Problems solved by technology

However, peat is produced in the Northeast, resources are scarce, and it cannot be regenerated. Enterprises in Jiangsu use peat at high cost; reed powder, traditional Chinese medicine residue, mushroom residue, etc. are large in size and need to be crushed; Difficulties and other deficiencies, it is difficult to meet the needs of industrial seedlings
Although there are reports of using vinegar residues to produce substrates, the substrates are prepared according to the requirements of transplanted green seedlings, and are mainly suitable for the survival and growth of transplanted seedlings. The particles are relatively thick and the nutritional requirements are not high, so they are not suitable for seedling raising substrates; while Jiangsu Li Pingping of the University used vinegar grains to produce plant seedlings and cultivation substrates. Because it was put forward earlier, some production processes are not too mature, and it is mainly used for cultivation, not a strict special seedling substrate.

Abstract

The invention discloses a seedling substrate for vegetables, belonging to the technical field of soilless culture. The substrate formula comprises the following components based on volume ratios: 10-40% of fermented vinegar dreg, 5-30% of fermented cassava dreg, 5-30% of plant ash, 5-30% of perlite, 5-30% of vermiculite and 10-25% of turf. The water content of the substrate is not bigger than 50%, and the total porosity of the substrate is 65-95%, and the total nutrient content of the substrate (N+P2O5+K2O) is 3-5%, and the grain diameter of the substrate is 0.1-4.9 mm, and the volume weight of the substrate is 0.2-0.8 g / cm3, and the gas-water ratio of the substrate is 1: 2-4, and the EC (elastic coefficient) value of the substrate is 1-3 and the pH value of the substrate is 5.8-7.5. The seedling substrate for soilless culture for vegetables mainly uses organic wastes as raw materials, and produces seedling substrate by high temperature fermentation treatment, and changes wastes into wealth, and turns harm into good. The invention has a low production cost, a light weight and complete nutrients such that it is suitable for growth and development for vegetable seedlings, and is a good substrate for soilless culture industrialized tray seedling for vegetables.

Description

technical field [0001] The invention relates to a nutrient substrate for soilless cultivation of vegetables, in particular to a seedling substrate for soilless cultivation of vegetables, and belongs to the technical field of soilless cultivation of vegetables. Background technique [0002] Soilless cultivation refers to a cultivation method that uses substrate or nutrient solution to irrigate without using natural soil. It is mainly used on vegetables or flowers. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. This technology originated from In the middle of the 19th century, it began to be applied to agricultural production in the 1930s. It was widely used in the Netherlands, Japan, New Zealand, Italy and other countries. At present, soilless cultivation technology has been applied and developed in more than 100 countries around the world. [0003] my country's soilless cultivation technology research and application started r...
