Problems solved by technology

[0003] China is a large tobacco country, and the output of tobacco leaves and cigarettes ranks first in the world. As a by-product of tobacco, there are not many ways to utilize tobacco straw resources at this stage, and the conditions for industrialization have not yet been formed. There are low technological content, low level of comprehensive utilization, and additional The problems of low value and short industrial chain not only cause a lot of waste of resources, but also cause environmental pollution
The problems caused by improper disposal of tobacco straw are more serious. For example, open burning will waste resources, damage soil fertility, pollute the atmosphere, and affect traffic. Natural decomposition will cause accumulation of toxic substances in the soil, loss of soil nutrients, and spread of diseases and insect pests.
The tobacco stalk problem has existed for a long time and cannot be solved, becoming a big problem that needs to be solved urgently

Embodiment 1

[0044] The consumption of each component in the embodiment 1 of table 1

[0045] components

[0046] First crush the tobacco stalks into small pieces of 3-5cm, then take 1000kg of crushed tobacco stalks and 30kg of cow dung, mix them with a mixer, then add 10Kg of urea and 3Kg of high-efficiency microbial compound bacterial agents (the composition of the compound bacterial agents is mainly cellulose decomposition Bacteria, starch-decomposing bacteria, protein-decomposing bacteria, provided by Anhui Feitian Organic Fertilizer Engineering Technology Research Co., Ltd.) Stir evenly, add appropriate amount of water (about 300Kg) to adjust the appropriate humidity (60% ~ 70%) and pH (pH = 7.0), make a fermentation stack with a width of about 2.5 meters, a height of about 1.2 meters, and an unlimited length with a flattened top. The outer cover is covered with a black plastic film, and the mixed material is naturally fermented. Turn over once every 3 to 4 days with a turnin...

Embodiment 2

[0048] The consumption of each component in the embodiment 2 of table 2

[0049] components

[0050] First crush the tobacco stalks into small pieces of 3-5cm, then take 1000kg of crushed tobacco stalks and 30kg of cow dung, mix them with a mixer, then add 6Kg of urea and 4Kg of high-efficiency microbial compound bacterial agents (composite bacterial agents are mainly composed of cellulose decomposition bacteria, starch-decomposing bacteria, and protein-decomposing bacteria, provided by Anhui Feitian Organic Fertilizer Engineering Technology Research Co., Ltd.) and stirred evenly, and the rest of the process was the same as Example 1 to make tobacco straw compost. Tobacco straw compost, humic acid, and saline-alkali improvement conditioner were mixed according to the dosage in Table 2, and put into a granulator to make granules to make "organic fertilizer for salt suppression and subterranean pest killing in coastal saline soil" granules, which were packaged and shipp...

Embodiment 3

[0052] The consumption of each component in the embodiment 3 of table 3

[0053] components

[0054] Firstly crush the tobacco stalks into small pieces of 3-5cm, then take 1000kg of crushed tobacco stalks and 30kg of cow dung, mix them with a mixer, then add 5Kg of urea and 5Kg of high-efficiency microbial compound bacterial agents (composite bacterial agents are mainly composed of cellulose decomposition bacteria, starch-decomposing bacteria, and protein-decomposing bacteria, provided by Anhui Feitian Organic Fertilizer Engineering Technology Research Co., Ltd.) and stirred evenly, and the rest of the process was the same as Example 1 to make tobacco straw compost. Tobacco straw compost, humic acid, and saline-alkali improvement conditioner were mixed according to the dosage in Table 3, and put into a granulator to granulate and form into granules of "organic fertilizer for salt suppression and subterranean pest killing in coastal saline soil" and packed for delivery...

Abstract

The invention discloses an organic fertilizer for controlling soil salinization of coastal saline soil and killing underground insects and a preparation method thereof. The organic fertilizer provided by the invention comprises, by weight, 300-500 parts of straw compost, 300-500 parts of humic acid and 100-200 parts of a saline-alkali modifier, wherein the straw compost is composed of tobacco straw, livestock and poultry night soil, high-efficiency composite microbial inoculants and urea; and the saline-alkali modifier is composed of gypsum and an attapulgite powder. The organic fertilizer can be used to raise the fertilizer conservation and water retention capability of soil, prolong fertilizer efficiency and supplement beneficial bacteria in soil. With the application of the organic fertilizer, the harm of underground insects in field can be obviously reduced, underground insects are effectively killed, chemical agent amount is reduced, work and cost are saved, and toxicity and side-effect residual quantity of chemical control is reduced. In addition, after the application of the organic fertilizer, the topsoil of coastal saline soil is loosened, unit weight is decreased and the organic carbon content is increased.

Description

technical field [0001] The invention relates to an organic fertilizer for suppressing salt and killing underground pests in coastal saline soil and a preparation method thereof. Background technique [0002] Soil salinization is a global problem that affects the sustainable development of agriculture and the ecological environment. According to statistics, the area of ​​salinized soil in the world accounts for about 1 / 3 of the earth's land area. In my country, the scale of saline soil is quite large. Among the 100 million hectares of cultivated land, there are about 5.374 million hectares of saline soil, and another 44.088 million hectares of saline-alkali wasteland are distributed in Northwest, North China, Northeast China and coastal areas. Studying special fertilizers for salt-tolerant crops in coastal saline soil is one of the effective measures to control saline soil. It is of great significance to adjust and improve the agricultural ecological environment of coastal s...
