Embodiment 1

[0022] according to figure 1 Shown shrimp rice continuous cropping breeding technology, one of its schemes:

[0023] 1. Conditions for continuous cropping of shrimp and rice

[0024] Choose paddy fields with good water quality, sufficient water volume, no pollution sources, and convenient drainage and irrigation for shrimp farming. The paddy field covers an area of ​​five hectares. In the ridge of the paddy field, a circular feeding ditch with a width of 2 meters and a depth of 1.5 meters is excavated along the four sides, and a "ten" ditch is excavated in the middle. The ditch is 1 meter wide and 0.5 meters deep. The circular feeding ditch and the field ditch account for about 8% of the paddy field area. . Use the soil excavated from the excavation of the circular breeding ditch to reinforce, widen and heighten the field ridges. It is required to store 50cm deep water, the field ridges are 3 meters wide, and anti-escape facilities are installed at the water inlet and outle...

Abstract

The invention relates to a crayfish rice continuous-cropping breeding and planting technology. The invention has the special technical key points that: the rice field, which has good water quality, sufficient water and no pollution source and is convenient to irrigate and drain, is selected to breed crayfish; the area of the rice field is properly over dozens of acres; feeding ditches are excavated in ridges; a crayfish rice continuous-cropping breeding and planting mode comprises three modes of throwing seed crayfish, throwing ovigerous crayfish and throwing young crayfish; according to the requirements of the three modes, the seed crayfish or the young crayfish are thrown sufficiently in one step; when a large number of young crayfish move, artificial feed such as minced fillet, scrambled screw clam meat and the like are fed properly; in winter, crayfish enter caves to live through the winter; in March of the next year, the crayfish come out again after water temperature rises again, wherein the water temperature is controlled by a method for adjusting water depth and is controlled to be 20 to 30 DEG C commonly; and the crayfish are caught at the end of March to at the end of May every year. By the technology, the rice field can be utilized completely to artificially cultivate the crayfish; the problem that the rice field leaves unused in rainy seasons of winter and spring is solved; and a wide prospect for farmers to achieve prosperity is achieved.

Description

technical field [0001] The invention relates to the field of freshwater aquaculture, in particular to the technique of continuous cropping of shrimp and rice. 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 shor...
