Embodiment 1
[0021] First, the fresh seaweed residue with a water content of about 85% is dried in the sun or other methods to reduce the water content to between 50% and 55%. Secondly, press the seaweed residue by about 1.5m 3 The length, width and height are 1.5m, 1.0m, and 1.0m respectively, and then covered with plastic film for heat preservation, and the pile is turned once every 3 days on average. During the fermentation process, the water content in the heap should be controlled between 45% and 50%, until the temperature of the fermentation heap decreases and reaches a stable state in the later stage, the color of the seaweed residue is dark brown, the pH value is stable at 7.5 to 8.5, and the EC value reaches a stable state , which means that the composting fermentation of seaweed residue is basically completed.
Embodiment 2
[0023] First, adjust the water content of fresh cassava residues to about 60% by drying or other means. Secondly, add urea (N%=46.3%) to adjust C / N to 30:1 in cassava residue raw material as the case may be, and mix it by about 5.4m 3 The length, width and height of the stacks are 3.0m, 1.5m and 1.2m respectively, and then covered with plastic film for heat preservation, and the piles are turned over once every 5 days on average. During the fermentation process, the water content in the heap should be controlled at about 60% until the temperature of the fermentation heap decreases and reaches a stable state in the later stage, and the physical and chemical indicators such as the EC value reach stability, which means that the composting of cassava dregs is basically completed.
Embodiment 3
[0025] First, adjust the water content of fresh mushroom dregs (waste compost produced by industrialized Flammulina velutipes) to about 60% by drying or other methods. Second, every 1m 3 Add 0.7Kg of urea (N%=46.3%) and 3Kg of chicken manure in the fresh mushroom dregs, mix it and press it into about 3.75m 3 The length, width and height are 2.5m, 1.5m, and 1.0m respectively, and then covered with plastic film for heat preservation, and the pile is turned once every 7 days on average. During the fermentation process, the water content in the heap should be controlled between 55% and 60%, until the temperature of the fermentation heap decreases in the later stage and reaches a stable state, the fermented material turns from light yellow to dark brown, and the physical and chemical indicators such as EC value reach stability, which means that the mushroom The slag composting fermentation is basically completed.

Abstract
The invention discloses a functional nursery matrix and application of the functional nursery matrix. The nursery matrix comprises basic mixed material with thoroughly decomposed seaweed residue, thoroughly decomposed cassava residue and thoroughly decomposed mushroom residue being raw material, wherein the volume ratio of the thoroughly decomposed seaweed residue to the thoroughly decomposed cassava residue to the thoroughly decomposed mushroom residue is 30-50:18-42:18-42. The nursery matrix further contains a water-retaining agent of 0.5-8g / L and bio-organic fertilizer of 3-36g / L. The seaweed residue, the cassava residue and the mushroom residue with a specific ratio are screened out of commonly used biological matrixes and mixed and prepared to serve as the basic mixed material, and the functional nursery matrix can effectively promote the growth of tomatoes. On this basis, the specific amount of bio-organic fertilizer and water-retaining agent are added, and the bio-organic fertilizer and water-retaining agent can have a collaborative effect; compared with separate addition of the bio-organic fertilizer and water-retaining agent, the chlorophyll content in leaves can be remarkably increased, the photosynthesis of various vegetable crops is promoted, and the stress resistance of the crops is enhanced. Accordingly, robust growth of the plants is substantially promoted, the output of the crops is increased, and the quality of the crops is improved.
Description
technical field [0001] The invention belongs to the field of fertilizers, and relates to a functional seedling-raising substrate and its application, in particular to a functional seedling-raising substrate for tomato and its application. Background technique [0002] In recent years, with the rapid development of facility agriculture at home and abroad and consumers' preference for green and organic agricultural products, more and more attention has been paid to industrial seedling raising and organic substrate cultivation. Therefore, choosing a seedling substrate suitable for seedling growth has become the key. In addition, the rapid development of modern agriculture and industry has produced a large amount of industrial and agricultural waste, which has polluted the environment. Therefore, using various industrial and agricultural wastes, such as animal manure, crop stalks, seaweed residues, cassava residues, mushroom residues and other raw materials for composting and fe...
