【摘要】 为研究不同配方缓控释肥肥效,寻求关中灌区夏玉米缓控释肥氮磷钾最优配方,陕西省宝鸡市陈仓区安排了等养分条件下不同配方缓控释肥肥效试验。试验结果表明:施用缓释掺混肥(26-11-12)、配方肥(29-6-9)、控释肥(28-6-6)较习惯施肥分别增产89.3 kg·667 m-2、69.3 kg·667 m-2、37.8 kg·667 m-2;增产率为13.4%、10.4%、5.7%;增收151.8元·667 m-2、117.8元·667 m-2、64.3元·667 m-2

【Abstract】 In order to investigate the fertilizer efficiency of different slow and controlled release fertilizers and find an optimal formula of N, P and K for summer maize in Guanzhong irrigated area, a fertilizer efficiency experiment of different slow and controlled release fertilizers was conducted in Chencang District of Baoji under same nutrient condition.The results showed that slow-release mixed fertilizer(26-11-12), formulated fertilizer(29-6-9) and controlled-release fertilizer(28-6-6) respectively increased the yield by 89.3 kg·667 m-2, 69.3 kg·667 m-2 and 37.8 kg·667 m-2,and increasing rate of the yield was 13.4%, 10.4% and 5.7%, and the income increased by 151.8 yuan·667 m-2, 117.8 yuan·667 m-2 and 64.3 yuan·667 m-2.
