Background
At the present stage of China, the sugarcane pesticide fertilizer mainly comprises nitrogen, phosphorus and potassium compound fertilizer fertilizers and pesticides (thiamethoxam, clothianidin, monosultap, dinotefuran, chlorantraniliprole and the like), but the nitrogen fertilizer effect periods of the fertilizers are within 55 days, and medium and trace elements necessary for plant growth are lacked, and the pesticide effect period of the pesticides added by the conventional method in soil is not more than 4 months, so that the quality of sugarcane crops with longer growth period is reduced, the yield is limited due to the lack of the medium and trace elements, late fertilizer removal, insect damage and other factors, the yield and the quality of the sugarcane crops are always in no state, and even fall back, and the yield and the income increase of sugarcane farmers are seriously influenced. Some fertilizers are also added with medium and micro fertilizers, but the compounds of the medium and micro fertilizers react with orthophosphate and carbonate to ensure that the phosphorus and the medium and micro fertilizers which take part in the reaction are ineffective. Therefore, under the condition of severe shortage of young labor in rural areas, the sugarcane pesticide fertilizer with comprehensive functions, stable fertilizer effect and pesticide effect, long lasting period and remarkable yield increasing effect is expected by farmers.
