Unfreezing embedded rod for agricultural yield increase for seasonally frozen soil

Abstract

The invention discloses an unfreezing embedded rod for agricultural yield increase for seasonal frozen soil, and belongs to the technical field of agricultural production. The unfreezing embedded rodcan be buried in the non-frozen soil season in advance, the low temperature is sensed through a cold sensing sheet preset outside, the cold energy is transmitted to a cold pushing trigger ball; once the freezing temperature is reached, namely before the frozen soil environment is formed, the cold pushing trigger ball is frozen in advance and indirectly punctures a heating balloon to trigger the unfreezing action; after the heating balloon is punctured, a gas-solid heating body filled in the heating balloon is released; after the gas-solid heating body is exposed in the external environment, the gas-solid heating body starts to automatically heat to provide heat; meanwhile, the impact force of the gas-solid heating body is released to extrude part of nutrients out of the unfreezing embeddedrod to enter the soil; and in addition, heat released by reaction of the gas-solid heating body can also be transferred into the soil, the soil is heated, the frozen soil phenomenon is prevented, accordingly, seasonal frozen soil is heated and thawed, and the yield of crops is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural production, and more specifically relates to a thawing pre-embedded rod for increasing agricultural production for seasonally frozen soil. Background technique [0002] Seasonally frozen ground refers to various rocks and soils that have ice. Generally, it can be divided into short-term frozen soil (several hours / days to half a month) / seasonal frozen soil (half a 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. One of my country's main grain-producing areas, most of the northeast is seasonally frozen soil. The soil starts to freeze every winter and thaws in spring, and it doesn't fully thaw until July. The impact of seasonal frozen soil on agriculture includes the impact of thawing on the sowing season sooner or late...

Problems solved by technology

[0005] 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 not conducive 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
