Embodiment 1

[0021] The cultivating method of raising crayfish in paddy fields of the present invention comprises the following steps:

[0022] (1) Paddy field preparation: First, paddy fields should choose early-maturing paddy fields with sufficient water sources, fresh water quality, no pollution, fertile soil, good water retention performance, convenient water inflow and drainage, quiet surrounding environment, and sufficient sunlight.

[0023] To transform the ridges, the height of the side ridges should reach 1.0m, the width should reach 80cm, the base of the ridges should be widened to 1.5m, the ridges should be compacted, and the slope ratio should be 1:3; Dig a 3m wide and 1m deep circular shrimp breeding ditch, and open a "well"-shaped field ditch in the middle of the field. There are inlet and outlet outlets, and the inlet and outlet outlets should be provided with escape barriers;

[0024] (2) Disinfection and fertilization of paddy fields: 10 days before the seedlings were rel...

Embodiment 2

[0035] The cultivating method of raising crayfish in paddy fields of the present invention comprises the following steps:

[0036] (1) Paddy field finishing: The ridges should be rebuilt, and the height of the side ridges should reach 0.8m, the width should reach 60cm, the base of the ridges should be widened to 1.2m, the ridges should be compacted, and the slope ratio should be 1:2; A 3m wide and 1m deep ring-shaped shrimp breeding ditch is excavated along the 1m inner edge of the field ridge, and a "ten"-shaped field ditch is dug in the middle of the field, with a width of 1.0m and a depth of 0.5m; plastic mesh is used to build escape prevention around the ridge The paddy field is provided with an inlet and outlet, and the location of the inlet and outlet should be selected on the soil ridge at the two opposite corners of the rice field, and the inlet and outlet should be provided with escape barriers;

[0037] (2) Disinfection and fertilization of paddy fields: 15 days befo...

Abstract

The invention discloses a method for intercropping a rice field with lobsters. The method comprises the steps as follows: preparation of the rice field, disinfection and fertilization of the rice field, planting of aquatic plants, snail throwing, seedling stocking, rice transplantation and daily management. The survival rate and yield of lobsters are greatly increased and the method has good economic benefit.

Description

technical field [0001] The invention belongs to the field of freshwater aquaculture, and in particular relates to a method for nesting crayfish in paddy fields. Background technique [0002] Crayfish, formerly known as Crayfish, is native to North America. It was introduced from the United States in Japan in the early 20th century, and was introduced into my country from Japan in the 1930s. The shrimp is widely distributed in rivers and lakes in my country, forming a natural population available for use. Especially in the middle and lower reaches of the Yangtze River, its population is relatively large, and it is the main production area of ​​crayfish in my country. The whole body of crayfish is a treasure, and its processed products are not only edible, but also widely used in the fields of medicine, environmental protection, food, health care, agriculture and scientific research, and have broad industrialization prospects. At present, the supply of wild crayfish is in sh...
