Agricultural irrigation system
Technical Field
The invention relates to the technical field of water collection irrigation, in particular to an agricultural irrigation system.
Background
Technical measures for supplementing the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yield, the crops must be supplied with sufficient moisture. Under natural conditions, the water requirement of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, irrigation must be done manually to compensate for the lack of natural rainfall. The world is increasingly short of fresh water resources, and the demand of human beings on food is continuously increased, so that the fresh water resources become the security threats for agricultural development and world food supply. The key point is to solve the problems of limited cultivated land area, shortage of fresh water resources and rising of world grain demands. In regions where water resources are scarce, many farmable fields are located in hills, where water sources and streams are far away, and it is often necessary to build penstocks or use water pumps, but even so, it is not satisfactory. Many plants are irrigated "by the weather", and if they do not rain for a long time, they are usually low in yield or never harvested. Therefore, the demand for the water collecting device is very urgent, and particularly, the water collecting device which can collect dew at night is necessary.
Patent 201410750485.6 discloses a retaining and intelligent irrigation equipment of setting in the gardens, and usable rainwater carries out treegarden irrigation. The device can only collect rainwater, can not collect fog, can only eat by the day, and has limitation.
Patent 201310598099.5 discloses a mist water collecting device capable of collecting moisture in mist water, but it is limited in that the structure can be designed only for small devices, and its mist water collecting area is small, and it is easy to accumulate impurities.
Therefore, a collecting device which can collect fog, has strong collecting capacity and does not accumulate sundries and can be matched with a drip irrigation pipe for irrigation is needed.
