Problems solved by technology

Specifically, the long-term and large-scale application of chemical fertilizers destroys the original physical and chemical properties of the soil, leading to soil acidification, soil bulk density reduction, aggregate structure damage, soil permeability reduction, and water and fertilizer retention performance. The application of organic fertilizers has not yet received due attention, resulting in the decrease of soil organic matter, the decrease of soil carbon-nitrogen ratio, the imbalance of soil carbon pool, a

Abstract

The invention provides a special high-carbon based soil remediation fertilizer for tobacco fields and a production method and application method of the special high-carbon based soil remediation fertilizer for the tobacco fields. The special high-carbon based soil remediation fertilizer for the tobacco fields comprises the following components in percentage by weight: 25 to 35% of biochar, 4 to 6% of a cake fertilizer, 1 to 3% of humic acid, 10 to 15% of potassium nitrate, 4 to 6% of medical stone, 30 to 40% of dried cow-dung, 0.5 to 1% of shell powder, 2 to 4% of biological bacteria, 1 to 2% of white stone powder, and the balance of microelement fertilizers. According to the invention, organic materials which are high in carbon and low in nitrogen, loose and porous and high in specific surface area are mainly taken as carriers, a variety of mineral nutrient elements are directionally added, a variety of physiological active materials are combined, and remediation of soil carbon pools and activation of soil microbial communities are taken as purposes, and the micro-ecological environment of tobacco plant roots are coordinated and optimized to promote the root development of tobacco plants, balance the nutrition of the tobacco plants and improve the use efficiency of tobacco plant nutrients.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of tobacco planting, and in particular relates to a special high-carbon-based soil restoration fertilizer for tobacco fields, a production method and an application method thereof. [0003] Background technique: [0004] At present, the chemical fertilizers used in the tobacco planting process are mainly special fertilizers for tobacco planting, or simple compound fertilizers. Due to the long-term and large-scale application of chemical fertilizers in my country's tobacco fields, one-sided pursuit of tobacco leaf production and other phenomena. With the continuation of high fertilization and high-intensity crop rotation system in the tobacco industry, it has caused serious problems such as soil quality degradation, tobacco leaf quality decline, and unremarkable style characteristics. Specifically, the long-term and large-scale application of chemical fertilizers destroys the original physical and chem...
