高蛋白大豆新品种吉育259高产栽培技术研究与示范

Research and Demonstration on High Yield Cultivation Technology of A High Protein Soybean Variety Jiyu 259

为了明确适合吉林省早熟区生产上主推的大豆品种吉育259的高产优质综合栽培技术,促进良种良法配套提高生产技术水平,本研究设置4个种植密度(22万,25万,28万和30万株·hm^(-2))、3个品牌种衣剂处理(锐胜、豆粒特和多福克)、3水平施肥量(200,300和400 kg·hm^(-2))和4种化控处理(多效唑、烯效唑、矮壮素和缩节胺),通过比较该品种的农艺性状、产量及品质表现,筛选出最优栽培技术措施,并进行大面积展示与示范。结果表明,吉育259最适种植密度为25万株·hm^(-2),配套使用先正达锐胜种衣剂、大豆复合肥施用量为300 kg·hm^(-2)、始花期喷施烯效唑化控调节剂,增产效果显著。应用优化的配套栽培技术对吉育259进行2年4点的示范,取得了高产优质的较好成果。

In this study,Jiyu 259,mainly promoted in the early maturing area of Jilin Province,was used as the experimental material to evaluate its performance of agronomic characters,yield and quality,and further clarify the comprehensive cultivation technical conditio ns of high yield and quality,so as to improve the production technical level and achieve the effect of matching varieties and methods.4 planting densities(220000,250000,280000 and 300000 plants·ha^(-1)),3 seed coating agents treatments(Ruisheng,Doulite,Duofuke),3 fertilizer application rates(200,300,400 kg·ha^(-1)),and 4 chemical control treatments(paclobutrazole,unenobutrazole,pyronectin and dendroamine)were set up in the experiment.Through comparison,the optimal cultivation techniques were selected out,and then to carry out large area display and demonstration.The results showed that the optimum planting density of Jiyu 259 was 250000 plants·ha^(-1).Use Syngenta Ruisheng seed coating agent,compound fertilizer application rate of 300 kg·ha^(-1),the first flowering period sprayed with enazole control regulator,could achieve a significant effect of yield increase.By the optimized cultivation technology,the demonstration of Jiyu 259 at 4 areas in 2 years obtained good results.
