Embodiment Construction

[0019] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

[0020] Such as figure 1 , 2 As shown, the tree well formula water-saving irrigation method is carried out according to the following steps: the first step is to measure and check the soil condition of the forest land 1 that needs to be irrigated, and measure the average forest tree diameter and root system distribution area and soil of the forest tree 2. Texture, determine the size of the required shaft pipe with holes, in general, the more developed tree species of root system 4, the more sticky land of soil quality and the larger forest tree 2 of the tree ground diameter are selected the longer the shaft pipe with holes; Two steps: punch at least two holes 3 matched with the vertical shaft pipe with holes on the ground surface of the root system distribution area around every tree 2, the longer the vertical shaft pipe with holes, the deeper the hole...

Abstract

The invention relates to the technical field of a forest water-saving irrigation method, and relates to a forest well type water-saving irrigation method which is performed according to the following steps: (1) measuring and checking the soil condition of the woodland requiring irrigation and determining the size of required porous silo pipes; (2) forming at least two holes matched with the porous silo pipes on the ground surface of root distribution region at the periphery of each forest; and (3) installing the porous silo pipes in the holes formed in the step (2). According to the invention, the conventional forest surface irrigation method is changed, water is directly irrigated to the underground forest root distribution regions by a conventional trickle irrigation system and the lateral leakage of the porous silo pipes, the ground surface is kept in a drier or dry state, and the capillary pipes of the soil in the irrigation humid region and the soil on the ground surface are in a breaking state, so that the surface evaporation after irrigation is greatly prevented and reduced, the water is effectively supplied for the forest root system, and the water utilization efficiency is improved to achieve a water-saving purpose.

Description

technical field [0001] The invention relates to the technical field of water-saving irrigation methods for trees, and relates to a well-type water-saving irrigation method for trees. Background technique [0002] It is the country's development strategy to fully implement the forestry development strategy focusing on ecological construction and to better play the five functions of forestry ecology, economy, society, carbon sinks and culture. In the near future, my country will complete 6 million hectares of new forests every year. Afforestation implements the five major strategies of national land ecological security barrier strategy, national timber and grain and oil safety strategy, carbon sequestration and emission reduction strategy, greening and benefiting people strategy, and ecological and cultural prosperity strategy. Afforestation and afforestation of the motherland are national strategies and civic obligations and work areas, and more than 90 billion trees will be a...
