Problems solved by technology

Long-term application practices have shown that drip irrigation is also one of the most reliable irrigation methods for brackish water irrigation. In addition to obvious water-saving advantages, the soil under the sprinkler (near the root zone) has a relatively low salt content, which provides great benefits for crop growth. It is beneficial to the environment and greatly alleviates the problems of crop root burning and soil secondary salinization caused by salt water irrigation. It is expected to become the most suitable irrigation method for Haloxylon planting. Agronomic integration measures and methods of controlling emitter clogging are still unclear

Embodiment Construction

[0045] Specific embodiments of the present invention are provided below, and it should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the technical solutions of the present application all fall within the scope of protection of the present invention. The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] In the embodiment of the present invention, 300 hectares of Haloxylon planted in Inner Mongolia Ulan Bu and Bayin Aobao Gacha Keboer Natural Village are examples. The 300 hectares of Haloxylon drip irrigation system is divided into 20 irrigation districts, wherein each irrigation district has Set up a drip irrigation system;

[0047] The drip irrigation farming system is composed of the first reuse device and the field drip irrigation device connected together, wherein the first reuse device consists of a mixed wate...

Abstract

The invention relates to a drip-irrigation system for Haloxylon ammodendron in a desert marginal area, and a planting method and an application for the Haloxylon ammodendron, belonging to the technical field of drip irrigation. The drip-irrigation system comprises a first reuse device and a field drip-irrigation device, wherein the first reuse device is connected with the field drip-irrigation device through a water delivery pipeline; through the first reuse device, an underground water source in the desert marginal area is distilled, and brackish water and fresh water obtained from distillation and separation are mixed into brackish-fresh mixed water in proportion; and the brackish-fresh mixed water is delivered to the field drip-irrigation device through the water delivery pipeline. Thedrip-irrigation system provided by the invention comprehensively considers salt tolerance of the Haloxylon ammodendron, clogging of an irrigation emitter and secondary salinization of soil under the condition of drip irrigation with brackish water, provides the control range of the salinity of irrigation water in different growth stages of the Haloxylon ammodendron, and solves the problems of over-high energy consumption and cost and low degree of automation for a conventional brackish-water desalination technology on the basis that the problems of root wilting of the Haloxylon ammodendron, clogging of the irrigation emitter and secondary salinization of the soil due to irrigation with high-salinity brackish water are solved.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a Haloxylon drip irrigation system in a desert marginal area, a Haloxylon planting method and its application. Background technique [0002] Haloxylon tree, also known as salt wood, has the characteristics of drought resistance, heat resistance, cold resistance, and salt and alkali resistance. It plays an incomparable role in wind and sand fixation, curbing land desertification, and improving soil. One of the main tree species selected for the project. However, water resources are extremely scarce in the border areas of the desert, especially in the sandy areas of Alxa and Xinjiang where the rainfall is below 150mm. At present, most of the cultivation methods of Haloxylon are under the condition of no irrigation. Although Haloxylon is resistant to drought, it is not suitable for In the desert fringe area with almost no rainfall, the seeds often fail to set fruit or matur...
