Problems solved by technology

[0007] However, these organic fertilizers are all fermented and mixed with inorganic fertilizers, which can only solve the problems of land compaction and salinization. So far, there is no organic fertilizer that can effectively inhibit or kill soil-borne pests.

Embodiment 1

[0049] Concrete steps and process conditions of the preparation process of the present invention are as follows:

[0050](1) Take 75% of cow dung with a moisture content of 70% (percentage by weight, the same below), 7% of porous peat, 10% of straw powder, and 8% of distiller's grains and mix them in proportion, adjust with urea, ammonium bicarbonate, lime nitrogen, etc. The C / N (mass ratio) of the compost material is 30:1, and the organic matter content of the compost material is adjusted to 60%. Then the compost material is transferred into a compost reactor, and 0.25% of VT-100 bacterial agent and 0.25% of VT-1000 bacterial agent are added to the total weight of the compost material. When the composting temperature rises to 50°C, the composting begins to be turned over every 5 days, and the cow dung fermentation product is formed after 15 days of composting.

[0051] (2) The crushed plant material is obtained by crushing the leaves and branches of the neem tree, and the bo...

Embodiment 2

[0053] (1) Take 60% of cow dung with a moisture content of 70% (percentage by weight, the same below), 5% of porous peat, and 10% of straw powder and mix them in proportion, and use urea to adjust the compost material C / N (mass ratio) to 30 : 1, the organic matter content of the compost material is adjusted to 45%. Then the compost material is transferred to a compost reactor, and 0.5% of the total weight of the compost material is added with an enzyme bacteria quick-rot agent. When the composting temperature rises to 50°C, the composting begins to be turned over every 5 days, and the cow dung fermentation product is formed after 10 days of composting.

[0054] (2) The crushed plant material is obtained from the leaves and branches of edamame, neem tree and neem tree, and the bone powder is obtained by crushing dried bovine bones, sheep bones and fish bones and passing through a 40-mesh sieve. Weigh 62% of the cow dung fermentation product, 8% of the crushed plants, and 30% o...

Embodiment 3

[0056] Concrete steps and process conditions of the preparation process of the present invention are as follows:

[0057] (1) Take cow dung 60% (percentage by weight, the same below) with a moisture content of 85%, porous peat moss 25%, straw powder 5%, distiller's grains 8%, beer dregs 2% and mix in proportion, and use urea, ammonium bicarbonate Adjust the C / N (mass ratio) of the compost material to 25:1, adjust the organic matter content of the compost material to 45%, and then transfer the compost material to the compost reactor. Add VT-100 bacterial agent accounting for 5% of the total weight of the compost material. When the compost temperature rises to 60°C, the compost starts to be turned over every 3 days, and the cow dung fermentation product is formed after 10 days of composting.

[0058] (2) The crushed plant material is obtained from the leaves and branches of edamame, neem tree and neem tree, and the bone powder is obtained by crushing dried fish bones and passin...

Abstract

The invention relates to an ecotype type organic fertilizer and a preparation method thereof. The method is characterized in that the ecotype type organic fertilizer is formed by dairy manure leavening, a plant crushing material and bone meal through crushing, even mixing and secondary fermentation. The ecotype type organic fertilizer comprises the following formula in weight percentage: 50 to 75 percent of the dairy manure leavening, 8 to 25 percent of the plant crushing material and 12 to 30 percent of the bone meal. The organic fertilizer can effectively inhibit or kill underground pests and pest eggs, cultivate soil fertility, lighten secondary salinization of the vegetable field, in particular the old vegetable field, promote the restoration of ecological balance of the vegetable field and substantially reduce the usage of pesticide and fertilizer in the vegetable field .

Description

technical field [0001] The invention relates to an ecological organic fertilizer, in particular to an ecological organic fertilizer which is obtained by pulverizing fermented cow dung, crushed plants and bone powder and uniformly mixing them for secondary fermentation. Background technique [0002] For vegetable soil with a high multiple cropping index, due to partial application and excessive application of chemical fertilizers, problems of soil fertility decline, soil-borne pests intensification, and soil secondary salinization often occur, resulting in reduced yields, reduced harvests, or even no harvests. The damage of soil-borne diseases is becoming more and more serious, and has become the main factor restricting the development of vegetable production in protected areas. Especially in some old vegetable areas, the disease is extremely serious, and some areas have developed to the extent that no longer can be produced. For a long time, the control of soil-borne disease...
