Embodiment 1

[0035] Prepare trichloroisocyanuric acid+tobacco waste dry powder organic fertilizer at a mass ratio of 1:1, the ratio of each component of the organic fertilizer is:

[0036] Trichloroisocyanuric acid: tobacco waste dry powder = 1:1.

[0037] Its preparation method comprises the following steps:

[0038] (1) Preparation of tobacco waste dry powder

[0039] The tobacco waste is dried in the shade, then dried in the sun, then dried at 50° C., and then pulverized to obtain dry tobacco waste powder.

[0040] (2) Sieve

[0041] The obtained tobacco waste dry powder is respectively passed through sieves of 10 mesh, 20 mesh, 40 mesh, 80 mesh and 120 mesh to obtain five kinds of tobacco waste dry powder with different particle sizes.

[0042] (3) According to the mass ratio of trichloroisocyanuric acid:tobacco waste dry powder = 1:1, trichloroisocyanuric acid was slowly mixed into the five kinds of tobacco waste dry powder obtained in step (2) in small amounts several times, Fina...

Embodiment 2

[0047]Prepare trichloroisocyanuric acid+tobacco waste dry powder organic fertilizer in a mass ratio of 1:5, the ratio of each component of the organic fertilizer is:

[0048] Trichloroisocyanuric acid: tobacco waste dry powder = 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 + tobacco waste dry powder organic fertilizer was obtained by replacing trichloroisocyanuric acid in this example with chlorobromoisocyanuric acid.

Embodiment 3

[0052] Prepare trichloroisocyanuric acid+tobacco waste dry powder organic fertilizer at a mass ratio of 1:20, the ratio of each component of the organic fertilizer is:

[0053] Trichloroisocyanuric acid: tobacco waste dry powder = 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 + tobacco waste dry powder organic fertilizer was obtained by replacing trichloroisocyanuric acid in this example with chlorobromoisocyanuric acid.

Abstract

The invention provides organic fertilizer which comprises a first component and a second component. The weight ratio of the first component to the second component is 1:1-900, wherein the first component is trichloroisocyanuric acid and / or chloroisobromine cyanuric acid, and the second component is residual dry powder extracted from tobacco and / or tobacco waste dry powder. The defect of attenuated poisonous effect or slow releasing of fertilizer efficiency caused when the tobacco waste dry powder or dry powder extracted from tobacco is used for a farmland system directly or after rotted is overcome, soil fertility can be increased remarkably, crop yield is increased greatly, and the organic fertilizer has evident pest killing and sterilization effects.

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...
