Embodiment Construction

[0009] A method for breeding leeches in a paddy field is characterized in that: the paddy field is selected in a place with sufficient water source and convenient irrigation and drainage, the water inlet and outlet are provided with escape nets, and the paddy fields are also provided with anti-escape nets around, during breeding, 8000 leeches per mu of paddy fields are stocked. Young leeches and 20kg snails.

[0010] Based on the above, the water was replaced every 3 days during cultivation, and half of the water volume in the paddy field was replaced each time.

[0011] Based on the above, duck blood was fed once every 7 days, and the amount of each feeding accounted for 2% of the total weight of leeches in the paddy field.

[0012] Based on the above, when the paddy field is necessary to prevent and control diseases and insect pests, use less toxic and fully diluted pesticides. When spraying, spray on the leaves and do not spray in the net water body. After the pesticide is ...

Abstract

The invention discloses a method for breeding leeches in a rice field, wherein the rice field is chosen to be in a place where water is abundant and irrigation and drainage are convenient; escape-proof nets are arranged at an water inlet and drainage outlet, and on the periphery of the rice field; 8000-10000 young leeches and 20-30 kg of snails are put in each acre of rice field for breeding; through breeding leeches in the rice field and due to feeding habits of leeches, a great many injurious insects in the rice filed can be eliminated, so that the cost of pesticide can be effectively reduced, and the rice is more environmental-friendly, and besides, excreta of leeches and residual feed can serve as a good organic fertilizer, therefore, the usage of fertilizer in the breeding process can be reduced, and activity of leeches in the soil plays a role of loosening the soil, which brings great benefit to growth of rice. When the method for breeding leeches in the rice field is compared with the method of planting rice independently, the yield in increased by 5%-10%, the cost is reduced by 20%-30%.

Description

technical field [0001] The invention relates to the field of ecological breeding, in particular to a method for cultivating leeches in paddy fields. Background technique [0002] The existing technology mostly adopts the planting method that rice belongs to rice, and leech belongs to leech, and few combine the two to manage, which causes waste of resources and is not conducive to maximizing the interests of farmers. Contents of the invention [0003] The purpose of the invention is to provide a method for cultivating leeches in paddy fields, so as to realize the double harvest of rice and leeches and maximize the benefits of farmers. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: a method for cultivating leeches in a paddy field, characterized in that: the paddy field is selected in a place with sufficient water source and convenient drainage and irrigation; Anti-escape nets, when breeding, 8000-10000 young leech...
