Example 1
By adopting the automatic low-temperature ampullaria gigas egg removal device to remove the egg blocks of the ampullaria gigas in the paddy field, the method comprises the following steps:
(1) Egg laying site for nutritional and beneficial ampullaria gigas
The ampullaria gigas can mate for many times and spawn for many times each year, and the annual spawning capacity of the ampullaria gigas is about 5000-9000. The egg laying period of the ampullaria gigas is 4-11 months each year, and the proper temperature for egg hatching is 22-32 ℃. The device is fixed at the spawning position of the rice Tian Zhongfu ampullaria gigas in the spawning period, so that the ampullaria gigas spawns can intensively spawn on the spawning rod 6.
(2) Automatic timing spraying liquid nitrogen
The ampullaria gigas usually spawns in the morning of 4-6 hours, and the spawning is completed before the sun is lightened, and by utilizing the characteristic, an automatic nitrogen spraying timer 5 is arranged, and liquid nitrogen is sprayed at the morning of 4-6 hours every day for 30 minutes. The nitrogen flows out through the nitrogen spraying pipe 7 and is sprayed through the rotary spray head 8. Sometimes, the ampullaria gigas can lay eggs in the daytime, and the ampullaria gigas are sprayed regularly in the time of day according to the specific local situation. The temperature is used as a restriction factor for influencing biological growth, and the liquid nitrogen is used for spraying the egg masses of the ampullaria gigas, so that the ampullaria gigas is eliminated from the source, and the agricultural economic loss caused by that the ampullaria gigas gnaws young rice seedlings, tender leaves and the like is reduced to the greatest extent. The killed ampullaria gigas eggs and the ampullaria gigas fall into the paddy field, can be used as soil nutrients, and realizes the ecological idea of harm conversion into benefit.
In addition, the appearance of the device can also be set to simulate birds or waterfowl animal modeling, and the paddy field pest is frightened by utilizing visual information transmission to realize paddy field protection, so that agricultural economic loss is reduced to a certain extent.
Example 2
By adopting the automatic low-temperature ampullaria gigas egg removing device to remove ampullaria gigas egg blocks in a water body environment, the steps are as follows:
(1) Egg laying site for nutritional and beneficial ampullaria gigas
Although the ampullaria gigas invades aquatic organisms, eggs produced by the ampullaria gigas cannot be hatched in water, the ampullaria gigas are mostly laid on inner walls of shoreside, lake, river and the like which are higher than water surfaces and stems of aquatic plants, and by utilizing the characteristic, the device is installed around water environments of the shoreside, lake, river and the like in the spawning period, so that the ampullaria gigas can intensively spawn on spawning rods 6.
(2) Automatic timing spraying liquid nitrogen
By utilizing the spawning characteristics of the ampullaria gigas, an automatic nitrogen spraying timer 5 is arranged, nitrogen flows out through a nitrogen spraying pipe 7 in a specific time, and liquid nitrogen is sprayed on egg masses of the ampullaria gigas through a rotary spray head 8. And adjusting the angle of the rotary spray head 8 for spraying the ampullaria gigas egg blocks on the inner walls of the bank, the lake, the river and the like.
(3) Egg mass collection treatment
After spraying, fine-pore wire meshes are fixed on the water surface near the inner walls of the lakes, rivers and ditches before spraying so as to prevent the ampullaria gigas egg masses from losing into the water body after spraying, and the egg masses which fall after death are collected and uniformly treated.
In addition, the appearance of the device can be set to simulate birds or aquatic animals, so that the device can better blend into the water environment while preventing and controlling the ampullaria gigas, the abrupt feeling is reduced, and the near-natural landscape effect is improved.
While the invention has been described with reference to preferred embodiments, it is not intended to be limiting. Those skilled in the art will appreciate that various modifications and adaptations can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the invention is defined by the appended claims.
