侧深施肥技术对机插早稻产量的影响

Effects of Side Deep Fertilization Technology on Yield of Machine Transplanted Early Rice

以高产水稻品种中早39为材料,研究了机插过程中机械化精量侧深施基肥方式对水稻产量的影响。结果表明,与农户传统撒施基肥方法相比,通过机械化精量侧深施入基肥的处理,可减少基肥使用量,提高肥效,加快分蘖速度,增加单位面积有效穗数,水稻产量增加11.0%以上。

An experiment was conducted to study the effects of different base-manure fertilization methods on yield,using indica rice Zhongzao 39 as material.Compared with traditional base-manure fertilization method,the side deep base-manure fertilizing method with machine transplanting could reduce the quantity of base-manure fertilizer,enhance effectiveness of fertilizer,speed up the growth of tillers,increase the number of effective panicles,and the yield was increased by 11.31%.
