Organic environment-friendly soilless culturing method

Abstract

An organic environment-protecting soilless culture novel method comprises the following content: in certain protection facilities, to build planting groove and drip irrigation facilities, then to add the medium by high temperature fermentation into 25 percent solid organic fertilizer mixing fully and filling in the groove, and to increase fertilizer and water control management of planting crops. The present invention is based on our soilless culture practical experience, after numerous exploration and improvement, selected an organic new environment-protecting soilless cultivation method. The method utilizes cotton seed hulls, barks, sawdusts, parings, sunflower stalks, corn stalks, sands, slags, pot ales and mushroom residus cheapness material as culture medium, utilizes getting easily organic fertilizer and inorganic fertilizer as fertilizer, it not only has traditional soilless culture features, but also lump sum investment of soilless culture system decreases 60 percent compared with nutrient solution in soilless culture, fertilizer cost decreases 60 percent, yield improves 10 percent to 20 percent, and its operating management is simple, discharging liquid of this system is no pollution, and the product quality is good.

Description

Technical Field: [0001] The invention relates to a new method for organic environmental protection soilless cultivation Background technique [0002] Soilless cultivation can effectively avoid soil-borne diseases and insect pests and continuous cropping obstacles, which is one of the main problems in greenhouse production. At present, it is difficult to find a piece of unpolluted land in the suburbs of big cities. The soilless cultivation substrate is artificially prepared, with good physical properties, saving water and fertilizer, and can increase crop yields. It is not suitable for general agricultural cultivation. It can produce crops in different areas while reducing labor intensity, and can produce clean, sanitary, pollution-free, pollution-free, and high-quality products. [0003] However, because the environment (nutrient solution or solid substrate) of soilless cultivation crops has a smaller buffering capacity than soil, the root system is easily affected by external co...

Problems solved by technology

[0003] However, since the environment (nutrient solution or solid substrate) of soilless cultivation crops has a smaller buffer capacity than soil, the root system is easily affected by external conditions such as temperature in the facility, pH of nutrient solution, and nutrient status, so it is easier than soil cultivation. Physiological obstacles occur, and corresponding countermeasures are urgently needed to overcome them in production

In view of the fact that the soilless cultivation method adopted in most areas of our country is still dominated by inorganic energy-consuming type, it not only consumes a lot of energy, pollutes the environment, but also produces food with excessive nitrate content, which will cause great harm to the human body, so efforts should be made to Promote the new method of organic and environment-friendly soilless cultivation with the advantages of low investment, low cost, less labor, easy operation, high yield and high quality of products
