摘要
为探究有机无机氮配施对高芥酸油菜产量及品质的影响,本试验研究了6个不同处理(纯施有机肥、纯施无机肥、20%、30%、40%、50%有机肥替代量)对高芥酸工业型油菜(绵油309)产量、品质、土壤养分及经济效益的影响,以期为高芥酸工业型油菜的高产、提质、增效生产提供理论依据.结果表明:与单施化肥相比,一定比例有机无机氮配施可以显著提升油菜产量,30%有机氮配施处理产量最高,达3501.63 kg/hm2,较纯施有机肥显著增产24.84%,较纯施无机肥显著增产23.47%;有机无机氮配施促进油菜主序和分枝的生长发育.30%有机氮肥替代处理下在不影响芥酸含量的同时增加含油量,进而达到显著增加单位面积芥酸和食用油脂产量的目的;还能够提高土壤氮储量,从而使土壤维持较高肥力水平,实现油菜的减肥增效,以获得更高的经济效益和环境效益.
Abstract
To explore the effect of organic and inorganic nitrogen on yield and quality of high erucic acid rape-seed,we studied the effects of 6 different treatments(pure organic fertilizer,pure inorganic fertilizer,20%,30%,40%,and 50%organic fertilizer substitution)on yield,quality,soil nutrients,and economic benefits of high erucic acid industrial rapeseed(cv Mianyou 309).The results showed that compared with pure chemical fertilizer,a cer-tain proportion of organic and inorganic nitrogen could significantly increase rapeseed yield.The yield of 30%or-ganic nitrogen treatment was the highest,reaching 3501.63 kg/hm2,which was 24.84%higher than that of pure or-ganic fertilizer and 23.47%higher than that of pure inorganic fertilizer.Combination of organic and inorganic nitro-gen promoted the growth and development of the main stem and branches of rapeseed.Under this treatment,the eru-cic acid content was not affected but the oil content was also increased,so as to significantly increase the erucic ac-id and edible oil yield per unit area.It also increased the soil nitrogen storage,so that the soil might maintain a high-er fertility level for higher economic and environmental benefits.
