Abstract

The utility model relates to a novel ecological paddy field with symbiotic association of loaches and paddy rice. A circular furrow is arranged between the paddy field and borders of the field and crisscross furrows are arranged in the field; the circular furrow and the crisscross furrows aggregately cover 10-12 percent of the total area of the field; nets preventing the field against land enemies and a net preventing the field against water birds are respectively mounted surrounding the field and on the top surface of the field by fixed brace bars; an inflow pipe and a drain pipe are positioned respectively on the borders at the two sides corresponding to the field; and an inlet of the inflow pipe and an outlet of the drain pipe are respectively located on the diagonal of the field. The utility model has the advantages of simple structure, low material demands, complete structure preventing the field against both land enemies and water birds, thereby ensuing stable water quality; the circular furrow and the crisscross furrows in the paddy field can facilitate productivity operation, thereby encouraging the growth of the loaches and leading to effective weeding and deinsectization for the whole field. The novel ecological paddy field is suitable for large-scale and standardized production and mainly solves various ecological problems in breeding loaches in paddy fields.

Description

Loach and paddy rice symbiosis novel ecological rice field

Technical field

The utility model relates to loach and paddy rice symbiosis novel ecological rice field.

Background technology

It is the ecological fishery mode that promotes increases in grain production, fishery synergy that loach is supported in the rice field.It is joint grain that loach is supported in the rice field, save land, economize on water, save fertilizer, save agricultural chemicals type ecological fishery.Loach is the favourable paddy growth of the movable chesson of latent brill in the rice field, and loach can play the effect of ruining careless deinsectization in the rice field, reduces weeds and strives fertilizer and rice pest; The ight soil of loach is again the fertilizer of paddy rice, has saved chemical fertilizer, through bacterial decomposition, has cultivated abundant plankton again, provides bait for loach again conversely.Obviously, the loach comprehensive utilization of can yet be regarded as is supported in the rice field, promotes a diversified economy, and reaches the road of the two benign cycles of increasing production of grain loach.

Show according to the study, loach is supported than simple species rice in the rice field, but every mu of additional income 2-3 doubly, and rice loach commensalism ecotope, and not only rice yield is stable, also owing to limit the use of and use less agricultural chemicals, the paddy of producing can reach green food standard, improves the quality of products, and has increased farmers' income, therefore, it is quite general that loach is supported in China rice field.

Because supporting loach, the rice field still has the equipment that complete anti-ground harmful animal and aerial aquatic bird are invaded harm, and standardization, scientific rice field structure, therefore, survival rate and output that loach is supported in the rice field still exist very big potentiality to wait performance.

Summary of the invention

In order to reach the purpose of scale, standardization loach and the loach high yield synergy of paddy rice symbiosis novel ecological rice field, it is a kind of simple in structure that the utility model provides, loach that is easy to build and paddy rice symbiosis novel ecological rice field.

The technical scheme that realizes above-mentioned purpose is as follows:

Loach and paddy rice symbiosis novel ecological rice field comprise the rice field; Be provided with circular groove between described rice field and the ridge, be provided with ditch in length and breadth in the rice field, and the width of circular groove is greater than the width of ditch in length and breadth; The circular groove area is the 10-12% of rice field area with ditch area sum in length and breadth;

The above fixedly strut of the uniform six roots of sensation of the ridge in described rice field periphery, rigid staybolt masthead portion is connecting anti-aquatic bird Kongzhong respectively; The above fixedly bottom of strut of the six roots of sensation is provided with anti-ground harmful animal invasion net, and anti-ground harmful animal invasion net is the rectangle round; The corresponding side ridge in rice field is provided with water inlet pipe, and the opposite side ridge is provided with drainpipe, and the branch drain that stretches in the rice field is being communicated with drainpipe; The water inlet of described water inlet pipe and the discharge outlet of branch drain lay respectively on the diagonal of rice field.

Described anti-aquatic bird Kongzhong comprises steel cable and collodion silk line, and the steel cable that is connected and fixed the strut top forms the rectangle round, and rectangle round steel cable is laid with the collodion silk line respectively between the corresponding both sides; Spacing between the adjacent collodion silk line is 30cm.

Anti-ground harmful animal invasion net height degree is 30-50cm.

Described branch drain is the telescoping tube of being made up of 2-3 water saving pipe.

The utility model is simple in structure, materials are saved, having complete anti-ground harmful animal and aerial aquatic bird invades the mechanism of harm, advances drainage mechanism, the field circular groove, the ditch area is moderate in length and breadth, and depth of water appropriateness is easy to stabilizing water quality and is convenient to the yielding ability operation, circular groove, longitudinal furrow or traverse furrow are convenient to loach and are entered each position activity of rice field on a large scale and look for food in the rice field, when promoting the loach growth, loach plays the effect of ruining careless deinsectization again in the rice field, reduces weeds and strives fertilizer and rice pest; Its culture efficiency obviously surpasses the effect that loach is supported in present rice field.The utility model is more suitable for producing use in scale, standardization, high quality, has mainly solved the rice field and has supported the problems such as many ecology that loach exists.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1, loach and paddy rice symbiosis novel ecological rice field comprise rice field 8, and the rice field specification is long 200000mm * wide 50000mm, and the ridge slope is than pressing ridge face width 2000mm 1: 2 or 1: 2.5.

Be provided with circular groove 9 between rice field 8 and the ridge 11, be provided with ditch 10 in length and breadth in the rice field 8, and the width of circular groove 9 is greater than the width of ditch 10 in length and breadth; And the circular groove area adds that the ditch area is the 10-12% of rice field area in length and breadth; The height on the ridge exceeds field face 500-800mm, peripheral circular groove furrow width 5000mm, and dark 500-800mm, the wide 100mm of longitudinal furrow or traverse furrow, dark 300-500mm, longitudinal furrow or traverse furrow are connected with circular groove; Bottom of trench tilts to discharge outlet, and from West to East, the discrepancy in elevation is 200-300mm.
