Embodiment 1

[0037] Embodiment 1 The preparation of organic composite matrix 1

[0038] (1) Preparation and treatment of residues from biohydrocarbon engineering: separate the residue and fermentation liquid from corn straw fermented and decomposed in the hydrogen production stage of biohydrocarbon engineering; air-dry and pulverize the separated fermentation residue for later use .

[0039] The weight range of each component in the treated fermentation residue is 70-76 parts of organic matter, 25-30 parts of humic acid, 44-49 parts of total carbon, 0.8-1.5 parts of total nitrogen, 0.5-1.0 parts of total phosphorus, and 0.5 parts of total potassium ~1.0 parts, total calcium 0.15~0.23 parts, total magnesium 0.05~0.1 parts, C / N is 45~55, and also contains rich trace elements such as iron, manganese, zinc, copper, boron and molybdenum. The content of heavy metal elements cadmium, chromium, lead, mercury and arsenic is within the safe use range, which meets the requirements of NY525-2011 "Org...

Embodiment 2

[0042] Example 2 Preparation of Organic Composite Matrix 1

[0043] (1) Preparation and treatment of biohydroane engineering residue: same as in Example 1.

[0044] (2) Preparation of organic composite matrix: the steps are the same as in Example 1, except that the volume ratio of fermentation residue to peat, vermiculite and perlite is 0.6:1.4:1:1.

[0045] When in use, the organic composite substrate is introduced into the seedling raising tray of the seedbed, sprayed with water, and the seeds can be directly sown.

Embodiment 3

[0046] Example 3 Preparation of Organic Composite Matrix 1

[0047] (1) Preparation and treatment of biohydroane engineering residue: same as in Example 1.

[0048] (2) Preparation of organic composite matrix: the steps are the same as in Example 1, except that the volume ratio of fermentation residue to peat, vermiculite and perlite is 0.7:1.3:1:1.

[0049] When in use, the organic composite substrate is introduced into the seedling raising tray of the seedbed, sprayed with water, and the seeds can be directly sown.

Abstract

The invention discloses an organic composite substrate for oilseed rape tray-soilless seedling and a preparation method of the organic composite substrate, and belongs to the technical field of agricultural cultivation. The organic composite substrate comprises turf, vermiculite, perlite and biological hydrogen alkane engineering fermentation residues. According to the substrate, the biological hydrogen alkane engineering fermentation residues replace a common substrate formula so that residue waste can be recycled, and the substrate is safe, nutrient and high in practicability. The preparation method is easy to operate and low in cost. The invention further provides the application of the biological hydrogen alkane engineering fermentation residues in the organic composite substrate for oilseed rape tray-soilless seedling, an effective way is provided for treatment of the residues, and the comprehensive benefits of the biological hydrogen alkane engineering are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to an organic composite matrix for raising rape seedlings in plug trays and a preparation method thereof. Background technique [0002] In recent years, the excessive use of chemical fertilizers and pesticides and heavy metal pollution in soil and irrigation water have seriously affected the quality and yield of vegetables in my country. The production of pollution-free vegetables and the guarantee of organic green cultivation of vegetables have become an urgent need. With the rapid development of modern facility agriculture, the cultivation area of ​​facility vegetables in our country is expanding year by year. It can effectively reduce the amount of chemical fertilizer used in vegetable cultivation, reduce pesticide pollution, and avoid the impact of soil heavy metal pollution on vegetable production. As an important application of soilless cultivatio...
