Charcoal-based functional fertilizer capable of preventing cotton continuous cropping disease and preparation method thereof

Abstract

The invention discloses a charcoal-based functional fertilizer capable of preventing cotton continuous cropping disease, which comprises the following components: 95-105 parts of bamboo leaf extract product, 35-46 parts of cordate houttuynia extract product, 45-56 parts of plantago extract product, 35-45 parts of sophora flavescens extract product, 37-47 parts of jasmonic acid, 45-55 parts of salicylic acid and 3700-4150 parts of charcoal. The functional fertilizer is environmentally friendly, has no any pollution and residues, has no side effect, can reduce environment pollution and overcome generation of soil borne disease, is not restricted by continuous cropping plantation, and is benefit for reasonable layout of crops, the continuous cropping-resistant effect is stable after multi-year plantation, fertilization and medication can be carried out at once, labor intensity is reduced, production cost is saved; pesticide application is greatly reduced, crops phytotoxicity and human and animal poisoning are reduced, when booth plantation of vegetable grown in rotation is not carried out, comprehensive effect is obvious, and the functional fertilizer has good continuous cropping prevention effect for cotton.

Description

Technical field [0001] The invention relates to a carbon-based functional fertilizer, in particular to a carbon-based functional fertilizer for preventing cotton stubble disease and a preparation method thereof, and belongs to the technical field of agriculture. Background technique [0002] Certain crops, such as legumes, melons, vegetables, strawberries and some Chinese herbal medicines and other cash crops that have been planted on the same field for many years, wilt, leaf blight, and virus diseases often occur, causing crop yellowing and sporadic seedlings , Even a large number of plants die, which seriously affects the improvement of yield and quality. This phenomenon is called continuous cropping obstacle in cultivation science. Yellow wilt is prone to appear after continuous cropping of cotton, resulting in lower yields. [0003] The main reasons for continuous cropping obstacles are as follows: [0004] ①Increase the breeding and reproduction of pathogenic microorganisms, p...

[0005] ② Affect the physical and chemical properties of the soil and reduce the fertilizer efficiency;

[0006] ③ Accelerate the consumption of certain nutrients, resulting in nutrient loss;

[0010] In the process of realizing the present invention, the inventor has found that the prior art has at least the following deficiencies: although the implementation of crop rotation has a good effect in overcoming the disadvantages caused by continuous cropping, it is difficult to realize this mode of continuous cropping due to the constraints of land area and other factors, especially In the cultivation of vegetables in greenhouses in the north, it is even more difficult to achieve crop rotation

[0011] In addition, there are many kinds of germs in the soil. Under different soil conditions, the growth of microorganisms is obviously affected by the soil conditions, resulting in unstable and unsatisfactory effects on inhibiting germs.
