摘　　要：[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 ] High-yield cultivation techniques of Chiza No. 29 were studied for providing a set of cultivation technique service for the new product promotion. [ Method] Effects of different sowing date, density, fertilizer on 1 000-grain weight and yield of Chiza No. 29 were studied. [ Result] The suitable cultivation mode for Chiza No. 29 was that sowing in mid to late May, seedling density was 112 500 to 120 000 plants/hm2, using the NPK compound fertilizer 300 kg/hm2 ＋ urea 300 kg/hm2, slow-release fertilizer 450 kg/hm2, which achieved best effect. [ Conclusion ] The suitable sowing date, density, fertilizer combined with proper cultivation management measures can increase yield.
