微生物肥料对棉田土壤生态与棉花生长的影响

Effects of microbial fertilizer on the soil ecosystem and growth of cotton

  • 摘要: 试验研究微生物肥料对棉田土壤生态与棉花生长的影响结果表明,单一施用微生物肥料或与有机肥混施均可改善土壤生态,提高土壤肥力,降低土壤容重,提高阳离子代换量,增加土壤速效磷、碱解氮和速效钾含量,棉花产量分别比对照提高19.2%和31.6%,且微生物肥料与有机肥混施效果优于单一使用。

     

    Abstract: Effects of microbial fertilizer on the soil ecosystem and growth of cotton were studied.The results show that microbial fertilizer,used alone or mixed with other organic fertilizers,can increase the total microbial biomass and improve the soil fertility.At the same time the unit weight of soil is decreased,and the cation exchange capacity,available P,alkaline hydrolysis N,and available K are increased.When microbial fertilizer is used alone,the yield of cotton increases by 19.2%,and when it is used together with organic fertilizers,the yield increases by 31.6% than CK.The efficiency of microbial fertilizer mixed with other organic fertilizers is better than that used alone.
