除草剂复配对高粱产量及土壤酶活性的影响
Study on Yield of Sorghum and Soil Enzyme Activity in Combination with Herbicides
摘要
Abstract
Weeds seriously reduce crop yield and are an urgent problem in agricultural production.The combination of her-bicides can effectively control weeds and increase agricultural economic benefits.In this study,the effects of herbicide compound on sorghum production and soil enzyme activity were measured by using the mixture before and after seedling.The results showed that there were no significant differences in chlorophyll content,plant height,leaf number,ear length and stem diameter between treatment groups and control group 30 days after spraying herbicide.The damage rate of sor-ghum seedlings was 7.67%～86.87%.The activities of urease,sucrase,acid phosphatase and H2O2 in soil treated with C2 and C10 were significantly higher than those treated with ck.To sum up,C1,C4,C6,C7,C11 and C12 have serious damage to sorghum seedlings and are not recommended to be used,while C2 and C10 are less harmful to sorghum and can improve soil enzyme activity.Due to different ecological environment composition in different regions,herbicides should be used reasonably according to local actual needs in production.关键词
