Description
Technical field
The present invention relates to pesticide field, particularly a kind of agricultural chemicals list agent that contains mesotrione is mainly used in the comprehensive management of weeds of cassava Tian Miaohou.
Background technology
Cassava is introduced China in 1820s, has been distributed widely in the South China at present.In this area, cassava has become the fifth-largest crop that is only second to paddy rice, sweet potato, sugarcane and corn, is one of important source of finance of peasant household, and under the promotion of Ministry of Agriculture's encouragement policy, and its cultivated area is also in year by year increase.On the main application of China cassava is feeding and industry, develop, piece root starch is that one of main system starch material is gone up in industry; On fermentation industry, but tapioca or dry plate preparing alcohol, citric acid, glutamic acid, lysine, protein cassava matter, glucose, fructose etc., and these products all have important use at aspects such as food, beverage, medicine, weaving (dying cloth), papermaking; The micromicro of piece root utilizes with as fertilizer sources and animal feed once more; Discarded fiber can be used as flocculant and is used for mining industry after drying, the low concentration starch that in precipitation process, runs off then can be used as pig feed; Simultaneously, under our times food and energy crisis, cassava is used for producing alcohol and has the simple and low advantage of cost of technology as a kind of new biomass energy, has become a kind of desirable substitute products, and development cassava industry is all paid much attention in the whole world.Because domestic some areas vehicle has been brought into use ethanol petrol, impels the alcohol consumption market conditions to be expected to rise, and has stimulated the great amount of investment of Alcohol Production industry.On June 7th, 2007; State Council holds the renewable energy resources meeting, and industrial policy is adjusted, and prohibites with corn and makees raw material production alcohol; The industry cassava that begins to be widely used does and makes non-grain ethanol as primary raw material, has spurred the great demand to cassava thus more.Only Guangxi cassava area has just reached more than 450 ten thousand mu now, and number is surprising, yet influences the archenemy of cassava production and quality---and the cassava field weed is corroding the people's interests day by day.
