| 摘 要： | 为提高9108和皖垦糯2号生产区机插水稻生产效率,实现其优质与高产协调发展,用田间试验,分析氮肥运筹与硅肥配施对南粳9108和皖垦糯2号产量和品质的影响。结果表明,以40%基肥、30%分蘖肥和30%穗肥的氮肥运筹配施硅肥450 kg/hm2为最佳,且与常规氮肥运筹相比,显著提高了每穗总粒数、结实率、整精米率。

Effects of Nitrogen Fertilizer Management and Silicon Fertilizer Combined Application on Rice Yield and Quality1 |
| |
| Abstract: | SIn order to improve the production efficiency of machine-transplanted rice in the production areas of 9108 and Wankennuo No. 2 and realize the coordinated development of high quality and high yield, field experiments were used to analyze the effects of nitrogen fertilizer management and silicon fertilizer on the yield and quality of Nanjing 9108 and Wankennuo 2 Impact. The results showed that the nitrogen application of 40% basal fertilizer, 30% tiller fertilizer and 30% panicle fertilizer combined with silicon fertilizer 450 kg/hm2 was the best, and compared with conventional nitrogen fertilizer management, this treatment significantly increased the total number of grains per panicle. , Seed setting rate, whole rice rate . |
