摘　　要：为了明确新型解硅菌剂阿氏芽孢杆菌解硅微生物菌剂MB35-5在日光温室黄瓜中的应用效果,并为新型生物解硅菌剂在实际生产中应用提供理论依据,通过大田试验与室内分析相结合的方法,研究了阿氏芽孢杆菌解硅微生物菌剂MB35-5对日光温室黄瓜土壤有效硅含量以及黄瓜生长、产量和抗病性的影响。结果表明:在不施用外源硅的条件下,施用微生物菌剂MB35-5能够有效补充黄瓜生长消耗的土壤有效硅,施用量为3 000和6 000 g/hm^(2)处理黄瓜收获后的土壤有效硅含量分别较播前增加了13.8%和16.1%,分别较CK增加了24.6%和27.2%;能够显著促进黄瓜植株生长,有效增强抗病性,明显提高黄瓜产量,施用量为3 000和6 000 g/hm^(2)处理的产量分别较CK增加8.8%和11.9%。施用量6 000 g/hm^(2)处理在补充土壤有效硅、提高黄瓜产量、增强黄瓜抗病性方面的效果优于施用量3 000 g/hm^(2)处理,在实际生产中建议MB35-5的施用量为6 000 g/hm^(2)。In order to clarify the application effect of the new silicolytic agent Bacillus abelsii MB35-5 on cucumber in solar greenhouse,and provide theoretical basis for the practical application of the new biological silicolytic microbial agent in production,the effects of silicolytic agent B.abelsii MB35-5 on the soil available silicon content,and the growth,yield,and disease resistance of cucumber in solar greenhouse were studied by combining field experiments with indoor analysis.The results showed that under the condition of not applying exogenous silicon,the application of MB35-5 could effectively supplement the soil available silicon consumed by cucumber growth.The soil available silicon content after cucumber harvest increased by 13.8%and 16.1%compared to before sowing,and increased by 24.6%and 27.2%compared to CK,respectively,at the application rates of 3000 and 6000 g/hm^(2).It could significantly promote the growth of cucumber plants,effectively enhance disease resistance,and significantly increase cucumber yield.The yield of treat ments with application rates of 3000 and 6000 g/hm^(2) increased by 8.83%and 11.9%compared to CK,respectively.The application rate of 6000 g/hm^(2) was better than the application rate of 3000 g/hm^(2) in supplementing soil available silicon,improving cucumber yield,and enhancing cucumber disease resistance.In actual production,it is recommended to use a rate of 6000 g/hm^(2) for MB35-5.
