Description

Technical Field

[0001] The present invention relates to the field of plant cultivation technology, and in particular to a submerged plant seed ball. Background Art

[0002] As the main primary producers, submerged plants are an important part of the ecosystem structure of shallow rivers and lakes. They play an important role in releasing oxygen, purifying water quality, and stabilizing sediments in the process of water ecosystem restoration. At present, the restoration of submerged plants has become one of the hot spots for eutrophication control and landscape water ecological restoration.

[0003] In water ecological restoration projects, the survival of submerged plants is a key factor in the successful construction of an ecosystem. The premise of survival is that submerged plants can quickly take root in the water, grow quickly, and hold the soil, thereby promoting plant growth. Conventional submerged plants are planted by transplanting after drainage, but many rivers, lakes or reservoirs do not have drainage conditions and need to be thrown. Some use stones as counterweight materials to tie submerged plants and throw them. Often due to water erosion, submerged plants are difficult to take root and have a high mortality rate; some use cloth to wrap submerged plants with soil balls for throwing. Due to the long decomposition time of non-woven fabrics, submerged plants still have a prolonged rooting period at the bottom of the river and lake, and the survival rate is not high. Continuous replanting is still required in the later stage. Utility Model Content

[0004] In order to solve the above-mentioned problem, the present application provides a submerged plant seed ball, which includes a spherical shell, and the spherical shell includes an upper opening and a plurality of hollow holes passing through the spherical shell.

[0005] The submerged plant seeding ball proposed in this specification may bring beneficial effects including but not limited to: (1) The seeding ball can be integrally formed, and can be used as a container for submerged plant seeds and a weight material for seeds, which is conducive to the submerged plants sinking to the bottom of the water. The outer shell of the ball wall is formed by extrusion of a biodegradable material starch base, which is a material that can be degraded by microorganisms. The degradation of starch base is accelerated after contact with water, and finally decomposed into carbon dioxide, water and biomass. It is an environmentally friendly material and does not pollute the water environment. Moreover, the biomass produced during the decomposition process can be used as a carbon source for microorganisms to degrade pollutants, which is beneficial to the elimination of sediment pollution; (2) The hollow holes are evenly arranged in a triangular shape on the seed ball. After the seed ball is thrown, no matter which direction the ball is inclined, there are pores for the roots to take root in the underwater soil, which is beneficial for the roots of submerged plants to pass through the ball and take root and survive in the underwater soil; (3) After the seed ball is thrown, the root strengthening agent in the filler melts and is released when it comes into contact with water, which is beneficial to the rapid growth of the roots of submerged plants and the rapid rooting of plants; (4) The starch-based film wraps the submerged plant soil ball. The film has good water absorption and air permeability, which is beneficial to the preservation of submerged plants and prevents them from rotting due to long-term airtightness.
