Sponge seedling raising bed

Abstract

Seed germination requires extremely strict conditions such as moisture, oxygen and the like, and at present, most of soil-less substrates for raising seedlings cannot meet the requirements on the moisture, stability of the substrates and other elements for raising the seedlings. In order to realize moisture preservation, ventilation and the like in the process of raising the seedlings without using soil, the invention provides a sponge seedling raising bed device which has the advantages of low cost, convenience for transplanting and the like. The sponge seedling raising bed consists of a plurality of blocky sponge seedling raising units which are connected with one another, wherein a groove is formed in the center of each sponge seedling unit block; a cross-shaped gap which is communicated with the bottom of each sponge block is formed at the bottom of each groove; each sponge seedling raising unit block is connected with other surrounding sponge unit blocks through a connecting part of which the width is about 1 mm; a hemispheric groove of which the diameter is about 10 mm is formed in the center of the top of each sponge seedling raising unit block; and seeds are placed in the hemispheric grooves. Each cross-shaped gap which has the same width as each groove is formed at the bottom of each groove and is communicated with the bottom of each sponge block, and each sponge seedling raising block has a cubic structure of which the side length is 20 mm.

Description

technical field [0001] The invention relates to a soilless seedling raising device, in particular to a sponge seedling raising bed. Background technique [0002] Seed germination is very demanding on conditions such as moisture, temperature, oxygen, and light, among which the requirements on water (partition) (oxygen) are the most stringent. The various nutrients in the stored seeds must be hydrolyzed under the action of water and further synthesize various enzymes for the germination of the seeds. Therefore, water is a necessary condition for the germination of all seeds. On the other hand, if there is a lack of good aeration conditions, too much moisture will hinder the absorption of oxygen by the seeds, inhibit the respiration in the seeds, and cause the seeds to rot. Seed germination generally has three requirements for the selection of soilless seedling substrate: (1) have a certain water holding capacity, that is, be able to absorb water for continuous use of seeds; (...

AI Technical Summary

Problems solved by technology

At present, there are many types of substrates used for soilless seedling cultivation, such as sand, gravel, vermiculite, rock wool, porous ceramsite, rice bran, peat, charcoal residue, sawdust, etc., but few of them can satisfy the above seedling cultivation conditions at the same time.
