不同品种缓(控)释肥对水稻产量与效益的影响

Effects of Slow(Controlled)Release Fertilizers on Rice Yield and Benefit

缓(控)释肥作为一种根据作物养分需求缓慢释放的新型肥料,对水稻生产有省工节本增效作用。本次试验设6个处理,分别为“汉枫”缓释掺混肥、“贸昇”缓释掺混肥、“住商”缓释掺混肥、中东“绿聚能”缓释掺混肥、“心连心”控释肥、中东复合肥(CK),采用在相同施氮量18 kg/667 m^(2)条件下,比较5种缓(控)释肥施用对南粳9108的产量及效益影响。结果表明,“住商”缓释掺混肥、“贸昇”缓释掺混肥、“汉枫”缓释掺混肥施用效果较好,南粳9108产量分别达680.73、674.89、663.65 kg/667 m^(2),比CK分别增产17.10%、16.09%、14.16%,比CK分别增收148.17、120.33、92.71元/667 m^(2)。

Slow(controlled)release fertilizer,as a new type of fertilizer that is slowly released according to crop nutrient requirements,has a cost saving and efficiency enhancing effect on rice production.Six treatments were set up in this experiment,including slow(controlled)release fertilizers of Hanfeng,Maosen,Zhushang,LvJuneng and Xinlianxin and Zhongdong compound fertilizer(CK).Under the same nitrogen application rate of 18 kg/667 m^(2),the effects of 5 types of slow(controlled)release fertilizers on yield and benefit of Nangeng 9108 were compared.The results showed that among them,the slow(controlled)release fertilizers of Zhushang,Maosheng,and Hanfeng had better application effects,and the yield of Nangeng 9108 were 680.73,674.89 and 663.65 kg/667 m^(2),respectively,increasing by 17.10%,16.09%,and 14.16%compared to CK,and increasing income by 148.17,120.33,and 92.71 yuan/667 m^(2) compared to CK.
