Embodiment 1

[0028] Chicken manure fermentation biogas residue, its composition: organic matter content 50%, humus content 20%, total nitrogen content 1.4%, total potassium content 0.7%, total phosphorus content 1.6%, moisture content 25%. Take 400g of biogas residue and 600g of straw residue, stir and mix the straw residue with 12g / L sodium alginate 1000mL to form mixture A, dry it to a moisture content of 25%, take 400g of mixture A, 0.4g of nutrition regulator, and 1.24g of acidity regulator , mix evenly and press it into straw bowl 1, then take 200g of mixture A and mix it with biogas residue, fill it into straw bowl 1, replace the mold, pressurize at 1.6-2.0 MPa, keep the pressure for 5 seconds, and drop to normal pressure , to obtain the inner core 2, and punch the seeding hole 1 on it to obtain the sandwich nutritional block product.

Embodiment 2

[0030] Cow dung fermented biogas residue, its composition: organic matter content 41%, humus content 22%, total nitrogen content 0.9%, total potassium content 0.8%, total phosphorus content 0.4%, moisture content 25%. Take 400g of biogas residue and 600g of straw residue, stir and mix the straw residue with 12g / L sodium alginate 1000mL to form mixture A, dry it to a moisture content of 25%, take 400g of mixture A, 0.4g of nutrition regulator, and 1.24g of acidity regulator , mix evenly and press it into straw bowl 1, then take 200g of mixture A and mix it with biogas residue, fill it into straw bowl 1, replace the mold, pressurize at 1.6-2.0 MPa, keep the pressure for 5 seconds, and drop to normal pressure , to obtain the inner core 2, and punch the seeding hole 1 on it to obtain the sandwich nutritional block product.

Embodiment 3

[0032] Human feces and straw mixture fermented biogas residue, its composition: organic matter content 30%, humus content 17%, total nitrogen content 0.8%, total potassium content 0.6%, total phosphorus 1.6%, moisture content 25%. Take 400g of biogas residue and 600g of straw residue, stir and mix the straw residue with 12g / L sodium alginate 1000mL to form mixture A, dry it to a moisture content of 25%, take 400g of mixture A, 0.4g of nutrition regulator, and 1.24g of acidity regulator , mix evenly and press into straw bowl 1, then take 200g of mixture A and mix it with biogas residue, fill it into straw bowl 1, replace the mold, pressurize 1.6-2.0 MPa, keep the pressure for 5 seconds, and drop to normal pressure , to obtain the inner core 2, and punch the seeding hole 1 on it to obtain the sandwich nutritional block product.

Abstract

The invention related to a composite biogas residue sandwiched nutrient medium block which is obtained by taking fermentation products of planting and breeding wastes (poultry feces and straw) as main raw materials and processing the main raw materials. The invention has the advantages of wide raw material source, reasonable nutrient component and capability of promoting the seed germination and the seedling growth, and can solve the problems of low seed germination rate and damage to seedlings in the process of carrying out rapid breeding by utilizing the existing seedling culture medium.

Description

technical field [0001] The invention relates to a compound biogas residue sandwich nutrient matrix block, and also provides a processing method thereof, belonging to the technical field of crop seedling raising. Background technique [0002] In recent years, peat (peat) is mostly used as raw material for seedling-raising substrate blocks. On the one hand, the reserves of high-quality peat are low, and on the other hand, the mining of peat destroys vegetation, which is not suitable for large-scale processing and application. At present, the formula of the seedling-raising matrix block is single and the processing method is rough, because the specificity of the nutrient components required for seed germination and seedling growth, and the characteristics of multi-level utilization of available N, P, and K in different growth stages are not fully considered. Therefore, the existing seedling-raising matrix block seeds have a low germination rate, damage the seedling line, and e...
