What are the advantages of soilless cultivation in multi-span greenhouses?
Soilless culture is characterized by artificially created crop root growth environment instead of soil environment, it can not only meet the needs of crops for nutrients, water, air and other conditions, but also control and adjust these conditions to promote the growth of crops, and Achieving a better camp growth balances reproductive growth. Therefore, the crops of soilless culture usually grow well and develop well, with high yield and high quality.
Soilless culture has the characteristics of water saving, fertilizer saving and high yield. Various nutrients required by crops in soilless culture are artificially formulated into nutrient solution for application, with less water loss, balanced nutrient components, and high absorption efficiency. Crop species and different growth stages of the same crop, supply nutrients scientifically. Therefore, the crops grow robustly and have strong growth potential, which can give full play to the potential of increasing production.
It is clean, hygienic and pollution-free. Organic fertilizer is applied in soil cultivation, and the fertilizer is decomposed and fermented, which produces odor and pollutes the environment. It will also cause the eggs of many pests to breed and harm crops. However, soilless cultivation uses inorganic fertilizers, which do not have these problems. It can avoid the pollution of harmful substances such as heavy metals in the contaminated soil.
Soilless cultivation saves labor and effort, and is easy to manage. Soilless cultivation does not require cultivating, ploughing, weeding, etc. Watering and topdressing can be solved at the same time, and the liquid supply system is regularly and quantitatively supplied, which is convenient for management, does not cause waste, and greatly reduces the labor intensity.
