Embodiment 1

[0021] Embodiment 1, a kind of Chinese tortoise annual breeding method for laying eggs may further comprise the steps:

[0022] (1) Choose healthy Chinese tortoises weighing only 700g. Among them, the ratio of female and male Chinese tortoises is 1:2. Except for the mating period, the female and male Chinese tortoises are kept separately. for 1 day;

[0023] (2) After 15 days of feeding the pre-matching feed, the mating of the Chinese tortoise is promoted. The pre-matching feed is obtained by adding a pre-matching feed additive in a proportion of 5% on the basis of the Chinese tortoise conventional feed. The pre-matching feed additive is Turnip extract, when making the turnip extract, mix turnip and water in a weight ratio of 1:4, extract with dichloromethane that is 1 times the weight of turnip, and the total extraction time is 80 minutes , reclaim dichloromethane, vacuum-dry the extract to obtain the extract of mandarin greens;

[0024] (3) After the Chinese tortoise is ma...
