Problems solved by technology

However, the crop straw C / N used in the production of such substrates (such as corn straw C / N is 104.9, wheat straw C / N is 96.9) is significantly higher than the optimal C / N required for substrate fermentation (25.0-35.0) , if no exogenous nitrogen is added for adjustment, it is easy to cause a relative lack of nitrogen in the fermented material, thereby reducing the decomposition rate of organic matter, prolonging the fermentation process, and problems such as incomplete nutrient decomposition and incomplete sterilization.
In the prior art, there is no relevant report on the production of organic cultivation substrates by fermenting broad bean stalks as the main raw material

Embodiment 1

[0036] A broad bean stalk organic cultivation substrate, the raw material volume ratio is as follows:

[0037] Broad bean straw fermented product: mushroom dregs fermented product: decomposed cow dung: river sand=2.5:2:2.5:3.

[0038] The preparation method of this substrate comprises:

[0039] 1. Preparation of broad bean straw fermented product and mushroom dregs fermented product

[0040] (1) After broad beans are harvested, the stalks are naturally air-dried to semi-dry (moisture content 30%-40%), and crushed to 2.0-5.0cm with a kneading shredder. Pleurotus ostreatus bags are removed from the bag and crushed to a particle size of ≤0.5cm.

[0041] (2) Broad bean stalks and mushroom dregs are piled and fermented according to the standards of bottom width 4.0-5.0m, top width 1.0-2.0m, and height 1.0-1.5m. Add water every 20-25cm thickness, and repeat this 4-5 times, the stacking is successful.

[0042] Among them, broad bean straw is added at 1.8-2.5‰ (mass ratio), mushroo...

Embodiment 2

[0052] A broad bean stalk organic cultivation substrate, the raw material volume ratio is as follows:

[0053] Broad bean straw fermented product: mushroom dregs fermented product: decomposed chicken manure: river sand =3:2:2:3

[0054] For the preparation method of the substrate, compared with Example 1, the difference is that the decomposed cow dung in step 3 is replaced with decomposed chicken manure, and the broad bean straw fermented product, mushroom dregs fermented product, decomposed chicken manure, and river sand are prepared according to 3 : The volume ratio of 2:2:3 is compounded, and the rest of the steps are the same.

Embodiment 3

[0056] A broad bean stalk organic cultivation substrate, the raw material volume ratio is as follows:

[0057] Broad bean straw fermented product: mushroom dregs fermented product: decomposed chicken manure: field soil = 6:2:1:3

[0058] For the preparation method of the matrix, compared with Example 1, the difference is that the sand river in step 2 is replaced by field soil, the decomposed cow dung in the soil in step 3 is replaced by decomposed chicken manure, and the broad bean straw fermented product, mushroom dregs The fermented product, decomposed chicken manure, and river sand are compounded according to the volume ratio of 6:2:1:3, and the rest of the steps are the same.

[0059] Comparative test data

[0060] For the broad bean straw organic cultivation substrates obtained in the above-mentioned Examples 1, 2, and 3, the main physical properties were measured respectively and compared with the commercially available straw peat organic cultivation substrates (Ruiyang...

Abstract

The invention relates to an organic cultivation medium made of broad bean straw and a preparing method thereof. The organic cultivation medium is prepared from, by volume, 25%-50% of fermented broad bean straw, 0%-20% of fermented mushroom residues, 8%-25% of an organic fertilizer and the balance base material, wherein the organic fertilizer is one or two of decomposed chicken manure and decomposed cow manure, and the base material is one of river sand and field soil. According to the organic cultivation medium made of broad bean straw and the preparing method thereof, the organic cultivationmedium with the excellent physical and chemical properties is obtained through broad bean straw fermentation production, external source nitrogen does not need to be added for adjustment, the production cost is reduced, the decomposing speed of organic matter is increased, the fermentation process is shortened, and nutrients of fermentation products are more complete and are more sufficient. The preparing method is simple and easy to implement, the preparing efficiency is high, and the organic cultivation medium is easy to industrially popularize.

Description

technical field [0001] The invention relates to the field of organic cultivation substrates, in particular to an organic cultivation substrate made from broad bean stalks and a preparation method thereof. Background technique [0002] Organic cultivation substrate refers to the use of crop straw, mushroom residue, peat, sawdust, livestock and poultry manure, etc., after fermentation or high temperature treatment, mixed with river sand, cinder, vermiculite, perlite and other inorganic substances in a certain proportion to form a Relatively stable and buffering full-nutrient cultivation substrate raw material. Organic cultivation substrate is a new high-efficiency soilless cultivation method. Compared with traditional soil cultivation, it has the advantages of avoiding continuous cropping obstacles, improving crop yield and quality, not limited by geographical conditions, and saving water, fertilizer and labor. [0003] The earlier organic substrates mainly used peat, a non-r...
