Problems solved by technology

However, there are several deficiencies in this patented method: ① It is necessary to lay a layer of crushed straw in advance, and then turn it into the ground through subsoiling. Cultivation operations ② The straw will leave gaps when it is turned into the ground through deep loosening, which cannot completely isolate the salt, and the straw will begin to degrade in the soil for a month, affecting the isolation effect

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the patent of the present invention is further described. The present invention provides an in-situ film-forming and salt-separating operation device for saline-alkali land transformation in isolation of deep soil saline-alkali, such as figure 1 As shown, the frame (1) is composed of mutually connected and fixed square tubes and suspension devices, and is used to install and fix other devices, and is connected with the suspension system of the tractor to carry out traction and power input to the implement.

[0022] The high-pressure coating module includes a high-pressure pump (4), a high-pressure valve (5), a liquid film liquid tank (6), a multi-way pipe (7), a high-pressure infusion pipe (8), and a film-forming nozzle (9). The high-pressure pump (4) pumps the liquid membrane liquid out of the liquid membrane liquid tank (6), and flows into the multi-way pipe (7) after the pressure is adjusted by the high-pressure valve (...

Abstract

The invention provides an in-situ film-forming salt-isolation operation device and method for saline-alkaline land improvement. The device comprises a machine frame, an in-situ film-forming module anda high-pressure laminating module; the machine frame is used for supporting and fixing other modules, is in hooking connection or traction with a tractor suspension system, and provides power for other devices; the in-situ film-forming module is used for realizing deep scarification and layering operation on soil; and the high-pressure laminating module is used for spraying laminating liquid. Theoperation method in the invention is as follows: an in-situ film-forming scooper scoops up soil; liquid film liquid is sprayed through a film-forming spray head after scooping; after liquid is solidified, a layer of isolation film is formed; laminating areas are mutually overlapped through S-shaped advancing; a whole isolation film is formed; therefore, isolation of underground salt is realized;and salinization of soil is prevented.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to an in-situ film-forming salt-isolation operation device and method for saline-alkali land transformation, which realizes covering a layer of isolation film at a given depth in the soil, and prevents saline-alkali deep underground from penetrating into the surface layer and making cultivated land salty. Alkalizing. Background technique [0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with capillary water, and after the water evaporates, the salt accumulates in the surface soil. It refers to the phenomenon or process in which soluble salt accumulates on the soil surface, also known as salinization. China's saline-alkali soil has a wide distribution range, a large area, and many types, which seriously endangers the growth of crops and hinders the development of agricultural production.
