Water and fertilizer conservation attapulgite clay vegetable cultivation matrix

Abstract

The invention discloses a water and fertilizer conservation attapulgite vegetable cultivation matrix. The raw material of the matrix comprises, by weight, 60-80 parts of attapulgite clay, 10-20 partsof zeolite powder, 6-14 parts of diatomite, 15-25 parts of sepiolite powder, 4-6 parts of calcined kaolin, 3-5 parts of gangue, 2-5 parts of phosphate rock powder, 3-6 parts of quartz sand, 4-10 partsof waterproof binder, 95-105 parts of organic fertilizer, 15-25 parts of coconut shell charcoal powder and 4-8 parts of corn straw. The waterproof binder is prepared by the following processes: bovine collagen, polysorbate, and water are stirred and freeze-dried, sodium carboxymethyl cellulose and acetic acid aqueous solution are added, heated, stirred and freeze-dried to obtain the waterproof binder. The matrix is comprehensive in nutrients, the matrix is loose, the specific surface area is extremely large, the adsorption strength is high, the nutrients are not easy to lose, the shape structure can be effectively maintained, the phenomenon of collapse does not easily occur, the structure characteristic of water and fertilizer conservation is effectively maintained, meanwhile, environmental pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation substrates, in particular to a water- and fertilizer-retaining attapulgite vegetable cultivation substrate. Background technique [0002] Soilless cultivation refers to the method of cultivating with substrate instead of natural soil. It is mainly used in vegetables or flowers. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. [0003] Substrate cultivation is a method with the largest promotion area in soilless cultivation. At present, most countries in the world use gravel, sand, peat, sepiolite powder, diatomaceous earth, rock wool, sawdust, etc. as fixed substrates. With the promotion and application of soilless cultivation technology, the demand for substrates is increasing, and the types of substrates are becoming more and more abundant. Attapulgite is used as a cultivation substrate, and it is more and more widely used. Attapulgite...

Problems solved by technology

With the promotion and application of soilless cultivation technology, the demand for substrates is increasing, and the types of substrates are becoming more and more abundant. Attapulgite is used as a cultivation substrate, and it is more and more widely used. Attapulgite is also called palygorskite or Palygorskite is a kind of hydrous magnesium-aluminosilicate clay mineral with a chain layer structure. However, the attapulgite cultivation substrate currently has technical problems such as poor adsorption effect and easy loss of nutrients, which is difficult to meet the needs of vegetable substrate cultivation. need
