Embodiment 1

[0041] The implementation time is from May to October every year from 2015 to 2017. The implementation site is Baqiang Town, Panshan County, Panjin City, Liaoning Province. Crab-raising paddy fields are selected near water sources, with good water quality, no pollution, convenient drainage and irrigation, strong water and fertilizer retention capabilities, not submerged during flood seasons, and large contiguous low-lying and shoal areas. Field layout such as figure 1 Shown; Among them, including soybean planting area 1, rice side row planting area 2, small ridge 3, river crab 4, large ridge 5, ring ditch 6, field ridge 7, escape wall 8, water inlet 9 and water outlet 10. The width of the ridge 7 is 60-80cm.

[0042] It should be noted, figure 1 The river crab 4 shown in is a general designation to first-year-old crab species, crab larvae, and adult crabs and crabs after cultivation; and, figure 1 The position of the river crab 4 does not constitute a limitation to the bre...

Embodiment 2

[0069] The selected first-year-old crab species averages 10g / only; put 140 crabs per mu. The average amount of crab larvae selected is 0.005g / ; 45,000 are placed per mu. Others are the same as in Example 1.

[0070] In Example 2, the input-output ratio of the mixed-cultivation paddy field is respectively: 1:3.46.

Embodiment 3

[0072] The selected first-year-old crab species averages 10g / only; put 120 crabs per mu. The average amount of crab larvae selected is 0.005g / ; 45,000 are placed per mu. Others are the same as in Example 1.

[0073] In Example 3, the input-output ratio of the mixed-cultivation paddy field is respectively: 1:3.21.

Abstract

The invention relates to a method for mixed breeding of adult crabs and young carbs in a paddy field. A three-dimensional ecospecific breeding mode integrally combining rice, 1st crab species, young crabs, and soybeans is adopted. The method comprises the following steps: (1) selecting the paddy field; (2) selecting the 1st crab species and the young crabs, and respectively performing temporary culture; (3) fertilizing the paddy field; (4) digging an annular groove, a water inlet and a water outlet in the paddy field; (5) culturing rice crops and soybean crops; (6) respectively disinfecting the paddy field, the 1st crab specifies and the young crabs; (7) breeding the 1st crab specifies; and (8) breeding the young crabs. According to the method disclosed by the invention, weeds and insectsin the paddy field, and plankton and benthos in water are used for breeding the river crabs, and the quantity of the weeds, filamentous algae and pest in the paddy field can be controlled, so that themethod provides an ample space for growth of the rice crops and the yield of the rice crops is increased.

Description

technical field [0001] The invention relates to the field of ecological breeding of special aquatic products, in particular to a method for mixed breeding of adult crabs and crabs in paddy fields. Background technique [0002] In recent years, problems such as high dependence on chemical fertilizers and pesticides, increasing pests and weeds, declining soil production capacity, and environmental pollution have become important factors that limit the development of a single rice farming model, affecting rice yield and rice quality. However, the traditional river crab breeding mode has the problems of polluting water quality and destroying ecology. It is imminent to develop new rice planting and river crab breeding technologies. [0003] Raising crabs in paddy fields is a new type of ecological agriculture model combining rice planting and river crab farming, which has been practiced on a large scale in northern my country. Practice has proved that raising crabs in rice fiel...
