Fertilizer for inhibiting soil-borne diseases of potatoes as well as preparation method and application of fertilizer

Abstract

The invention belongs to the technical field of fertilizers, and particularly discloses a fertilizer for inhibiting soil-borne diseases of potatoes as well as a preparation method and application of the fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 40 to 60 parts of organic fertilizer, 30 to 48 parts of traditional Chinese medicine extract, 20 to 36 parts of compound microbial agent, 25 to 35 parts of humic acid, 20 to 30 parts of monopotassium phosphate, 18 to 25 parts of molybdate and 15 to 20 parts of ammonium polyphosphate. The fertilizer provided by the invention not only can inhibit soil-borne germs, but also can kill potato root-knot nematodes, and prevents the potato root-knot nematodes from damaging potato root systems to aggravate infection of the soil-borne germs.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and specifically discloses a fertilizer for inhibiting soil-borne diseases of potatoes, a preparation method and uses thereof. Background technique [0002] Potato is an annual herb of the nightshade family, and is known as the world's five major food crops along with wheat, rice, corn, and sorghum. Potato tubers contain a lot of starch, which can provide rich calories for the human body, and is rich in protein, amino acids, and a variety of vitamins and minerals. one. [0003] Potato soil-borne diseases are a major class of diseases that affect potato yield. The existing method of suppressing potato soil-borne diseases is to remove germs and harmful organisms in the soil for early prevention and control. However, chemical agents are generally used for soil disinfection. It is easy to remain in the soil and change the soil environment, which is not conducive to the growth of potatoes. In t...

AI Technical Summary

Problems solved by technology

[0003] Potato soil-borne diseases are one of the main diseases that affect potato yield. The existing suppression method of potato soil-borne diseases is early prevention and control by soil disinfection to remove germs and harmful organisms in the soil, but soil disinfection generally uses chemical agents. It is easy to remain in the soil and change the soil environment, which is not conducive to the growth of potatoes

In the existing suppression method, chemical agents are sprayed on the leaves for post-control, but the production cost of this method is high, and there are also problems of soil residue and soil environment change

In addition, potato soil-borne diseases often occur at the same time as root-knot nematodes, and root-knot nematodes can easily cause potato root damage and aggravate the infection of soil-borne disease bacteria. However, the existing agents for inhibiting soil-borne diseases usually only target soil-borne pathogens , not effective against potato root-knot nematodes
