Soil pre-buried seedling warm-keeping anti-freezing cover

Abstract

The invention discloses a soil pre-buried seedling warm-keeping anti-freezing cover, and belongs to the technical field of soil freezing prevention. The soil pre-buried seedling warm-keeping anti-freezing cover comprises an insertion sleeve ring and an oval protective cover fixedly arranged at the top end of the insertion sleeve ring; the bottom end of the insertion sleeve ring is fixedly connected with a plurality of uniformly-distributed heat storage plates, and two embedded rods are fixedly connected to the bottom end of each of the plurality of heat storage plates; and a through hole communicating with the interior of the oval protective cover is formed in the top end part of the oval protective cover, and a plurality of fan-shaped falling cavities corresponding to the heat storage plates in position are formed inside the periphery of the oval protective cover. The oval protective cover is arranged being matched with the plurality of heat storage plates which are arranged in soil in an embedded mode, and the oval protective cover is arranged on seedlings in a covering mode and plays a role in protecting and preserving heat of the seedlings; and the plurality of heat storage plates are filled with heating bodies, and the heating bodies conduct heat to the periphery of the soil at the roots of the seedlings through the heat storage plates after self-heating, so that the soilis heated, frost cracking of the soil due to strong low temperature is effectively prevented, and therefore the protection against the cold effect on the seedlings is achieved.

Description

technical field [0001] The invention relates to the technical field of soil antifreeze, in particular to a soil pre-embedded seedling warm and antifreeze cover. Background technique [0002] In the case of a colder environment, especially for some severe cold areas, the soil of the farmland will freeze and crack under low temperature, and the cold resistance of the crops is limited, especially the seedlings of the crops are often frozen to death in an environment with too low temperature, and the seedlings The survival rate is very low. In order to prevent soil freezing from affecting the growth of crops and the absorption of nutrients, it is often necessary to protect the soil from freezing. [0003] In the prior art, people often sprinkle hot water on the soil to thaw the soil. Although the soil thawing effect is fast, if the hot water is sprinkled on the seedlings improperly, the seedlings will be burned directly, and the treatment effect is not very good. . [0004] F...
