Ecological blanket based on seed coating technology

Abstract

The invention firstly discloses an application of coated seeds to an ecological blanket to achieve a good effect on overcoming the defect that parts of seeds are not close to soil due to external water shortage, diseases and insect pests as well as suspended or uneven fields; components of coatings of the coated seeds are also targeted to be improved, due to the addition of plant fibers in a coating layer, the bonding strength among substances in the coating layer can be improved, and the coating layer can be effectively prevented from falling off; due to the introduction of aerogel to the coating layer, the coated seeds have high temperature resistance; in addition, the invention further provides an ecological blanket with an optimized structure, and the ecological blanket disclosed by the invention does not contain a nutrient substrate such as soil so as to be convenient to transport and mount and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of application of coated seeds in ecological blankets, in particular to an ecological blanket based on seed coating technology. Background technique [0002] With the rapid development of the economy, the construction of highways, railways and other traffic roads across the country, the excavation of mines and the development of real estate developers have damaged the ecological environment of the mountain, forming a large number of bare land, resulting in the destruction of the original surface vegetation, soil erosion, Various environmental problems, such as mudslides and landslides, have become a concern in the field of ecological restoration. [0003] Chinese patent No. CN201310193555.8 relates to a drought-resistant coating agent for controlling seed germination, coated seeds and its preparation method. The coating agent mainly consists of an inner layer coating agent (water retention layer) and an inte...

Problems solved by technology

The coating layer cannot play the role of heat insulation, and the seeds are prone to deterioration in a hot environment, resulting in a low seed germination rate

[0005] The existing ecological blankets generally wrap ordinary grass seeds, which cannot overcome the influence of external adverse factors such as external water shortage, disease and insect pests, ecological blankets hanging in the air, or uneven ground and some seeds not close to the soil when used in ecological blankets; The existing coated seeds processed by coating technology do not have the performance of high temperature resistance, and the coated seeds are placed in the ecological blanket, which will easily cause the seeds to deteriorate and reduce the germination rate in the case of hot weather; the existing coated seeds The coating layer of the seeds has low strength and does not have the ability to resist extrusion and impact. When used in the ecological blanket, the coating layer is easy to fall off and the seeds are easily damaged during the transportation and installation of the ecological blanket.
