[目的]研究赤杂29高产栽培技术,为该品种推广提供配套栽培技术服务。[方法]研究不同播期、密度、肥料对赤杂29千粒重和产量的影响。[结果]赤杂29的适宜栽培模式为5月中、下旬播种,留苗密度为11.25万~12.00万株/hm~2,施用NPK复合肥300kg/hm~2+尿素300 kg/hm~2效果最好,施用缓释肥450 kg/hm~2效果最好。[结论]适宜的播期、密度、肥料与适当的栽培管理措施相结合,能够增加品种产量。
[Objective] The research aimed to study the high-yielding cultivation techniques of Qa-29 and provide the technical support services for its promotion. [Method] The effects of different sowing date, density and fertilizers on 29 thousand kernel weight and yield were investigated. [Result] The suitable cultivation mode of Ch’a 29 was sowing in the middle and late May, the density of seedlings was 112,500-120,000 / hm ~ 2, the application of NPK compound fertilizer was 300kg / hm ~ 2 + urea 300 kg / hm ~ 2 The best effect, the application of slow-release fertilizer 450 kg / hm ~ 2 the best. [Conclusion] The suitable sowing date, density and fertilizer combined with proper cultivation and management measures could increase the yield of varieties.
