Description

Foliar fertilizer spraying device is planted to tea-oil camellia

Technical Field

The utility model relates to the technical field of spraying devices, in particular to a tea-oil camellia planting foliar fertilizer spraying device.

Background

The tea-oil tree belongs to the tea family and is evergreen small arbor. The seeds can be used for pressing oil (tea oil) for eating, so the tea oil is named. The tea oil has clear and fragrant color, rich nutrition and long storage life, and is high-quality edible oil; can also be used as lubricating oil and rust-preventive oil for industry. The tea cake is not only a pesticide, but also a fertilizer, and can improve farmland water storage capacity and prevent and treat rice field pests. The pericarp is the raw material for extracting tannin extract. In the planting process of the oil tea, fertilizer needs to be sprayed besides root fertilization;

the existing water solvent spraying device generally pours the water solvent into a water tank directly, then pumps the water solvent into a spray head for spraying by a water pump, and the water solvent is directly placed in the water tank, so that the water solvent is insufficiently mixed with water, and the situation of uneven nutrition of fertilizer at a spraying position is caused;
