Embodiment 1

[0021] Embodiment 1 Vegetable soilless cultivation substrate 1

[0022] 70 parts of coffee shells, 10 parts of rapeseed meal, 10 parts of peat, 10 parts of perlite; 0.003 parts of plant growth regulator.

[0023] The coffee husk and rapeseed meal composting fermentation method is as follows: after the coffee husk and rapeseed meal are mixed evenly, adjust the water content to 50%-60%, pile up a height of 1.0-1.5 meters, and stack retting for 15 days; when the temperature in the center of the fermentation pile exceeds 55℃, turn over Heap, water replenishment, so that the moisture in the fermentation heap maintains more than 50%; repeat the operation until the color of the fermentation heap turns black, and at the same time the temperature of the fermentation heap drops below 40°C, and when the water content is below 40%, the fermentation ends and the decomposed matter is obtained. Add functional bacterial agents for secondary fermentation. After 6 days, when the water content d...

Embodiment 2

[0025] Embodiment 2 Vegetable soilless culture substrate 2

[0026] 50 parts of coffee shell, 15 parts of rapeseed meal, 20 parts of peat, 15 parts of perlite; 0.001 part of plant growth regulator;

[0027] The coffee shell fermentation process is the same as in Example 1. After the fermentation is completed, the product after the secondary fermentation is mixed evenly with peat, perlite, and plant growth regulator in the above ratio to obtain a soilless cultivation substrate for vegetables.

Embodiment 3

[0028] Embodiment 3 Vegetable soilless cultivation substrate 3

[0029] 80 parts of coffee shells, 5 parts of rapeseed meal, 7 parts of peat, 8 parts of perlite; 0.004 parts of plant growth regulator.

[0030] The coffee shell fermentation process is the same as in Example 1. After the fermentation is completed, the product after the secondary fermentation is mixed evenly with peat, perlite, and plant growth regulator in the above ratio to obtain a soilless cultivation substrate for vegetables.

Abstract

The invention provides a soilless culture substrate for vegetables. The substrate contains the following raw materials in parts by weight: 50-82.5 parts of coffee shells, 2.5-15 parts of rapeseed meal, 5-20 parts of turf, 5-15 parts of perlite and 0.001-0.005 part of a plant growth regulator. The preparation method comprises the following steps: uniformly mixing the coffee shells and rapeseed meal, and adding a fermented compound microorganism bacterium agent and a functional bacterium agent for performing secondary fermentation. According to the soilless culture substrate for vegetables, disclosed by the invention, the coffee shells can be well utilized, and pollution of coffee shell wastes is reduced. Meanwhile, the substrate is low in production cost, can achieve the effects of effectively promoting growth of the vegetables, reducing diseases of the vegetables and increasing the yield of the vegetables, is applicable to soilless culture of vegetables or can be used as a vegetable seedling substrate.

Description

technical field [0001] The invention relates to a plant growth substrate, in particular to a vegetable soilless cultivation substrate and application thereof. Background technique [0002] Coffee is one of the three major beverages in the world, and it is widely planted all over the world. In 2015, my country's coffee planting area reached 1.8 million mu. The main by-products of coffee bean production are fresh coffee peel, coffee shell and coffee pulp (in this patent We are collectively referred to as coffee shells), and the by-products can reach more than 560,000 tons per year. Most of the by-products of coffee are discarded, causing a large impact on the environment. At present, coffee by-products are mainly used in animal feed, fertilizer, fuel, cellulose board, etc., but the application of coffee by-products in these aspects has shortcomings. Since coffee by-products contain tannins, the amount added as animal feed cannot exceed 20% of the daily intake. As a fertilize...
