Problems solved by technology

The activated carbon filter cylinder on the gas mask must be closed immediately after use. If the suction filter effect is found to be poor, it must be replaced immediately
[0006] The cumbersome operating procedures and high-risk hidden dangers are enough to scare away farmers' enthusiasm for using drugs
Ordinary farmers farming are generally unwilling to find these troubles

Embodiment

[0037] Example: Manufacture one ton of fertilizer for soil disinfection and prevention of heavy cropping disease.

[0038] 1. Material preparation: 850 kg of compound fertilizer produced by Liaoning Dashiqiao Jinda Fertilizer Industry Co., Ltd., 30 kg of 99.5% chloropicrin liquid produced by Liaoning Dalian Lvfeng Chemical Co., Ltd., 75 kg of 1-2mm activated carbon, 0.5- 1mm zeolite 45 kg.

[0039] 2. Activation: Put the activated carbon and zeolite into the activation tank respectively for activation treatment, the conventional steam activation time is 1 hour, transfer to a drying oven to dry to less than 6% of the water content, and seal it for storage.

[0040] 3. Vaporization: Put the chloropicrin stock solution into the vaporization tank for vaporization, and the vaporization temperature is 80°C to 100°C.

[0041] 4. Adsorption: The activated carbon and zeolite are loaded into the adsorption tower. 10cm thickness spread out. The chloropicrin vapor enters the adsorption...

Abstract

The present invention relates to a fertilizer capable of disinfecting soil for preventing a replant disease, and a manufacturing method thereof. The raw materials of the invention are active carbon and zeolite, which absorb chloropicrin, and manure. The materials are made by a scientific method according to a certain proportion to produce a novel fertilizer which takes the prior practice of basal dressing during crop planting and disinfects the soil while fertilizing, thereby not only performing the disinsection and sterilization of the chloropicrin, but also simplifying the application of the chloropicrin and eliminating the potential risk of chloropicrinism. The method enables farmers to use chloropicrin to prevent the replant disease of crop conveniently and safely while achieving the aim of increasing yield and harvest. After the soil disinfection, no harmful residue is left in the soil and the crop, and thus the method can be used for producing harmless agricultural products.

Description

technical field [0001] The invention relates to a fertilizer for soil disinfection and prevention of repeated cropping disease, which belongs to the technical field of agricultural means of production, and is specifically a new type of fertilizer. technical background [0002] Planting the same crop year after year on the same piece of land often leads to the occurrence of plant diseases such as Fusarium wilt, Verticillium wilt, root rot, nematode disease, and rot. These diseases are collectively referred to as "cropping diseases" in crop cultivation. Due to the limitation of land resources and the influence of the market price of certain crop varieties, the phenomenon of repeated cropping of crops with good market sales and high prices is very common. In addition, the high-density planting of greenhouses in protected areas has led to the increasing damage of "repeated cropping disease" in recent years. more serious. This soil-borne disease has become an impediment to the ...
