Description

Water and fertilizer integrated device for oil tea planting with fertile leaf back surface

Technical Field

The invention relates to the technical field of camellia oleifera planting, in particular to a camellia oleifera planting water and fertilizer integrated device with the back of leaves receiving fertilizer.

Background

Camellia oleifera belongs to Theaceae, and is a evergreen small arbor. Its seed can be used for extracting oil (tea oil) for eating, so its name is. The tea oil is clear in color, delicious, rich in nutrition and long in storage life, and is high-quality edible oil; can also be used as lubricating oil and antirust oil for industry. The tea cake is not only a pesticide but also a fertilizer, and can improve the water storage capacity of the farmland and prevent and control pests in the rice field. The pericarp is the raw material for extracting tannin extract. In the process of planting the camellia oleifera, the roots of the camellia oleifera trees are watered and fertilized, and the leaves of the camellia oleifera trees are watered and fertilized. Due to the characteristics of the camellia oleifera leaves, the camellia oleifera leaves face upwards, the surface is glossy, and water and fertilizer cannot be stored, so that the water and fertilizer can drip and run off easily when the water and fertilizer is sprayed on the front side, the water and fertilizer cannot be absorbed as much as possible, and therefore, the back side spraying work of the camellia oleifera leaves needs to be carried out. At the back liquid manure spraying in-process that carries out the tea-seed oil tree leaf, the liquid manure integrated device who adopts the blowout formula carries out the spraying, and the spraying effect is excellent, can guarantee the absorption effect of liquid manure. But among the current liquid manure integration spraying device, the hydrojet structrual installation is in the below of tea-seed oil tree leaf, though the steadiness is higher, but can not carry out the regulation of height, it is poor to use the flexibility, when mounting structure installs simultaneously, it is comparatively loaded down with trivial details, be unfavorable for the installation to dismantle, and whole device is when using, the pipeline of connection need bury underground in the soil, utilize soil to carry out the protection of pipeline, but the position of pipe connection is provided with the valve, the valve is buried underground equally in the soil, when needing the operation valve, need dig out soil, the process is comparatively loaded down with trivial details, soil still probably causes the valve to block to be unable to operate simultaneously, there is certain limitation in the use.
