Soilless cultivation technology is favored by the majority of growers by virtue of saving water and fertilizer, high yield and no pollution, quick investment, low investment risk, no regional restrictions, simple operation and easy management, and full use of space. The preferred scientific method of planting for crops. So what is soilless cultivation? How much does it cost to grow soilless? Which vegetables can be cultivated without soil? Wait a minute, the following small series will explain these soilless cultivation problems one by one. 1. What is soilless cultivation technology? Soilless cultivation can also be called nutrient solution cultivation and hydroponic cultivation. It is different from previous techniques of cultivation in soil. It is planted in a mineral-dissolved aqueous solution (nutrient solution) or planted in a certain Crop cultivation with nutrient solution in the cultivation substrate, so that the crop can complete the whole growth cycle normally. It is a new crop cultivation technology popularized in recent decades. Because no natural soil is used, the nutrient solution is used to cultivate the crop. Therefore, it is called soilless cultivation. Second, how much does it cost to cultivate without soil? Soilless culture technology has the characteristics of quick investment, quick cycle, short-term one-time investment, and the main investment is to build a greenhouse. For the construction price of greenhouses and the cost of materials, it is determined according to the specific conditions. Generally, the cost of greenhouses for greenhouses is about 5000-6000 per 667m2, the cost of greenhouses for greenhouses is about 8000-9000 per 667m2, and the greenhouse for greenhouses is 667m2. The cost is about 10,000-15,000, and the cost per 667m2 of a standard solar greenhouse is about 40,000-50000. If you grow vegetables, you can go on sale in 30 days. Third, the common mode of soilless cultivation techniques 1. Hydroponics concept Hydroponics can also be called nutrient liquid culture. It is mainly a soilless cultivation technique in which the root of the crop is directly immersed in the nutrient solution, and the nutrient solution is used instead of the soil to provide the nutrients and moisture needed for the growth of the crop. 2, substrate culture Matrix culture can also be called solid substrate cultivation, mainly using a solid substrate to fix crop roots, a soilless cultivation technique that allows crops to absorb nutrient solution and oxygen through a substrate by watering nutrient solution or applying solid fertilizer. 3, circulating rock wool training After the nutrient solution is dripped into the rock wool by drip irrigation, the excess nutrient solution will not be removed, but will flow back to the underground sump through the return pipe for recycling. 4, open rock wool training The nutrient solution is dripped into the rock wool planting mat by drip irrigation, and the excess nutrient solution is discharged from the bottom of the rock wool planting mat and discharged to the outside. 5, fog training The mist culture is also called aerosol cultivation. The water is formed into a mist by strong pressure and sprayed directly onto the roots of the crop to provide water and nutrient requirements for crop growth. 4. Which vegetables can be cultivated without soil? 1, tomato Tomatoes can be cultivated without soil in all seasons. Generally, the soilless greenhouse tomato is cultivated without soil. When the greenhouse is cultivated, the greenhouse performance should be determined specifically. The tomato is mainly produced in winter and spring. 2, bitter melon Bitter gourd, bitter gourd, bitter gourd, fruity and bitter, mainly used as vegetables, can also be used as sugar stains, planted in the north and south, not high requirements for cultivation environment, with strong growth potential, strong fruit setting ability, long harvest time Other advantages, very suitable for soilless cultivation. 3, eggplant In recent years, most of the eggplant cultivation has been carried out in greenhouses and greenhouses. However, soil-borne diseases have become more and more serious because of repeated cropping, and soil-borne diseases can be overcome by soilless cultivation techniques. 4, ginger The traditional planting mode, because continuous cropping leads to more soil residues, can not remove the pathogen of the ginger mites, resulting in the infection of ginger rickets during the growing process, and the use of soilless cultivation techniques can effectively solve this problem. 5, cucumber Cucumber planting process is vulnerable to pests and diseases, and the use of soilless culture technology not only effectively avoids pests and diseases, soil infection, but also reduces the amount of pesticides used, provides crop quality and yield, has fertilizer and labor, is not restricted by land fertility, etc. Advantage. Five, the advantages of soilless cultivation 1, regardless of seasonal restrictions, you can plant a variety of crops throughout the year. 2, soilless cultivation technology can monitor and adjust the nutrition in the water to meet the needs of crop growth, precise control of plant growth, avoiding length. 3. In the hydroponic system, the water in hydroponics can be recycled and reused, which can reduce the amount of water used and save water. 4. Soilless cultivation of crops does not require the use of chemical agents, fertilizers, etc., to provide a sterile environment for crop growth. 5. Soilless cultivated crops grow fast, increase in yield, have no trouble in soil setting and testing, and make full use of space. 6. Compared with traditional cultivation methods, soilless cultivated crops have 50% more vitamins than traditional cultivation and have very high nutritional value. The above is the content of soilless cultivation techniques compiled by Xiaobian. Compared with some developed countries, the soilless culture technology in China is still in the primary development stage, and the future development of soilless culture is huge. Many crop varieties can be used without soil. The cultivation technology increases production and income. Therefore, according to China's national conditions, it is necessary to select soilless cultivation techniques with Chinese characteristics, such as simple and convenient installation, low investment, low cost, convenient application and good effect. Xiaobian believes that with the continuous advancement of science and technology, Chinese characteristics Soilless culture technology is just around the corner!
