Large grain coating agent for aerial seeding

Abstract

The invention discloses a large-granularized seed coating agent for aerial sowing. The coating agent is mainly composed of starch, attapulgite, plant cellulose, superabsorbent resin and fine sand. The coating agent also contains fertilizers, plant hormones and trace elements. The invention has the advantages of effectively solving the contradictions between the coating and damage of the aerial sowing seeds and the coating and germination. Under the condition of 10mm rainfall, the seed germination rate is high and the later growth effect is good. After aerial sowing, the seeds can be buried in the sand under the action of wind erosion, which solves the problem of seeds drifting with the wind on the windward slope of sand dunes, and provides technical support for large-scale aerial sowing under difficult site conditions.

Description

technical field

[0001] The invention relates to the field of ecological restoration and management. Specifically, the present invention relates to a large-grained seed coating agent for aerial sowing control in desert areas. Background technique

[0002] The western region is vast and rich in resources, not only has many animal and plant resources with medicinal value, but also has rich mineral resources and oil and gas resources. However, the west has the dual characteristics of rich resources and fragile environment, and the severe reality of desertification makes the demand for ecological construction more urgent for resource development and economic development. Due to long-term human activities such as over-logging, over-reclamation, over-grazing, and over-harvesting, sandstorms occur frequently. According to reports, it occurred an average of 5 times in the 1950s, and an average of 23 times in the 1990s. In recent years, although the state has increased investment i...
