不同种植方式对再生稻产量和品质的影响
Effect of different planting methods on yield and quality of ratooning rice
摘要
Abstract
The rice variety 'Nongxiang32' was used as material and planted by seedling throwing(STR), artificial transplanting(ATR) and direct seeding (DSR), to study the effects of different planting patterns on the yield, yield components and quality of main rice and ratooning rice. Results showed that: the yield of the main rice was the highest by artificial transplanting (ATR), because of the high grain number per panicle, seed setting rate and 1000 grain weight; the yield of the ratooning rice was the highest by seedling throwing(STR); the yields by STR(11.42 t/hm2) and ATR (11.33 t/hm2) were 16.2% and 15.1% higher than the yield by DSR (9.84 t/hm2) in two seasons; the milling quality of the main rice was better thanthat of the ratooning rice; appearance quality such as chalky grain rate, chalkiness, amylose content, gel consistency, gelatinization temperature, cooking quality and nutritional quality of ratooning rice were better than those of main rice. In summary, the yield of 2 seasons by STR was slight higher than that by ATR, and had a good rice quality. So STR is a good planting method and should be widely popularized.关键词
