Insect-prevention fertilizer for sugarcane and insect-prevention method for sugarcane

Abstract

The invention provides an insect-prevention fertilizer for sugarcane and an insect-prevention method for sugarcane, and relates to the technical field of planting. The insect-prevention fertilizer forsugarcane is prepared from the following raw materials: urea, ammonium bicarbonate, human and animal excreta, sodium humate, borax, ammonia water, plant ash, grain slag, tobacco stems, winery lime sludge, mushroom slag, an insecticide composition and water. The insect-prevention fertilizer for sugarcane provided by the invention is not added with any harmful substances from a formula to a production process; and the obtained insect-prevention fertilizer is scientific and reasonable in formula, is simple in preparation, is prepared according to characteristics of sugarcane, provides sufficientnutrients for growth of sugarcane, is matched with an insect-prevention method to inhibit generation of various funguses, so that various diseases of sugarcane are prevented, a survival rate of the sugarcane is increased, the sugarcane yield is increased, and economic benefits are increased.

Description

【Technical field】 [0001] The invention relates to the technical field of planting, in particular to an insect-proof fertilizer for sugarcane and an insect-proof method for sugarcane. 【Background technique】 [0002] Sugarcane is an annual or perennial perennial tropical and subtropical herbaceous plant. It is a C4 crop. It has the characteristics of long growth period, high photosynthetic intensity, high yield and high nutrient consumption. It is an economic crop that requires a large amount of fertilizer. The annual biological yield of sugarcane is generally as high as 5-7 tons above ground, some even as high as 10 tons or more. It is the main sugar crop in my country. [0003] According to research, each ton of sugarcane needs to absorb 1.5-2kg of nitrogen, 0.4-0.5kg of phosphorus, 2-2.7kg of potassium, 0.46-0.75kg of calcium, and 0.5-0.75kg of magnesium from the soil. It can be seen that fertilizers have become the most important for sugarcane. means of production. Howev...

Problems solved by technology

However, for a long time, unreasonable fertilization has generally existed in sugarcane in my country. Specifically, the formula of fertilizer is unreasonable, the application technology is unreasonable, and the utilization rate of fertilizer is low.

The formula seriously deviates from the principle of balanced fertilization, the fertilizer is not targeted and the fertilization is unreasonable, which will eventually lead to a decrease in the yield and sugar content of sugarcane, and at the same time cause waste of fertilizer and environmental pollution

[0004] Secondly, in recent years, sugarcane borers, thrips, cotton aphids, scale insects, cane turtles, termites and other insect pests have become important obstacles to sugarcane production, causing certain losses to sugarcane yield and quality. The damaged area is as high as 80%. A large amount of manpower and material resources must be invested in the prevention and control of

[0005] In addition, in the existing special fertilizers for sugarcane, the content of nitrogen, phosphorus and potassium is low, and the proportion of other auxiliary materials is too large. Fertilization needs to be applied several times a year, and the amount is large to meet the demand.

At present, it is necessary to ditch and apply basal fertilizer and insecticidal composition before sugarcane planting or perennial root germination every year, and then spray insecticides in 2-3 times, which not only increases labor intensity, labor costs and pesticide expenses, but also is difficult to control. The timing of pesticide application often causes losses due to the delay of the best control period

Now sugarcane pest control generally adopts phoxim as the sugarcane insecticidal composition, but its effective period in the soil is no more than 30 days, and the pests cannot be effectively controlled during the sugarcane growth period. Therefore, a scientific, reasonable and effective sugarcane pest control method letter for further study
