Embodiment 1

[0029] The method for polyculture of rice loach, 2 mu of field ridges as a unit, comprises the following steps:

[0030] A. Before the paddy field is plowed, a ring ditch with a depth of 150 cm and a width of 100 cm is dug at a distance of 150 cm from the inner side of the field ridge, and a passage with a width of 250 cm and a length of 250 cm is left in the middle of the ring ditch. The ring ditch and the passage form a " String" font;

[0031] B. The height of the first ring ditch outside the ring ditch is 50cm, the bottom width is 50cm, and the top width is 40cm. The first ring ditch field ridge, the second ring ditch field ridge and the ring ditch are covered with Lide film;

[0032] Open an opening with a bottom width of 50 cm and a length of 50 cm every 20 meters in the first ring ditch, and open at the corresponding position of the second ring ditch and the first ring ditch, and cover the bottom of the opening with the Lide film;

[0033] C. Install barbed wire or ny...

Embodiment 2

[0049] The method for polyculture of rice loach, 10 mu of field ridges as a unit, comprises the following steps:

[0050]A. Before the paddy field is plowed, a ring ditch with a depth of 150 cm and a width of 100 cm is dug at a distance of 150 cm from the inner side of the field ridge, and a passage with a width of 250 cm and a length of 250 cm is left in the middle of the ring ditch. The ring ditch and the passage form a " String" font;

[0051] B. The height of the first ring ditch outside the ring ditch is 50cm, the bottom width is 50cm, and the top width is 40cm. The first ring ditch field ridge, the second ring ditch field ridge and the ring ditch are covered with Lide film;

[0052] Open an opening with a bottom width of 50cm and a length of 50cm every 20-30 meters in the first ring ditch, and open at the corresponding position of the second ring ditch and the first ring ditch, and cover the bottom of the opening with the Lide film;

[0053] C. Install barbed wire or n...

Embodiment 3

[0069] The method for polyculture of rice loach, 8 mu of field ridges as a unit, comprises the following steps:

[0070] A. Before the paddy field is plowed, a ring ditch with a depth of 150 cm and a width of 100 cm is dug at a distance of 150 cm from the inner side of the field ridge, and a passage with a width of 250 cm and a length of 250 cm is left in the middle of the ring ditch. The ring ditch and the passage form a " String" font;

[0071] B. The height of the first ring ditch outside the ring ditch is 50cm, the bottom width is 50cm, and the top width is 40cm. The first ring ditch field ridge, the second ring ditch field ridge and the ring ditch are covered with Lide film;

[0072] Open an opening with a bottom width of 50cm and a length of 50cm every 25 meters in the first ring ditch, and open at the corresponding position of the second ring ditch and the first ring ditch, and cover the bottom of the opening with the Lide film;

[0073] C. Install barbed wire or nylo...

Abstract

The invention relates to the technical field of cultivation and discloses a rice and loach polyculture method. Two to ten mu of ridges serve as one unit. The rice and loach polyculture method includes the following steps of building the ridges, laying a sky net and a ground net, applying organic fertilizer, planting rice, stocking loaches and throwing feed. The rice and loach polyculture method is environmentally friendly and easy to operate, produced rice does not contain pesticide residues and thus the rice and loach polyculture method has application prospects. The loaches raised with the method can loosen soil in the rice filed, and thus manpower resources are saved. Because the sky net and the ground net are arranged, ospreys, egrets, night herons, snakes, mousse and other natural enemies are prevented from damaging the rice and the loaches.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for polyculture of rice and loach. Background technique [0002] Traditional agricultural production not only has low production efficiency and low income for farmers, but also relies on a large amount of pesticides and chemical fertilizers, causing a series of problems such as pesticide residues in rice fields, environmental pollution, rice quality decline, and increased resistance to pests and diseases. The vulnerability of agricultural land poses a serious threat to the sustainable development of agriculture and the rural economy. Although there is a method of mixing fish and rice in the existing ecological polyculture methods, the fish fry have relatively harsh requirements on the breeding conditions, especially when the rice is harvested, it still needs continuous water supply, which is a serious waste of water resources and fish prices. The rise is limited, an...
