摘要
江西红壤稻田三熟制条件下 ,双低油菜新品种中双 7号合理配施氮磷钾复混肥 (纯N 2 40kg/hm2 、P2 O56 0kg/hm2 、K2 O 90kg/hm2 和硼砂 15kg/hm2 ) ,有利于提高植株养分含量 ,保持养分平衡 ,增加生物学产量 ,菜籽产量达到 2 437.5kg/hm2 ,与NK、NP和N等施肥处理比较 。
The effects of application N, P and K fertilizers on the double-low rapeseed cultivar Zhongshuang No.7 were investigated under red paddy soil of two-crop paddy and rapeseed cropping system in Jiangxi province. Approaches of applying N 240kg/hm 2, P 2O 5 60kg/hm 2, K 2O 90kg/hm 2 and boron fertilizer 15kg/hm 2 were recommended for increasing content of plant nitrogen and phosphorus during the growth stages. In this experiment the biomass was increased and yield of Zhongshuang No.7 was 2 437.5kg/hm 2, which significantly higher than NK, NP and N approaches.
