摘  要:
以春小麦品种甘春24号为指示品种,研究了不同氮磷配比和水肥配比对春小麦产量的影响。试验结果表明,在播种密度为675万株/hm2时,最优氮磷配比为P2O5180 kg/hm2、N 240 kg/hm2,产量可达8 333.33 kg/hm2;水肥配比各处理组合中,以灌水3 000 m3/hm2,氮磷配比为P2O5180 kg/hm2、N 240 kg/hm2时经济效益最高,产量达8 300.00 kg/hm2。

摘  要:
In order to find the best ratio of natrogen and phesphones fertilizer,this study investigated the effects of different ratios of natrogen and phesphones and ratios of water-fertilization on the yield of spring wheat Ganchun 24.The results indicated that the optimum application rate of nitrogen and phosphorus was P2O5 180 kg/hm2、 N 240 kg/hm2 and the yield could reach 8 333.33 kg/hm2 when the sowing density of Ganchun 24 was 6.75 million/hm2;The highest economic benefit of water and fertilizer combination treatments were irrigation 30 m3/hm2,N/P ratio P2O5 180 kg/hm2,N 240 kg/hm2,and the yield could reach 8 300.00 kg/hm2.
