Drip irrigation system
1. The feed liquid pipeline system
Reasonable of micro-irrigation system, need to be able to make the range of a pipeline branch control as part of the irrigation uniformity, and its system design for hydraulic fluid for calculation of the basic premise.Throughout the system, has the certain pressure water from the main and branch pipe, capillary, drop head out of the country, but each outlet water pressure is different, the farther from the water, power tube diameter is fine, the greater the hydraulic loss, due to the drop flow has a certain relationship with the pressure of the head, uneven pressure difference each drop head water yield.By increasing the tube diameter, reducing water and pipe wall friction caused by hydraulic loss, can improve the uniformity of the irrigation district, but the greater the diameter, the more coarse investments.So in the homogeneous degree of the irrigation district (85%), the above cases, should be the reasonable design, proper select main and branch pipe and capillary diameter, decrease as far as possible.The other set up the system and fertilizer filter.
2. The nutrient solution for fluid system
This system is applicable to solid substrate cultivation techniques.Can be divided into the circulating fluid supplying system with water the liquid type (open) for the liquid system.
