有机无机氮配施对高芥酸油菜绵油309产量及品质的影响
Effect of organic and inorganic nitrogen combined application on yield and quality of high erucic acid rapeseed cv Mianyou 309
摘要
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.关键词
