Abstract

The utility model relates to a mulch film and secondary film covering device. The mulching film and the secondary film are covered on the ridge of the farm field, the covered shallow ditch part is provided with a water storage disc, and the water storage disc is provided with water storage holes. The utility model is widely suitable for the mulching film and the secondary film coverage on snow jujubes, fruits, vegetables and other crops. In the mountain areas and the plain arid areas, the water is not evaporated, and the bumper harvest is ensured. In the areas with seasonable weather and good water conservancy conditions, the yield increase is ensured. As the mulching film and the secondary film are all covered, the diurnal amplitude is reduced, the light irradiation is increased, the yield increase, the leaf protection and the income increase are ensured, the water consumption is reduced, and the labor is saved. After covered, the weed is inhibited to grow, the weed has no need of being removed, the pesticide is less used as the general pest is hotly died, the procedure is decreased, and the labor is saved.

Description

Mulch film two film cladding systems

The utility model relates to a kind of mulch film two film cladding systems, mainly preserves soil moisture water conservation to guarantee the usefulness of good harvest for grand snow jujube, fruits and vegetables and various crops.

Prior art is that film half covers, and promptly a ridge to long crops covers film.Its weak point is: evaporated easily by moisture in the film covering shallow ridges soil, cause the not enough and arid underproduction of crops root system moisture content on the ridge; When rainwater is big, shallow ridges and near loam thereof are washed away and runs off; Shallow ridges director grass increases the operation of hoeing up weeds.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides that a kind of moisture is difficult for evaporation (i.e. soil moisture conservation), loam can not run off and the mulch film two film cladding systems of long weeds, water-saving and volume increase not.

The purpose of this utility model can reach by following measure: to farmland ridging all standing, there is the water storage dish at the shallow ridges position that two films cover to the utility model, and the water storage hole is arranged in the water storage dish with mulch film two films.

Accompanying drawing is a structure partial view of the present utility model.

The accompanying drawing piece number is represented:

1, ridge 2, shallow ridges 3, two films

4, dash parapet 5, water storage dish 6, water storage hole

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents structure of the present utility model, and the ridge in piece number 1 expression farmland is used for planting grand snow jujube, fruits and vegetables or other crops, and shallow ridges 2 is arranged between two ridges.What the utility model adopted is two films 3 thicker than agricultural film, certainly, also can adopt film.During bedding, the ridging all standing is carried out on ridge and shallow ridges.In the shallow ridges, be provided with at a certain distance between 4, two parapets of dash parapet and two ridges and surround rectangle water storage dish 5.The water storage hole of going deep in the soil 6 is arranged in the water storage dish.The width of water storage dish is by the distance between the ridges decision of crops, and it is fixed that the length of water storage dish is come according to local rainfall, landform (hillside fields, level land or terraced fields etc.) and crops kind.

The utility model contrast prior art has following advantage:

The mulch film that 1, can be widely used in grand snow jujube, fruits and vegetables and other crops covers Lid.

2, in mountain area and arid area, Plain: to rainwater or water, water flow into the water storage dish and and then goes in the soil by the water storage orifice flow because all standing, water can not evaporate, the crops root system has adequate water to supply with, and can guarantee good harvest.

3, favourable weather (for the crops) and the good area of water conservancy condition: can guarantee volume increase.Owing in the soil sufficient moisture content is arranged, when the water yield is big, above shallow ridges, unnecessary rainwater is discharged, and can not take away loam under the film, even the arid of meeting by chance, the interior moisture content of soil can not evaporate under the film, reaches the purpose that soil moisture conservation is respond well and minimizing is poured number of times and used manpower and material resources sparingly.Because all standing two films, can reduce day and night temperature, and all standing brings reflection and the refraction of daylight from soil towards film, comparable prior art increases illumination, improves 5 ℃-7 ℃ of temperature, to promote plant growth, guarantees to protect leaf, increases production and increases income.

4, can reduce water consumption and saving manpower.

5, can contain weed growth after the covering, need not hoe up weeds,, can go and buy Chinese medicine less, reduce operation and save the labour because general insect can be reduced the growth of bacterium property rot by hot dead.

Claims

1, a kind of mulch film two film cladding systems is characterized in that, there is the water storage dish at the shallow ridges position that two films cover, and the water storage hole is arranged in the water storage dish.
