| The agricultural production of Yanchi county that lies in southern Ningxia receive water resource to be seriously insufficient, and the limited gathering rainfallon space-time would aggravate soil erosion. The realistic productivity of the whole county crops is very low, and traditional agricultural mode and thinking of development, hardly break thinking heavy that caused by aridity shoulder pigeonholing and small-scale peasant economy bottleneck. High starting point development "against the gradient has" region characteristics. The goal is orientated as the export-oriented tomato base that exports, the course of it is difficult to starting, it is very crucial to hold and explore the technical support system identical with local resource distribution , with effective economy of lasting orientation of the goal conscientiously. For these reasons, in 2001 the author had put forward in the idea of planting the tomato of local scale. Through 2001a-2004a ,from the practical exploration of such key links ,as construction of the tomato base, the chosen of links, the complete forming of technology and scale potentiality of the construction , etc., the basic conclusions drawn are:1. Two tomatoes have been introduced and succeed in the locality in new varietiesThe Yanchi County is located in the North the dark edge zone of plain Mao Wusu desert, which has great height above sea level, great difference in temperature day and night, the sufficient sunshine, little industrial pollution. The Yanchi county can produce various tomato types, which being high in quality, nutrition best in quality , color and luster fresh , good flavor, the tomato products with various type meeting the needs of international market, such as the medium-sized fruit Israeli R-144, heavy 85-180g of simple fruit, the Dutch agate tile of medium-and-large-sized fruit, heavy 100-200g of simple fruit.2. New varieties combine new technologies have heavy potentiality to be exploitedThe development would be in high-level and high efficiency of, as the continous introduction of the high-quality variety , low cost of irrigation and manure regulation ,and deepen control of technology . The development is a comparative advantage to increase the income of peasant in a short time, and there are tendency resources developed further.Being technical support system would be taken intensive objective reality still, The plan should follow the unbalance development principle , and establish long-term idea on " quantity much worse than of fine quality , do much worse than doing strong" . If apiary expanding the scale meet an urgent need,which is not according with " crossing over " of the technological strength , the consequence is dangerous.3. It is its base of having the scale that the industry's internal force of tomato with developing workforce resources at the core cultivatedAt present, 1 workforce in the county of Yanchi can bear the weight of facility area 0.05-0.06 hm2,and there are 316 workforces now on the base. Actual one people can bear the weight of facility area 0.026hm2. This is 47.3% of the bearing weight strength , and it improve the bear of the weight of the percentage point. Cooperating with drip irrigation technology , can stimulate base expand to introversion. Making the corresponding preferential policy and encouraging the technological immigrant, let them enable to go and live with theirs relatives or friends and enter the tomato base. Relatively stable technological immigrant can engaged in to " exchange work " and provisional to be hired while plantinggreenhouse tomato in the tomato base , for instance covering draw and cover grasses ,which enable to dispel the worrylacking of peasant households who lacing the strong labor power or male labor's regular who works out. Joining constantly, employ and employee cost relatively low, have been acceptable by both sides, and can accelerate the land circulate.4. Postponement of "greenhouse + large canopy " produce mode to raise basic guarantee and the scale of industryThe application which is postponed the production technology is the shortcut that the air conditioner accuses of while realizing the water resource. Choosing interval of expanding according to source of water ,it is cooperated with portable large canopy or build portable large canopy group between two greenhouse. Early spring, is it delay a great stubble of culture (propose variety choose 73-41 Holland ) in is it irritate terms can carry on technological demonstration practice to mend summer , autumn to exceed .5.It is the foundation in stabilizing the development of the greenhouse to utilize the water cellar to buffer the law and solve the problem of source of waterBy choosing survey and study to tomato old canopy culture canopy type tentatively structure and adaptability demonstration that variety, this thesis think that expand the interval of the design of greenhouse when choose the source of water on the irrigated area of motor-pumped well, and cooperate with portable large canopy or build portable large canopy group between two greenhouse. It is the water quality of motor-pumped, number of times and getting long to restrain facility technology from to yellow water to be used and fully play benefit. Portable large canopy and greenhouse alternate structure 2:1 or 3:1 proportion. Utilize the large canopy as the surface of water collecting, raise yellow water to irrigate and combined with irradiation to mend by cellar by kilning. Jointly use of groundwater, yellow water , natural precipitation, Introduce in Beijing Kefa drip irrigation system which conformity with national conditions. Carry on large canopy in early spring stubble , greenhouse in autumn and winter stubble tomato drip irrigation culture. It is produced by a large margin yellow water conservancy spend concrete imagination of efficiency a kind of better design to promoting anniversary to develop to depend on, design plan this, it can drip view irritate system to hit mineralization motor-pumped well water usable result, efficiency to examine further also at the same time.The construction of tomato base should be raised to the strategic height of the county industry. The key organization of industry's technological development of tomato that government's and market leading should be set up . The scientific and technological service entity stressing practical results should be made up too, which include a scientific research (standardization technological demonstration base ), train (educates ) popularizing and producing are combined closely. The technological resources should be combined; the technology popularization system would be vitalized. The resource rational distribution would be realized. The technology popularization system would be strengthening. While the technological key points to standardized , industry's development of tomato is stepped into regarding increasing peasant's income as the core be proposed. Relation on the physiology control of salt and alkaline land, the transformation of middle-and-low-yielding fields , the "localization" of fungus grass resource, the circulation type economic system be channeled with the " fungus grass industry -ecological fungus industry -the utilization that abolish the fungus material", Yanchi county should form red industry and the combining organically of white industry, in ordering to strengthen the motive force that the export base of local tomato develops continuously.
