Benefits of technology

This patented technical solution involves developing a more efficient way to improve the efficiency of creation of rare earth metal alloys used in ornamental industries like railway fishery or greenhouse vegetables. Specifically, this approach includes introducing specific elements into existing sources of alloy materials called bismuth oxide, allowing them to be introduced without affecting their original properties. Overall, these techniques help reduce economic losses caused by poor quality crops while maintaining effective use thereof throughout China.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and effectiveness of natural fishery culture operations during certain regions where there may be large numbers of people living near these sites.

specific Embodiment approach 1

[0020] Specific implementation mode one: the method for improving Changbai Mountain Rana field ecological breeding output in this implementation mode is carried out through the following steps:

[0021] 1. Fertilized egg hatching method: a. Production and layout of the hatching basket: the hatching basket is woven with wooden strips and is cylindrical in shape. The height of the hatching basket is 40-50cm, and the diameter is 80-100cm; the hatching basket is placed on In the center of the hatching tank, the bottom of the hatching basket is raised by 10-15cm, and the outside of the hatching basket is fixed; the density of the hatching basket is set every 10-12m 2 Place 6 to 8 hatching baskets on the hatching water surface; b, put eggs: when the water temperature in the hatching pool reaches 5 to 6°C, put in frog eggs, put 5 to 7 frog egg groups in each hatching basket, and the total number of frog eggs is 6000-9000 grains; c. Control of hatching water quality: During the hatchi...

specific Embodiment approach 2

[0035] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the wood strips described in step 1 are Amorpha fragrans, Rhododendron or willow. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0036]Specific embodiment three: what this embodiment is different from specific embodiment one or two is that according to the spawning time of the forest frog when throwing in the frog eggs described in step one, the frog eggs produced within 2 days are hatched in the same pond to ensure that the forest frogs Frog embryos develop neatly. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a method for increasing yield of field ecologically bred wood frogs in the Changbai Mountain, and aims to solve the problem about low yield of the field ecologically bred wood frogs in the Changbai Mountain. The method includes: (1) hatching fertilized eggs; (2) breeding tadpoles; (3) breeding metamorphosized tadpoles; (4) cultivating one-year-old froglets; (5) overwintering frogs populations; and (6) catching commercial frogs. By the method, the average yield for test demonstrated unit area is 24.54 frogs/hm<2>, is increased by 77.83% as compared with the average yield which is 13.8 frogs/hm<2> of current farmers, and is increased by 29.16% as compared with the highest yield which is 19 frogs/hm<2>of the current farmers. The method is applied in the breeding field of the frogs in the Changbai Mountain.
