抄録

In this study, a new cultivation system using porous ceramic pipes with negative pressure was successfully developed, by which the water content of soil could be auto-controlled to suitable values for vegetable growth. In this cultivation system, the nutrient and water can be autosupplied to roots continuously and timely, when necessary. The response of the soil pF to the inner negative pressure of the ceramic pipe and its irrigation rate were also studied. During cultivation experiment of lettuce, the soil pF of the new system could always be maintained at suitable values (1.3-1.5) for the growth of lettuce, while the pF in the usual soil cultivation fluctuated widely (0-1.9). The growth and yields of lettuce cultivated in the new system were significantly better than that in the usual soil culture. The developed cultivation system would be a useful and practical technique for vegetable production.
