Problems solved by technology

The properties of these substrates are relatively stable, and the cultivation effect is relatively good, but salt cotton and pearl salt are difficult to degrade in nature, which is easy to cause environmental pollution
However, peat is a limited natural resource, and large-scale exploitation will cause damage to the natural environment.
[0005] Vegetable and Flower Research Institute of Chinese Academy of Agricultural Sciences has successfully developed organic ecological soilless cultivation technology in recent years, and developed several composite substrates, such as peat: slag = 4:6, sand: coconut shell = 5:5, sunflower straw: slag : sawdust = 5: 2: 3, peat: pearl salt = 7: 3, etc. These substrates generally contain inorganic components, which do not belong to organic composite substrates and cannot be used in organic soilless cultivation

specific Embodiment approach

[0022] Four, the specific implementation method: 1, embodiment 1:

[0023] Mushroom dregs 50%, peat 50%.

[0024] Preparation method: Ferment the dregs of edible mushrooms that have just been cultivated with conventional microbial strains for 20 to 120 days (depending on the ambient temperature), until the temperature does not rise and the fermentation is complete. Take 0.5 cubic meters of fermented mushroom dregs and mix them with 0.5 cubic meters of peat.

[0025] Cucumbers were grown and the control was 100% perlite. The output is as follows: the yield of cucumbers grown on organic composite substrates is 5994 kg / mu, and the yield of cucumbers grown on perlite is 2682 kg / mu, an increase of 123%. 2. Embodiment 2:

Embodiment 2

[0026] In the formula, there are 50% mushroom dregs and 50% sawdust.

[0027] The preparation method is the same as before.

[0028] Cucumbers were planted, and the contrast was 100% perlite, and the yields were as follows: the yield of cucumbers planted with organic composite substrates was 5418 kg / mu, and the yield of cucumbers planted with perlite was 2682 kg / mu, an increase of 102%. 3. Embodiment 3:

Embodiment 3

[0029] In the formula, mushroom dregs are 50% and planed dregs are 50%.

[0030] The preparation method is the same as before.

[0031] Cucumbers were planted, and the contrast was 100% perlite, and the output was as follows: the yield of cucumbers planted with organic composite substrates was 5220 kg / mu, and the yield of cucumbers planted with perlite was 2682 kg / mu, an increase of 95%. 4. Embodiment 4:

Abstract

The composite organic substrate for the soilless culture of vegetables, stapling, melon, fruit tree, etc is prepared from the residual dregs and one of shavings, saw dust and peat, all of which are the waste generated after culturing mushrooms, through fermenting and proportional mixing. Its advantages are low cost, and high yield of crops.

Description

1. Technical field: [0001] The invention relates to a plant cultivation technology, in particular discloses an organic composite substrate and a preparation method thereof, which are mainly used for soilless cultivation of vegetables, fruits, flowers and seedlings. 2. Background technology: [0002] As an important technology for high-quality and high-yield vegetables, soilless cultivation has developed very fast in developed countries in the world, especially in Europe. In 1995, the soilless cultivation area in the Netherlands was 5110 hectares, accounting for 51% of the total greenhouse area; the soilless cultivation area in Turkey was 1030 hectares, accounting for 46% of the total greenhouse area; the soilless cultivation area in France was 983 hectares, accounting for 51% of the total greenhouse area. 36% of the total; Japan's soilless cultivation area is 760 hectares, accounting for 1-2% of the total greenhouse area. At present, the soilless cultivation area in the abo...
