不同栽培因子对甬优8号水稻生育期与产量的影响
Effect of Sowing Date,Basic Seeding,Nitrogen Fertilization and Water on the Growth Duration and Grain Yield of RiceYongyou 8
摘要
Abstract
In order to select the optimum cultivation combination,we conducted orthogonal experiments to hybrid japonica rice Yongyou 8 from different sowing date,basic seeding,nitrogen application rate and water. The results showed that the whole growth duration (y)was significantly influenced by sowing date(x)(F=82. 71﹥F0. 05),which had significant negative correlation(y= -0. 4x+149. 67(R=0. 9 986*)). Effective panicles were significantly influenced by basic seeding(F=52. 74﹥F0. 05. There was positive correlation between basic seeding and effective panicles,but negative correlation between grain filling and 1 000-grain weight. Both seeding date and nitrogen fertilization had remarkable influence on the yield of Yongyou 8. Meanwhile,planting density had greater effect on the yield. The study suggested that the optimum cultivation combination of Yongyou 8 was that sowing date was May 5 and planting densities were 5. 46 × 103/667 m2 . And then nitrogen application rate was 20 kg/667 m2 with suitable water on soil surface.关键词
