侧深施肥技术在单季晚稻上的应用效果

Effects of Side-deep Fertilization Technique on Single Cropping Late Rice

以单季晚稻甬优1540为材料,水稻专用配方肥为基础,搭配不同的基肥施用方式,研究了不同施肥方式对水稻产量和效益的影响。结果表明,与人工撒施基肥的处理相比,应用侧深施肥技术的处理,可减少基肥用量,加快水稻分蘖速度,增加有效穗数,可增产3.0%以上。

A field experiment was conducted to study the effects of different fertilization methods on yield and benefit of rice, using single cropping late rice Yongyou 1540 as material. The results showed that, compared with artificial fertilizer application method, the technique of side deep fertilization could reduce the amount of base fertilizer, accelerate the tillering speed of rice, increase the number of effective panicles and the yield of rice could be increased by more than 3%.
