Description

Technical Field

[0001] The invention relates to the technical field of fruit tree seedling cultivation, in particular to a nutrient solution drip irrigation device for forestry fruit tree seedling cultivation. Background Art

[0002] Fruit tree seedlings refer to artificially cultivated fruit tree seedlings, usually cultivated in nurseries, with root systems and seedling trunks. During seedling cultivation, nutrient solution needs to be drip-irrigated to the seedlings to ensure that the seedlings have sufficient nutrition. The nutrient solution usually needs to be moved in the nursery by a cart to drive the storage and infusion system for drip irrigation to ensure that the nutrient solution fully irrigates each seedling. The existing drip irrigation device can ensure the area and efficiency of drip irrigation, but it is difficult to adjust for seedlings of different types and heights. The device is easy to contact with the seedlings, causing the seedlings to fall over, affecting the growth of the seedlings.

[0003] The patent with the announcement number CN218526773U discloses a nutrient solution drip irrigation device for fruit tree planting, which includes a box, a drip irrigation mechanism and an auxiliary mechanism. The bottom of the box is fixedly connected with a support plate A, the drip irrigation mechanism is arranged on the box, and the drip irrigation mechanism includes a water pump fixedly installed on the top of the box. The water inlet pipe of the water pump is fixedly connected with a three-way pipe A, the water outlet end of the water pump is fixedly connected with a connecting pipe, one end of the connecting pipe is fixedly connected with the three-way pipe A, the two ends of the three-way pipe A are respectively fixedly connected with the delivery pipe, one end of the delivery pipe is fixedly connected with the three-way pipe B, and the two ends of the three-way pipe B are fixedly connected with the three-way pipe A. They are fixedly connected with hoses respectively, and the auxiliary mechanism is also arranged on the box body. The auxiliary mechanism includes a U-shaped plate fixedly connected to both sides of the box body. The four groups of nozzles are arranged to make the drip irrigation more efficient, and the positions of the four groups of nozzles can be adjusted, thereby enhancing the flexibility of the drip irrigation of fruit trees. Although this patent solves the above problems, it is still difficult to perform three-dimensional adjustment. When the height of the seedlings is high, it is easy to affect the movement of the device. Forcibly moving the device is easy to bend the seedlings, and the flexibility needs to be improved. Therefore, a forestry fruit tree seedling nutrient solution drip irrigation device is proposed to solve the above problems. Summary of the invention
