The Advantages Of Soilless Cultivation

Soilless culture refers to the cultivation technology that uses substrate, water, and nutrient solution containing essential elements for plant growth and development to provide nutrients without natural soil, so that plants can normally complete the entire life cycle. It greatly expands the space for agricultural production, so that crops can be produced without relying on soil, and the development prospects are very broad.

1. Effectively prevent soil continuous cropping obstacles and soil-borne diseases. In the field planting management of vegetables, reasonable land rotation and avoiding continuous cropping are one of the important measures to prevent the serious occurrence and spread of diseases. However, in recent years, the area of cultivated land in our country has been decreasing year by year, and vegetable production has gradually become specialized and large-scale, especially the protected cultivation area has been expanded year by year, making it difficult for the reasonable rotation system of land to be further promoted and applied. Soil diseases caused by continuous cropping of land are becoming more and more serious. Although soil disinfection can also be solved, soil disinfection is not only costly, labor-intensive and drug-intensive, but also the effect is not very ideal. If the soilless culture method is adopted, because its cultivation environment is completely isolated from the soil, it can effectively prevent the occurrence of soil-borne diseases.

2. Improve the yield and quality of crops. Using soilless cultivation technology can artificially control the temperature, light, moisture, nutrient elements and other environmental conditions required by crops, so it has higher yield than conventionally produced vegetables, better quality, and clean and hygienic products. Good economic benefits. Since soilless culture does not use organic fertilizers, the pollution of products by parasites of organic fertilizers in the soil can be avoided, and diseases rarely occur.

3. Water-saving, fertilizer-saving, and labor-saving In the cultivation process, management links such as seedling preparation, soil tillage, watering, intertillage weeding, and pest control can be omitted, which can save a lot of labor. Mechanized operations and automated management can also be implemented in soilless cultivation sites with a certain scale. The nutrient solution in soilless culture can be formulated and adjusted according to the nutritional needs of different crops in each growth period. The nutrients can be directly absorbed by the crops without going through the soil, and the unabsorbed part can be recycled and reused, while reducing Water waste caused by soil evaporation and loss.

4. The location of soilless cultivation not restricted by natural conditions is not restricted by soil quality and water conservancy conditions, especially in deserts, barren land, drought and other areas with harsh conditions. It is an effective crop cultivation method.
