Vegetable-fruit cultivation matrix

Abstract

The invention discloses a vegetable-fruit cultivation matrix which is composed of, by weight, 20-30 parts of modified bamboo charcoal, 14-15 parts of fermented bran, 3-5 parts of calcium carbonate, 20-25 parts of fermented bean meal, 10-12 parts of pleurotus eryngii residue, 3-4 parts of traditional Chinese medicine residue, 5-6 parts of vinegar residue, 20-25 parts of peat, 10-12 parts of perliteand 5-8 parts of coco coir. The preparation method includes: phosphoric acid activation, carbonization, bean meal fermentation, bran fermentation and compounding. The vegetable-fruit cultivation matrix has the advantages that the cultivation matrix contains rich nutritional elements, has high water retention ability and porosity is free of caking and salination, conducive to improving disease-resistant antibacterial ability to plants and high in efficiency and quality.

Description

technical field [0001] The invention relates to the field of vegetable and fruit cultivation, in particular to a vegetable and fruit cultivation substrate. technical background [0002] In recent years, my country's protected horticulture has developed rapidly, but in many areas, the types of fruits and vegetables cultivated in protected areas are single, and the problems of secondary salinization and continuous cropping obstacles are common and prominent, which have become unfavorable factors that limit the development of the protected fruit and vegetable industry. At the same time, with the rapid development of the chemical industry, the problems of excessive nitrate and pesticides in the production of fruits and vegetables have become more and more serious. Fruits and vegetables have lost their original natural taste, and food safety issues have attracted social attention. The existing fruit and vegetable production bases above designated size are difficult to develop and...

[0003] The prior art, such as the Chinese invention patent whose authorized public number is CN 103253992 B, discloses an organic cultivation substrate produced by composting pig manure and sludge and a production method thereof. The inventive method first decomposes and ferments pig manure, and then The urban domestic sludge and bacterial residue are decomposed, fermented and composted, and then the decomposed pig manure and sludge are composted and fermented to form an organic cultivation substrate. The cultivation substrate in the inventive method has low salt content, moderate nutrients, and does not damage the environment. It can meet the requirements of organic cultivation, but the method of the invention does not process the heavy metal ions in the substrate, which will cause a high content of heavy metal ions in the substrate and affect the growth of crops. The content of organic matter and nutrients, resulting in the waste of nutrients
