Soil conditioning device for saline-alkali land and construction method thereof

Abstract

The invention belongs to the technical field of soil repair application, and relates to saline-alkali lands, in particular to a soil conditioning device for a saline-alkali land and a construction method thereof. The soil conditioning device comprises partition pieces and a bottom plate matched with the partition pieces, wherein each partition piece comprises a middle plate and side plates arranged above the middle plate, the side plates are arranged close to the two sides of the middle plates, the side plates are obliquely arranged outwards, supporting plates are further arranged below the middle plates, the supporting plates are arranged close to the two sides of the middle plates, and the supporting plates are obliquely arranged outwards. According to the soil conditioning device for the saline-alkali land and the construction method thereof, use of borrowed soil is avoided, on-site utilization is achieved, inferior soil is changed into wealth, the land value of the saline-alkali soil is fundamentally improved, and recycling of the inferior saline-alkali soil and effective replacement of "borrowed soil" greening are achieved, damage of "borrowed soil" greening to the ecologicalenvironment of the soil source land is avoided, cultivated land resources are effectively protected, and balanced development of ecological environment construction is achieved.

Description

technical field

[0001] The invention belongs to the technical field of soil remediation application, and relates to saline-alkali land, in particular to a saline-alkali land soil conditioning device and a construction method thereof. Background technique

[0002] The salinization process is a process in which the salt contained in surface water, groundwater, and parent material gradually accumulates to the surface through the vertical and horizontal movement of soil capillary water under strong evaporation. The land where the salinity contained in the soil affects the normal growth of crops due to the salinization process is called saline-alkali land. For a long time, extensive and in-depth research has been carried out on the improvement and utilization of saline-alkali soil at home and abroad, and a lot of manpower and material resources have been invested. In the 1980s, foreign countries mostly focused on the application of chemical modifiers and deep plowing to destroy ...

Examples

Embodiment 1

[0027] Example 1, such as figure 1 , figure 2 As shown, this embodiment aims to provide a soil conditioning device for saline-alkali land that has little damage to the environment, low construction cost, and can effectively realize comprehensive restoration of saline-alkali land. Considering that the main reason for the formation of saline-alkali land is the salinization process, blocking the rise is the best means. Although the traditional formation of dark pipes can be blocked, the blocking area is limited. Therefore, in order to reduce costs and improve Blocking area, the saline-alkali soil conditioning device provided in this embodiment includes a partition 2 and a bottom plate 1 arranged in cooperation with the partition 2. In this embodiment, the partition 2 includes a middle plate 21 and a bottom plate arranged above the middle plate 21. Side plate 22, described side plate 22 is arranged near the both sides of middle plate 21, and side plate 22 is arranged obliquely o...

Embodiment 2

[0033] Embodiment 2 This embodiment provides a construction method using the above-mentioned soil conditioning device for saline-alkali land

[0034] First of all, lay the discarded crop straws on the surface of the saline-alkali land to be repaired. The thickness of the laying is 10 cm. The crop straws are preferably crushed straws. During the accumulation and fermentation process of straw, it is conducive to the growth of microorganisms, and the number of microorganisms in the soil can activate the nutrients in the soil to improve soil fertility.

[0035]The laid crop straws are deeply plowed, so that the crop straws are deeply plowed into the soil, so that the crop straws are the best organic matter for improving the soil. At the same time, through deep plowing, the salt on the surface can also be deeply plowed into the soil. Since the root system depth of most plants is only between 20cm and 30cm, for this reason, the formation of deep plowing and plowing of the soil is mo...
