玉米施用不同有机肥肥效对比试验

Comparative Experiment on Fertilizer Effect of Different Organic Fertilizers Applied to Maize

为优化玉米栽培施肥技术,提高种植效益,在呼伦贝尔市扎赉诺尔区开展了玉米施用有机肥和复合肥的不同施肥方式的肥效对比试验,并从玉米的生物学形状、产量和经济效益3个方面进行了分析。结果显示,底肥施用有机肥+追肥施用复合肥方式相对于底肥和追肥均施用复合肥方式下的玉米的产量和经济效益均有所提升,在当地大田生产中具有推广价值。

To further optimize the cultivation and fertilization technology of maize and improve the planting economic benefit,a comparison experiment of different fertilization methods of organic fertilizer and compound fertilizer was carried out in Jalainur district of Hulun Buir City,and the biological shape,yield and economic benefit of maize were analyzed.The results showed that the yield and economic benefit of maize under the combination of organic fertilizer and topdressing were improved compared with that under the combination of bottom fertilizer and topdressing,and it had the value of popularization in local field production.
