Problems solved by technology

[0003] At present, in various water-saving irrigation water supply systems, single-pipe water supply is generally used. Although single-pipe water supply can meet the water needs of the irrigation system, it cannot be used in the construction of economic forests and ecological protection forests in the way of inter-row mixing. Satisfy the water supply according to the water demand characteristics of different tree species, which not only affects the water saving effect, but also restricts the allocation and use of plant species, which is not conducive to the development of forest biodiversity and the stability of the system

Embodiment

[0017] In the multi-branch pipe water supply and water-saving irrigation method of the present invention, the multi-branch pipe is connected to the bottom of the water outlet vertical pipe (2) by the main pipe (1) through the tee (6), and the top of the water outlet vertical pipe (2) is connected by the tee (6) Connect with the water distribution pipe (7), the two ends of the water distribution pipe (7) are connected with the branch pipe (3) through the central male threaded tee (4), connect the capillary pipe on the branch pipe (3), and connect the capillary pipe on the branch pipe (7) A ball valve (5) is fixed on it.

[0018] The water-saving irrigation method of multi-branch water supply is as follows:

[0019] a. First plant grouping: according to the depth of the root distribution of the plant species selected in the shelterbelt or ecological engineering construction design, the characteristics of ecological water requirements, and the differences in drought tolerance, th...

Abstract

The invention relates to a multi-branch water-supply water-saving irrigation method which separates the plants having same root distribution, ecologic water-need character and drought-enduring degree in a branch irrigation area into one group and uses a same branch to supply water to each group. In this way, different irrigation periods and irrigation quantities are set up differently according to the ecologic water-need character of different plants in one branch irrigation area. In the condition of building multi-tree mixing plants in lines in a protection forest which has bigger difference in water need among various trees, the method provided by the invention is utilized to supply water according to different water-need characters of plants in a branch irrigation area, in order to rich the plant species of protection forest, increase the biological diversity, promote water-saving efficiency, manage conveniently, decrease maintenance cost, widen the use range of plants, and save water.

Description

technical field [0001] The invention relates to a multi-branch pipe water-supply water-saving irrigation method, especially a water-saving drip irrigation method in arid areas, and is especially suitable for shelter forests, ecological forests, economic forests and water-saving agricultural projects in arid areas that adopt inter-row mixed configuration. Background technique [0002] More than 1 / 3 of the world's land area belongs to arid and semi-arid areas. In arid areas, precipitation is scarce, evaporation is strong, and water resources are scarce. Fresh water resources are the restrictive factors for industrial and agricultural development and ecological construction in arid and semi-arid areas. Water-saving irrigation technology in arid and semi-arid areas has been widely used in agricultural production, landscaping and ecological engineering construction. The technologies used in water-saving irrigation mainly include: sprinkler irrigation technology, drip irrigation t...
