Special ecological carbon-based fertilizer for tobacco

Abstract

The invention provides a special ecological carbon-based fertilizer for tobacco. The special ecological carbon-based fertilizer for tobacco is prepared by mixing charcoal produced from tobacco waste such as tobacco stems, waste tobacco leaves and tobacco flowers and wood vinegar with melia azedarach seeds, artemisia annua, scandent hop, euphorbia lunulata, folium artemisiae argyi and other animal and plant organic matter raw materials. The special ecological carbon-based fertilizer for tobacco is capable of improving and remediating the ecological health of the soil, supplementing soil nutrients, improving the water/fertility retention capability of the soil and fertilizing the soil, and further capable of preventing the plant diseases and insect pests of the tobacco, reducing the pesticide residual and the heavy metal residual quantity in tobacco leaves; in short, the fertilizer is capable of achieving multiple functions, effectively improving the quality and the yield of the tobacco leaves and increasing the tobacco planting benefit; the input-output ratio reaches 1: 5; due to the application of the special ecological carbon-based fertilizer for tobacco, the pollution of the tobacco waste on the environment can be effectively reduced, and meanwhile, the tobacco waste is transformed into the charcoal containing more than 60% of fixed carbon and applied back to the tobacco field, and equivalently, carbon dioxide in the atmosphere is captured and reserved in the soil; as a result, net decrease of carbon dioxide in the atmosphere can be realized and the environment can be protected.

Description

technical field [0001] The invention relates to a tobacco-specific fertilizer, in particular to a tobacco-specific ecological carbon-based fertilizer. Background technique [0002] In recent years, with the extensive use of chemical fertilizers and pesticides and continuous cropping of tobacco planting, soil ecological damage has been caused, carbon-nitrogen ratio imbalance, soil-borne diseases and insect pests have been aggravated, and the use of pesticides has increased, resulting in increased tobacco residues and heavy metal residues. The quality and planting income have declined; the random discarding of tobacco field waste such as tobacco stems, tobacco branches, waste tobacco leaves, and fireworks has caused pollution to the environment, and has also increased the source of disease and insect sources in the tobacco field, forming cumulative damage. In response to the above problems, the technical methods currently adopted are: (1) increase the amount of organic fertil...

Problems solved by technology

[0002] In recent years, with the extensive use of chemical fertilizers and pesticides and continuous cropping of tobacco planting, soil ecological damage has been caused, carbon-nitrogen ratio imbalance, soil-borne diseases and insect pests have been aggravated, and the use of pesticides has increased, resulting in increased tobacco residues and heavy metal residues. Decreased quality and planting income; random discarding of tobacco field waste such as tobacco stems, tobacco branches, waste tobacco leaves, fireworks, etc. has caused pollution to the environment, and at the same time increased the source of diseases and insects in the tobacco field, forming a cumulative hazard

In response to the above problems, the technical methods currently adopted are: (1) increase the amount of organic fertilizers used to increase soil organic matter and improve soil structure, but there is a single effect and no persistence; (2) increase the amount of pesticides to prevent pests and diseases, However, there are problems of increasing drug residues in tobacco leaves, reducing the quality of tobacco leaves, and causing cumulative harm caused by long-term use, while the use of biopesticides currently has high input costs and ineffective effects; (3) Shorten the continuous cropping cycle of tobacco and carry out crop rotation, but increase the input cost of crop rotation (4) Tobacco field waste is prohibited from being discarded in the field, but there is no way out to deal with it, and it is finally incinerated randomly to cause pollution. Farmers are also organized to carry out composting treatment, but it is difficult to implement due to the lack of labor in the countryside
