Abstract

The utility model relates to an anti-collapse wetting ditch for dry farming of a terrace. Ditch sides and a ditch bottom are formed by conducting excavation along the inner side of a ridge, water is contained in the ditch, the wetting ditch can be closed along the inner side of the ridge, and vertical and transverse ditch nets are communicated in terrace pieces to facilitate irrigation of dry land and fish farming. A water-pervious net is installed on the inner sides of the ditch sides and fixed in a piling mode to ensure that the wetting ditch is not deformed for a long term. The water-pervious net is a bamboo weaving net, a wood strip net or a plastic net. The ditch sides can also be formed by materials such as bricks and concrete in a support mode. Natural soil is kept at the ditch bottom, and the width and the depth of the wetting ditch are 50cm respectively. The wetting ditch solves the contradiction between terrace water storage and incapability in multiple cropping and is adopted for communication. The vertical and transverse ditch nets with certain density are adopted, the quantity of water in the terrace pieces is effectively maintained, sun crack of the ridge is avoided, dry land crops like vegetables can be conveniently planted in the dry land in a small piece mode, flood cropping alternates with dry cropping, and fish farming can be conducted between the ditch nets. When field restoring and seedling planting are required in spring, the ditch is flattened to discharge water, plowing and raking are conducted, the ridge cannot collapse, and paddy field seedling planting can be conducted.

Description

Ditch is soaked in the anti-avalanche of terraced fields dry farming

Technical field

The utility model is that ditch is soaked in the anti-avalanche of a kind of terraced fields dry farming.

Background technology

The farmland in the Pingba area plantation grain of both can having poured water, the Dry crops such as becoming nonirrigated farmland plantation vegetables that can discharge water again, the multiple crop index height, it is big that pattern of farming is adjusted the space, and unit soil output is big.Comparatively speaking, but there is the shortcoming that water, drought can't multiple cropping, the soil output capacity is low in the mountain area terraced fields.Because it is dried that in a single day the water in the terraced fields put, can cause the field piece dry and cracked because of lack of water, crack even can penetrate ridge very easily forms piping when pouring water, cause landslide, landslide again, causes the large tracts of land of terraced fields to damage, and influences farming.When this avalanche occurs in rice shoot plantation back, just pretty troublesome to the piece rescue property reparation of avalanche field, not only to spend a large amount of man-hours and material, the Honda piece under also therefore breaking-up has been planted is with the rice shoot of following field piece.

Therefore, how to find a kind of way to avoid terraced fields to ftracture because of drought, avalanche takes place when irrigating again become people to want to solve and the problem do not resolved always.

Summary of the invention

The purpose of this utility model is exactly at the problems referred to above, proposes the anti-avalanche of a kind of terraced fields dry farming and soaks into ditch, and to keep field piece soil property moisture, the assurance terrace cultivation is normally carried out, and is convenient to simultaneously breed fish.

Ditch is soaked in the anti-avalanche of this terraced fields dry farming that the utility model proposes, and it is characterized in that ditch group bottom of trench forms along the inboard excavation of ridge, maintains water in the ditch.

Soak into bank ridge inner closed.

When the field piece is big, in soaking into the zone that ditch surrounds, closure have ditch net in length and breadth to be communicated with, be convenient to water the nonirrigated farmland piece, breed fish and throw in the fish food.

For guarantee soaking into the ditch shape that remains unchanged for a long period of time, paste permeable net and piling in that ditch group is inboard.

Permeable net is bamboo weaving net, muntin grid or plastic wire.

As long-term use, materials such as available brick, concrete prop up builds ditch group, and bottom of trench keeps the nature soil property.

Soak into wide, each 50cm deeply of ditch.

Through the long-term observation experiment, find that the terraced fields cracking is because lack of water if keep soil to contain certain moisture, just can effectively be avoided the generation of this situation.In many mountain areas, China south, terraced fields can leave unused spring in the coming year after the rice harves, the peasant does not ftracture for keeping terraced fields, always hold the water in the piece of field full, to keep the soil property humidity, this mode can only be put limited fry in a suitable place to breed in autumn and winter season at most, because water temperature is lower, the fish poor growth, the fish crop of results is also very limited when transplanting seedlings to the coming year.On the other hand, because terraced fields are idle for a long time, the field can not multiple cropping, and utilization rate is lower, has restricted the growth of farmers' income.

Some time because arid is short of rain, do not hold how much water in the terraced fields, the water in the piece of field is easy to be dried, ridge dry and cracked test unavoidably, come again to rainwater, can cause the ridge avalanche again during retaining.

The utility model has solved terraced fields retainings and contradiction that can not multiple cropping, adopt the interior layback of infiltration bank ridge logical, the net of ditch in length and breadth of adding certain density links to each other, both effectively kept the water yield in the piece of field, avoid ridge dry and cracked, be convenient to the dry crops such as nonirrigated farmland fritter plantation vegetables between the ditch net again, accomplish the alternate crop rotation of floods and droughts, can breed fish between the ditch net, increase farmers' income.Need answer the field when transplanting seedlings to spring in the coming year, the backfill of ditch net is discharged water, turn over and rake, ridge can avalanche yet, achieves many things at one stroke.

The label of each several part is as follows among Fig. 1-3:

The last ridge of 1-; Slope, the 2-ridge; 3-ridge pin ditch; The little field of 4-piece; The 5-traverse furrow; The 6-longitudinal furrow; The ridge under the 7-; The 8-timber; The permeable net of 9-.

The specific embodiment

As Figure 1-3, Tong Yi Confucius terraced fields have the last ridge 1, the following ridge 7 and the side ridge to surround, and soak into ditch and comprise it being ridge pin ditch 3, traverse furrow 5 and longitudinal furrow 6.Become ridge pin ditch along ridge pin excavation.For wideer terraced fields, some traverse furrows and longitudinal furrow can also be excavated in Tong Yi Confucius field except leave closed ridge pin ditch along ridge pin, make it to form the ditch net, when keeping ridge not to be chapped from the cold because of lack of water, the drought of being convenient to little field piece 4 in the field is planted the crop pouring, and breeds fish.For narrower terraced fields, then only need excavation ridge pin ditch can soak into ridge and pouring.

For the last ridge in Tong Yi Confucius field, slope, the ridge 2 is steeper, causes the landslide sometimes at ridge pin trench digging, take place for avoiding this type of phenomenon, and the one, the last ditch group angle same with its maintenance that will soak into ditch, the 2nd, can beat timber 8 along ditch group and also protect with permeable net 9.Permeable net can be bamboo weaving net, muntin grid or plastic wire.As the bamboo that breaks, timber flaw-piece, wicker, even the net made of material such as broken asbestos shingle.

If run into the heavier time of damage caused by a drought, long-term dry farming possibly in the field, for keeping the infiltration of ridge, the shape that remains unchanged for a long period of time of soaking into ditch is very important.Materials such as available brick, concrete prop up and build ditch group at this moment, and bottom of trench keeps the nature soil property simultaneously.

Soak into the ditch size and be determined on a case-by-case basis, changeable, be as the criterion to guarantee that ridge is effectively soaked into.According to inventor's practice, soak into ditch wide, each 50cm is advisable deeply.

The infiltration ditch of ridge pin generally is closed, but not closedly also can play roughly the same effect.So not repelling the ridge pin of non-closure, the utility model do not soak into ditch.

The inventor is through for many years practice, find that this infiltration ditch not only can play the effect of the antiskid anti-avalanche in slope, can be used as " fish pass " and feeding district during rice field fish culture, can be as the pouring water during dry farming, and the farm manure storage facilities, also can be used to temporarily deposit fish.Ecological effect is satisfactory.

NM each several part label as mentioned above.
