不同播期·种植密度和施肥量对玉油1号农艺性状及产量的影响
Effects of Different Sowing Date,Planting Density and Fertilizer Dosage on Agronomic Characters and Yield of Yuyou No.1
摘要
Abstract
[Objective] To explore the optimal sowing date,planting density and fertilizer dosage of high oil content double low rapeseed cultivar Yuyou No.1,to realize the combination of good breeding and high yield cultivation techniques,and to promote the application of Yuyou No.1 in Yunnan Province. [Method]Using three-factor and three-level orthogonal test,we researched the optimal sowing date,planting density and fertil-izer dosage of Yuyou No.1 in Yuxi City,and their effects on main agronomic traits and yield. [Result] The effects of three factors on yield from big to small were in the order of sowing date,urea dosage,planting density. Among them,only sowing date had significant impacts on yield. So-wing date showed significant impacts on growth period,effective pods per plant,grain number per pod and 1 000-grain weight; planting density had positive correlation with effective pods per plant;urea dosage had no significant impacts on growth period and urea dosage. [Conclusion] The optimal sowing date,planting density and fertilizer dosage for Yuyou 1 in middle elevation rapeseed planting area were October 15-October 20,18 ×104-21 ×104plants/hm2and 525 kg/hm2,respectively.关键词
