Embodiment 1

[0021] 1. Add tap water to the reaction kettle, add weighed starch under stirring, raise the temperature to 60°C, gelatinize for 1 hour, and cool to form a starch solution.

[0022] 2. Weigh the seeds of the flower stick, add them to the coating pan, and spray the starch solution while rotating. At the same time, other ingredients of the coating agent were slowly added. The coating agent consisted of 1% starch, 10% attapulgite, 7% peat, 3% superabsorbent resin, 1.0% potassium dihydrogen phosphate, 2% humic acid and 0.1% zinc sulfate. %, and the rest is fine sand, in percent by weight.

[0023] 3. After the weight of the seeds has increased by 3 times, add a small amount of pigment.

[0024] 4. Take out the large granulated seeds and dry them at 40°C or dry naturally.

Embodiment 2

[0026] 1. Add tap water into the reaction kettle, add the weighed starch under stirring, raise the temperature to 90°C, gelatinize for half an hour, and cool to form a starch solution.

[0027] 2. Weigh the seeds of Azalea japonicus, add them to the coating pan, and spray the starch solution while rotating. At the same time, other ingredients of the coating agent are slowly added, and the coating agent consists of 2% starch, 8% attapulgite, 10% straw, 5% superabsorbent resin, 1% humic acid and 0.1% zinc sulfate. The rest is fine sand.

[0028] 3. After the weight of the seeds increases by 4 times, add a small amount of pigment.

[0029] 4. Take out the large granulated seeds and dry them at 40°C or dry naturally.

Embodiment 3

[0031] 1. Add tap water into the reaction kettle, add the weighed starch under stirring, raise the temperature to 70°C, gelatinize for 1 hour, and cool to form a starch solution.

Abstract

The present invention discloses one kind of large grain coating agent for aerial seeding. The large grain coating agent consists of starch, attapulgite clay, plant cellulose, high hydroscopicity resin and fine sandy soil, and contains also fertilizer, plant hormone and trace elements. The present invention makes the aerial seed possess high germination rate and good late stage growth in condition of 10 mm rainfall. The large grain coated seed can be buried into sand under the action of wind, so that the present invention provides large area aerial seeding in harsh condition with technological support.

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...
