摘要
为实现油菜优质高产,设置了不同的有机无机氮肥配施方案,以期为四川地区油稻轮作模式下合理的施肥制度提供理论依据。本试验于2020-2022年进行,以绵油309为供试材料,油菜季设置Y1~Y5(有机肥替代量分别为20%、30%、40%、50%和0%)共5个处理,具体分析产量及其构成因素、籽粒品质以及经济效益变化情况。结果表明,有机无机肥配施显著影响主序粒数、产量及其构成因素,且以Y2处理增产效应和经济效益最佳。配施有机肥可以提高绵油309的芥酸和硫甙含量,具有提高籽粒含油量的趋势,Y1、Y2和Y3处理均可提高籽粒亚麻酸和花生烯酸等有益成分含量。
In order to achieve high quality and high yield of rapeseed,different schemes of organic and inorganic nitrogen fertilizer were set up in this experiment for providing theoretical basis for reasonable fertilization system of oil-rice rotation mode in Sichuan area.In this study,Mianyou 309 was used as the test material from^(2)020 to 2022.Five treatments of Y1 to Y5(replacement amount of organic fertilizer was 20%,30%,40%,50%and 0%,respectively)were set up in rape season to analyze the changes of rape yield,yield components,grain quality and economic benefits.The results showed that,organic and inorganic fertilizer application had significant effects on the number of main inflorescence grains,yield and its components,and the increase effect and economic benefit of rapeseed were the best with Y2 treatment.The combined application of organic fertilizer could increase the contents of erucic acid and glucosinolates,which had a tendency to increase the oil content of Mianyou 309.The contents of beneficial component of the Y1,Y2 and Y3 treatments such as linolenic acid and arachidonic acid were increased.
