Peanut pesticidal special fertilizer and production method thereof

Abstract

The invention discloses a peanut pesticidal special fertilizer. The fertilizer adopts tobacco waste as botanical pesticide to replace or partially replace the high-efficient, low-toxic and long-acting chemical pesticide, i.e. controlled-release phoxim. The fertilizer consists of the following components in percentage by weight: 15 to 20 percent of tobacco waste, 1.0 to 1.5 percent of controlled-release phoxim, 20 to 50 percent of nitrogenous fertilizer, 13 to 18 percent of phosphatic fertilizer, 9 to 16 percent of calcium superphosphate, 15 to 20 percent of potash fertilizer and 0.5 to 1.0 percent of borax. The produced fertilizer has the advantages of low toxicity, safety, environment-friendliness, simple technique, less investment, good field pesticidal effect and remarkable production and income-increasing effect.

Description

technical field [0001] The invention relates to the field of fertilizers in agricultural production, in particular to a special fertilizer for killing peanuts and a production method thereof. Background technique: [0002] Peanut is an important oil crop in my country. Because peanuts are often cropped continuously for many years, underground pests are more serious, which seriously affects the yield and quality of peanuts. In production, farmers often use highly toxic pesticides, endangering the safety of peanuts and causing environmental pollution. The invention uses soot residue and slow-release phoxim as raw materials as insecticides, and adds chemical fertilizers to produce peanut insecticide-specific fertilizers according to the nutritional characteristics of peanuts. The demonstration results of field experiments show that the application of special fertilizer for peanut insecticide can significantly reduce the underground pests of peanuts, reduce the defective fruit,...

AI Technical Summary

Problems solved by technology

my country is a big tobacco producing country, and its production accounts for 45% of the world. Henan, Guizhou, Yunnan, Anhui, Shandong, Northeast and other places are rich in tobacco leaves, and the cigarette industry only uses high-quality tobacco leaves as raw materials, about 22%-30%. Secondary tobacco leaves, tobacco stems, and tobacco dust are discarded as waste, which not only causes waste of resources but also pollutes the environment

At present, in the comprehensive utilization of tobacco residues, industrial methods are used to extract nicotine and then made into pesticides or other industrial raw materials. The process is complicated and the investment is huge. However, the special fertilizer for peanut insecticide is directly made from tobacco residues, which has a simple process and less investment. , the field insecticidal effect is better, and the effect of increasing production and income is remarkable
