Abstract
The invention provides a method for recovering vegetation in a desertified land in an extremely droughty area. The method relates to a movable temporary irrigation system which is used to supplement water to the desertified soil to promote the germination and growth of seeds in a soil seed bank; soil drought is used to induce plants with deep roots to grow downwards; and underwater or other water resources are used to achieve self-maintenance growth of the plants without irrigation. The method is different from a traditional high-investment forestation and vegetation recovery method, has the advantages of low investment and good effect, and is applicable to areas having certain water resources in the extremely droughty area.
Description
Technical field
The present invention relates to a kind of ecological construction method, be specifically related to a kind of Extreme Dry/drought-hit area desertification land method for recovering vegetation.
Background technology
Desertization refers in arid, semiarid (comprising that part half is moistening) area, owing to the destruction that the impact of natural cause and mankind's activity causes the ecosystem, making former non-desert area wind-sand activity occur is the degeneration of the similar sandy desertification environment of principal character.The land area that is subject to desertization impact on the earth has more than 3,800 ten thousand square kilometres, and at present, the whole world has 6,000,000 hectares of soil generation desertizations every year approximately.The scope that Desertification relates to is wide, has caused whole world concern.Desertization causes land deterioration, and productivity descends, and the earth's surface wind erosion is desertified, and sand dune movement is pressed and buried farmland, road, room, and also has influence on vast zone outside the desertification regions by Sand-dust Activities.
The most significant feature of Desertification is that vegetation cover degree reduces, and the important measures that prevent and treat desertization also are to recover surface vegetation.Traditional method of forestation needs great lot of water resources, nursery stock, perfect irrigation system, cost of investment is high, and at the Desertification especially Desertification of Extreme Dry/drought-hit area, shortage of water resources, social-economic base is poor, traditional afforestation is recovered vegetation technique and is difficult to promote, research be suitable for these areas cheaply technology for recovering vegetation be present technological difficulties.
Extreme Dry/drought-hit area desert area spontaneous growth plant species is in preferably period and some areas formation of natural moisture condition, although can form a large amount of seeds their every year, but arid drift sand earth's surface is difficult to germination and growth, the population breeding adopts the nutrition organs clonal propagation, so surface vegetation is once destroying extremely difficult the recovery.
The present invention is directed to the technical barrier of above existence, plan is passed through limited irrigation, excite plant seed in the soil seed bank, soil seed pool, especially dark root system plant (such as colored bavin, camel thorn etc.) seed, recover natural vegetation, form a kind of Extreme Dry/drought-hit area desertification land deserta low cost, quick recovery method.
Summary of the invention
The object of the invention is, provide a kind of Extreme Dry/drought-hit area desertification land vegetation low-cost quick recovery method, the method adopts removable interim drip irrigation system, utilizes this system to keep the skin wet to desertization soil, short-term is irrigated desertification land, excite the soil seed bank, soil seed pool germination and growth, form the seedling of primary natural plants kind, utilize simultaneously drought stress, impel seedling root to grow downwards, seek moisture, or finally utilize groundwater resources, realize independent growth.The method is applicable to bury of groundwater more shallow (being generally less than 10m), a certain amount of seasonal precipitation is arranged, the zone of a certain amount of flood is arranged.The method only needs temporary irrigation, can better recover natural vegetation, and oneself keeps growth to realize it, can realize the Desertification quick recovering vegetation, can be widely used in the ecological construction engineering.
A kind of Extreme Dry/of the present invention drought-hit area desertification land method for recovering vegetation, relate to the Mobile irrigation pipe network in the method, this irrigation pipe network is comprised of main (2), arm connector (4), arm valve (5), installation main valve (3), arm (6) and hollow billet (7), and concrete operations follow these steps to carry out:
A, set up irrigation water seedbed (1), install and irrigate power, lay the Mobile irrigation pipe network, end at main (2) is installed main valve (3), and at the impartial installation arm connector (4) of arranging of main (2) difference, valve (5) is installed on the arm connector (4), arm (6) is connected with arm connector (4);
B, drip irrigation pipe (7) is connected capillary pipe spacing 2m-5m, dripper spacing 1m-3m with arm (6);
C, open valve and begin irrigated soil, irrigated 5-8 hour continuously for the first time;
D, irrigate complete after, close the valve (5) on main valve (3) and the arm connector (4), unload lower branch line (6), moving to adjacent arm connector (4) connects, open valve (5) on main valve (3) and the arm connector, proceed to irrigate, mobile arm (6) is complete to irrigating in order;
After e, nursery stock sprout, carry out the second time and irrigate, irrigation time 3-5 hour, according to circumstances irrigate for the third time irrigation time 3-5 hour;
F, behind nursery stock Zhang Zhuanshi, stop to irrigate, stimulate by arid and induce root system to extend to underground water to get final product.
Only connect a pair of arm (6) on the step a main (2), be connected by upper each the arm connector (4) of mobile arm (6) and main (2), realize the irrigation to different sections.
A kind of Extreme Dry/of the present invention drought-hit area desertification land method for recovering vegetation, the method has overcome the difficult problem of the natural germination and growth of plant seed in the soil seed bank, soil seed pool of Extreme Dry/drought-hit area, promoted ecological recovery, have the following advantages: (1) utilizes the water resource of lacking than conventional method just can recover natural vegetation, makes the recovery vegetation can utilize underground water or flood oneself growth; (2) excavate Extreme Dry/drought-hit area soil seed bank, soil seed pool resource, need not conventional to grow seedlings, field planting, the long-term irrigation; (3) removable irrigation pipe network availability is high, small investment.
A kind of Extreme Dry/of the present invention drought-hit area desertification land method for recovering vegetation, if the reserves of the soil seed bank, soil seed pool of desertification land are extremely low or do not have a plant seed of dark root system in the method, before irrigating, must under hollow billet, dig shallow ridges, sow local dark root system plant seed, bury again soil.
