Vegetable seedling raising matrix

Abstract

The invention discloses a vegetable seedling raising matrix, which belongs to the technical field of soilless cultivation. The vegetable seedling raising matrix is mainly prepared from the following raw materials in parts by weight: 60 to 70 parts of decomposed pine needles, 29 to 39 parts of coco coir, 0.3 to 0.35 part of calcium magnesium phosphate fertilizer, 0.3 to 0.35 part of potassium sulfate, and 0.3 to 0.35 part of ammonium sulfate; the water content of the matrix is 28 to 34 percent, the total porosity is 75 to 80 percent, the particle size is 0.3 to 0.5 mm, an air-water ratio is 1:(3.5 to 4), and a pH value is 6.5 to 7.3. The vegetable seedling raising matrix of the invention is scientific and reasonable in raw material proportioning; by adopting the decomposed pine needles andcoco coir as main raw materials, the vegetable seedling raising matrix is long in fertilizer effective time, balanced in nutrition, good in matrix permeability, high in water absorption, resistant tobacteria, pollution-free, capable of promoting the growth of vegetable seedlings with good growth, and capable of increasing the seed sprouting rate, and the cultivated vegetable seedlings are high in yield, good in quality and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation of vegetables, in particular to a substrate for raising vegetable seedlings. Background technique [0002] The traditional cultivation of vegetables is mainly based on open-field soil cultivation. With the advancement of science and technology, soilless cultivation techniques in facilities are gradually developed and applied, such as hydroponics, aeroponics, and substrate cultivation. Because soil cultivation is prone to continuous cropping obstacle diseases, soil cultivation has certain limitations. Now soilless cultivation technology has become an important part of the field of fruit and vegetable planting, and there are many types of seedling culture substrates on the market. However, most seedling culture substrates still have the shortcomings of short fertilizer effect time, unbalanced nutrition, poor air permeability of the substrate, and weak water absorption, which lead to po...
