Description

Technical Field

[0001] The invention relates to the technical field of desert control, in particular to an intelligent soybean urease-induced desert curing vehicle and a use method thereof. Background Art

[0002] Urease is used to hydrolyze urea to generate carbonate ions, which combine with calcium ions in sand or other substances to form calcium carbonate, thereby forming a hardened layer on the surface of the sand, which is equivalent to a protective shell. With the existence of the protective shell, on the one hand, the sand on the surface of the desert will no longer be blown away by the wind, and on the other hand, it can also improve the water holding capacity of the sand to a certain extent, promote vegetation growth, and achieve long-term and effective sand control effects.

[0003] Soybean urease is widely used because of its high yield, low price, high urease content and good economic efficiency. The soybean urease induced solidification liquid is divided into two liquids: soybean urease catalytic liquid and urea-calcium chloride mixed liquid. The two liquids are mixed before use. The preparation method of soybean urease catalytic liquid is to crush soybeans to less than 100 mesh, put them in tap water at a ratio of 20g / L, place them in a low temperature environment of 0-10℃ and let them stand for 24 hours, then centrifuge and take the supernatant, which is the soybean urease catalytic liquid. The urea-calcium chloride mixed liquid is made by mixing 1mol / L urea and calcium chloride evenly.

[0004] However, the thickness of the protective shell on the surface of the sand is also important. It should not be too thick or too thin. Too thin may lead to loose sand fixation, while too thick may affect the germination and growth of plants. This requires that the concentration and speed of spraying hydrolyzed urea match each other. However, the spraying amount cannot be well controlled at this stage. This leads to different thickness of the crust on the surface of the sand, affecting the effect of sand control.
