Soilless culture substrate special for strawberries

Abstract

The invention discloses a soilless culture substrate special for strawberries and belongs to the field of a soilless culture technology. The substrate comprises the following components in volume ratio: 25-40% of vinegar residue, 10-20% of manioc waste, 10-25% of grass carbon, 10-25% of vermiculite and 5-15% of plant ash; as for the substrate, the water content is 25-45%, the total porosity is 65-85%, the content of organic matters in a dry substrate is more than or equal to 25%, the content of total nutrients is 2-4%, the EC (Elasticity Coefficient) value is 0.5-1.0mS / cm and the pH value is 5.5-7.0; and the substrate is grain solid with dark brown or black brown appearance and has no peculiar smell. According to the special soilless culture substrate, organic wastes including the vinegar residue, the manioc waste and the like are mainly utilized as raw materials and are subjected to high-temperature fermentation treatment to produce the soilless culture substrate, so that the special soilless culture substrate changes wastes into valuable things and turns harm into good. The soilless culture substrate special for the strawberries disclosed by the invention is loose in texture, abundant in nutrient content and high in organic matter content, is non-toxic and harmless, has no weed seeds and contains microbial flora; and the disease resistance of strawberry plants can be improved and the special soilless culture substrate can be widely applied to soilless culture including groove culture, bag culture and the like of the strawberries.

Description

technical field [0001] The invention relates to a soilless cultivation substrate for crops, in particular to a special soilless cultivation substrate for strawberries, and belongs to the technical field of soilless cultivation. Background technique [0002] Soilless cultivation refers to the method of irrigating cultivation with substrate or nutrient solution without using natural soil. It is mainly used in the cultivation of crops such as melons, fruits, vegetables or flower seedlings. It is a high-yield, high-quality and advanced method that saves water, fertilizer and labor. Technology, this technology originated in the middle of the 19th century, and 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] Substrate cultivation is the method with the large...

Problems solved by technology

However, peat is produced in the Northeast, resources are tight, and cannot be regenerated. Enterprises in Jiangsu use peat at high cost; although animal manure is rich in nutrients, it has a small amount and is difficult to collect. It is difficult to meet the needs of factory cultivation.

However, there are a large number of vinegar grains in my country's vinegar production enterprises, which are relatively rich in organic matter content, but the utilization methods are not very extensive. Literature search found that there have been reports on the use of vinegar grains to produce vegetables and nursery stock cultivation substrates in China, and the production of vinegar grains as the main raw material Strawberry-specific matrix, there is no relevant report in China
