Embodiment 1

[0035] Prepare trichloroisocyanuric acid+pyrethrum root, stem and leaf dry powder organic fertilizer according to the mass ratio of 1:1, the ratio of each component of the organic fertilizer is:

[0036] Trichloroisocyanuric acid: dry powder of pyrethrum root, stem and leaf = 1:1.

[0037] Its preparation method comprises the following steps:

[0038] (1) Preparation of dry powder of pyrethrum roots, stems and leaves

[0039] Pyrethrum roots, stems, and leaves are dried in the sun, then dried at 50°C, and then pulverized to obtain pyrethrum root, stem, and leaf dry powder.

[0040] (2) Sieve

[0041] Pass the obtained dried pyrethrum root, stem and leaf powder through sieves of 10 mesh, 20 mesh, 40 mesh, 80 mesh and 120 mesh respectively to obtain five kinds of dry powder of pyrethrum root, stem and leaf with different particle sizes.

[0042] (3) According to the mass ratio of trichloroisocyanuric acid: dry powder of pyrethrum roots, stems and leaves = 1:1, slowly mix tric...

Embodiment 2

[0047]Prepare trichloroisocyanuric acid+pyrethrum root, stem and leaf dry powder organic fertilizer at a mass ratio of 1:5, the ratio of each component of the organic fertilizer is:

[0048] Trichloroisocyanuric acid: dry powder of pyrethrum roots, stems and leaves = 1:5.

[0049] Its preparation method is the same as that of Example 1, except that the proportions of each component are changed, so no repeated description is given here.

[0050] Chlorobromoisocyanuric acid + pyrethrum roots, stems and leaves dry powder organic fertilizer is obtained by replacing the trichloroisocyanuric acid in this example with chlorobromoisocyanuric acid.

Embodiment 3

[0052] Prepare trichloroisocyanuric acid+pyrethrum root, stem and leaf dry powder organic fertilizer according to the mass ratio of 1:20, the ratio of each component of the organic fertilizer is:

[0053] Trichloroisocyanuric acid: dry powder of pyrethrum roots, stems and leaves = 1:20.

[0054] Its preparation method is the same as that of Example 1, except that the proportions of each component are changed, so no repeated description is given here.

[0055] Chlorobromoisocyanuric acid + pyrethrum roots, stems and leaves dry powder organic fertilizer is obtained by replacing the trichloroisocyanuric acid in this example with chlorobromoisocyanuric acid.

Abstract

The invention provides an organic fertilizer which comprises a first component and a second component which have the mass ratio of 1: 1 to 900, wherein the first component is trichloroisocyanuric acid and / or chlorobromoisocyanaria acid, and the second compound is the dry residue pest-control chrysanthemum powder and / or dry pest-control chrysanthemum stem leaf powder. With the adoption of the organic fertilizer, the preparation method of the organic fertilizer and the method for controlling the soil borne disease provided by the invention, the defects that the soil borne disease controlling effect of the dry pest-control chrysanthemum stem leaf powder or the dry residue pest-control chrysanthemum powder is reduced or the effect of the fertilizer is slowly implemented after the dry pest-control chrysanthemum stem leaf powder or the dry residue pest-control chrysanthemum powder is directly applied to the farmland system or is applied to the farmland system after being matured can be overcome; the fertility of the soil can be obviously improved; the output of the crops can be greatly increased; and meanwhile, obvious effect of pest control and sterilizing can be achieved.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to an organic fertilizer with insecticidal and bactericidal functions. Background technique [0002] Soil-borne diseases are plant diseases caused by the infection of soil-borne pathogens, which belong to the category of root diseases. Infection pathogens include fungi, bacteria, actinomycetes, and nematodes. Soil-borne diseases and insect pests have always been an important factor affecting agricultural production. [0003] In recent years, many vegetable fields have lost production due to soil-borne diseases, especially vegetable physiological diseases, which have become more and more serious year by year. The main reason is that the pathogenic microorganisms in the soil accumulate year by year, which gradually aggravates soil-borne diseases and insect pests; the same crop is planted in the same plot for many years, resulting in the lack or imbalance of the nutrient elements preferred by...
