Problems solved by technology

However, the use of layered relocation that is highly agitating to the soil will cause confusion between each layer of soil, and the original soil porosity will be destroyed, and it will be difficult to restore the original soil compactness when the soil layer is restored.

Embodiment 1

[0031] Example 1 The "Zhengzhou Key Field Scientific Observation and Experimental Station of the Movable Soil Ecological Environment of the Ministry of Agriculture" established in 1988 is one of the seven bases in the national "Soil Fertility Base Network" and the only one in the Huanghuaihai region. Locate the monitoring base. However, with the rapid expansion of the city, the test base has been located in a busy city. Due to the impact of the urban island environment, climate and human factors, it had to be relocated. The method steps are as follows:

[0032] (1) Excavation of foundation pits Excavated foundation pits suitable for the volume and shape of the soil to be relocated at the Henan Academy of Agricultural Sciences Modern Agricultural Science and Technology Experimental Demonstration Base in the suburbs of Zhengzhou City;

[0033] (2) Saw the soil Excavate a working surface of appropriate size (10m×15m) in the appropriate area of ​​the soil to be relocated, as a spa...

Embodiment 2

[0040] Embodiment 2 A soil original state relocation and restoration method is basically the same as in Embodiment 1, the difference being that in step (2), the depth of the soil sawing is 120 cm; in step (3), the straight square The soil column is cut into a cuboid shape (100cm×80cm×120cm); the vegetation restoration step is not included. The structural form of used fixed mold is identical with embodiment 1, and its volume size is adapted to the earthwork in this example.

Embodiment 3

[0041] Embodiment 3 A soil original state relocation and restoration method is basically the same as in Embodiment 1, the difference is that in step (2), the soil is sawed into an upright regular triangular soil column; in step (3), Cut the soil column into a regular triangular prism (120cm in length on the bottom side and 100cm in height). The enclosure body of fixed mold used is the triangular prism shape that matches with regular triangular prism, and cutting base plate is equilateral triangle, and all the other are substantially the same as the fixed mold in embodiment 1, and its volume size is adapted to the earthwork in this example.

Abstract

The invention relates to a method for undisturbed relocation and recovery of soil and a die for fixing undisturbed earthwork. The method comprises the following steps of: cutting the soil as a plurality of regular earthworks, fixing the earthworks by a fixed die on, hoisting and stably transporting the fixed die to the relocation destination, carrying out seamless assembly in a containing pit by a corresponding sequence, pouring the butt-jointed soil edges by the slurry and prompting the butt-jointed soil edges to be melted quickly. The die for fixing the undisturbed earthwork comprises an enclosure body, a cutting soleplate movably butt-jointed to the bottom end of the enclosure body and a fastening component leading the enclosure body to be fixedly connected with the soleplate; the upper end of the enclosure body is provided with a hoisting hook along the internal side. The method can effectively maintain the original state of the soil, has small disturbance to the soil structure, reserves the physical property and biological property of the relocated soil to maximum extent and continues the soil information. The relocation is not limited by time, the relocation can be carried out at any growth stage of crops, the whole progress of the test is not affected, the relocation efficiency is high and the cost is low.

Description

technical field [0001] The invention relates to a method for relocating and restoring soil in its original state and a fixed mold for the original earthwork. Background technique [0002] At present, many agricultural science and technology workers often encounter such troubles. It used to be an excellent area for setting up agricultural experimental sites. However, with the rapid advancement of urbanization (urban area expansion, road traffic occupation, human environment, etc.), environmental climate However, these excellent areas appear to be so "unsuitable" due to changes in the world. For general agricultural experiments, it is not difficult to "choose a good place to live in", but for those long-term, continuous For a revolutionary agricultural experiment, whether to relocate or not is a dilemma. For example, in the long-term soil fertility test, due to the difference in the amount of fertilization and the type of fertilization in each treatment area of ​​the test are...
