Problems solved by technology
[0002] With the improvement of the level of agricultural development, the corresponding various supporting facilities are constantly improving. The most notable ones are the cultivation and harvesting of crops, but there is little improvement in the irrigation equipment needed for the growth of crops.
[0003] The commonly used irrigation methods are: 1. After pumping, the crops concentrate on absorbing water; 2. Artificial irrigation; the first method is obviously not suitable for seedlings in the greenhouse, because the root system of the seedlings is not developed enough, and the irrigation volume is not easy to control; The second method is not suitable for a large number of seedlings

The invention discloses an in-greenhouse seedling irrigation system, which comprises a plurality of irrigation channel units. Each irrigation channel unit is provided with a plurality of irrigation water outlets, each irrigation water outlet is connected with an electromagnetic valve, the multiple electromagnetic valves on each irrigation channel unit is connected with a relay, and the multiple relays are connected with a control terminal in connection with a humidity sensor. The multiple irrigation channel unit is connected with a main pipeline, and the main pipeline is connected with a watertower through a water pump. The control terminal controls on and off of the electromagnetic valves through the relays to realize automatic control of the irrigation system, and the irrigation systemcan be closed according to soil humidity by the aid of the humidity sensor. Aiming at small greenhouse space and unsuitableness of excessive irrigation of weak seedlings, the irrigation method has advantages of high operability, low cost and high efficiency by reasonable arrangement.
Description
technical field [0001] The invention belongs to the technical field of seedling irrigation equipment, and in particular relates to a seedling irrigation system in a greenhouse, and also relates to a seedling irrigation method in a greenhouse. Background technique [0002] With the improvement of the level of agricultural development, the corresponding various supporting facilities are constantly improving. The most notable ones are the cultivation and harvesting of crops, but there is little improvement in the irrigation equipment needed for the growth of crops. [0003] The commonly used irrigation methods are: 1. After pumping, the crops concentrate on absorbing water; 2. Artificial irrigation; the first method is obviously not suitable for seedlings in the greenhouse, because the root system of the seedlings is not developed enough, and the irrigation volume is not easy to control; The second method is not suitable for large numbers of seedlings.
