摘要
根据鲜食玉米营养特性和新型肥料的供肥特性,设计施用氮磷钾养分总量360 kg/hm2为适宜用量的中心项,并采用不同新型肥料(缓控释肥料和生物有机专用肥)一次性施用技术,与常规化肥进行比较,旨在探讨鲜食玉米高效施肥技术。结果表明,鲜食玉米有机无机专用肥会显著地影响玉米产量的构成因子,提高其指标含量;使用鲜食玉米有机无机专用肥处理的玉米增产幅度最高,较对照增产36.12%,纯增收增加6 606.0元/hm2;玉米收获后不同施肥处理的土壤速效养分存在差异,施用有机无机专用肥和控释复合肥处理的土壤速效养分均高于常规化肥的处理;施用控释复合肥的土壤速效养分均高于施用有机无机专用肥。
According to the nutrient characteristic of fresh corn and supply nutrient of new type of fertilizers,360 kg/hm^2 of NPK nutrient was suitable dosage applied with fertilizer,different new types of fertilizers（controlled release fertilizer and bioorganic special fertilizer） were used for application technology of one time. Comparing with conventional fertilizer,the aim of the study was to explore the efficient fertilization technology of fresh corn. The results showed that organic and inorganic fertilizer could significantly affect corn yield components and improve their contents. The maize production of organic and inorganic fertilizer treatment was most,it rose 36.12% than control,net income increased 6 606 yuan/hm^2. Soil available nutrients of different treatments after corn harvest were different,organic and inorganic special fertilizer application and controlled release compound fertilizer application were higher than conventional fertilizer treatment,controlled release compound fertilizer application were higher than organic and inorganic special fertilizer application.
