Description

Technical Field

[0001] The utility model relates to the technical field of planting, in particular to a planting device for improving the survival rate of saline-alkali land. Background Art

[0002] In the field of modern agriculture, the development and utilization of saline-alkali land has always been a major problem that has plagued agricultural production. Saline-alkali land, due to the excessive salt and alkaline substances in its soil, severely restricts the normal growth and development of plants, resulting in low crop yields and even difficulty in survival. Although traditional improvement methods, such as physical salt washing, chemical neutralization and bioremediation, have achieved certain results, they are often costly, long cycles, and have potential impacts on the environment, making them difficult to promote and implement on a large scale. Especially for seedling transplanting, because their roots are relatively delicate, they are directly transitioned from ideal growth environments such as greenhouses or nutrient pots to saline-alkali land. They are very likely to suffer physiological stress due to sudden changes in soil salinity, causing root damage and water absorption disorders, which ultimately affects the survival rate and restricts the effective utilization of saline-alkali land.

[0003] In the prior art, although there have been some attempts to improve saline-alkali land, such as using an isolation layer of special materials to reduce the upward migration of salt, or local soil replacement methods, most of these methods are not very targeted and it is difficult to take into account the continuity of seedling growth and the long-term improvement of the soil environment. Therefore, the development of an innovative planting device that can gradually enhance the salt-alkali tolerance of seedlings while ensuring a smooth transition in the early stages has become an important research direction for improving the utilization efficiency of saline-alkali land and the survival rate of crop planting. The design of this device requires comprehensive consideration of knowledge from multiple fields such as materials science, soil science, and plant physiology, aiming to create a microenvironment that both protects and trains seedlings, promotes the development of their root systems and the adaptive adjustment of their physiological functions, and opens up new paths for the sustainable development of saline-alkali land agriculture.

[0004] In view of this, it is particularly urgent and important to develop a planting device that can not only effectively alleviate the adverse effects of saline-alkali land on the initial growth of seedlings, but also promote their gradual adaptation and improve their survival rate in the saline-alkali environment.

[0005] Therefore, how to provide a planting device for improving the survival rate in saline-alkali land is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
