Embodiment 1

[0035] Embodiment 1 Paddy field culture of the present invention becomes the method for crab

[0036] Please refer to the attached figure 1 , with figure 1 It is a schematic diagram of growing crabs in paddy fields according to the present invention.

[0037] The method for growing crabs in paddy fields of the present invention adopts rice, first-year-old crab species, soybeans ( Glycine max ) Trinity three-dimensional ecological planting model, including the following steps:

[0038] (1) Select paddy fields for cultivating adult crabs: the paddy fields for cultivating adult crabs 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 areas. Low-lying, shallow waters.

[0039] (2) Select the first-age crab species and carry out temporary breeding: catch the first-age crab species from the overwintering pond, an...

Embodiment 2

[0062] Please refer to the attached figure 1 , with figure 1 It is a schematic diagram of the rice field growing crab of the present invention.

[0063] (1) Selection of paddy fields: Crab-raising paddy fields should be selected in low-lying and shallow areas close to water sources, with good water quality, no pollution, convenient drainage and irrigation, strong water and fertilizer retention, not submerged during flood seasons, and large contiguous areas.

[0064] (2) Selection of rice seeds: Rice seeds should choose varieties that are resistant to pests and diseases, lodging, saline and alkali, fertility, high quality and high yield, and choose Yanfeng No. 47 rice variety.

[0065] (3) Selection of first-year-old crab species: first-year-old crab species are cultivated by themselves in the previous year. Catch the first-year-old crab species from the overwintering pond, and put them in the holding pond next to the paddy field for temporary cultivation. After moulting once...

Embodiment 3

[0087] During May-October, 2009, in Baqiang Town, Panshan County, Panjin City, Liaoning Province, a rice field crab cultivation demonstration area was implemented, and the method steps of Embodiment 1 were adopted to cultivate crabs in rice fields at the rice field cultivation crab demonstration base. Star No. 1 rice, and chose to stock crabs with neat specifications in mid-June, with an average of 12.5g / piece, 400 / mu. As a result, the average adult crabs caught in early October were 124g / piece, with an average of 30 kg / mu; the rice yield was average 767 kg / mu, as shown in Table 1.

[0088] Table 1 Comparison of yield and benefit between rice fields with crab and conventional rice fields (2009)

[0089]

[0090] As can be seen from Table 1: the input-output ratios of crab paddy fields and conventional paddy fields are respectively: 1:3.67 and 1:2.28; the average 124g / of crabs, an average of 30 kg / mu, and due to the paddy field culture adopted in the present embodiment The...

Abstract

The invention relates to a method for breeding adult crabs in rice fields. In the method, a rice, one-year crab species and soybean triune three-dimensional ecological planting and breeding model is adopted. The method has the following advantages that: the method is a new planting and breeding technology which improves the rice and crab symbiosis entironment and realizes pollution-free and eutrophicating rice and crab products by utilizing the mutual control and mutual promotion effects of the biological chains formed among such living beings as rice, pests, river crabs and the like according to organic combination of growth regularity of rice and the living beings; space, land resources and water resources are reasonably utilized and three-dimensional production of the rice fields is realized; and the regulation behavior of the natural ecosystem is simulated in the artificial ecosystem, diseases, pests and weeds in the rice fields are controlled by breeding crabs in the rice fields, ecological equilibrium is promoted and pesticide pollution is controlled, the rice yield can be increased, the agriculture cost can be lowered, increase of income of the farmers can be realized and the resource-conserving and environment-friendly ecological agriculture capable of realizing sustainable development is realized.

Description

technical field [0001] The invention relates to the field of aquatic ecological cultivation, in particular to a method for cultivating adult crabs in paddy fields. 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 have become the main means to ensure rice production. The environmental pollution caused, the output value is low, and the efficiency increase is slow. However, ponds, lakes and other cultured river crabs have been labeled as polluting water quality and destroying the ecological environment. It is imminent to develop new rice planting and river crab breeding technologies. [0003] In recent years, the northern regions of my country have begun to take advantage of the ecological resources of paddy fields to breed river crabs, develop ecological breeding technologies, and str...
