摘要
[目的]分析4种复混肥在含山县马肝田水稻产区推广与应用的可行性。[方法]通过小区对比试验,研究农家福40%BB肥、农家福45%BB肥、地泉有机无机肥、绿都有机无机肥4种复混肥在含山县马肝田水稻生产中的施用效果、增产幅度及经济效益。[结果]参试的4种复混肥对水稻有明显的增产效果,水稻平均株高、单株有效穗数、穗长、单株分蘖数和产量均高于不施肥处理。4种复混肥对水稻生育期都有明显的促进作用,产投比在1.52-2.51,高于不施肥处理,且施用有机无机复混肥的经济效益较好。[结论]参试的4种复混肥可在含山县马肝田水稻产区大面积推广应用。
[Objective] The study was to analyze the feasibility of the popularization and application of 4 compound fertilizers in the rice producing areas with Magantian soil in Hanshan County.[Method] In the plot contrast tests,the application effect,yield-increasing amplitude and economic benefit of 4 compound fertilizers of farmhouse happiness 40% BB fertilizer,farmhouse happiness 45% BB fertilizer,Diquan organic-inorganic fertilizer and Lvdu organic-inorganic fertilizer in the rice producing area with Magantian soil in Hanshan county were studied.[Result] The 4 tested compound fertilizers all had obvious yield-increasing effect on rice,with which the average plant height,effective spikes number per plant,ear length,tillering number per plant and yield of rice were all higher than that without fertilization treatment.4 compound fertilizers all had obvious promoting effect on growth stages of rice,the ratio of output to input was between 1.52 and 2.51,which was higher than that without fertilization treatment,and the economic benefit by applying organic-inorganic compound fertilizer was better.[Conclusion] The 4 tested compound fertilizers could be popularized and applied in large area in the rice producing areas with Magantian soil in Hanshan country.
