摘要
【目的】针对当前秸秆生物反应堆菌种使用较为杂乱的问题,筛选适用于陕西关中地区温室黄瓜种植的秸秆生物反应堆的配套菌种。【方法】选取7种不同来源的菌种,测定不同菌种对日光温室土壤温度、黄瓜农艺性状、产量和抗病性等指标的影响,以不放置菌种为对照,对其效果进行综合评价。【结果】与对照相比,7个菌种均能提高温室土壤温度,促进黄瓜生长发育,提高黄瓜产量,降低黄瓜白粉病的发病率。其中经世明生物反应堆专用菌种001、秸秆生物降解专用菌种和来自西北农林科技大学植物保护学院的Z1处理后,土壤温度分别较对照提高3.3,3.1,2.4℃,黄瓜株高分别较对照增加26.8,22.2,25.0cm,单果质量分别较对照增加44.9,32.9,26.9g,白粉病病情指数分别较对照降低18.88,10.38,6.07,增产率分别为32.5%,27.1%,21.0%。【结论】在关中地区黄瓜日光温室栽培中,世明生物反应堆专用菌种001综合表现最为突出。
[Objective] The experiment was conducted to investigate and screen the optimal microbial strain for cucumber planted in greenhouse at Guanzhong,Shaanxi,in order to solve the confusion in use of bioreactor microbial strains. [Method] Seven microbial strains from different sources were used for treatments and the treatment without any microbial strain was used as control. Agronomic traits, yield and disease resistance of cucumber and soil temperature were measured and the effect of microbial strain was evaluated synthetically. [Result] Compared with the control, 7 microbial strains all increased the temperature of soil,promoted the growth and yield of cucumber,and reduced the disease incidence of powdery mildew. Shiming special straw bioreactor landfill microbial strain 001 （T3）, straw bioreactor landfill degradation of special microbial strain and Z1 of Northwest A＆F University increased the soil temperature in the greenhouse by 3.3,3.1,and 2.4 ℃ ,increased the plant height by 26.8,22.2,and 25.0 cm,increased the single fruit weight by 44.9,32.9,and 26.9 g,reduced the disease index by 18.88,10.38,and 6.07,and increased the yield by 32.5% ,27.1 % ,and 21.0% ,respectively. [Conclusion] Shiming special straw bioreactor landfill microbial strain 001 was recommended for cucumber planting in greenhouse at Guanzhong, Shaanxi.
