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/hm2,施用NPK复合肥300kg/hm2+尿素300 kg/hm2效果最好,施用缓释肥450 kg/hm2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.
Abstract
[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.
