舒城县张母桥农技站高贤玉在实践中发现,有很多农户在晚稻施肥这一技术上很不科学,为争取高产,往往不根据具体情况,盲目加施氮磷肥,以期丰收。但如果长期过量施用某单一肥料,不仅会使土壤板结,还易使作物发生生理性病害和病虫的危害。因此应实施平衡施肥技术;增加钾肥和适量微肥的施用量,既能增加产量,又改善了土壤结构。具体方法如下:
Shu Xianxianqiao Agricultural Technology Station Gao Xiangyu found in practice, many farmers in the late rice fertilization technology is very unscientific, in order to strive for high yield, often not according to the specific circumstances, blindly add nitrogen and phosphorus fertilizer in order to harvest. However, long-term over-application of a single fertilizer will not only make soil compaction, but also make the crop susceptible to physiological diseases and pests. Therefore, balanced fertilization techniques should be implemented; increasing the amount of K fertilizer and appropriate amount of micro-fertilizer, both to increase production, but also to improve the soil structure. Specific methods are as follows:
