Simple efficient soilless culture technique

Abstract

Soilless culture mainly comprises the steps of preparing a nutrient solution for plant growth with chemical reagents according to the nutrient elements required for plant growth, and fixing plants, wherein the supporting facilities for the nutrient solution, including a distribution system, a circulating system, a monitoring system and the like are needed, the unit area investment is large, the operation is difficult, the product cost is high, so that the soilless culture is not suitable for real production. The existing soilless culture is mainly used for sight-seeing. An all-round nutrient-enriched matrix is in need, which has complete, rich and balanced nutrients, good permeability and high water retention and is prepared from agricultural production waste such as renewable sawdust, straws, bran residues, mushroom residues, pig manure, chicken manure, cattle manure and coal ash, to replace prepared chemical nutrient solution for proving nutrients to plants, and at the same time, the plants are fixed and soilless culture is carried out, so as to reduce equipment and facility investment of soilless culture, reduce operation links, reduce production cost and improve product quality, which is the crucial points and purposes of the invention.

Description

Technical field [0001] The simple and efficient soilless cultivation technology belongs to agricultural crop cultivation, plant nutrition and facility agriculture. technical background [0002] Soilless cultivation is the main method of factory agriculture. All the nutrients needed for plant growth are provided by artificial preparation of chemicals. It is necessary to establish a firm culture tank to hold the nutrient solution and plants, and the plants need to be used in the culture tank. Foam board, stone sand, ceramsite, perlite, vermiculite or rock wool, etc., these fixing materials cannot provide nutrition for plants, but it costs a lot of money, and at the same time, the nutrient solution needs to be pumped out by distributors and circulation pumps. It is recycled in the cultivation tank, and 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 ...

[0002] Soilless cultivation is the main method of factory agriculture. All the nutrients needed for plant growth are provided by artificial preparation of chemicals. It is necessary to establish a firm culture tank to hold the nutrient solution and plants, and the plants need to be used in the culture tank. Foam board, stone sand, ceramsite, perlite, vermiculite or rock wool, etc., these fixing materials cannot provide nutrition for plants, but it costs a lot of money, and at the same time, the nutrient solution needs to be pumped out by distributors and circulation pumps. It is recycled in the cultivation tank, and 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 from the cultivation tank to cause waste and environmental pollution. In this way, soilless Cultivation must be carried out in intelligent greenhouses 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, and the product cost is high. The nutrient solution is prepared with chemicals to support plants. Product quality decline
