专用缓释肥对夏玉米产量及肥料利用率的影响
Effect of special slow-release fertilizer on yield and fertilizer using efficiency of summer maize
摘要
Abstract
In order to confirm the effect of special slow-release fertilizer and realize the target of high yield and high efficiency fertilization technology of summer maize.Field experiment were conducted and the effect of special slow-release fertilizer were studied on yield,SPAD,nutrient accumulation and fertilizer using efficiency in summer maize.The results showed that for the experiments at Hebi and Xuchang,compared with the average nutrients common fertilizer application,the special slow-release fertilizer increased yield by 5.17％ and 5.65％ respectively,and compared with farmer's fertilizer practice,increased by 9.99％ and 5.34％ respectively.The nitrogen nutrient accumulation increased by 6.21％ and 7.97％ respectively,compared with the average nutrients common fertilizer application.The nitrogen fertilizer use efficiency increased by 7.66％ and 8.69％ respectively,compared with the average nutrients common fertilizer application.There were no significant influence on yield and nitrogen fertilizer use efficiency in special slow-release fertilizer compared with ordinary fertilizer applied twice.Special slow-release fertilizer (28-10-12,50％ slow release nitrogen) could promote nitrogen,phosphorus and potassium nutrient absorption and utilization in summer maize,and improve fertilizer using efficiency,with high yield and high efficiency and simplified fertilization by one-time basal fertilization 750 kg · hm-2 in the seedling stage.关键词
