【摘要】 蔬菜的沼肥农用在内地已经有了很多成熟的经验,但在新疆有关这方面的研究比较少。本研究田间试验研究了沼肥与化肥配合施用对豆角和白菜产量、品质、农残、硝酸盐含量的影响,结果表明:蔬菜施用沼肥可明显提高产量、改善品质,并降低农残及硝酸盐的含量,同时还显著改善了土壤的肥力性状,综合比较各施肥处理的效果,以豆角处理4即沼渣、尿素、三料磷肥、硫酸钾分别施用30000 kg.hm-2,225 kg.hm-2,400 kg.hm-2,75 kg.hm-2和大白菜处理4沼渣、尿素、三料磷肥、硫酸钾分别施用30000 kg.hm-2,300 kg.hm-2,300 kg.hm-2,60 kg.hm-2为最佳施肥方案。更多还原

【Abstract】 Compared to other parts of China,there are few researches to study the application of biogas fertilizer to vegetable crop in XinJiang autonomous region.Therefore,a field experiment was carried out to study the effect of combination application of biogas fertilizer and chemical fertilizer on yield,quality,pesticide residue,and nitrate content for beans and Chinese cabbages.The results indicated that application of biogas fertilizer significantly increased the yield,improved quality,and decreased nitrate content.Meanwhile,soil fertility was significantly improved too.By comprehensive analyses of different treatments,the combination treatment of biogas residue 30 000 kg·hm-2,carbamide 225 kg·hm-2,phosphate fertilizer 400 kg·hm-2,potassium sulfate 75 kg·hm-2 for bean,and that of biogas residue 30 000 kg·hm-2,carbamide 300 kg·hm-2,phosphate fertilizer 300 kg·hm-2,potassium sulfate 60 kg·hm-2 for Chinese cabbage,are the best treatments.更多还原
