摘要
采用田间小区对比试验方法 ,研究集成型化肥增效剂在推荐用量 (12kg/hm2 )下对 3种复合肥的增效作用。结果表明 :集成型化肥增效剂能促进水稻分蘖 ,增加水稻最后 3张功能叶鲜重 ,改善产量构成因素 ,显著提高产量。集成型化肥增效剂与复合肥配合施用能显著增加作物茎秆部分的氮、磷、钾累积量。集成型化肥增效剂与复合肥混施的增产作用大小依次为 :与NT型有机无机复合肥混施 >与JF型有机无机复合肥混施 >与普通复合肥混施。
Field plot contrast experiments were conducted to study the increase efficiency of integrated fertilizer synergist at 12 kg/hm 2 with three kind of compound fertilizers. It indicated that the application of synergist could promote rice tillering, increase fresh weight of the last three functional leaves, improve the constructive factors of yield and evidently raise the output of rice. The accumulation of nitrogen, phosphorus and potassium of treated rice crop, especially in straw, was increase evidently. The order of efficiency increase to the compound fertilizers was: applying with NT type organic inorganic compound fertilizer>with JF type organic inorganic compound fertilizer>with common compound fertilizer.
