Soil unfreezing embedded rod for seasonal planting yield increase

Abstract

The invention discloses a soil unfreezing embedded rod for seasonal planting yield increase, and belongs to the field of agriculture. According to the scheme, an embedded plate is inserted into soil,condensation generated by temperature difference enters a hollow rod through the upper end of a circular supporting plate, and a water-swelling ring in the hollow rod expands when meeting water; afteran expansion air bag is extruded by the water-swelling ring, the internal space of the expansion air bag is reduced, so that an LDPE film is punctured by a thimble in the expansion air bag, the watersolution in the expansion air bag and glycerol are mixed to react and release a large amount of heat, and thus the soil is heated; and when a warming device releases a large amount of heat, heat is transmitted into a mounting cylinder through a heat conduction rod, a shape memory spring in the mounting cylinder deforms when heated, an inner cylinder is ejected out of the mounting cylinder throughthe shape memory spring, remediation liquid is sprayed into soil through an atomization nozzle at the upper end of the inner cylinder, and therefore the soil temperature increasing range is enlargedin the soil remediation process.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a soil thawing pre-embedded stick for seasonal planting and production increase. Background technique [0002] Seasonally frozen soil refers to various rocks and soils with ice, which can generally be divided into short-term frozen soil (several hours / days to half a month) / seasonal frozen soil (half month to several months) and permafrost. [0003] Frozen soil is widely distributed in my country, accounting for 2 / 3 of the country's land area. Frozen soil can be divided into seasonal frozen soil and permanent frozen soil. [0004] One of the main grain producing areas in my country, most of the Northeast belongs to seasonal frozen soil. The soil starts to freeze every winter and thaws in spring, and it is not fully thawed until July. The impact of seasonal frozen soil on agriculture includes the impact of thawing on the planting season sooner or later. . [0005] The hydrological chara...

Problems solved by technology

[0006] Therefore, the seasonal frozen soil affects the vertical distribution of soil water content, making the migration of soil water obviously lag behind, which has a great impact on soil moisture, which is very unfavorable to the production of crops, which will not only lead to a decline in crop yield, but even cause frostbite of crops dead hard to grow
