Research On Relationship Of The Characteristic Horticulture Resources Varieties And Soil In Hami Oasis

As the unique geographical location and geographical conditions in Xinjiang, special geographical factors such as light, temperature, water, soil and so on are taken shape. And up to18categories of836specialty varieties of fruit products are conceived by these special geographical environment factors, of which11kinds including Korla Pear, Turpan grapes, Hami Jujube, Aksu Apple, Yarkand Almond and others have been rated as the national geographical indications protection products. Nowadays the cultivation of characteristics horticulture has been another pillar industry in rural economic development after cotton industry in Xinjiang. In this paper, we take the varieties of Hami jujube as an example, to study the relationship between the unique quality and the soil geographic environmental factors in specific growth environment. Historical data, laboratory experiments and field surveys, comparative analysis, geostatistical and spatial data analysis are used to study several aspects:the development process of characteristics horticulture in Xinjiang and Hami oasis; the attribute characteristics and differences of soil physical and chemical properties factor and jujube quality attributes factor in the jujube orchard of the main producing areas and the non-main producing areas in Hami; the spatial distribution characteristics of soil physical and chemical properties factor and jujube quality attributes factor in the jujube orchard of the main producing areas in Hami; the spatial correlation, gray correlation, typical correlation, and regression modeling of soil physical and chemical properties factor and jujube quality attributes factor in the jujube orchard of the main producing areas in Hami. And the folio wings are the main results:1. With the pace of reform and opening, the characteristics horticulture in Xinjiang and Hami oasis is gradually developing, especially in the21st century it enters into a leapfrog development stage. At present, four fruit bases of the northern Ili River Valley, the north of Tianshan Mountains, Tarim Basin in south Xinjiang, and Turpan-Hami Basin in East Xinjiang have been formed in Xinjiang. Hami Basin oasis is gradually dominated by jujube cultivation and along with other fruit products.2. The jujube in Wubu town, the main producing areas have the characteristics of weight, flesh, small nuclear, edible rate, and high sugar. The results of significance test withHuyuan town in the non-main producing areas show that jujube in Wubu and Huyuan town have no significant difference in single weight, diameter, and flesh, however, significant difference exist in the stone, edible rate and the sugar content. And jujube stone inHuyuan town is bigger than Wubu town, but lower in edible rate and sugar content.3. Jujube orchard soil in the main producing areas is mostly sandy and loamy, soil temperature and soil moisture are bigger, and pH, salt content are suitable for jujube growth, and in the nutrient elements, there are low soil organic and available nitrogen, but greater available potassium, and moderate available phosphorus. The results of comparison test in soil physical and chemical properties withHuyuan town in the non-main producing areas show that there is no significant difference in available nitrogen (significance p>0.05), and others such as the soil pH, salinity, organic matter, phosphorus, and potassium exist significant difference (significance p<0.05), of which soil pH, salinity, and available potassium in Wubu town are greater thanHuyuan town, but lower organic matter and available phosphorus.4. The spatial distribution of jujube quality factor in jujube orchard of main producing areas is presented northeast-southwest to the massive distribution law, and there is a strong spatial autocorrelation; most of the property factors in the spatial distribution of soil physical and chemical factors exist spatial autocorrelation in the northwest-southeast direction, and appear distribution phenomenon of massive, patchy and banded in the northwest-southeast direction, and a small part show the spatial autocorrelation in the northeast-southwest direction, and the spatial distribution also present the phenomenon of massive distribution in the northeast-southwest direction.5. The results of space analysis, gray relational analysis and canonical correlation analysis show that:soil moisture of soil physical and chemical properties, pH, salinity have a bigger relationship with the physical nature in the weigh of the unit, flesh, stone and the edible rate of Hami jujube, and a smaller relationship with the sugar content of the biochemical properties in jujube intrinsic, and the soil nutrients of organic matter, available P, available K, available N have a smaller relationship with the quality attributes factors of jujube.
