[0002] Greenhouse fruit and vegetable cultivation refers to the transfer of crops such as fruits and vegetables from outdoor planting to indoor greenhouses, and the control of temperature and humidity in the greenhouses, which can not only ensure that the fruits and vegetables are in a comfortable growing environment, but also centrally manage the fruits and vegetables in the greenhouses, including watering and fertilizing, etc., to avoid the impact of bad weather on fruit and vegetable crops, improve the survival rate of crops, increase crop yields, and increase economic benefits. When transferring crop seedlings to greenhouses for planting, the seedlings need to be cultivated first, and the seedlings can be transferred after they grow to the stage where they can adapt to the environment. The cultivation of seedlings is mostly achieved by seedling equipment. The seedlings to be cultivated will be cultivated in seedling pots, and the seedling pots will be placed on the cultivation racks for Centralized cultivation, light control, temperature and humidity control, and irrigation control are carried out. In order to ensure that the fruit and vegetable seedlings can obtain sufficient water, an irrigation nozzle is generally installed above a single seedling pot to ensure the water supply through independent irrigation methods.
