Abstract

An anti-percolating and humidity-reserving film technique for planting trees in desert in order to modify the desert features that a layer of film is spread under the root of sampling for preventing water percolation. a water dropper is buried in surficial ground near the sampling for dropping irrigation, resulting in that a certain humidity and nutrients are reserved in the sand around the sampling root to ensure the survival condition of sampling. After the root system of the tree has grown deeply, it will grow by itself.

Description

Desert arboriculture films anti-penetration and moisture technology

There is vast desert area in China, also has a lot of desertifications of land every year.Desertification of land has destroyed the ecological balance, has caused harsh climate, is threatening the condition of human survival.Protection soil is avoided desertifying, and administering the desert is the important topic of keeping environment for human survival.In desert area and desert edge afforestation is a good measure of checking winds and fixing drifting sand, building the greenery patches, improving soil condition.Have long-range social benefit and economic benefit.

But in the desert, plant trees, a difficult problem that runs into is how to keep the required nutrient water of surviving of trees, and only guaranteed trees absorb needed moisture and nutrient from root, and trees just easily survive, at this problem, I have worked out a new method the films anti-penetration and moisture technology.

This new technology be at the root of sapling apart from about the root 20-40 centimetre of thick about 0.2MM of depths layer overlay, the film about wide 100CM, waterproof is permeated downwards, puts a weep pipe at it by on the trunk of root, in order to the timing drip irrigation, to guarantee the humidity and the nutrient of root.Concrete mode See Figure one to figure three.

Figure one, two shows that film is placed and sapling is planted drip irrigation schematic diagram, actual implementation procedure is as follows:

1, at first,, dig several gullies, spread film by certain line-spacing.

2, plant the sand that sapling (seeing figure three) (for guaranteeing to survive, sapling root should with going up a little original soils) covers the 40-50 cm thick by certain spacing again.

3, repave the pipeline that drips, establish a gargoyle every sapling stem portion, and then cover the sand of 10-20 cm thick, water the water of a 30-50 millimeter.

4, under the later normal condition, by tank at regular time and quantity by gargoyle to shoot root portion drip irrigation, because the waterproof downward infiltration of root bottom part film, the water dropping openings top has one deck sand to cover again can prevent water evaporates, so can keep a certain amount of moisture and the nutrient of sapling root, trees just easily survive, after trees survive, along with growth, its coring can pass film to the depths, and extend at other place, when waiting to grow to the root system of certain scale, can find the water source of depths, desert, keep the needs of self growing.

Here some technical conditions and the requirement that need to illustrate are:

1, the size here is an approximate number, different types of woods, and according to scientific and reasonable spacing, root is dark, and difference and requirement should be arranged.Here x represents that y represents spacing in the rows according to woods kind, the definite line-spacing of density.

2, film should be can be by the desert, and the soil dissolving absorbs.

3, tank should cause semi-enclosed sphere shown in the figure three, and because of spherical volume maximum, front face area is on average minimum; Sealing then is in order to reduce evaporation, but for fear of negative pressure, guarantees water outlet, leaves an aperture at the water inlet tops.Container outer surface plates the silvery reflection metal covering, and anti-sunshine tans by the sun heat absorption makes water temperature too high, the container bottom stretch out one with the liquid level volume display tube of lucite system to show the volume of water surface elevation and water in the container.

4, weep pipe is with thick arm flexible pipe, can prevent that compressive deformation blocks and gets rusty, and shallow embedding prevents to tan by the sun and bursting by freezing in sand.

5, the trees kind for well, to prevent the natural enemy infringement, strengthens himself resist ability with reasonably combined hybrid.

Claims

1. this anti-penetration and moisture technology, i.e. films anti-penetration drip irrigation technique.

2. desert according to claim 1 arboriculture films anti-penetration and moisture technology is characterized in that:

1. the size here is an approximate number, and different types of woods are dark according to scientific and reasonable spacing, root, and difference and requirement should be arranged.Here X represents that Y represents spacing in the rows according to woods kind, the definite line-spacing of density.

2. film should be can be absorbed by desert, soil dissolving.

3. tank causes semi-enclosed sphere shown in the figure three, and because of spherical volume maximum, front face area is on average minimum, and sealing then is in order to reduce evaporation, but for fear of forming negative pressure, guarantees water outlet, leaves an aperture at the water inlet tops.Container outer surface plates the silvery reflection metal covering, and anti-sunshine tans by the sun heat absorption makes water temperature too high, the container bottom stretch out one with the liquid level volume display tube of lucite system to show the volume of water surface elevation and water in the container.

4. weep pipe is with thick arm flexible pipe, can prevent that compressive deformation blocks and gets rusty, and shallow embedding prevents to tan by the sun and bursting by freezing in sand.

5. the trees kind for well, to prevent the natural enemy infringement, strengthens himself resist ability with reasonably combined hybrid.
