Efficient and organic ecological soilless culture method

Abstract

The invention discloses an efficient and organic ecological soilless culture method. The efficient and organic ecological soilless culture method is characterized in that a nutrient substance is produced by utilizing reproducible agricultural production waste, wherein the component percentage and production method are as follows: mixing two or more of straws, saw dust, bran, waste mushroom slag, rice husk, bagasse and coconut shell; adding dry cow dung, dry pig manure, dry chicken manure, pure phosphorus and pure potassium per each cubic meter of the mixture; adding water for stacking transformation; adding coal ash after the stacking transformation so as to produce the nutrient substance. The efficient and organic ecological soilless culture method is simple and convenient to operate, and easy to manage, only needs one-time investment, and can produce the nutrient substance which is complete and rich nutrition and reasonable as well as coordinate in proportion through processing reproducible agricultural production waste; soiless culture can be carried out on the existing common melon and vegetable greenhouses. Therefore, the soiless culture which huge investment, high cost and rigorous management becomes simple and practicable, is convenient and fast in operation, and can be mastered by everyone and carried out at any place.

Description

Technical field [0001] The invention relates to agricultural crop cultivation technology, in particular to a high-efficiency organic ecological soilless cultivation method. Background technique [0002] With the economic development of our country, a large number of rural population has poured into cities and towns, and the sharp reduction of rural arable land, population transfer, and rapid aging of labor have laid huge hidden dangers for the production and supply of agricultural products. At the same time, producers have used a lot of pesticides and fertilizers in pursuit of production. The produced vegetables, melons and fruits contain excessive nitrate content and high pesticide residues, which seriously endanger people's health. In the face of these two increasingly prominent contradictions, traditional planting methods cannot be resolved at all. The nutrient solution soilless cultivation not only requires a lot of investment, but also has a difficult operation and managemen...

Problems solved by technology

[0003] All the nutrients needed for the growth of plants in soilless culture are provided by artificial preparation of chemicals. It is necessary to establish a firm culture tank to hold the nutrient solution and the plants. The plants also need foam boards, stones, sand, Ceramsite, perlite, vermiculite or rock wool, etc., these fixing materials cannot provide nutrition for plants, but it costs a lot of money. It is necessary to use pH and conductivity automatic devices to control the pH and salt concentration of the nutrient solution. When the salt reaches a certain level, it must be discharged. To carry out soilless cultivation in this way, it must be in an intelligent greenhouse with temperature control, humidity control and light control. The investment per unit area is huge, the nutrient solution and energy consumed in production are large, the product cost is high, and the nutrient solution is prepared with chemical agents to support plants, and the quality of the produced products decreases.

If soilless cultivation continues to use nutrient solution and purified fertilizer agriculture, its development prospects are very slim
