Embodiment 1

[0021] The production of the used organic fertilizer of embodiment 1 plant cultivation substrate of the present invention

[0022] The chicken manure of layer hens of Beijing Deqingyuan Company has undergone mesophilic anaerobic fermentation and aerobic fermentation, specifically:

[0023] Firstly, the laying hen manure is subjected to medium-temperature anaerobic fermentation, then the chicken manure is put into a completely anaerobic fermenter, and the acidifying bacteria group (generally, the strains that can be fermented anaerobically can be used) is used for fermentation. The fermentation time is 20 days. (The fermentation time is 10-20 minutes, depending on the biogas production), and the fermentation temperature is 38°C. The main purpose of mesophilic anaerobic fermentation is to produce biogas, which can be used for power generation or purified into natural gas. What the present invention utilizes is the by-product biogas residue produced in this process.

Embodiment 2

[0026] Embodiment 2 The production of eggshell powder used in plant cultivation substrate of the present invention

[0027] The eggshell is washed to remove the remaining egg white, dried, and ground into a powder with a particle size of 0.3-1.0 mm, namely the eggshell powder.

Embodiment 3

[0028] Embodiment 3 The preparation of plant cultivation substrate of the present invention

[0029] Plant cultivation substrate preparation ratio of the present invention is:

[0030] (1) Measure 10L eggshell powder

[0031] (2) Measure 10L of organic fertilizer

[0032] (3) Measure 35L of long-rotten peat

[0033] (4) Measure 45L of vermiculite

[0034] The above-mentioned long-rot peat, vermiculite, and special fertilizer sources are fully stirred and mixed evenly, and prepared into a plant cultivation substrate. For the preparation method of the eggshell powder, see Example 2, and for the preparation method of the organic fertilizer, see Example 1 for the eggshell powder. The long-rot peat and vermiculite used are commercially available.

Abstract

The invention provides a plant cultivation medium. The plant cultivation medium is prepared by the following components, by volume percentage, 10 to 15 % of eggshell powder, 10 to 15 % of organic fertilizer, 25 to 35 % of grass carbon and 45 to 55 % of vermiculite. The invention also provides a preparation method and applications of the plant cultivation medium. The preparation method of the plant cultivation medium is low in artificial feed preparation cost, simple in operation and strong in practicability. The plant cultivation medium has the advantages of being rich in nutrient element such as nitrogen, phosphorus, potassium, calcium and magnesium, providing nutrients for plants required for growing at all stages, enabling seeds to rapidly sprout and root; being good in heat preservation and moisture preservation performance and applied to root protection covering, effectively improving the plant diseases and insect pests resistant capability and enabling the plants to grow healthily and rapidly due to the fact that the chicken manure fermented organic fertilizer contains biological bacteria floras; enabling poultry cultivation rubbish to be processed in a batch and providing a path for reducing emission and generating income of culture industries.

Description

technical field [0001] The invention belongs to the field of plant planting, and in particular relates to a plant planting substrate and its preparation method and application. Background technique [0002] Since the 1990s, my country's protected cultivation agriculture has developed rapidly, and it has now exceeded 2.6 million hectares, becoming a pillar industry in my country's rural areas. The rapid development of modern protected cultivation has made the accumulation of harmful organisms in the soil, the imbalance of nutrient elements, the obstacles to continuous cropping and the secondary salinization of the soil increasingly prominent. The use of matrix cultivation is the most effective, economical and thorough way to overcome continuous cropping obstacles and accumulation of harmful organisms in the soil, and to ensure the health of crops. Since the early 1990s, my country has started to promote the technology of organic ecological cultivation substrates. [0003] T...
