摘要
为提高水稻品种绥粳15的产量及品质,对水稻品种绥粳15在水直播时进行了不同氮肥施肥水平和施肥比例的研究。结果表明:绥粳15的最适施氮总量为180kg·hm^(-2),施氮比例底肥∶蘖肥∶穗肥为4∶3∶3时,实现了高产优质的栽培目标。
In order to improve the yield and quality of the rice new cultivar Suijing 15,different nitrogen levels and proportion of fertilizer by water direct-seeding cultivation were studied.The results showed that compared with the other treatments,total nitrogen was 180kg·hm-2,the proportion of base fertilizer∶tiller fertilizer∶spike fertilizer was 4∶3∶3,which was the best composite mode.
