes rice production in Jiahanbagh Township, Moyu County, Xinjiang as an example. By investigating the application of fertilizers and soil fertility in paddy fields,
