Abstract

Arid area trees water extraction from air drips irrigation device combines the method that promotes the trees keep -alive to the method of driping irrigation and plastic mulching method, makes the moisture of the inside evaporation of plastics canopy and the moisture of outside sleet frost collected root of tree again, reduces soil erosion and water loss, restraines weeds and grows, and the soil moisture conservation of ventilating improves ground temperature, reduces the highlight, reduce ground temperature round the clock with the seasonal change range, increase available state nutrient and organic matter content, improvement treelet survival rate is favorable to absorption and the growth of trees.

Description

Trees in Arid Areas air water-intaking drip irrigation appliance

Technical field

This enforcement case, for trees ' root feedwater, belongs to the required agricultural branch of portion of the human lives big class root that waters and feeds water group (A01G29/00).

Background technology

Arid area day and night temperature is big, and precipitation is few, and changes and precipitation rate is big, and Tendency analysis is uneven, air drying, and evaporation is big, has a strong impact on the development of forest.Owing to the trees of arid area do not possess canal irrigation condition, the method of drip irrigation is taked in many places, it is effectively improved the utilization rate of moisture, but drip irrigation is big in outlying arid area construction investment, need to beat deep-well, erection water fills, laying pipeline is many, to the berm tree of roadside or Radix Saposhnikoviae tree owing to route is far more not suitable for, and be more not suitable for owing to dropper freezes in ice period；Some place have employed covering with ground sheeting method, and mulch film has and prevents erosion, and improves ground temperature and reduces evaporation, reduce ground temperature round the clock with seasonal variations amplitude, the advantage being conducive to arboreal growth, but there is also easy long weeds, the problems such as noon temperature is too high, and breathability is bad, and root is perishable.

Summary of the invention

For the above deficiency existed, this enforcement case adopts the method that drip irrigation method and covering with ground sheeting method are combined, it is proposed that the method one air water-intaking drip irrigation appliance of Trees in Arid Areas keep-alive.

nullIts technical scheme is: a kind of Trees in Arid Areas air water-intaking drip irrigation appliance，Including black plastic cloth、Rubber ring、Iron wire、Water receiving pipe、Weeper、Water injection pipe，It is characterized in that black plastic cloth top is fixed on trees by rubber ring，Bottom is fixed in circular water receiving pipe by iron wire，Bottom grave is airtight，Water injection pipe top and water receiving pipe socket at a right angle，Embedment underground, bottom，The circular head and the tail of described water receiving pipe pass through adaptor cup jointing，3mm groove is opened in inside 45 degree of upside，Described iron wire diameter is more than water receiving pipe groove width，Described water receiving pipe and water injection pipe contact position open lower side，Water injects water injection pipe from weeper，Described water injection pipe arranges 4，Water hole is drilled through around lower end，Embedment underground, lower end 30-50CM，20-30CM is erectly gone up in upper end，Described black plastic cloth by tree centered by coning，Its lower edge has open end zipper airtight to rubber ring direction，Described black plastic cloth becomes U-shaped extraction for axle with iron wire in water receiving pipe fluting，Ground, whereabouts l-shaped outside water receiving pipe，With grave mound pile things on 3-5CM，Described black plastic cloth is close on the black plastic cloth of iron wire in U-shaped inner side after pile things on terminates and is opened a circle 1-2mm aperture along groove.

This enforcement case provides the benefit that: make the moisture of the internal evaporation of plastic greenhouse and the moisture of outside sleet frost be collected into again trees ' root, prevent erosion, suppress weed growth, ventilation soil moisture conservation, improves ground temperature, reduces high light, reduce ground temperature round the clock with seasonal variations amplitude, increase available nutrients and the content of organic matter, improve treelet survival rate, be conducive to absorption and the growth of trees.

Accompanying drawing illustrates:

Further illustrate below in conjunction with drawings and Examples.

Accompanying drawing 1: Trees in Arid Areas air water-intaking drip irrigation appliance profile；

Wherein: 1, black plastic cloth, 2, water receiving pipe, 3, iron wire, 4, rubber ring, 5, trees, 6, open end zipper, 7, air-vent, 8, weeper, 9, grave mound, 10, soil layer, 11, water injection pipe, 12, tree root.

Detailed description of the invention:

Arranging end circular diameter 1.5 meters, cone height 0.4 meter in legend, water injection pipe is height 0.25 meter on the ground.Wherein water receiving pipe is 6 points of plastic-aluminum pipe ranges 5 meters, and iron wire is No. 8 galvanized iron filament lengths 5 meters, and black plastic cloth is 1 2.5 square metres, and water injection pipe adopts 8 points of PE pipes.

1, early-stage preparations.In advance water receiving pipe is opened 3mm groove, is converted into circle and makes a call to 4 decile mouths.

2, loosen the soil and water.Selected trees, loosen the soil, water sufficient water.

3, dig water injection pipe and bury hole.Draw the circle of radius 0.75 meter with tree for diameter, opening four on circle is equidistantly the hole of 0.5 rice diameter 0.05 meter deeply.

4, dress black plastic cloth；Black plastic is planted along the upwards 0.35 meter upper folding of line, iron wire is pressed onto broken line place, by black plastic cloth around iron wire doubling, then insert along water receiving pipe one end notch together together with black plastic cloth, until other one end, water receiving pipe it is converted into together together with iron wire circle and makes notch upwards, walking around trees and water receiving pipe head and the tail are made adaptor cup jointing.

5, it is filled with water pipe.Loading water injection pipe at tapping, thread tapping is fixed into right angle, and 4 water injection pipes are inserted pre-buried hole.

6, pull-up open end zipper.Black plastic cloth open end zipper is pulled upwardly, mentions rubber ring sleeve on trees, open end zipper pretension.

7, water injection pipe and plastics are buried.Pre-buried hole compacting of vertically being nuzzled by water injection pipe is buried tightly, is converted into L-type along black plastic cloth along ground by lower, and with grave mound by L-type compacting, Polypropylence Sheet interface compacting is airtight.

8, fixing rubber ring.By rubber ring along trees to lifting up, make black plastic cloth coning strain, open end zipper is strained further.

9, air-vent is done.Bore with iron nail or ferrum inside water receiving pipe V-type interface on black plastic cloth, insert a collar aperture.

10, adjustment is checked further.Soil whether compacting is buried in inspection, and whether open end zipper is strained, and whether water injection pipe is vertical.

Experiments show that, this enforcement case is that Trees in Arid Areas growth provides lasting and stable water supply system, and it is to be directly inputted in soil by condensing drip, snow water, frost water or rainwater, by capillarity, the effect of the flow of water, water is slowly and evenly into plant root.Due to drip irrigation at underground 30-50CM to tree-feeding moisture, greatly reduce evaporation and the leaching loss of moisture, soil moisture content contrasts raising 13%, and improve is soil moisture 2-3 degree simultaneously, improves soil physical property, enhance nutrient content, improve the new slightly growth rhythm of trees, promote the spring slightly to grow, improve treelet survival rate, suppress the autumn slightly to grow, improve percentage of fertile fruit and yield.

When selecting economic tree, owing to moisture and nutrient are had higher requirement by it, then water receiving pipe circle overlay film diameter should be larger.The horizontal distribution of economic tree root system is relatively wide, general 1.5～2.0m；The root cap of water and soil conservation seeds is relatively larger is typically in 1.0～1.5, and the shrub species such as coniferous tree Root Distribution is relatively concentrated, and is typically in 1.0～1.2m, firewood forests are generally 0.8～1.0m.
