Abstract: On the basis of synthesizing various nutrient solution doses of tomato culture, national and abroad, and according to the qualities of water in Beijing and the unconventional culture, a new kind of the nutrient solution doses under the unconventional culture of infinitive-growth-typed cultivated by deep nutrient solution flow was formulated. According to different qualities during different periods of tomato growth and development, the components, concentration, acidity-alkalinity, etc. in nutrient solution were adjusted, and a dynamic management to the flow was carried out. The results of the planting experiments showed that the various nutritive components (N, P, K, Ca, Mg, etc.) in the dose could be balancedly absorbed by tomato, and that the dose was nutrition-balanced.
