翠康苗壮叶面肥在水稻上的应用效果研究

Effects of Applying Cuikang Foliar Fertilizer to Rice

2010年在湖南省宁乡县青华铺乡八家湾村的一季稻和双季晚稻上进行了翠康苗壮叶面肥的田间应用试验。结果表明:同对照相比,不同时期喷施翠康苗壮叶面肥均能提高实粒数和结实率,一季稻最高提高幅度分别为11.5%和12.4%,晚稻最高提高幅度分别为9.9%和16.1%;在破口抽穗前喷施翠康苗壮叶面肥,一季稻增产8.5%,晚稻增产19.3%。在本试验条件下,喷施翠康苗壮叶面肥对水稻结实率和稻谷产量具有积极的影响。

In order to provide the scientific basis for application and promotion of Cuikang foliar fertilizer in major rice producing areas of the middle-lower Yangtze River Basin, the field application trials were conducted to the single cropping rice and double cropping late rice in Bajiawan village, Qinghuapu town, Ningxiang County, Hunan province in 2010. The results showed that in comparison with the control, spraying Cuikang foliar fertilizer at different period all can improve spikelet number and seed-set rate, the highest increase range of them in single cropping rice were 11.5% and 12.4% respectively, and the highest increase range of them in late rice were 9.9% and 16.1% respectively; spraying Cuikang foliar fertilizer to rice before heading stage, the yield of single cropping rice increased by 8.5% and the yield of late rice increased by 19.3%. With the experimental conditions, spraying Cuikang foliar fertilizer can improve the seed-set rate and increase the grain yield.
