摘要:

【目的】研究微生物菌剂防治甜菜根腐病的防治效果及对产量的影响。【方法】选用木霉菌(M)、枯草芽孢杆菌(B)、木霉菌+枯草芽孢杆菌(C)、荧光假单胞杆菌(P)、淡紫紫孢菌(D)、多粘芽孢杆菌(PP)6种微生物菌剂进行甜菜根腐病田间防治试验。【结果】经6种微生物菌剂处理,甜菜根腐病的发病率和病情指数与对照(CK)相比显著减低(P<0.05),发病率较对照降低18.18%~50.00%,病情指数降低2.27~5.87,各处理防效达到19.12%~49.45%,防效依次为C>D>B>P>M>PP。施用微生物菌剂能够改善甜菜根际土壤理化性状,其中M、B、C、D处理可增加土壤有机质的含量,6种微生物菌剂可显著增加速效氮、速效磷、速效钾的含量。施用微生物菌剂能够增加甜菜地上部、地下部及总干物质的积累,甜菜根产量和含糖率均高于对照,产糖量增产幅度达7.43%~38.05%,D、C和M产糖量增加效果最为显著(P<0.05),分别增产38.05%、28.49 %和19.78%。【结论】施用菌剂能活化土壤养分,木霉菌+枯草芽孢杆菌防效较好,优于木霉菌、芽孢杆菌单施,提高根际土壤有机质和速效养分的含量,同时能够增加甜菜地上部、地下部及总干物质的积累,甜菜根产量和含糖率均高于对照,产糖量增产幅度达7.43%~38.05%。微生物菌剂能够改善作物根际土壤理化性状,增加土壤中有机质、碱解氮、速效磷、速效钾含量,促进作物营养吸收和生长,提高作物产量。

Abstract:

【Objective】 explore the control effect of microbial agents on beetroot rot and its impact on yield.【Methods】 Six microbial agents were selected, namely Trichoderma(M), Bacillus subtilis(B), Trichoderma plus Bacillus subtilis(C), Pseudomonas fluorescentis(P), Purpuria purpuris(D), and Bacillus polymyxoplasmos(PP), to carry out experimental research on the field prevention and control of beetroot rot.【Results】 The results showed that the incidence and disease index of beetroot rot were significantly reduced compared with the control(CK)(P<0.05), the incidence rate was reduced by 18.18%-50.00%, the disease index was reduced by 2.27-5.87, the prevention effect of each treatment reached 19.12%-49.45%, and the prevention effect was C>D>B>P>M>PP. The application of microbial agents could improve the physicochemical properties of the rhizosphere soil of beets, among which M, B, C, D treatment couldincrease the content of soil organic matter, and 6 microbial agents could significantly increase the content of available nitrogen, available phosphorus and available potassium. The application of microbial agents could increase the accumulation of aboveground, underground and total dry matter of beet, the yield and sugar content of beetroot were higher than those of the control, the sugar production rate increases by 7.43% to 38.05%, and the sugar production of D, C and M was the most significant(P<0.05), with an increase of 38.05%, 28.49% and 19.78%.【Conclusion】 The results of soil nutrient and beet yield determination shows that the application of fungal agents can activate soil nutrients, and the control effect of Trichoderma + Bacillus subtilis is better, which is better than that of Trichoderma and Bacillus, which increases the content of organic matter and quick-acting nutrients in the rhizosphere soil, and at the same time increases the accumulation of aboveground, underground and total dry matter of beets, and the yield and sugar content of beetroot are higher than those of the control, and the sugar yield increases by 7.43%-38.05%. It can be seen that microbial agents can improve the physical and chemical properties of crop rhizosphere soil, increase the content of organic matter, alkaline nitrogen, available phosphorus and available potassium in the soil, promote crop nutrient absorption and growth, thus increasing the crop yield.
