摘要
以草甸黑土作为供试土壤,对生物型水稻专用肥应用效果进行小区试验。结果表明：生物型肥料有效的提高水稻植株的生物量,抽穗期生物型水稻专用肥处理的水稻植株干重比等养分化肥处理高13.36%~23.28%。生物菌肥的施入能够提高水稻产量,在常规施肥基础上增施生物菌肥和减量化肥增施生物菌肥两个处理分别比常规施肥产量提高5.5%和7.9%。
Plots experiments were conducted to preliminary study the effects of biotype rice specific fertilizers in meadow soil.The results indicated that all biotype rice specific fertilizers could increase plant biomass in all growth stages.Plant dry weights of using biotype rice specific fertilizers treatment were 13.36%～23.28%,higher than that of chemical fertilizer treatments contain equal nutrient contents at heading stage.The yields of biotype fertilizer treatments were higher than that of the equal nutrient contents treatments 5.5% and 7.9%,respectively.
