Arrangement composition of orchard pipe outflor irrigation system terminal

Abstract

The invention discloses an arrangement composition of orchard pipe outflor irrigation system terminal, which is characterized in that a capillary is buried underground; one end of the capillary connected with a main pipe through a branch pipe and the other end of the capillary extends out of the ground at 5-12cm at one side of the trunk of the fruit tree and extends vertically; the top end of the capillary is closed; the capillary is fixedly connected to the trunk of the fruit tree; shunting pipes in effective quantity are connected on the capillary along radical direction; the shunting pipes are fixedly connected with the branch of the fruit tree; the ends of the shunting pipes are provided with water outlets; and a flow straightener is installed between the shunting pipes and the capillary. According to the invention, the composition has little influence to orchard intertill, weeding, pesticide spraying and other farm work; mechanical work can be conveniently done; the problems of aging, deterioration and damaging are prevented; frost heave damage rate can be effectively reduced; replacing or cleaning can be easily done; the quantity and length of the shunting pipes can be set based on the size of the crown diameter freely; maintenance cost of terminal capillary, a flow straightener and shunting pipes are reduced, namely the position of the water outlet can extend outward at will along the branch of the fruit tree according to the requirement for suitable fruit tree irrigation.

Description

Technical field [0001] The invention relates to the technical field of water-saving irrigation facilities, in particular to a terminal structure of an orchard irrigation system. Background technique [0002] The small tube outflow irrigation system is a micro-irrigation system successfully researched and developed by the School of Water Conservancy and Civil Engineering of China Agricultural University. It is mainly aimed at the problem that the emitter is easily blocked during the use of the micro-irrigation system and the reality that the level of agricultural production management in my country is not high. mm) is small, but super-large flow channels are used, φ4PE plastic small tubes are used instead of drippers, and field seepage ditches and holes are supplemented to form a set of micro-irrigation systems that meet actual requirements with small tube outflow irrigation as the main body. [0003] The small tube outflow is an advanced underground root irrigation technolog...

AI Technical Summary

Problems solved by technology

[0019] (4) Since the water outlet of the small shunt pipe is set at 10-15 cm above the surface, and its outlet is located at 2 / 3 of the tree crown radius, in the modern orchard management that promotes grass growing and labor-saving cultivation and orchard mechanization, the existence of the small water outlet of the shunt pipe, Seriously affect orchard cultivating and weeding operations, and are particularly vulnerable to damage

[0020] 2. The disadvantages of connecting the capillary pipe on the ground to the flow stabilizer and then connecting the PE plastic shunt pipe

[0021] (1) Since the capillaries are directly distributed on the ground surface, usually one capillary is applied to each row or two rows of fruit trees, that is, the shunt pipes after the capillaries pass through the flow stabilizer are all distributed on the ground between the rows of fruit trees, which seriously affects the orchard cultivating, weeding, Spraying and other operations, especially vulnerable to damage

[0022] (2) Since most of the capillary pipes directly placed on the ground are PE plastic pipes, they are easily aged, deteriorated and damaged if they are exposed for a long time, and the probability of replacement increases, which increases the maintenance cost of the facility

[0023] (3) Fruit trees are basically planted along the contour line, but there is a certain gradient on the ground between the trees. Since the capillaries are directly distributed on the ground surface, the water stored in the capillaries at low positions is not easy to empty, and it is easy to swell when the low temperature freezes in winter in the north Broken capillary, increasing the maintenance cost of the facility
