Abstract

The invention relates to a method for controlling saline-alkali in tidal flats in watersheds, which belongs to a three-dimensional treatment method for removing alkali and eliminating salt by adopting buried pipes. The invention mainly solves the technical difficulties of shallow depth, easy silting and collapse, and poor salinity-alkali drainage effect existing in the existing methods for controlling river basin tidal flats. The technical solution adopted by the present invention is: a method for controlling the salinity of tidal flats in the watershed, which includes the following steps: a, first process a sieve hole on the hollow branch pipe; b, wind the outer surface of the hollow branch pipe with the sieve hole processed net bag; c. Buried the main pipeline in the tidal flats of the watershed, with a depth of 1.7-2.2m; d. In the tidal flats of the watershed, dug a channel for burying hollow branch pipes every 5-10m, then put the hollow branch pipes in and Fine sand is laid around the hollow branch pipe to wrap the hollow branch pipe, and one end of each hollow branch pipe is connected with the main pipeline; e, set up a vertical pipe and a gate valve with controllable water level on the main pipeline, so as to control the water level to be suitable for plant growth range.

Description

technical field [0001] The invention relates to a method for controlling saline-alkali in tidal flats in watersheds, which belongs to a three-dimensional treatment method for removing alkali and eliminating salt by adopting buried pipes. Background technique [0002] In a large number of tidal flats in river basins in my country, due to high alkalinity and high salinity, most of them become wastelands where crops cannot grow, and a small part of them are also intractable fields with low yields and difficult protection from drought and flood. In order to increase the arable land in our country, people have adopted the method of excavating drainage channels to eliminate salinity. Although this method can eliminate part of the saline-alkali, but due to the shallow depth of the drainage channel, it is easy to silt and collapse and the effect of saline-alkali drainage is poor. Contents of the invention [0003] The purpose of the present invention is to solve the technical dif...
