Problems solved by technology

In addition, as a kind of agricultural waste, mushroom residues are produced in huge quantities every year along with the development of the edible fungus industry. However, how to deal with environmental protection and effective mushroom residues has not been well resolved.
A large number of fungal residues are piled up on the spot, which on the one hand causes a huge waste of agricultural organic resources and on the other hand causes environmental pollution

Embodiment 1

[0029] The invention discloses a water- and fertilizer-retaining cultivation substrate compounded with bentonite and fungus residue. The substrate comprises the following components in parts by weight: 35 parts of bentonite, 65 parts of fungus residue and 0.3 part of compound fertilizer.

[0030] The preparation method of the water-retaining and fertilizer-retaining cultivation substrate compounded with bentonite and fungus residue is prepared by mixing the discarded fungus residue with bentonite evenly after being fermented and decomposed. The specific steps include:

[0031] (1) Pre-treatment of the bacteria residue:

[0032] Select the waste fungus bag freshly removed from the shelf after the edible fungus is planted. The waste fungus material is processed by removing the bag and crushed to 1-3cm particles. Add 0.2kg of compound microbial agent and 0.5kg of urea to each cubic meter of granules to ensure composting and fermentation. The medium carbon-nitrogen ratio is 20; af...

Embodiment 2

[0051] In May 2012, the inventor conducted a potted test of cabbage with bentonite and fungal residue as a composite cultivation substrate at the Wenjiang Campus Test Site of Sichuan Agricultural University. Apply comparison.

[0052] There are six treatments in the test: control sandy soil CK1, loam soil CK2, composite cultivation substrates T1, T2, T3, and T4 with different proportions of bentonite and fungal residue, and the weight ratios of bentonite and fungal residue are 1:1, 1:1.5, and 1 :2, 1:2.5. The composition of each treatment (according to the amount per pot) is shown in Table 4 below, and each treatment has 4 replicates.

[0053] The compound fertilizer used in this example is 25% compound fertilizer produced by Sinochem Shandong Fertilizer Co., Ltd., which contains N (15%), P (5%), and K (5%). The variety of cabbage used is Tourmaline Phoenix.

Embodiment 3

[0061] In April 2012, the inventor conducted a potted test of pepper with bentonite and fungus residue composite cultivation substrate in Wenjiang Campus of Sichuan Agricultural University. According to the preparation method described in the present invention, the substrates prepared with different ratios of bentonite and fungus residue were used for comparison. .

[0062] There are six treatments in the test: control sandy soil CK1, loam soil CK2, composite cultivation substrates T1, T2, T3, and T4 with different proportions of bentonite and fungal residue, and the weight ratios of bentonite and fungal residue are 1:1, 1:1.5, and 1 :2, 1:2.5. The composition of each treatment (according to the amount per pot) is shown in Table 1 below, and each treatment has 4 replicates.

[0063] The compound fertilizer used in this example is 25% compound fertilizer produced by Sinochem Shandong Fertilizer Co., Ltd., which contains N (15%), P (5%), and K (5%). The pepper variety used is ...

Abstract

The invention relates to the technical field of the water-retention fertilizer-conservation cultivation for the drought-resistant forestation of the agriculture and forestry, and concretely relates to a bentonite and fungal dreg compounded water-retention fertilizer-conservation cultivation matrix and its preparation method. The matrix comprises 30-40 parts of bentonite, 60-70 parts of fungal dreg and 0.1-0.5 parts of a composite fertilizer. The preparation method of the matrix comprises the following steps: selecting new waste fungal bags after the edible fungus plantation, carrying out bag removal treatment, crushing, and adding a composite microbial agent and urea to guarantee the C:N ratio of 20; fully and uniformly mixing the above raw materials, adjusting the water content to 60%, composting the fungal dreg, and storing the obtained compost in a ventilation and rain exposing prevention device for the decrease of the water content to 20%; and uniformly mixing the fungal dreg with bentonite and the composite fertilizer, and crushing to prepare the water-retention fertilizer-conservation cultivation matrix. The matrix has the advantages of abundant sources and low costs of raw materials, wide distribution and low cost of a bentonite mineral resource, large output and easy obtaining of the waste fungal dreg, simple making method, and no pollution to the environment.

Description

technical field [0001] The invention relates to a water-saving and fertilizer-conserving cultivation substrate for drought-resistant afforestation in agriculture and forestry and a preparation method thereof, in particular to a water-saving and fertilizer-conserving cultivation substrate suitable for arid and sandy afforestation, specifically bentonite and fungus slag A composite water- and fertilizer-retaining cultivation substrate and a preparation method thereof. Background technique [0002] In arid and semi-arid areas, on the one hand, water resources are scarce, and natural precipitation cannot meet the water requirements of plants, and plants often face water shortages; waste. Afforestation in arid and semi-arid areas usually adopts the method of raising seedlings and transplanting, but the root system of plant seedlings is shallow and the number is small, which cannot absorb sufficient water and nutrients, and the survival rate is low. Therefore, afforestation in t...
