氮肥用量对机插优质粳稻武运粳27号产量和品质的影响
Effects of Nitrogen Application Rate on Grain Yield and Quality of Mechanical Transplant-ing Japonica Rice Wuyunjing 27
摘要
Abstract
The effects of nitrogen application rate on grain yield and quality were investigated using fine quality japonica rice cultivar Wuyunjing 27 under mechanical transplanting cultivation pattern. The results showed that the effective panicles, the number of grains per panicle, and the grain yield increased first and then decreased with the increase of nitrogen application rate, while the seed setting rate and 1000-grain weight decreased. The brown rice rate, milled rice rate and head rice rate increased first and then decreased with the increase of nitrogen application rate, the grain protein content increased, while the amylase content, taste value, peak viscosity, hot viscosity, cool viscosity of rice starch decreased. Considering both the grain yield and quality, the 225~300 kg/hm2 of nitrogen fertilizer rate is suitable for Wuyunjing 27.关键词
