Soilless culture substrate for wheat

Abstract

The invention discloses a soilless culture substrate for wheat. The soilless culture substrate is characterized by being prepared from the following raw materials and components in parts by weight: 50 to 60 parts of fermentation residue, 25 to 35 parts of bentonite, 15 to 20 parts of plant ash, 8 to 12 parts of perlite, 6 to 8 parts of turf, 4 to 6 parts of lignite powder, 6 to 8 parts of cow chip, and 2 to 3 parts of medical fertilizer; vinegar residue and furfural are inorganic wastes and can be used for producing soilless culture substrate of vegetable, so that the environmental pollution can be reduced, and the wastes can be turned into property; the plant ash contains relatively high potassium content, so that the pH of the fermenting vinegar residue substrate is reduced, and therefore, the soilless culture substrate has the characteristics of being nutritional, resistant to diseases, and improving seedlings; the substrate is high in water-retaining property and suitable for growth and development of seedlings.

Description

Technical field [0001] The invention belongs to the technical field of crop substrates, and specifically relates to a soilless cultivation substrate for wheat. Background technique [0002] Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A. Due to different varieties and environmental conditions, the nutritional content is quite different. In terms of protein content, wheat grains grown in continental arid climate regions are hard and transparent, with high protein content of 14-20%, strong and elastic gluten, suitable for baking bread; wheat grains born in humid conditions The protein content is 8-10%, the grain is soft, and the gluten is poor. It can be seen that the influence of geographical climate on the formation of the product is very important. [0003] Soilless cultivation refers to a cultivation method that does not use natural soil but uses substrate or nutrient solution for irrigation. It is mainly applied to ve...

Problems solved by technology

[0005] In recent years, the research on wheat soilless seedling cultivation mostly uses rice straw or straw as the main raw material of the substrate, and the specific gravity of the substrate is relatively light, and there are problems such as poor water retention capacity when seedlings are watered, straw and straw are easy to float, and seedlings are easy to float when transplanting.

At the same time, its manufacturing process is relatively complicated and the cost is high.

During the seedling raising period, the frequency of fertilization is increased, which makes the operation complicated. These are not in line with the simple and efficient farming concept of today's farmers, so it is not easy to popularize and use

Since fresh vinegar residue contains a lot of organic acids and microorganisms, it is not resistant to storage, it is easy to rot and deteriorate for a long time, pollutes the environment, and becomes an organic waste that is difficult to digest and process for vinegar production enterprises
