沼液施用水果玉米技术研究与推广

Research and popularization of biogas slurry application on fruit maize

文章研究沼液在雪甜7401水果玉米上的施用,结果表明,虽然沼液施用对水果玉米的产量、秃尖等经济性状的影响不如化学肥料,但施用沼液的水果玉米在口感品质方面较优,尤其是在毎667 m^(2)利用30 000 kg沼液作为基肥,追肥10 000 kg沼液+尿素10 kg,穗肥20 000 kg沼液+硫酸钾10 kg处理中,这种施肥方式能够增加果穗行数、缩短秃尖,有效提升玉米可溶性糖含量和产量,既能稳产,又提升了品质;同时可减施复合肥50 kg、尿素15 kg,适宜在生产中大面积推广。

In this study,the application of biogas slurry to fruit maize variety Xuetian 7401 was studied.The results showed that although the effect of biogas slurry application on the yield and baldness of fruit maize was not as good as that of chemical fertilizer,the taste quality of fruit maize applied with biogas slurry was superior.In particular,30000 kg of biogas slurry was used as base fertilizer,10000 kg of biogas slurry+10 kg of urea was used as topdressing,and 20000 kg of biogas slurry+10 kg of potassium sulfate was used as ear fertilizer for every 667 m^(2).This fertilization method increased the number of kernel rows,shortened the bald tip,and effectively improved the sweetness and yield,which could not only stabilize the yield,but also improve the quality.At the same time,compound fertilizer can be reduced by 50 kg and urea by 15 kg,which is suitable for large-scale promotion in production.
