摘要
为研究有机肥对玉米产量的影响,以不施商品有机肥为对照(CK),设置4个有机肥替代处理,分别为有机肥替代15%、30%、45%和60%研究玉米叶片光合参数、干物质积累量以及产量和产量构成因素。结果表明,施用有机肥显著增加净光合速率,显著提高了各生育期的干物质积累量,在有机肥替代化肥45%时达到最大值,产量达到13144.39kg/hm^(2)。因此,有机肥能够促进玉米生长,提高玉米产量,且在替代化肥45%时效果最好,能在生产中推广应用。
In order to study the effect of organic fertilizer on corn yield,four organic fertilizer substitution treatments with commercial organic fertilizer were set up,replacing 15%,30%,45%,and 60%(T4),respectively,using no application of commercial organic fertilizer as the control(CK).The study focused the photosynthetic parameters,dry matter accumulation,yield and its components.The results showed that applying organic fertilizer significantly increased the net photosynthetic rate and substantially raised the dry matter accumulation at various growth stage.The maximum value was reached when organic fertilizer replaced chemical fertilizer by 45%,and the yield reached 13144.39 kg/hm^(2).Therefore,organic fertilizers can promote corn growth and yield,with the best effect achieved when replacing chemical fertilizers by 45%,making it suitable for promotion and application in production.
