Description
Technical field
The present invention relates to a kind of irrigation system and method, particularly relate to a kind of environment-friendly and energy-efficient moisture movement irrigation system and method.
Background technology
United nations environment conference in 1972 is defined as desertification " land deterioration of the arid that causes due to the factor such as abnormal climate and human activity, semiarid and sub-moistening arid area ".Desertification of land is the generally acknowledged great environmental problem in the world today, is listed in one of global ecological environment ten large problems.Within 1991, United Nations Environment Programme to the assessment of global desertification situation is: nearly 3,600,000,000 hectares of global ccd area, account for 1/4 of Global land area, and have influence on the population (approximately 900,000,000 people) in the whole world 1/6, more than 100 countries and regions.And the speed of desertification expansion is fast, the whole world has the soil of 6,000,000 hectares to become desert every year, and wherein 3,200,000 hectares is pasture, and 2,500,000 hectares is nonirrigated farmland, and 12.5 ten thousand hectares is irrigated land, also has in addition 2,100 ten thousand hectares of soils because of the degeneration cereal of can not growing.Asia is the most concentrated area of population distribution that affected by desertification, and suffering the most serious country of desertification impact is China, Afghanistan, Mongolia, Pakistan and India successively.According to estimates, will there be 1.5 hundred million people to be forced to move in 50 years from now on, annual approximately 26,000,000,000 dollars of the economic loss that the whole world suffers because of desertification.
Desertification Soil not only causes serious land resources to run off, and become the important sources of sandstorm weather, the health of the direct harm humans of high PM2.5 value that the toxic emission that sandstorm and life are produced causes, desertification treatment has been put on the important schedule of various countries' environmental improvement.
Particularly, desertification of land is due to the original water delivery in soil that arid climate and artificial origin cause, contains the destruction of the epidermis system of water, nutrient self-restraint.Soil is generally absorbed and is transported moisture by vascular bundle in the stem of its epidermis vegetation root system, its essence is capillary theory, root system of plant regulates soil moisture by permeable pressure head inside and outside fiber and soil simultaneously, if the earth is likened to " human body ", land resources can be regarded " human body skin " as so, root system of plant just can be regarded " the capillary of human body as, " therefore can say that " capillary " conveying and osmosis have kept moisture and the nutrient of " earth skin ", desertification of land makes root system of plant destroy, capillarity weakens or disappears, water and soil cannot keep, " hematopoiesis blood transfusion " function of " earth skin " its " capillary " is all gone, add original arid climate, make " earth skin " environment move towards vicious circle, therefore " earth skin " ecology is reproduced very urgent.
A difficult problem for desertification and Desertification ecological recovery maximum is lack of water, and water-saving technology mainly contains technology of water catchment, water-loss reducer retaining technology, solid water planting technology, seeping and dripping pipe technology etc. at present.Technology of water catchment is nonsensical in shortage of water resources area; Solid water planting technology is more responsive to water quality, and secondary water absorption character is also subject to precipitation and soil Na, Mg ion side effects limit; Water-loss reducer is only suitable for nursery stock germination period, and growth needs waters large water gaging; Drip, ooze, sprinkler irrigation technique ratio waters water-efficient irrigation, but there is poor water retention property, lay the shortcomings such as cost is high, water utilization is insufficient.In the last few years, " liquid-state mulch film " this method was widely used in arid, semiarid zone, and for fixed sand and dust, prevent and control sandy storm, it is that degradable liquid is spread across in soil in essence, forms protective film, moistens and improve soil after degraded; Also have one to be similar to the method for " diaper ", Water-absorbing high polymer is blended in topsoil, as soil moisturizing agent; The method that also has " artificial vegetation ", is raw material by plant roots, stem, leaf and human and animal excreta and house refuse, by special process, forms " quilt " shape thing and covers desert surface, and plant and crops are grown in the above.Visible " film ", " quilt " method have very strong practicality.
China Mining University opens to increase and aims at " reconciling the water guide coated fiber current situation of soil moisture " (new material industry, the 6th phase in 2008,48-53 page) propose in a literary composition vegetable fiber to carry out the coating of water guide coating, to realize the regulated and controled moisturizing to root system of plant, but its shortcoming is in following shortcoming: one time storage capacity is limited, cannot improve for long-term lack of water present situation; The fibrous material using is vegetable fiber, and the capillarity of raw fiber self is poor; Easily degraded is rotted, and cannot meet and need the long-term long-term environment supplying water that uses.
Therefore also do not have a kind of method can meet the requirement of checking winds and fixing drifting sand completely: 1) fixed or shielding sand and dust; 2) prevent moisture evaporation; 3) moisten and improve soil; 4) realize revegetation; 5) energy-saving and environmental protecting, with low cost.
The present invention proposes the water wetted material micro nanometer fiber felt that utilizes melt electrostatic spinning technique to prepare, utilize its nano level fiber gap and material hydrophily, provide powerful capillary force to carry out transporting of moisture, fibrofelt also will play erosion and the micronic dust carrying of shielding strong wind to sand ground, hydrophobic fiber felt is by the maintenance effect of playing of the moisture that soil is absorbed simultaneously, prevent that moisture is to soil deep percolation, if the soil in this irrigation system application carries out vegetation sowing, finally can realize reproducing of " earth skin " and " capillary " thereof.
