Description

A kind of intelligent drip irrigation equipment and drip irrigation method

technical field

The invention relates to the field of agricultural technology, in particular to an intelligent drip irrigation device and a drip irrigation method.

Background technique

In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. The commonly used irrigation methods are flood irrigation, spray pipe and drip pipe. Flood irrigation is mainly to dig ditches on the edge of the field, then introduce water into the ditch, and then lead the water in the ditch into the field. The method of flood irrigation is a waste of water resources, and the irrigation is uneven, which will easily lead to the rise of groundwater and the salinization of the land. . Sprinkler irrigation is to send water to the sprinklers in the field by pipes. There are differences between high pressure and low pressure, and it can also be divided into fixed and mobile. The disadvantage of sprinkler irrigation is that a lot of water will be lost due to evaporation, especially in windy weather, and it is not easy to irrigate the entire irrigated area evenly. Water remaining on the leaves will easily cause mold to multiply. Hot, sunny weather can cause leaf burn. Drip irrigation is a form of irrigation that drips water drop by drop, evenly and slowly, into the soil near the plant roots. The drip flow is small, and the water drops slowly into the soil, which can minimize evaporation loss. If mulch is added, it can be further reduced. Evaporation, under drip irrigation conditions, except that the soil moisture immediately below the dripper is in a saturated state, the soil moisture in other parts is in an unsaturated state, and the soil moisture mainly infiltrates and diffuses by means of capillary tension. Compared with various methods, the dropper method saves water resources more and can maximize the utilization rate of water or other business substances. The current dropper equipment simply lays pipes in the soil and then uses water to irrigate. This method has no basis at all, and it depends on manual judgment whether the amount of water is sufficient, resulting in plants not being in the best water replenishment state.
