Ebb and flow table is a mature agricultural irrigation technology, which has been widely used in developed countries. It solves the contradiction between irrigation and oxygen supply well, and irrigation basically does not destroy the "three-phase" composition of substrate, so it is an efficient agricultural technology.
1, Ebb and flow table has water-saving, completely closed system cycle, can achieve more than 90% of the utilization rate of water and fertilizer;
2. Ebb and flow table irrigation crops is fast, and the seedling age per week is at least 1 day earlier than that of traditional seedling raising method, which improves the utilization rate of facilities;
3. Ebb and flow table avoids water film on plant leaves, makes leaves receive more light and photosynthesis, and promotes transpiration to absorb more nutrients from roots;
4. Ebb and flow table can provide stable moisture content of root matrix and avoid the death of capillary roots due to drought near the edge and bottom of the container;
5, Ebb and flow table makes the relative humidity easy to control, can keep the crop leaf surface dry, reduce the use of chemicals;
6, Ebb and flow table cultivation bed is very dry, no weed growth, can reduce the breeding of fungi;
7, Ebb and flow table can reduce the management cost, even if the manual operation of nutrient solution management, a person can also be completed within 20-30min 0.2h㎡• around the hole disk seedling irrigation;
8,Ebb and flow table can be used at any time, not limited by varieties, specifications, time
