A fertilizer used for killing pests and weeding and a preparation method thereof

Abstract

The invention discloses a fertilizer used for killing pests and weeding. The fertilizer is prepared from following raw materials in parts by weight: 20-25 of weathered coal, 10-14 of river sand, 8-10 of bentonite, 10-13 of tobacco leaf residue and broken pieces, 20-23 of a nitrogen fertilizer, 14-18 of a phosphor fertilizer, 10-15 of a potassium fertilizer, 12-16 of potassium humate, 5-8 of calcium nitrate, 2-3 of citric acid, 1-2 of metsulfuron methyl, 6-9 of cane sugar, 11-15 of a soil conditioner and a proper amount of water. The fertilizer used for killing pests and weeding provides crops with energy and nutrients, increases the utilization rate of the fertilizer, allows the crop yield and quality to be improved, and has functions of killing pests and weeding, and therefore the fertilizer used for killing pests and weeding has many functions and high efficacy. The added metsulfuron methyl can effectively control growth of a plurality of weeds. The tobacco leaf residue and broken pieces contains a large quantity of vitamins and has a good pest killing effect. The potassium humate is an efficient organic potassium fertilizer, is capable of increasing the content of soil available potassium, reducing potassium loss and immobilization and increasing the adsorption rate and the utilization rate of the potassium by the crops, and has functions of conditioning the soil, promoting the crop growth, enhancing the anti-adversity ability of the crops, improving the crop quality, protecting the agroecological environment, and the like. In addition, the added soil conditioner can effectively improve the soil physical and chemical properties and soil nutrient conditions and can promote nutrient adsorption and water adsorption of the plants, and has positive influence on soil microorganisms.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for killing insects and weeds and a preparation method thereof. Background technique [0002] At present, my country's agriculture is developing rapidly. my country is not only a big agricultural country, but also a big country in the use of fertilizers. The application and development of fertilizers are getting more and more attention. In order to meet the needs of the development of agricultural modernization, the production of fertilizers is developing in the direction of diversification such as high-efficiency compound fertilizers and multi-functional fertilizers. The use of insecticidal and weeding fertilizers can make the fertilization of crops and the prevention and control of diseases, insect pests and weeds one-time It can save a lot of labor and improve efficiency, but if the fertilizer is not properly matched, it will not only reduce the fertility of ...
