Cultivation and seedling growing matrix for melons and vegetables

Abstract

The invention relates to a cultivation and seedling growing matrix for melons and vegetables. The matrix is formed by uniform mixing of the following raw materials by weight: 10-25% of urea formaldehyde resin foam particles, 15-35% of fermented two-mushroom residue, and 30-55% of peat. The preparation method of the fermented two-mushroom residue includes: mixing agaricus bisporus residue with flammulina velutiper residue according to 1:(0.7-1.2), conducting windrow fermentation, when the temperature reaches above 65DEG C, conducting pile-turning once every day, and when water decreases to less than 40%, conducting sieving by a 5mm sieve, thus obtaining fluffy fermented two-mushroom residue. The urea formaldehyde resin foam involved in the invention is granular and has small particle size, is convenient for water retention and air permeability, is beneficial to rooting and fast sprouting, and also puts an end to the use of perlite and vermiculite, reduces the dust harmful to the human body in production, and has pH of 5.5, and after uniform mixing with the fully fermented two-mushroom residue, the pH is about 6.5. By using the above three raw materials, discharge of solid waste is reduced. As the urea formaldehyde resin foam particle production involves certain formaldehyde, various pathogens in the seedling growing and cultivation matrix can be effectively killed, thus avoiding the investment of bactericide before use by a user.

Description

Technical field: [0001] The invention relates to the technical field of cultivation and seedling-raising substrates, in particular to a melon and vegetable cultivation and seedling-raising substrate. Background technique: [0002] Soilless culture (soilless culture) refers to the cultivation method that does not use natural soil but uses substrate or only substrate when raising seedlings, and irrigates with nutrient solution after planting, which can increase the stubble and shorten the planting cycle, thus saving land. Artificially create a good rhizosphere environment, effectively prevent soil continuous planting diseases and physiological obstacles caused by soil salt accumulation, fully meet the needs of crops for mineral nutrition, water, gas and other environmental conditions, and the basic materials for cultivation can be recycled, so It has the characteristics of water saving, fertilizer saving, labor saving, high yield and high quality, and environmental friendlines...

Problems solved by technology

This kind of matrix is ​​not ideal because the lower layer is plate-shaped, which consumes a lot of urea-formaldehyde resin foam. In addition, the nutrients are located on the upper layer, and the seedlings are rooted on the urea-formaldehyde resin foam board. The nutrients are not easy to reach the roots, and the effect is not ideal; Moreover, the urea-formaldehyde resin foam board is not easy to dispose of after use, and the decomposition speed is still not ideal after being buried in the soil, and it becomes a relatively difficult to dispose of garbage

[0005] Agaricus bisporus slag is fine and sticky and will not ferment again. The nutrient content of nitrogen, phosphorus and potassium is low, only about 3%. It is not easy to dehydrate, and it is not easy to dry in the sun after long-term storage. It is still sticky and not dry after three years of storage in large piles, resulting in cross flow of sewage, which is difficult. Radical environmental protection sequelae, and its specific gravity is more than 800kg per cubic meter, so it is difficult to utilize. Flammulina velutipes fluffy particles are large, and the content of nitrogen, phosphorus and potassium is 5-7%, and it is easy to dry. The specific gravity is below 500kg per cubic meter, but because it contains Miscellaneous bacteria, directly used in the production of seedling substrate and organic fertilizer, easy to grow Flammulina velutipes, often affect the growth of seedlings, resulting in product quality accidents
