Device for increasing survival rate of seeds

Abstract

The invention discloses a device for increasing the survival rate of seeds. The device comprises a shell, a nutritional solution, a sponge and a gravity fixing plummet. A cavity is formed in the shell, a cylindrical tail wing is arranged on the upper portion of the shell, and air inlet holes are formed in the tail wing; the lower portion of the shell is cylindrical, and the lower end face of the shell is connected with a columnar connector; through holes are evenly formed in the side wall of the lower portion of the shell; the sponge is arranged in the lower portion of the cavity, and the nutritional solution is contained in the upper portion of the cavity; plant seeds are contained in the sponge; the connector of the shell is embedded in the gravity fixing plummet. The nutritional solution and the sponge are contained in the cavity in the shell, the shell is stably fixed to the desertified land through the gravity fixing plummet, the nutritional solution slowly permeates into the sponge, the plant seeds in the sponge develop under cultivation of the nutritional solution, and the seeds pass the through holes and the ground and grow into plants after germination. The device is used for desertification control, the control range is wide, investment is low, and the control effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of desertification control, and relates to a control device, in particular to a device for improving the survival rate of seeds. Background technique [0002] Desertification is the degradation of land in arid, semi-arid and sub-humid areas with drought hazards due to factors such as climate change and irrational human economic activities. On June 17, 1996, the second World Day to Combat Desertification and Drought, The Secretariat of the United Nations Convention to Combat Desertification issued a communiqué stating that the phenomenon of desertification in the world is still intensifying. More than 1.2 billion people in the world are directly threatened by desertification, and 135 million of them are in danger of losing their land in the short term. Desertification is no longer a It is a simple ecological environment problem, and it has evolved into an economic and social problem. It has brought poverty an...
