Abstract: Some experiments of indeterminate growth crops were carried out on tomato R144, R139 and net melon C-8 under Deep Flow Technique conditions. Some special methods, such as temperature and humidity control, nutrient solution control and growing process and trunk form control were developed and applied. The experimental single plant of R144 tomato by deep flow technique under controlled environment in the greenhouse bore over 13 550 tomato fruits, and kept on blooming and bearing. Thirty-six ripe melons were harvested from the tested single plant of C-8 net melon under the same conditions. The experimental results showed that this technique could make full use of hereditary potentials of crops to produce high quality and high-yielding products under controlled circumstances. Some of these results could provide reference for practical production of greenhouse crops.
