摘要
为探索高桩机收再生稻最佳芽苗肥施用量,以宜优673为材料,设计不同芽苗肥施用量组合试验。结果表明,收割前施促芽肥能够提高低节位芽的萌发力,随着促芽肥施用量的提高,机收碾压区和未碾压区丛有效穗数均有所提高,而穗总粒数、结实率、千粒重各处理间相差不大。其中每667m2促芽肥施15 kg尿素、促苗肥施10 kg尿素、齐苗肥施5 kg尿素处理碾压区和未碾压区的有效穗最高,再生季产量也最高。重施促芽肥的处理比不施或少施的处理,产量差异达到了极显著水平。
To explore the high pile their ratooning rice best bud seedling applying fat content, this paper appropriate Yiyou 673 as material, and designed different bud seedling fertilizer seems combination test. Results show that before the harvest to promote bud fertilizer can improve the low section a bud germination force, with the improvement of applying stimulating fat content, receive a crushing zone and rolling zone plexus effective panicle number increased, and the total number of grains per ear, seed setting rate and grain were similar between the groups. Each 667m2 stimulating 15 kg urea fertilizer, promote seedling 10 kg urea fertilizer, good seedling emergence fat 5kg urea treatment effective ear top roller compacted zone and rolling zone, reproductive season production was the highest. Return to stimulating the processing of fat than without or less processing, production difference reached significant level.
