不同有机肥施用量对玉米产量的影响

The Effects of Different Application Rates of Organic Fertilizer on Maize Yield

为研究不同有机肥施用量对玉米产量的影响,以‘郑单958’为供试材料,单施化肥为对照(CK),设置5个处理,分别为T1处理:有机肥施用量1000 kg/hm^(2),T2处理:有机肥施用量1500 kg/hm^(2),T3处理:有机肥施用量2000 kg/hm^(2),T4处理:有机肥施用量2500 kg/hm^(2),T5处理:有机肥施用量3000 kg/hm^(2),研究不同施肥处理对玉米农艺性状、穗部性状和产量的影响。结果表明,和CK相比,施有机肥可显著增加玉米株高、穗位高和茎粗,降低秃尖长和空杆率,提高出籽率、穗粒数和千粒数,其中T4处理产量最高,比CK高出27.61%,可见,常规施肥基础上增施有机肥2500 kg/hm^(2)可显著促进玉米生长,提高玉米产量。

In order to study the effect of different organic fertilizer application rates on maize yield,'Zhengdan 958'was used as the test material,with single application of chemical fertilizer as the control(CK).Five treatments were set up:T1 treatment with 1000 kg/hm^(2) of organic fertilizer,T2 treatment with 1500 kg/hm^(2) of organic fertilizer,T3 treatment with 2000 kg/hm^(2) of organic fertilizer,T4 treatment with 2500 kg/hm^(2) of organic fertilizer,T5 treatment with 3000 kg/hm^(2) of organic fertilizer.The study examined the effects on agronomic traits,ear traits,and maize yield.The results showed that compared with CK,the application of organic fertilizer significantly increased the plant height,ear height and stem diameter,reduced the bald tip length and empty stem rate,and improved the seed setting rate,grain number per ear and thousand grain number.The yield of T4 treatment was the highest,which was 27.61%higher than that of CK.It's evident that adding 2500 kg/hm^(2) of organic fertilizer to conventional fertilization could significantly promote the maize growth and increase the yield of maize.
