摘　　要：为了探究增施微生物肥料对长山药种植过程的影响,以传统老品种长山药为试验材料,通过2年的田间试验,测定长山药土壤理化性质、生长指标、品质、产量及经济效益。结果表明,2020年各处理中T3(复合肥+生物有机肥+微生物菌剂浸泡段子+追施2次微生物菌剂)效果较好,蛋白质含量和黏度较CK分别增加12.64%和17.54%,多糖含量降低30.18%;产量增加157.49%,总产值为581 141.74元·hm^(-2)。2021年选择经济效益最高的T3扩大面积示范种植进行验证,其产量为20 839.95 kg·hm^(-2),总产值为602 774.71元·hm^(-2),分别较2020年T3增加2.56%和3.72%。因此,结合长山药产量、农民纯收入等方面考察,复合肥+生物有机肥+微生物菌剂浸泡段子+追施2次微生物菌剂是最佳施肥方式。In this paper, in order to explore the effect of increasing microbial fertilizer on the planting process of long yam, the traditional old variety of long yam was used as the test material through a two years field experiment. Based on compound fertilizer, the physical and chemical properties, growth indexes, quality, yield and economic benefits of long yam soil were determined. The results showed that the T3 group treated with compound fertilizer+biological organic fertilizer+microbial agent immersion sections and two microbial agent topdressing worked better in each experimental group in 2020, protein and viscosity increased by 12.64% and 17.54% over the CK group, respectively, and polysaccharide decreased by 30.18%;the yield increased by 157.49%, and the total output value was 581 141.74 yuan per ha respectively.In 2021, we selected the T3 group with the highest economic benefit for demonstration planting of expanded area, among which the output was 20 839.95 kg per ha, the total output value was 602 774.71 yuan per ha, increased by 2.56% and 3.72% compared with group T3 in 2020. Therefore, considering the yield of long yam and farmer’s net income, group T3 with additional microbial fertilizer is the best fertilization method.
