Description

Water and fertilizer integrated irrigation system for litchi planting

Technical Field

The utility model relates to an agricultural planting irrigation equipment technical field especially relates to a litchi is planted and is used liquid manure integration irrigation system.

Background

China litchis are mainly distributed in the range of 18-29 degrees in northern latitude, the most are cultivated in Guangdong, the second time of Fujian and Guangxi, and a small amount of litchi is cultivated in Sichuan, Yunnan, Guizhou, Taiwan and other provinces.

Litchi is sweet in taste, sour and warm in nature, and enters heart, spleen and liver meridians; can stop hiccup and diarrhea, is a good food therapy product for intractable hiccup and morning diarrhea patients, and has the effects of nourishing brain, building body, stimulating appetite, benefiting spleen and promoting appetite; litchi wood is solid, elegant in texture and corrosion-resistant, and is a top-quality material all the time. Therefore, in the litchi planting place, litchi has become one of the important ways for farmers to increase income.

Aiming at litchi planting, reasonable irrigation of litchi trees in a drought season is an important item in litchi daily management in a litchi growth process, such as: because the roots of young litchi trees are underdeveloped and the roots of young litchi trees are shallow, the normal growth of young litchi trees is very sensitive to the moisture content of surface soil, and when the surface soil is in water shortage, the plants are easy to have wilting symptoms of leaf rolling and drooping, for example, if the water shortage time is long, old leaves are yellowed and fall off from bottom to top, the growth of the plants is seriously influenced, and even the plants die.

Aiming at the characteristic that litchi is usually planted on a hillside, an irrigation system suitable for litchi planting is designed, which is a technical problem to be solved urgently by technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned characteristics of proposing to litchi often select the hillside to plant, design the irrigation system that suitable litchi was planted, the technical problem that technical personnel in the field await solution urgently, the utility model provides a water and fertilizer integration irrigation system for litchi is planted. The irrigation system is suitable for water and fertilizer integrated irrigation in the litchi planting process.

To the above problem, the utility model provides a litchi is planted and is used liquid manure integration irrigation system solves the problem through following technical essential: the litchi planting water and fertilizer integrated irrigation system comprises water reservoirs, a pump connected with the water reservoirs through a water inlet pipe, a water outlet pipe connected to the outlet end of the pump, a fertilizer storage box connected to the water outlet pipe in series, and a plurality of drip irrigation heads connected to the water outlet pipe, wherein the number of the water reservoirs is two, the water inlet pipe at one end of each communicating pipe is located at the bottom of one water reservoir, the water inlet pipe at the other end of each communicating pipe is located at the bottom of the other water reservoir, and the two water inlet pipes of each communicating pipe are connected with a first cutoff valve;

the bottom of each reservoir is paved with a gravel layer.

In the prior art, aiming at the characteristics of common litchi planting in mountainous regions and slope bottoms, a reservoir is generally arranged near a planting area for solving the problem of irrigation water source, and is used for collecting and storing rainwater so as to provide irrigation water for litchi irrigation through a water body in the reservoir in arid seasons. Meanwhile, the irrigation system for fertilizing along with the water body generally has the characteristics of small water outlet and small water outlet flow of the irrigation system in a spraying and drip irrigation mode.
