Embodiment 1

[0034] Prepare trichloroisocyanuric acid+dry vine 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:

[0035] Trichloroisocyanuric acid: dry powder of deer vine stems and leaves = 1:1.

[0036] Its preparation method comprises the following steps:

[0037] (1) Preparation of dry powder of deer vine stems and leaves

[0038] Dried deer cane stems and leaves in the sun, then dried at 50°C, and then pulverized to obtain deer cane stem and leaf dry powder.

[0039] (2) Sieve

[0040] Pass the obtained dried deervine stem and leaf powder through sieves of 10 mesh, 20 mesh, 40 mesh, 80 mesh and 120 mesh respectively to obtain five kinds of dried deervine stem and leaf powders with different particle sizes.

[0041] (3) According to the mass ratio of trichloroisocyanuric acid: dry powder of deervine stems and leaves = 1:1, slowly and repeatedly mix trichloroisocyanuric acid into the five kinds o...

Embodiment 2

[0046] Prepare trichloroisocyanuric acid+dry vine stem and leaf dry powder organic fertilizer according to the mass ratio of 1:5, the ratio of each component of the organic fertilizer is:

[0047] Trichloroisocyanuric acid: dry powder of deer vine stems and leaves = 1:5.

[0048] 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.

[0049] The trichloroisocyanuric acid in this example is replaced by chlorobromoisocyanuric acid to obtain chlorobromoisocyanuric acid + deervine stem and leaf dry powder organic fertilizer.

Embodiment 3

[0051] Prepare trichloroisocyanuric acid+dry vine 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:

[0052] Trichloroisocyanuric acid: dry powder of deer vine stems and leaves = 1:20.

[0053] 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.

[0054] The trichloroisocyanuric acid in this example is replaced by chlorobromoisocyanuric acid to obtain chlorobromoisocyanuric acid + deervine stem and leaf dry powder organic fertilizer.

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 residue dry powder obtained after extracting the derris root and/or dry derris steam 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 derris steam leaf powder or the residue dry powder obtained by extracting the derris root is reduced or the effect of the fertilizer is slowly implemented when the derris steam leaf powder or the residue dry powder obtained by extracting the derris root is directly applied to the farmland system 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 and insect pests, especially soil-borne diseases have always been an important factor affecting agricultural production. Soil-borne diseases refer to plant diseases caused by the infection of soil-borne pathogens, which belong to the category of root diseases. Infection pathogens include fungi, bacteria, actinomycetes, etc., among which fungi are the main ones. More than 100 kinds of diseases found in cultivation that harm melons, solanaceous fruits, beans and other vegetables, most of them are fungal, bacterial diseases and some viral diseases, and the pathogens are all in the soil or with the help of diseased residues Overwinter in the soil. The initial infestation of these diseases almost always comes from the soil. In recent years, due to continuous cropping, heavy...
