摘要：

本研究以黑土作为供试土壤，采用盆栽的方法，对生物型水稻专用肥应用效果进行初步研究。结果表明，生物型肥料有效的促进水稻在整个生育期内对钾的吸收，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4.3%-8.1%。生育后期生物型肥料处理的土壤中速效养分含量仍高于等养分化肥处理，表现出良好的长效机制。减少化肥用量的生物型肥处理与常规施肥相比，氮、磷、钾的利用率分别提高11.8%、18.9%和26.6%。生物型I处理产量显著高于其他处理，水稻品质好于其他处理，但未达到显著水平。

Abstract:

Pot experiments were conducted to preliminary study the effects of biotype rice specific fertilizers in black soil. The results indicated that all biotype rice specific fertilizers could promote potassium absorption and increase plant biomass in all growth stages. Plant dry weights of using biotype rice specific fertilizers treatment are 4.3%-8.1% higher than chemical fertilizer treatments contain equal nutrient contents at heading stage. The content soil available nutrients at the later growth stage is also higher in biotype rice specific fertilizers treatment than that in chemical fertilizer treatments, indicating the better effects of biofertilizers. Compared with common fertilizer treatment, the using efficiency of nitrogen, phosphorus and potassium for biotype fertilizer I treatment increased 11.8%, 18.9% and 26.6%, respectively. The yield of biotype fertilizer I treatment is higher significantly than other treatments. The quality of biotype fertilizer I treatment rice better than other treatments, but didn’t reach notable leave.
