摘 要:采用田间小区试验,种植夏玉米,设计对照、垃圾复合肥、堆肥、化肥四种肥料处理,各有肥处理的氮、磷、钾含量相同.研究新型垃圾复合肥对夏玉米生育性状、产量、经济效益以及收获后土壤中养分状况的影响.结果表明:与化肥相比较,复合肥的合理使用更好的促进玉米苗期生长水平,有效的提高了玉米的株高、穗长、穗粒数、千粒重等玉米生育参数,使产量和经济效益在施用复合肥后明显提高;复合肥处理后的土壤中有机质、氮素含量明显增加,磷素、钾素以及碱解氮参数虽有所提高,但增长不显著,土壤整体养分状况得到改善.Four different fertilizers of CK, compound fertilizer produced with urban waste, urban waste compost, chemical fertilizer were treated with same N, P, K in this experiment in planting summer maize to research the soil fertility effects of compound fertilizer produced with urban waste, different bearing characters, output and economic benefits of summer maize, and the changes of the nutrients in the soil after harvest. The results showed that compared with chemical fertilizer and CK, the yields of summer maize increased greatly, organic material and total nitrogen in the soil enhanced after using urban waste compost and the compound fertilizer produced with urban waste. Compared with urban waste compost, compound fertilizer produced with urban waste showed better effect on the increase of the summer maize yield.
