Malipo Tobacco Comprehensive Prevention And Control Technology Screening And Evaluation

For the problem in wenshan-malipo strike-slip disease in tobacco production is increasingly serious, we according to the current main methods of disease control combined with the wenshan-malipo strike-slip the truth in a series of local disease research, achieved good results, the results are as follows:From varieties, cultivation and soil of malipo tobacco disease in three aspects, researches control effects, the results are as follows:from variety trials found that yanyan97 relative to the control over yunyan87 and 6517 and K346 and PVH2254,it has higher yield, longer suitable baking period;Has strong resistance for many diseases, including high with bacterial wilt performance, the wildfire disease, Angle spot disease of disease; But the major epidemic diseases for bacterial wilt, integrated all aspects of performance, recommended in yanyan97 replace yunyan87 as wenshan-malipo strike-slip introduced.cultivation variety.We took from the cultivation method, Interplant spring onion on the test results show that the interplanting of tobacco plant has none of resistant effect, but it can obviously improve flue-cured tobacco production, improve the economic benefit.Adopted a series of measures from the aspects of soil, and achieved good results, the results are as follows:Soil disinfection can effectively kill pathogenic bacteria and viruses, elegans in the soil nematodes, can effectively reduce soil borne disease.The Test showthat in the wenshan-malipo strike-slip local soil disinfection the growth potential of tobacco plant, the processing of production output value were significantly higher than control, and the soil borne disease significantly reduced.Visible soil disinfection effect on the economic benefits of the flue-cured tobacco growth, it is recommended that the soil borne disease incidence of serious plot of the smoke before soil disinfection.Flue-cured tobacco with organic fertilizer, reducing fertilizer not only keep the flue-cured tobacco production, and improve output value, the proportion of superior tobacco, improving the quality of tobacco leaves.Flue-cured tobacco fertilizer reduction with biological organic fertilizer decreased the flue-cured tobacco black shank disease incidence and disease index and bacterial wilt, and with the improvement of biological organic fertilizer seems, disease control, the more obvious effect.Up suddenly and violently bacteria farmyard manure as a fertilizer fermentation technology can quickly fermentation, and farmyard manure can rise to soil improvement, and the role of nutrients.In the tests, the farmyard manure plowing up suddenly and violently bacterium fermentation processing growth potential, yield and output value were higher than control.From the point of disease resistance, application of initiating the fungus block due to strong growth potential of tobacco plant, disease resistance, various diseases were but a little light;So suddenly and violently bacteria can be widely used in the farmyard manure fermentation, with tobacco compound fertilizer as tobacco fertilizer.Bacillus is yunnan star yao biochemical reagents, biological products co., LTD., production test, bacillus reagent can significantly reduce the root-stock disease epidemic effectively improve the economic benefitTest is mainly studied by the method of species selection, agricultural, some suitable wenshan-malipo strike-slip disease prevention and cure, can provide reference for the disease control in malipo tobacco production in the future.
