Effects of Biogas Slurry on Yield,Quality and Control on the Disease and Pest of Leaf Mustard
摘要
Abstract
In order to explore methods of the reasonable resource utilization on biogas slurry,provide a refer-ence for local biogas slurry agricultural,adjust measures to guide agricultural production with local conditions,and reduce agricultural production costs,this study researched the effect of biogas slurry on leaf mustard yield,quality and control on the disease and pest,explored the application amount of biogas slurry under leaf mustard yield,quali-ty and pest control best-case situation.Compared with the fertilizer control(CK2),in the most areas with biogas ap-plication slurry the production of leaf mustard had improved,nutritional quality of leaf mustard had improved,leaf mustard grow better,the yield of leaf mustard were maintained at a relatively high level when the biogas slurry that instead of fertilizer application rate was controlled in the range of 83 333 to 108 333 kg/ha;the quality of leaf mus-tard achieved the best when the biogas slurry that instead of fertilizer application rate was controlled in the range of 91 667 to 108 333 kg/ha,considering the output and quality of leaf mustard,the biogas slurry used instead of chem-ical fertilizer would be optimal at 91 667-108 333 kg/ha. A moderate amount of biogas slurry spraying had the benefits to diseases and insect pests prevention and control of leaf mustard. When the biogas slurry seems control during 1 750-2 500 kg/ha,leaf mustard hundred plant bug number close to CK2;when applying biogas slurry con-tent control during 2 250-2 500 kg/ha,the rates of insect pest and disease index mustard were relatively minimum and close to CK2,so in this study,leaf mustard pest control effect was relatively better when the biogas slurry that instead of pesticides application rate was controlled in the range of 2 250 to 2 500 kg/ha. In summary,through the application of compares with two groups of contrast (CK1 and CK2),application of biogas slurry can significantly improve the production of leaf mustard,ensure the good quality of leaf mustard,as well as has good benefit to plant diseases and insect pests prevention and control of leaf mustard,but growth on various aspects of the demand of leaf mustard can be ensured,when application of biogas slurry is controlled in applying a certain content and reasona-ble,and improve the efficiency of the use of biogas slurry.关键词
