生物菌肥是经人工在特定条件下培养的有益微生物制成的有生命的肥料,又称微生物肥料。生物菌肥大体可分为以下两类。一类是菌种单一、功能单一的一般菌肥,主要依靠一种有益微生物的生命活动产物来增加土壤中植物所需的某一种营养要素(氮、磷或钾),以补充作物生长发育之需,达到增产目的。这类菌肥的局限性一是对作物专一性强,一般只能用于一
Bio-bacterial fertilizer is a living fertilizer made of beneficial microorganisms cultured under specific conditions, also known as microbial fertilizer. Biological fertilizer can be divided into the following two categories. One kind is a kind of common bacterial fertilizer with single species and single function, which mainly relies on the life activity products of one beneficial microorganism to increase a certain nutrient (nitrogen, phosphorus or potassium) needed by plants in the soil to supplement crop growth and development The need to achieve the purpose of increasing production. One of the limitations of these bactericides is the specificity of the crop, generally only for one
