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/hm^(2),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。
To explore the effect of organic and inorganic nitrogen on yield and quality of high erucic acid rapeseed,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 certain proportion of organic and inorganic nitrogen could significantly increase rapeseed yield.The yield of 30%organic nitrogen treatment was the highest,reaching 3501.63 kg/hm^(2),which was 24.84%higher than that of pure organic fertilizer and 23.47%higher than that of pure inorganic fertilizer.Combination of organic and inorganic nitrogen promoted the growth and development of the main stem and branches of rapeseed.Under this treatment,the erucic acid content was not affected but the oil content was also increased,so as to significantly increase the erucic acid and edible oil yield per unit area.It also increased the soil nitrogen storage,so that the soil might maintain a higher fertility level for higher economic and environmental benefits.
