复合生物肥料具有养分全面，肥效持久，速缓兼效等优点，是一种新型的全价肥料。早稻一次性基施复合生物肥料并适量配施尿素，具有明显促蘖增穗的作用。每公顷基施１５００ｋｇ复合生物肥加施１２０ｋｇ尿素的每平方米有效穗比与其ＮＰＫ养分总量相近的化肥复合肥（每公顷施７５０ｋｇ）的增加５１～６１．５个穗，提高１４．５９％～１７．８３％；每公顷增收稻谷７７２．５～８８６．５ｋｇ，增产１５．６３％～１８．０４％。本试验结果还显示，施用复合生物肥料比施等量的基质肥（未添加有益微生物）每公顷增收稻谷１４２．５ｋｇ，增产２．７６％～２．７７％。表明复合生物肥料中的有益微生物具有一定的增效作用
The compound biological fertilizer has the advantages of complete nutrients, lasting fertilizer effect, rapid and effective, and is a new type of full-price fertilizer. One-time early rice base compound bio-fertilizer and fertilizer with appropriate amount of urea, with a significant role in promoting tillering by ear. The effective spike per square meter per hectare based on 1500kg compound bio-fertilizer plus 120kg urea increased by 51 ~ 61.5 spike, increased by 14.59% than that of fertilizer compound fertilizer with the same amount of NPK nutrients (750kg / ha) ~ 17.83%; 772.5 ~ 886.5kg of paddy per hectare income increase, yield 15.63% ~ 18.04%. The results also showed that the application of compound biological fertilizer than the same amount of substrate fertilizer (without added beneficial microorganisms) per hectare increased 142.5kg of rice, yield 2.76% ~ 2.77%. It indicates that the beneficial microorganisms in the compound biological fertilizer have certain synergistic effect
