Description

Efficient organic fertilizer for improving disease resistance of crops

Technical Field

The invention relates to an organic fertilizer, in particular to a high-efficiency organic fertilizer for improving the disease resistance of crops.

Background

The growth process of crops can not leave fertilizers and medicaments, and the fertilizers provide nutrients for the growth of the crops; the medicament can be sprayed for prevention before the occurrence of diseases or sprayed for treatment after the occurrence of diseases, and the remedy and treatment method through external intervention not only delays the growth of crops, but also can cause the self to generate drug resistance, thereby being not beneficial to the long-term consideration of crop planting.

At present, fertilizers and medicaments on the market are separately used, the respective functions are single, and crops cannot generate the capability of resisting diseases. Therefore, the market urgently needs a fertilizer which can make crops generate resistance by themselves and does not need to spray a medicament to prevent and control diseases.

Aiming at the defects of the prior art, the invention provides a high-efficiency organic fertilizer for improving the disease resistance of crops.

The invention relates to a high-efficiency organic fertilizer for improving the disease resistance of crops, which is prepared by the following steps:

a. preparing a Chinese herbal medicine extract: taking 1-2 parts of glossy privet fruit, 1-3 parts of eclipta alba, 1-2 parts of schisandra chinensis, 1-3 parts of radix ophiopogonis, 1-3 parts of radix angelicae and 1-3 parts of liquorice, adding 60-100 parts of water, soaking in a container for 1-2 hours, heating to 100 ℃, boiling for 1-3 hours, cooling, filtering, removing impurities, and reserving filtrate;

b. preparing a mixed solution: adding 1-5 parts of free amino acid, 1-2 parts of soybean extract, 1-3 parts of mung bean extract, 1-3 parts of cowpea extract, 1-5 parts of amino-oligosaccharin, 1-2 parts of chelated copper sulfate, 1-3 parts of chelated zinc sulfate, 1-2 parts of chelated calcium and 1-3 parts of chelated iron into the extract prepared in the step a to prepare a mixed solution;

c. preparing an organic fertilizer: heating the mixed solution prepared in the step c to 50-70 ℃, stirring for 5-6 hours, heating to 30-60 ℃ after 1-3 hours, stirring for 3-5 hours, cooling to 25 ℃, and adding 1-3 parts of superoxide dismutase to obtain a finished product;

the parts are parts by weight.

The efficient organic fertilizer for improving the disease resistance of crops, disclosed by the invention, is used for inducing the crops to form antibacterial substances in advance by applying a plant nutrition immunology principle, temporarily storing the antibacterial substances in plant tissues, and activating a pre-stored induction defense system when the plants are infected by pathogenic bacteria so as to achieve the effects of preventing diseases and resisting diseases.
