Problems solved by technology

Under this mode, crayfish seedlings are mainly sold. However, the current paddy farming methods and models are not appropriate, and the crayfish produced are generally small in size, poor in color and have many diseases, which affects the output of crayfish. To ensure that the farmers get the corresponding economic benefits, and the price of crayfish fry varies greatly from March to May over time. Generally, the price drops rapidly in April and May over time. Therefore, it is urgent to Breed large size seedlings

Embodiment 1

[0029] A method for planting and cultivating rice and shrimp in continuous cropping, comprising the steps of:

[0030] (1) Selection and transformation of paddy fields

[0031] Select 60 mu of paddy fields with sufficient water sources, strong water retention capacity, convenient drainage, and no pollution sources around, and heighten and reinforce the ridges of the paddy fields so that the ridges are 70 cm higher than the paddy field level, and the ridges are 320 cm wide; The ditch is 1.4m deep and 5m wide), and the area of ​​the ring ditch accounts for 10% of the total area of ​​the paddy field, and the escape net is set up around the paddy field; after the rice harvest in the first year, the rice stubble is kept at a height of 30cm, and the rice straw that falls on the paddy stubble is kept. On the rice stubble, the rice straw is air-dried for 7 days;

[0032] (2) Aquatic planting

[0033] At the end of the rice straw drying period, start to plant Elodea in the paddy fiel...

Abstract

The invention relates to a breeding method for rice and lobsters through continuous cropping and belongs to the technical field of crop planting and aquaculture. The breeding method comprises the steps of rice field selection and transformation, rice planting and management, aquatic grass planting, breeding lobster putting, rice harvesting, breeding management, lobster fishing and the like. According to the method, the lobsters are cultured in the same rice field as the planted rice, chemical fertilizer and pesticide are not needed, time and space are fully utilized, a continuous cropping modeis combined with a co-cropping mode, the rice planted by means of the method is excellent in quality, the cultured young lobsters are large in size and high in yield, the marketing time is early, andthe economic benefit is greatly increased.

Description

technical field [0001] The invention relates to a rice and shrimp continuous cropping method and belongs to the technical field of crop planting and aquaculture. Background technique [0002] With the deterioration of the rice planting environment, the occurrence of diseases, insect damage and weed damage is becoming more and more serious. In traditional production, chemical fertilizers and pesticides are widely used, which not only brings hidden dangers to the consumption of rice, but also causes environmental pollution due to large amounts of fertilizers and pesticides. Rice-fishing comprehensive planting and breeding is based on the principles of ecological cycle agriculture and ecological economics, organically combining rice planting with aquaculture technology, agricultural machinery and agronomy, and constructing a rice-fishing symbiosis and mutual promotion system through engineering transformation of rice fields, and through Large-scale development, intensive manag...
