施氮量对江苏沿海地区中熟中粳稻品种产量及品质的影响
Effects of Different Nitrogen Application Rates on Yield and Quality of Mid-ripe and Medium Geng Rice Varieties in Coastal Areas of Jiangsu Province
摘要
Abstract
In order to determine the effects of nitrogen fertilizer application on yield and quality of mid-ripening and medium geng rice in coastal areas of Jiangsu Province,Nangeng 5718 and Yandao 8269 were used as experimental materials,and field experiments were conducted under two treatments:no nitrogen fertilizer (N0) and 20 kg/667 m2 (N20) equivalent nitrogen application. The differences of yield,composition factors,cooking and eating quality of middle-ripe geng rice varieties under two nitrogen application conditions were studied by comparison and analysis. The results showed that after applying 20 kg/667 m2 of pure nitrogen,the number of peak seedlings,effective panicle number,thousand-grain weight and yield of Nangeng 5718 increased by 63.27%,62.94%,7.55% and 81.96%,respectively. Yandao 8269 increased by 62.23%,9.94%,5.80% and 79.89%,respectively. The eating quality of two varieties decreased by 8.89% and 4.12%,respectively. The milled rice rate was increased by 2.00% and 1.59%,respectively. The chalkiness and chalkiness grain rate decreased by 16.99%,10.13% and 23.42%,7.7%,respectively. Protein content was significantly increased by 16.67% and 9.59%,respectively. Therefore,pure nitrogen application of 20 kg/667 m2 can improve the yield of medium-ripe and medium geng rice,reduce the cooking and eating quality of rice,and improve the nutritional quality,processing quality and appearance quality of rice in the coastal areas of Jiangsu Province.关键词
