Description

Technical Field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer for promoting the development of tobacco roots. Background Art

[0002] Tobacco is an important cash crop in my country, primarily grown in provinces like Yunnan and Guizhou, and plays a crucial role in the national economy. A well-developed root system helps tobacco plants quickly absorb nutrients from the soil and improve their resilience to stress.

[0003] Currently, rooting powders are commonly used on the market to promote root growth in crops. The main ingredients of common rooting powders are chemical components such as indoleacetic acid, indolebutyric acid, naphthaleneacetic acid, and gibberellins. They mainly achieve the purpose of rooting by stimulating the formation of endogenous plant hormones, so they are also called "plant stimulants." This type of substance promotes rooting quickly, but there are problems with it, such as insufficient nutrition in the later stages of the crop and weak root systems. Long-term use will lead to resistance, and the drug effect lasts for a short period of time. The concentration range used is narrow, and too low or too high will have a significant impact on the plant. It is not suitable for repeated use and has no other effects besides rooting, with a single function. Although there are fertilizers related to microorganisms on the current market, most of them are relatively simple and have limited effect on promoting tobacco production. Summary of the Invention

[0004] The purpose of the present invention is to provide a fertilizer for promoting the development of tobacco root system.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, a fertilizer for promoting the development of tobacco roots is composed of the following raw materials per kilogram of fertilizer: 250-280g of enzyme bacteria, 160-180g of photosynthetic bacteria, 60-70g of phosphate-dissolving and potassium-dissolving bacteria, 60-70g of boric acid, 120-130g of polyamino acids, 110-130g of potassium dihydrogen phosphate, 100-110g of brassinolide, and the balance is zinc sulfate.

[0011] The preparation method of the above fertilizer is to mix various raw materials evenly.

[0012] Preferably, the method for using the fertilizer for promoting root development of tobacco is as follows: each kilogram of fertilizer is mixed with 50L of water and sprayed on the front leaves and roots of the tobacco plants; 1kg of fertilizer is used per mu of land.

[0013] The present invention uses a variety of microbial preparations and chemical substances for mixing and compounding. The enzyme bacteria in the microbial preparations can decompose toxic substances in fertilizers and pesticides into non-toxic substances, enhance plant metabolic function, improve photosynthesis, promote seed germination, develop plant root systems, enhance retrograde resistance, and increase yields; photosynthetic bacteria can improve the photosynthetic efficiency of leaves and enhance root vitality; phosphate-dissolving and potassium-dissolving bacteria can decompose insoluble silicate minerals in the soil, releasing silicon, phosphorus, potassium and other elements therein, thereby increasing soil fertility and promoting crop growth; boric acid in the chemical substances can promote the normal growth of crop root tips and stem growth points and other meristems, promote crop root development, and also form peroxides with alcohols, sugars and other compounds, thereby improving the oxygen supply to crop roots and further promoting root growth; polyamino acids, potassium dihydrogen phosphate, brassinolide and zinc sulfate can further supplement the nutrients required for tobacco growth and promote tobacco growth and development. The invention has a reasonable composition, and the addition of microbial preparations reduces the use of chemical substances. The effect lasts for a long time, does not produce resistance, and is suitable for multiple uses. It can not only promote the growth and development of tobacco roots, but also promote tobacco photosynthesis. At the same time, it also has a certain repair function for the soil. It has diverse functions and greatly improves the stress resistance of tobacco. DETAILED DESCRIPTION
