Problems solved by technology

It is true that high-stalk rice (reed rice) has good quality and tastes in line with the consumption habits of Chinese people, but because of its thick rice stalks, rice ears must be harvested manually. The mechanized harvesting technology of rice straw has not yet broken through, and manual harvesting is laborious and expensive. It is difficult to scale up and apply the model of planting tall stem rice in the short term

Embodiment 1

[0043] Step 1, Pond Construction:

[0044] 1) The number of the pond is 18#, the area is 6 mu, the depth of the pond is 0.8m, and the slope ratio is 1:2.5; a "back"-shaped trench with a depth of 0.5m and a width of 5m is excavated at a distance of 4m from the ridge of the pond. The inner side is used as a paddy field for planting rice; when excavating the "back"-shaped trench, a passage with a width of 3m is left for machinery to enter and exit the paddy field, and a rigid pipe with a diameter of 40cm and a length of 4.5m is installed at the bottom of the passage to facilitate trenching The water flow in the tank is universal; the pond cleaning and disinfection measures will be completed before the first ten days of December, and at the same time, 45cm high calcium-plastic boards will be set up around the ridge of the pond as crayfish and river crab escape prevention facilities;

[0045] 2) For the newly excavated "back" shaped groove, apply 250kg of fermented chicken manure p...

Abstract

The invention discloses a method for combining rice planting with shrimp-crab farming in an aquaculture pond. The method comprises the following step of pond construction, timely connection of fry stocking with rice planting and feeding management and field management. According to the method for combining rice planting with shrimp-crab farming in an aquaculture pond, a certain amount of shrimp-crab fry is reasonably stocked, the planting area of rice is reasonably planned, and in particular stocking of fry species of freshwater shrimps, crayfish and river crabs is effectively connected with rice planting in time so as to utilize the production capacity of the pond reasonably; besides, in the whole cultivation period, an appropriate amount of fish farming in the aquaculture water body of the pond is maintained, and under the premise of no use of aerobic facilities, high-quality aquatic products and high-quality rice which are capable of meeting the market demand, large in size and high in uniformity are provided in a stagger mode; moreover, diversification, economic and ecological benefits of the production of the pond are significantly increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for comprehensive breeding of rice, freshwater shrimp, crayfish and river crab in a breeding pond. Background technique [0002] Jiangsu, Zhejiang and Shanghai are the main breeding areas for river crabs and green shrimps in my country. The main breeding area for river crabs is about 5.5 million mu, and the main breeding area for freshwater shrimps is nearly 600,000 mu. In recent years, the market demand for bulk freshwater commercial fish and small-sized commercial crabs has been poor, and the prices have continued to slump, and the selling price has been inversely related to the cost of farming. However, the market demand for large-scale high-quality commercial crabs has been strong, hot-selling and high-priced. According to research in the main breeding areas, the culture of river crabs, freshwater shrimps and crayfish presents the following characteri...
