This technique has developed for more than 150 years, and plays an essential role in promoting the development of horticultural, agricultural and forestal production, as well as agricultural modernization. Substrate and nutrient solution formulae and their application are the core of soilless culture technique. Based on the classification system of soilless culture, the types, advantages and scope of application of substrate formulae for growing vegetables and flowers in soilless culture, as well as the types, advantages and scope of application of nutrient solution formulae, and the regulation of nutrient solution ingredients are first systematically summarized in this paper; then, the advantages and disadvantages of the inorganic energy-intensive soilless culture and eco-organic soilless culture, and their scopes of application are analyzed; finally, research directions for further perfecting soilless culture technique are presented, and the outlook for the application of soilless culture is also provided.展开更多

The mixed substrate soilless cultivation techniques developed by the Beijing Agricultural Technology Extension Station for mini watermelon in spring greenhouse can effectively solve the problem of continuous cropping in facility wa- termelon, and they are conducive to green, safe and efficient development of water- melon industry for fixed nutrient solution formula, automatic water and fertilizer irri- gation, stable product quality and facilitating large-scale and standardized production.展开更多
