Embodiment 1
[0021] A biological agent for repelling birds in farmland, which is prepared from the following raw materials:
[0022] Rice straw, dolomite, sepiolite, sodium hydroxide aqueous solution, diatomaceous earth, benzyl acetate, ethyl acetate, methyl anthranilate, camphor oil, jasmine flower, thyme, cattail grass, fennel, water;
[0023] Specifically, it is prepared according to the following process:
[0024] 1) Pulverize rice straw, dolomite and sepiolite with a pulverizer, then add them to sodium hydroxide aqueous solution in turn, stir evenly, then let stand for 30 minutes, filter and air-dry, then mix with diatomaceous earth evenly, and grind until The particle size is 20 mesh, and the material A is obtained; the mass ratio of the rice straw, dolomite, sepiolite, sodium hydroxide aqueous solution and diatomite is 2:1:1:5:1; the sodium hydroxide The concentration of the aqueous solution is 0.5mol / L;
[0025] 2) Mix benzyl acetate, ethyl acetate, methyl anthranilate and campho...
Embodiment 2
[0030] A biological agent for repelling birds in farmland, which is prepared from the following raw materials:
[0031] Rice straw, dolomite, sepiolite, sodium hydroxide aqueous solution, diatomaceous earth, benzyl acetate, ethyl acetate, methyl anthranilate, camphor oil, jasmine flower, thyme, cattail grass, fennel, water;
[0032] Specifically, it is prepared according to the following process:
[0033] 1) Pulverize rice straw, dolomite and sepiolite with a pulverizer, then add them to sodium hydroxide aqueous solution in turn, stir evenly, then let stand for 30 minutes, filter and air-dry, then mix with diatomaceous earth evenly, and grind until The particle size is 50 mesh, and the material A is obtained; the mass ratio of the rice straw, dolomite, sepiolite, sodium hydroxide aqueous solution and diatomite is 2:1:1:5:1; the sodium hydroxide The concentration of the aqueous solution is 1mol / L;
[0034] 2) Mix benzyl acetate, ethyl acetate, methyl anthranilate and camphor ...
Embodiment 3
[0039] Bird repelling effect test of the biological preparation of the present invention:
[0040] Taking rice crops as an example, set up Example 1 group (dilute the biological agent of Example 1 by 1000 times, spray according to 10 kg per mu of land, and spray rice), Example 2 group (dilute the biological agent of Example 2 by 1000 times) times, according to 10 kg per mu of land spraying, spraying rice) and the blank control group (spraying according to 10 kg of water per mu of rice). The specific results are shown in Table 1:
[0041] Table 1
[0042] group Investigate the number of spikes Harmful number of spikes Hazard ear rate% Blank control group 5000 732 14.64 Example 1 group 5000 76 1.52 Example 2 group 5000 83 1.66
[0043] Conclusion: The biological agent of the present invention has good bird repelling effect, no damage to birds, environmental protection and no pollution, and can be applied to farmland to repel birds.
