Abstract

The utility model discloses a mulching film which is used in the field of conservation of both moisture and soil for planting crops, trees and grass at drought areas with soil and water loss types. Namely, a plurality of water storage pockets are arranged on an ordinary mulching film. The water storage mulching film which is used can effectively store natural rainfall, conserve water and soil, mitigate drought conditions, prevent ecosphere worsening, cause the ecosphere to well develop, and improve crop yield and the survival rate of planted trees and grass.

Description

Mulch film

The utility model relates to and is used for " water and soil loss type arid " regional proportion of crop planting or planting trees and grass, the mulch film in the field that conserves water and soil.

Present known mulch film is the plastic film of individual layer, improves ground temperature in order to reach on the agricultural, prevents purposes such as soil moisture evaporation or containment weeds.Many places of China especially water and soil loss of the Northwest are very serious, and the damage caused by a drought drought frequently takes place, and soil is barren day by day.Cause the reason of this situation mainly to be: natural rainfall becomes rainwash to run off fast, and the availability on the spot of precipitation is very low; Because rainwash washes away soil, the higher table regolith of fertility washes away to be taken away, so the soil layer attenuation, soil holds the ability drop of staying moisture content, nutrient, and it is barren that soil just becomes.In order effectively to conserve water and soil, protection soil fertility is contained its degradating trend and is made it and reverses to benign development, uses common mulch film just can't obtain this effect.

The purpose of this utility model is to provide a kind of can holding effectively to stay precipitation, the mulch film to control soil erosion.

For achieving the above object, the technical solution adopted in the utility model is: mulch film is provided with the retaining pocket.

Retaining pocket recited above is by two-layer mulch film hot pressing or be bonded, promptly in the middle of overlapping two-layer mulch film, be provided with the separation rib, both sides are provided with the reinforcement rib, just form the retaining pocket between the separation rib and between separation rib and the reinforcement rib, the upside of separating rib in each of centre is provided with the arc rib near the sack position, between the arc rib and the arc rib with strengthen then forming the sack of intaking between the rib; Also promptly at the local two-layer mulch film that rib is arranged by hot pressing or be bonded together; On the two-layer mulch film below the arc rib, all be provided with spillway hole.

The utility model has the advantages that: owing to be provided with the retaining pocket on mulch film, just can hold effectively and stay precipitation, more when precipitation, when pocket held full water, follow-up precipitation can flow to ground by spillway hole voluntarily, and this overflow can not form washing away strongly of his-and-hers watches soil.Like this, both kept water and soil effectively, and held the water that stays and when local crop needs, to use again, thereby alleviated or eliminate damage caused by a drought.

Below in conjunction with the drawings and specific embodiments the utility model is explained in detail.

Fig. 1 is the structural representation of the utility model mulch film.

As shown in Figure 1, mulch film 1 is provided with retaining pocket 2.Retaining pocket 2 by two-layer mulch film 11 and 12 through hot pressing or be bonded, promptly in the middle of overlapping two-layer mulch film 11 and 12, be provided with and separate rib 13, both sides are provided with strengthens rib 16, just form retaining pocket 2 between the separation rib 13 and between separation rib 13 and the reinforcement rib 16, the upside of separating rib 13 in each of centre is provided with arc rib 15 near sack 21 positions, then forms the sack 21 of intaking between the reinforcement rib 16 between the arc rib 15 and arc rib 15 and both sides; Also promptly at the local two-layer mulch film 11 and 12 that is provided with

rib

13 and 15 and 16 by hot pressing or be bonded together, on the two-layer mulch film 11 and 12 below the arc rib 15, all be provided with spillway hole 14.

During use, mulch film 1 is laid immediately on the ground (notes making sack towards the upward slope direction) at slope land.Like this, rainwater or artificial spray water will flow to retaining pocket 2 and are stored along sack 21, when needs waters, need start or shake mulch film 1 slightly, and the water of storage will flow in the ground via spillway hole 14, and is very convenient.In the less area of precipitation, can stay rainwater or snow-broth to use so that hold with regard to laying plastic when winter slack for sowing in spring.On ridge ditch formula planting site, the retaining pocket on the mulch film can be hung over the both sides of ground ridge in 2 minutes, make sack 21 upwards, utilize the gradient on ridge ground to be more conducive to retaining.In " water and soil loss type arid " area, forestation planting grass all is difficult to survive, and uses this retaining mulch film can improve survival rate greatly, to quicken restore vegetation, conserves water and soil.
