Vinegar residue composite matrix for cultivating green-leaf vegetables

Abstract

The invention belongs to the technical field of plant cultivation, and discloses a vinegar residue composite matrix for cultivating green-leaf vegetables. The vinegar residue composite matrix comprises the following components in parts by weight: 30 to 70 parts of vinegar residue, 1 to 20 parts of coco coir, 1 to 10 parts of perlite, 5 to 30 parts of plant ash and 1 to 40 parts of vermiculite. Each physicochemical property of the vinegar residue composite matrix conforms to the growth requirement of the green-leaf vegetable, the matrix is used for cultivating pakchoi, three-colored amaranth, watercress, Chinese chives or lettuce, the requirements of the green-leaf vegetable on the nutrition, oxygen and water can be met, the cultivation effect is obviously influenced, and the plant is strong. In addition, the vinegar residue composite matrix is simple in formula, the raw material is domain on the organic waste fermented product, the waste is recycled, the raw materials are conventional nutritional substrate on the market, compounding is easy, and the vinegar residue composite matrix is suitable for the large-scale cultivation and production of green-leaf vegetables on the research production.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a vinegar grain composite substrate for green leafy vegetable cultivation. Background technique [0002] Vinegar grains matrix has the characteristics of coarse particles, large ventilation porosity, high acidity, high EC value, and not easy to decompose, so it is not suitable for use as a cultivation substrate alone. However, it can be adjusted by adding common substrates such as vermiculite, perlite and peat, or by adding other organic waste substrates to suit the needs of crop growth. The compound matrix is ​​a mixture of different substrates in nature, structure and performance, and the coordination effect of moisture and fertilizer is better than that of a single matrix. However, with different matrices and proportions, the performance of the compound matrices is also different, so that the effect of different compound matrices on crop seedlings will a...

Problems solved by technology

At present, the ratio of substrates for green leafy vegetable plug cultivation in the market is very chaotic, resulting in poor physical and chemical properties of substrates, poor permeability, poor water and fertilizer retention capacity, etc., resulting in poor root development of seedlings, thin plants, and poor resistance, which seriously affects the cultivation of green leafy vegetables. plant quality
