In recent years, the water - saving and control irrigation technique of rice has diverted from plot experimental and demonstration to lare scale. and has got remarkable economic and social benefits. amed at the characteristics of this irrigation area, optimal selection for water - saving techniques of rice, deciding the amout of leaching water and irrigation modles, investigating the adaptability of the water - saving and control irrigation technique in saline land. studying the increase in production mechanism of the technique are important to extend the technique, to better and develop saline land as well as slick spots. according to the results of field experiments, optimization study was conducted on the water - saving irrigation technique of rice in saline land, the effects of different water - saving irrigation techniques on the physiological indexes and yield of rice were systematically analyzed. by using mutiplepurpose fuzzy optimization method, better. water - saving irrigation technique was selector out, that is. the control irrigation technique in rice. the mechanism of it was analyzed from the aspect of the physiological and ecological saving water of rice to provide the implemental process and technical point ; throgh the quantitive analysis and comparision on control irrigation and control class ( flood irrigation ), high production and quality mechanism of the technique was analyzed in terms of physiology indexes of rice, the variation of soil moisture, the pest resistance and the lodge resistance, the change of soil temperature in paddy fields. the yield constitutive factors, the quality of rice and so on. in saline land. control irrigation and intermittent leaching modles were adopted to validate the adaptability of the technique in irrigation of rice in saline land, to analyze rice ' s physiological - ecological indexes and the change of soil salt content under the conditions of control irrigation leaching of rice and and to provide control irrigation and combined modle of intermittent leaching to adapt to different conditions

The traditional homogene cloning method was modified on two aspects : first, homo - primers was designed at the sites with minimum degeneracy instead of maximum homology, secondly, some " n " bases were replaced with inosine in degenerate codes, resulting hi the degeneracy reduced from over 1000 times to below 100 times
