Description

Nursery Smart Watering System

technical field

The invention belongs to watering equipment, and mainly relates to an intelligent watering system for a nursery.

Background technique

During the seedling raising period in the nursery, it is essential to irrigate the seedlings. The most widely used irrigation method in the nursery is sprinkler irrigation, but there are still some disadvantages in the existing sprinkler irrigation method. For example, the publication number is CN216362993U, and the name is a timing automatic irrigation device for nursery In the process of sprinkling the seedlings, part of the water will be evaporated, which increases the consumption of water sources. In addition, the design of the timing sprinkling irrigation, when it is impossible to judge whether the seedlings are short of water, the timing sprinkling irrigation of the seedlings may cause the seedlings Excessive watering or insufficient watering lead to death; there are also soil moisture sensors to monitor soil moisture, as the publication number is CN 210746492 U, and the name is called an automatic moisture sensing watering device to determine the watering time. On the one hand, soil moisture It is not possible to accurately determine whether it is in a state of water shortage, because it is affected by seasonal changes and natural climate changes, the evaporation of water is different, and the water demand of plants is different, so it is impossible to accurately determine the water demand (watering) Water resources cannot be reasonably allocated at the time point; on the other hand, different growth times have different water demands. Therefore, it is unscientific and inaccurate to determine the watering time solely by soil moisture. , this device utilizes the plant leaf wilting equipment erected in the air to detect the water shortage state of the plant, but the existing aerial equipment cannot operate independently, such as the publication number is CN 212065098 U, named as a greenhouse seedling cultivation irrigation device , resulting in a complex structure, many components, and many failures. At the same time, the existing moving mechanism has no guide mechanism, which causes severe wear and tear of parts.
