Problems solved by technology
Due to the limited and uneven distribution of peat resources in my country, the cost of long-distance transportation is high, and peat is a non-renewable resource in the short term, excessive exploitation will lead to resource depletion and environmental damage, so seeking peat substitutes is one of the hot spots in matrix research.
On the other hand, the current intensive seedling cultivation mainly adopts the method of sprinkling nutrient solution on the seedlings, which has high technical requirements and cumbersome operation and management. Poor management may easily cause uneven water and nutrient supply among seedlings, and large-scale irrigation will cause fertilizer and water loss and environmental pollution. series of questions

Embodiment 1
[0016] A nutritional and water-saving soilless seedling cultivation substrate for tomatoes, which is made of fermented cottonseed shell mushroom residue, peat, and vermiculite in a ratio of 1:1:1 (v:v:v); fermented cottonseed shell mushroom residue Cottonseed shell mushroom residue with a water content of 60-70% (mass percentage) is used for high-temperature static stacking and retting fermentation for more than 60 days, fully decomposed, air-dried, crushed, and passed through a 5mm sieve to remove coarse residues or impurities. The particle size of vermiculite is about 1mm. Add 4kg of water-retaining agent and 4kg of controlled-release compound fertilizer to each cubic meter of substrate and mix well. Controlled Release Compound Fertilizer N, P 2 o 5 、K 2 The O content is 14%, 14%, 14% (mass percentage), the film content is 5% (mass percentage), the control application period is 3 months, and the particle size is 3.0-3.5mm. The water retaining agent is a cross-linked poly...

Abstract
Nutrient water-saving substrate special for soilless raising of tomato seedlings is formed by mixing fermented cottonseed hull mushroom residue, peat and vermiculite according to a proportion 1:1:1 (v:v:v). The vermiculite is about 1mm in particle size, and 4kg of water-retaining agent and 4kg of controlled-release compound fertilizer are added per square meter of the substrate and fully mixed well. The nutrient water-saving substrate compared with conventional seedling raising substrate has the advantages that firstly, resources are saved, labor is economized, consumption of the peat is reduced by 50%, the nutrient water-saving substrate has the functions of nutrition and water retaining, operational management can be simplified, fertilizer, water and labor are economized; secondly, the nutrient water-saving substrate is safe, environment-friendly and pollution-free; and thirdly, seedling raising quality and efficiency are improved.
Description
technical field [0001] The invention relates to a special functional substrate which integrates peat replacement, nutrition and water retention and is suitable for intensive soilless seedling cultivation of tomatoes, and belongs to the field of agricultural high-tech. Background technique [0002] Seedling raising is an important technical link in vegetable production. The quality of seedlings directly affects the growth, yield and quality of vegetables. With the standardization, scale and specialization of vegetable production in my country, vegetable seedling cultivation has gradually changed from traditional exclusive single-family soil seedling cultivation to intensive soilless seedling cultivation, thereby greatly improving the efficiency of seedling cultivation. At present, the soilless seedling substrate is mainly composed of peat, vermiculite or perlite. [0003] "Peat", also known as "peat", is composed of swamp plant residues that cannot be completely decomposed a...
