摘  要：
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
