摘　　要：为解决成都温江区大蒜种植障碍,特研究不同施肥方式和用量对温江大蒜产量、种植区土壤理化性状以及微生物数量的影响。结果表明,生物有机肥6000、9000、12000 kg/hm^(2)与复合肥配施这3种处理的土壤总体速效养分含量、微生物总量明显高于仅施用复合肥750、1125、1500 kg/hm^(2)的处理。其中,施用6000 kg/hm^(2)的DL 1产量为12947.3 kg/hm^(2),虽不是最高,但投入产出比(8.42)最高,细菌/真菌数(359)最高,建议推广使用。In order to solve the obstacle of garlic planting in Wenjiang district,the effects of different fertilization methods and dosages on Wenjiang garlic production,soil physical and chemical properties of planting area,and microbial quantity were studied.The results showed that the total soil available nutrient content and the total microbial numbers of the three treatments of bio-organic fertilizer 6000,9000,12000 kg/hm^(2) combined with compound fertilizer were significantly higher than those of the treatment only applying compound fertilizer750,1125,1500kg/hm^(2).Amongthem,theyield of DL_(1) appliedwith6000kg/hm^(2) was 12947.25 kg/hm^(2),which was not the highest,while the ratio of the output value to fertilizer cost(8.42)and the bacteria number to fungus number(359)was the highest.Therefore,it was recommended for promotion.
