Problems solved by technology

[0003] However, continuous cropping, soil compaction, chemical fertilization and pesticide poisoning all year round lead to a decrease in the reproductive rate of field earthworms and a loss of biomass, which in turn produces a cyclical effect of soil deterioration
Earthworms are extremely sensitive to nutrient ions. Food wastes with high calcium content and agricultural and industrial wastes rich in nitrogen and potassium are beneficial to improve the survival rate of worm eggs, but these nutrients cannot be directly utilized by earthworms.

Embodiment 1

[0051] The present embodiment provides a kind of preparation method of earthworm breeding companion soil restoration agent, comprising:

[0052] (1) Preparation of thermogenic ion-enriching bacterial agent: compound the mass ratio of composting Nocardia sp., Saccharomyces cerevisiae, Trichoderma reesei and Aspergillus oryzae to prepare thermoionic ion-enriching bacterial agent;

[0053] (2) Preparation of paragonadal ion stress matrix: mix soybean meal, plant ash, and bone meal to obtain material, add 1 kg of thermogenic ion-enriching bacterial agent for every 10 tons of material, mix well, and pile up the material into a cone shape. The natural fermentation keeps the water content at 50%, and when the fermentation temperature reaches 40°C, it is turned over once a day, and fermented for 15 days to obtain the paragonad ion stress matrix, wherein, in parts by weight, the soybean meal is 3 part, the plant ash is 3 parts, and the bone meal is 1 part;

[0054] (3) Preparation of ...

Embodiment 2

[0063] Embodiment 2 (do not have warming starter)

[0064] In this example, compared with Example 1, the decomposing fermentation of the paragonad ion-stressed substrate is natural fermentation—no thermogenic ion-enriching bacterial agent is added, and other preparation process conditions are the same as in Example 1.

[0065] The end point of decomposing fermentation was judged by the bio-organic fertilizer standard NY 884-2004, and the temperature and time of fermentation were recorded.

[0066] Table 1 Comparison of decomposing and fermentation time under different temperatures

[0067]

[0068] As can be seen from Table 1, due to the low-temperature fermentation activity of the temperature-starting fermentation agent, the temperature-starting agent can rapidly heat up and start the fermentation of the substrate under low temperature conditions (5-15° C.). Compared with natural fermentation, the fermentation period is shortened. About two months; even under normal tempe...

Embodiment 3

[0069] Embodiment 3 (traditional earthworm propagation substrate)

[0070] Compared with Example 1 in this example, the paragonad ion stress substrate is animal manure and silt soil, and other preparation process conditions are the same as in Example 1.

[0071] According to the national standard GB / T 21633-2008 and GB / T 19203-2003, the content of total nitrogen, phosphorus, potassium and calcium elements in the decomposed substrate was determined.

[0072] Table 2 Comparison of element content in different substrates

[0073]

[0074] Nitrogen, phosphorus, potassium and calcium are essential nutrients for crops, and they are also stress elements that increase the reproductive rate of earthworms. As shown in Table 2, compared with the traditional feces + silt soil matrix, the concentration of various elements in the ion stress matrix has been significantly increased, and the nitrogen, phosphorus, potassium and calcium elements have increased by 2.74, 2.59, 2.67 and 1.92 ti...

Abstract

The invention provides a preparation method and a product of an earthworm breeding companion soil remediation agent. The soil remediation agent is used for soil remediation by taking earthworm biomass improvement as a target, a rotten earthworm glandula accessoria ion stress matrix is used as a substrate, an antibacterial earthworm fiber skeleton is filled, an annulata earthworm cocoon synthesis promoting agent benefiting earthworm cocoon, an earthworm symbiotic bacterium agent and an artificial earthworm cocoon barrier are matched, so that the remediation agent is formed. The biomass of the soil earthworm cocoons and earthworms can be increased by 4.40 and 2.9.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a preparation method and product of an earthworm breeding companion soil restoration agent. Background technique [0002] Earthworms are natural biological aids for soil improvement. Earthworms are predators of disease-causing fungi, bacteria, and microscopic soil animals. The peristalsis of earthworms can promote the optimization of soil particle size and pores; earthworm mucus is rich in probiotic polysaccharides, antibacterial mucins and soil nutrients; cellulose and humic organic matter that are difficult to degrade in soil can be eaten by earthworms, and then transformed into Crops can use decomposed high-quality organic fertilizer nutrients. [0003] However, continuous cropping, soil compaction, chemical fertilization and pesticide poisoning all year round lead to a decrease in the reproductive rate of field earthworms and a loss of biomass, which in ...
