Problems solved by technology

[0003] At present, most of the cultivation of Procambarus clarkii and loach adopts the "rice-shrimp" farming technology or "rice-loach" farming technology. The comprehensive utilization rate of the paddy field is not high, and the output of shrimp or loach is relatively low, and the ideal actual economic benefits have not been achieved.

Embodiment 1

[0030] The present embodiment provides a rice-shrimp-loach coupling culture method, specifically:

[0031] Since the rice-shrimp-loach coupling culture method of this embodiment can be cultivated in an annual cycle, therefore, on the basis of the cultivation in the previous year, the field was started on June 19 this year, and the rice seeding was carried out on the 20th by using a Rao type direct seeding machine. Mechanical Live. Among them, in the whole field process, the total area is 4hm 2 (1hm 2 =1 hectare=10000m 2 ) around the paddy field to form an annular ditch with a width of 5m, a depth of 1.8m, a slope ratio of 1:0.75, and a total area of ​​0.48hm 2 , accounting for 12% of the total area of ​​the paddy field, and the excavated soil is used to heighten and reinforce the ridge of the paddy field. On the side of the annular ditch close to the main road, cement box pipes with a diameter of 0.5m are pre-buried and stacked in a zigzag shape, so that the annular ditch ...

Abstract

The invention discloses a rice-shrimp-loach coupled cultivating method and a paddy comprehensive planting-cultivating mode, and mainly relates to the technical field of cultivation. According to the method, aquatic plants which are transplanted in a paddy in idle time are utilized as a bait source; the feeding amount of artificial feed is reduced; meanwhile, the cultivation time of procambarus clarkii and loaches (mainly the procambarus clarkii) is prolonged by utilizing the growth period characteristics of rice, particularly, late rice; the commercial specification and the cultivation yield of the procambarus clarkia are improved; aiming at the marketing specifications and the growth period characteristics of the procambarus clarkii and the loaches, the procambarus clarkii and the loaches are fished by adopting different modes; the loss of the commercial loaches is avoided; the comprehensive utilization rate of the paddy is improved. The method is an innovation of a paddy comprehensive planting-cultivating mode; the economic benefit of rice-fish coupled cultivation can be improved; the method has certain popularization and application values.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a rice-shrimp-loach coupled breeding method and a rice field comprehensive breeding model. Background technique [0002] Procambarus clarkii, also known as crayfish, has become a popular freshwater economic shrimp because of its fast growth, strong adaptability, and delicious meat. At present, Procambarus clarkii has become an important economic breeding species in my country; loach, a fish with high nutritional value, is called "ginseng in water", and now it has become a delicacy on people's tables. [0003] At present, most of the cultivation of Procambarus clarkii and loach adopts the "rice-shrimp" farming technology or "rice-loach" farming technology. The comprehensive utilization rate of the paddy field is not high, and the output of shrimp or loach is also relatively low, and the ideal actual economic benefits have not been obtained. Contents of the invention [0004]...
