Embodiment 1
[0022] A method applicable to crossbreeding of different geographical populations of escargot mainly comprises the following steps:
[0023] (1) Cage preparation: In early April 2018, the rice fields or ponds were first divided into isolated breeding areas, female snail breeding areas, male snail breeding areas, and paired hybrid areas. The above-mentioned areas were isolated from each other, and then 35-mesh plastic Nets or metal nets are used to make cages, and the cages are immersed in paddy fields or ponds. The open end of the cages is 5cm higher than the water surface, and then rice straw is placed on the bottom of the cages as a fixing matrix, and the distribution density is 1 cluster / ㎡. Then introduce 8 parts of benthic algae and 2 parts of small benthic animals to the fixed substrate by weight, and according to the amount of 5kg / mu to the paddy field or paddy field of the isolated breeding area, the female snail breeding area, the male snail breeding area and the matchi...
Embodiment 2
[0028] A method applicable to crossbreeding of different geographical populations of escargot mainly comprises the following steps:
[0029] (1) Cage preparation: In mid-April 2018, the rice fields or ponds were first divided into isolated breeding areas, female snail breeding areas, male snail breeding areas, and paired hybrid areas. The above-mentioned areas were isolated from each other, and then 40-mesh plastic was selected Nets or metal nets are used to make cages, and the cages are immersed in paddy fields or ponds. The open end of the cages is 6cm higher than the water surface, and then sugarcane top leaves are placed on the bottom of the cages as a fixing matrix, and the distribution density is 1 cluster / ㎡ , then introduce 8 parts of benthic algae and 2 parts of microbenthic animals to the fixed substrate by weight, and according to the amount of 5kg / mu to the paddy field of the isolated feeding area, the female snail feeding area, the male snail feeding area and the ma...
Embodiment 3
[0034] A method applicable to crossbreeding of different geographical populations of escargot mainly comprises the following steps:
[0035] (1) Cage preparation: In late April 2018, the rice fields or ponds were first divided into isolated breeding areas, female snail breeding areas, male snail breeding areas and paired hybrid areas. The above-mentioned areas were isolated from each other, and then 30-mesh plastic was selected. Nets or metal nets are used to make cages, and the cages are immersed in paddy fields or ponds. The open end of the cages is 4cm above the water surface, and then the mixture of rice straw and sugarcane tips and leaves is placed on the bottom of the cages as a fixed matrix. 1 cluster / ㎡, then introduce 8 parts of benthic algae and 2 parts of small benthic animals to the fixed substrate by weight, and spread them to the isolated breeding area, female snail breeding area, male snail breeding area and Biological fertilizer is applied to rice fields or pond...
