摘要
采用6种不同施N水平,研究施N量对嘉糯1优6号产量的影响。结果表明：施纯N在0-200 kg/hm2内,随着施N量的增加,有效穗数、每穗粒数、理论产量、实际产量、移栽至抽穗期各阶段干物质积累都显著提高,而结实率和千粒重呈下降趋势,有的达显著水平;当施纯N提高至250 kg/hm2时,每穗粒数、结实率、千粒重、理论产量、实际产量、抽穗至成熟期干物质积累都呈下降趋势。可见,嘉糯1优6号最佳施N水平为200kg/hm2。
Taking hybrid glutinous rice Jianuo 1 you No.6 as material, using 6 different levels of nitrogen fertilizer application to study the relationship between yield and the amount of nitrogen fertilizer application,and the researched results as follows： with the increased of nitrogen fertilizer application ranged from 0 to 200 kg/hm2, productive panicle, spikelets per panicle, theory yield, actual yield, dry material accumulation from transplanting to heading are significantly improved, but seed setting rate and 1000-grain weight trends to declined, furthermore, some of the difference existed significantly; under the level of nitrogen fertilizer application for 250 kg /hm2, spikelets per panicle, seed setting rate, 1000-grain weight, theory yield, actual yield, dry material accumulation from heading to mature are declining, and most of the difference existed significantly. the best level of nitrogen fertilizer application for hybrid glutinous rice Jianuo 1 you No.6 is 200 kg/hm2.
