摘　　要：以宁春4号为参试品种,比较沼肥做基肥和追肥不同施用方式及施用量对春小麦产量及其构成的影响.结果表明:沼肥做基肥和追肥均可显著提高小麦产量,做基肥最高增产达到10%,做追肥最高增产幅度达到8.7%.产量增加的同时,产量构成因素粒质量、粒数也随着施肥量的增加而增多.建议沼肥做基肥时适宜施用量为1 000~2 000 kg/666.7 m^2,做追肥时适宜施用量为1 800~2 000 kg/666.7 m^2.The tested crop variety was Ningchun 4. The experiment compared the effects on the yield and composition of spring wheat under conditions that the biogas manure was applied either to be the base fertilizer or to be the additional fertilizer with different application amount. The results of the experiment showed that the biogas manure can improve the wheat yield dramatically whether it acted as the base fertilizer or as the additional fertilizer. The maximizing yield could be improved by 10% and 8.7% when the biogas manure was applied to be the base fertilizer and additional fertilizer, separately. Yield components, such as grain weight and grain numbers, increased while the yield increases. Therefore, it is suggested that the application amount of he biogas manure be 1.5 kg/m^2 to 3 kg/m^2 or be 2.7 kg/m^2 to 3 kg/m^2 when it is applied as the basic fertilizer and the additional fertilizer, separately.
