Soilless cultivation techniques in greenhouse

Soilless cultivation in greenhouse means that crops are not cultivated in soil, but in mineral-soluble nutrient solution. This technology has the advantages of water saving, fertilizer saving, high yield, cleanliness, no pollution, labor saving, easy management and so on. As long as there are certain cultivation equipment and management measures, crops can grow normally and obtain high yield.

Advantages of soilless cultivation in greenhouse

1. Save water, fertilizer and high yield

In soilless cultivation, all kinds of nutrient elements needed by crops are artificially prepared and applied into nutrient solution, with less water loss, nutrient balance, high absorption efficiency, and according to crop species and different growth stages of the same crop. supply nutrients scientifically. Therefore, the crop growth and development is robust, the growth potential is strong, can give full play to the potential to increase production.

2. Clean, hygienic and pollution-free

The application of organic fertilizer in soil cultivation, fertilizer decomposition and fermentation will not only pollute the environment, but also cause the eggs of many pests to breed and harm crops, while soilless cultivation uses inorganic fertilizers, which does not exist these problems. and can avoid the pollution of heavy metals and other harmful substances in the contaminated soil.

3. Save labor and labor and be easy to manage

Soilless cultivation does not require ploughing, ploughing, weeding and other operations, saving labor and labor. Watering and topdressing is solved at the same time, and is supplied regularly and quantitatively by the liquid supply system, which is convenient for management, will not cause waste, and greatly reduces the labor intensity.

4. Avoid continuous cropping obstacles

In the field planting management of vegetables, reasonable land rotation and avoiding repeated cropping in successive years is one of the important measures to prevent the serious occurrence and spread of diseases. Soilless cultivation, especially hydroponics, can fundamentally solve this problem.

5. Not subject to the restrictions of regional seasons

Soilless cultivation makes crops completely out of the soil environment and is not limited by soil quality and water conservancy conditions. soilless cultivation can be used in many deserts, wastelands or areas where it is difficult to cultivate. Get rid of the constraints of the land, soilless cultivation can also be free from space restrictions, the use of urban abandoned factories, buildings on the flat roof to plant vegetables and flowers, have virtually expanded the cultivation area.

6. Conducive to the realization of agricultural modernization

Soilless cultivation makes agricultural production get rid of the restriction of natural environment and can be produced according to people's will, so it is a mode of production of controlled agriculture. Farming according to the quantitative index to a large extent is conducive to the realization of mechanization and automation, thus gradually moving towards the industrialized mode of production.
