Description
Technical Field
The invention relates to a method for rapidly changing fertile farmland in desert around a water source area of oasis in southern Xinjiang.
Background
Although southern Xinjiang has abundant land resources, due to the severe arid desert environment, the southern Xinjiang has rare vegetation, frequent wind and sand, uneven water resource distribution and frequent natural disasters, and further has the situation that the land is desertified and salinized in a large area and is difficult to be utilized. Reports about 87 km of land area desertified in southern Xinjiang at present230 percent of the total area of the national desertification land, 60.4 percent of the area of the brand new ARUM and 75 percent of the total area of the southern ARUM, wherein the area of the southern ARUM is up to 43 km2The soil composition occupies 38 percent of the total area of the southern Xinjiang land, the utilization rate of the southern Xinjiang land is only 17.1 percent, the cultivation rate is only 1.9 percent, and soil components formed by the original ecological environment mainly comprise fine sand, the soil formation process of soil organisms is weak, organic matters are poor, surface substances are easy to corrode by wind, the fertility is low, and a lot of agricultural experts have considered that the soil composition is not suitable for large-scale agricultural production and operation. The fact proves that the ecological environment of southern Xinjiang is quite severe, the relationship between desert and oasis is that the relation of 'you move in and go out', and the key is how to transform and control the southern Xinjiang desert to make the desert become an extremely mobile oasis.
Desert is a natural product, and people cannot radically cure desert, but 'consequent, improvement of land selection and time selection' makes local artificial benefits impossible. Through the networking of desert forests, land planning and leveling, natural snow water and locally abundant underground water are fully utilized, reasonable desert development is realized, field improvement is achieved, and therefore the problem of serving local economic development is faced by human beings.
Because the land development has the characteristics of high investment, slow income, large risk and strong unpredictability, developers usually only consider the pre-ocular benefits and are reluctant to carry out 'long-line' investment; secondly, most land developers in reality have low own scientific culture quality, so that the existing desert land cannot be scientifically utilized, and in addition, since a long time ago, China lacks targeted research work in the process of desert development and utilization, so that the existing desert-to-improved land mode is simple, lagged, without systematicness and foresight, for example, the eastern red 55 old-style track bulldozer or even a manual operation mode is adopted, the technology in the process of transformation lacks standardization, an unreasonable irrigation salt washing mode is adopted, comprehensive ecological environment protection is neglected, the phenomena of predatory development and utilization of land resources such as excessive land, excessive felling, excessive grazing and the like occur in some places, the consequences are that land desertification, water and soil loss, grassland desertification and abandoned land cultivation are more serious, and particularly, the phenomena of secondary development of degraded land or planting bases with poor early improvement effects exist in reality, not only causes the investment of manpower, material resources, financial resources and the like in the early stage, including the waste of water and soil resource investment and the damage of the ecological environment of a cotton area, but also causes the improvement of the desert into the high-standard fertile farmland period extension, thereby delaying the development opportunity.
Through field investigation of similar areas at home and abroad, experts generally consider that: compared with the ecological environment of southern Xinjiang in other desert regions of the world, including the agricultural natural ecological environment of peripheral countries such as Hasakstein, Girgistan, Targistan, Pakistan, India and the like which are bordered in southern Xinjiang, the ecological environment of southern Xinjiang has obviously poorer environmental conditions of resources, low development value and large risk. At present, no example of successful large-area water and soil development similar to the southern Xinjiang ecological environment area exists abroad.
According to the method, through selecting a desert area to be improved, building irrigation and drainage channels, roughly flattening and finely flattening, turning over and exposing to the sun deeply, washing with saline and alkaline in winter, planting two crops of oil sunflower, corn, beet or other green manure plants with strong salt resistance in one year, selecting and planting grains or cotton crop varieties with relatively strong salt resistance, and performing fertile field management according to a high-yield, high-quality and high-efficiency conventional management method of local corresponding crops, the desert around oasis in Xinjiang is reformed into a high-standard fertile field in 3-4 years, so that the purpose of realizing the high yield and high quality of grains and cotton in the field is facilitated, the income of farmers in south China is increased, and the effect of consolidating the national important grain and cotton base is exerted.
At present, the south China industry is quite laggard, the per capita cultivated land is 2.23 mu, most farmers only rely on land income to maintain life, however, agriculture is an absolutely leading industry in the area, the income of farmers is single, so that up to 217.24 million of 698.93 million people in the area are the rural poverty-relieving objects, the per capita cultivated land area is increased, a foundation is laid for large-scale and mechanized agricultural production, the urgent need for promoting local agricultural development and solving the problem that the farmers are poverty-relieving and rich is solved, the development of the south China economic society is further promoted, the method is related to the realization of the new-stage south China poverty-relieving and strengthening target, the implementation of the strategy of 'Xinjiang and rich side' is related, the group of nations is maintained, the border defense is consolidated, the stability and the long-term safety of the Xinjiang society are realized, and the method has extremely special significance.
