Technical field

The utility model relates to field of forestry, particularly relates to a kind of tree planting tube of arid, semiarid zone tree planting use.

Background technology

The most of area of northern China belongs to the not enough 400mm of annual precipitation, steams and falls than greater than 3 arid, semiarid zone, because lack of water, survival rate of planting and storage rate are lower.In the practice of planting trees, some area covers a plastic film on the face of land around trunk, play the effect that reduces soil water evaporation speed and compile rainwater, methods such as admixing high hydroscopic resin in soil is also arranged, obtain certain effect, but since water or precipitation after soil moisture to side diffusion, root soil humidity descends very fast, under the unable again situation of watering of continuous drought, sapling survival rate and storage rate are affected.Application number is 01122261.1 " water-retaining and soil moisture preserving tree planting method for drought area ", and workload is big, cost is high, is used for the extensive difficulty of planting trees.

The utility model content:

The purpose of this utility model is exactly under watering the condition that can't water even of difficulty in arid, semiarid zone, provides a kind of rainwater and deep soil capillary water of making full use of to improve the plant trees tree planting articles for use easy to use, with low cost of tube of being called of sapling survival rate and storage rate.

The purpose of this utility model is achieved in that with moisture and can not sees through and the underground compliance with environmental protection requirements of burying, the harmless material of plant is made Fig. 1, shown in Figure 4 is last young, the trumpet type that end opening is big, on, the end opening shape can be circle, square and the rectangle that is suitable for sowing tree planting, ellipse etc., below all be called cone 1, open area is greater than last open area under it, the pass of cone 1 height H and its neck height h and sapling main root vertical height (see figure 3) is: H 〉=h＞ht (cylindrical shell h=H shown in Figure 4, Φ 4=Φ 2), can not break during barrel thickness can satisfy upright with it and banket in the centre light the rammer get final product, can economize on resources and reduces environmental pollution if join an amount of biodegradable master batch making cone 1 with the regenerated plastics masterbatch; (the outer shape can be square or circular at cone 1 a bonding shape that coincides with its center suitable for reading such as the plastic film 2 of Fig. 2, area is more than 10 times of open area on the cone 1), central openings (precipitation inlet and ventilation hole) shape is similar to cone 1 shape suitable for reading, area be on the cone 1 open area 1/25～1/2,4～8 cut offs that crack are no more than the border suitable for reading of cone 1 around the central openings, plastic film material should satisfy waterproof vapour and the difficult down aging condition of environment at sunshine, can reduce environmental pollution and follow-up work amount if make plastic film 2 with the light degradable material; Bonding cone 1 and plastic film 2 should use water-insoluble adhesive, and also available hot melt bonding method is bonding with both.Fig. 3 is the utility model and user mode schematic diagram (the close and size of dredging expression humidity of small circle in the soil) thereof.

Cardinal principle of the present utility model is: arid, the extremely low topsoil of the water content of semiarid zone is (as Fig. 3, below be called the G layer) (different regions about the about 10～40cm of thickness, different these thickness of weather conditions are different), the utility model tries hard to the sapling root is placed wetland all the time exactly, adopt cone 1 to block to water and precipitation after the sideways diffusion of moisture, and the end opening place upwards made capillary motion and moisture evaporated is accumulated to the less tree root place section (neck) of sectional area by expansion mouth, and the plastic film that place suitable for reading covers can guarantee that the most of moisture in the cone 1 can not be evaporated to outside, the face of land, also play simultaneously the effect that reduces the following other parts soil water evaporation of coverage rate and compile rainwater, because plastic film central authorities leave ventilation hole, can not influence the breathing of tree.Use this tree planting tube to meet light rain amount precipitation, it can be kept in the cone in the soil, unnecessary gravitational water can be entered in the soil of cone below, can not make tree root be in the ponding environment if meet heavy rain.The utility model with have only plastic film to cover or admix the high hydroscopic resin method and compare, can improve the availability of precipitation and deep soil moisture, increase the soil moisture of tree root environment of living in, when being 4 times as: end opening and area ratio suitable for reading, the moisture that place, tree root place unit passes through in the cross section from bottom to top can rise to nearly 4 times, and the area ratio is when being 9 times, and this value can be near 9 times.Because cone 1 neck is thinner, can impel most of sapling coring fast to the bottom growth, enter the many deep soils of water content as early as possible, after cone 1 was finished mission, sapling also can keep higher storage rate.

The utility model is equally applicable to desert area, and the G layer can be expressed as the dry surface sand bed.

The utlity model has following advantage:

1, after watering to sapling or compiling rainwater, most of moisture can remain in the semiclosed cone that does not influence the tree breathing and absorb for tree root (or seed) in the soil, improved the utilization ratio of water, especially can effectively utilize light rain amount precipitation, meet not ponding of heavy rain, help surviving and surviving of sapling;

2, because a variety of causes, under situation about can't water, the utility model is also upwards built up the moisture in the deep soil continuously except that compiling the rainwater, and the soil moisture that tree root (or seed) is located improves, and making the sapling survival rate improve becomes possibility;

3, the sapling coring comparatively fast enters deep soil, has both made to run into continuous high temperature, arid weather, and the storage rate of sapling is also higher;

4, if make cone 1, light degradation material making plastic film 2, can economize on resources, reduce environmental pollution and follow-up work amount with the biological degradation regenerated plastics;

5, simple in structure, easy to use, with low cost.
