以银白杨×新疆杨的8个杂种无性系为材料,研究其在新疆北屯、玛纳斯和伊犁试验区的生长特性差异及其与环境因子的关系。结果表明:银白杨×新疆杨8个杂种无性系的高生长、径生长在北屯、玛纳斯和伊犁3个试验区均存在差异。8个无性系材积增长量的顺序为北屯试验区>玛纳斯试验区>伊犁试验区,在所有试验无性系中,北屯试验区的108号无性系的材积增长量最大,为0.774 4m3,材积增长量最小的为玛纳斯试验区的184号无性系,仅有0.101 3m3;不同试验区的温、湿条件是影响银白杨×新疆杨杂种无性系材积增长的主要气候因素;影响无性系生长的土壤主分量因子在北屯试验区为土壤有机质、土壤全氮、土壤全磷、土壤速效氮、含盐量和含水率;在玛纳斯试验区为土壤有机质、土壤全氮、土壤全钾、土壤速效氮和土壤速效钾,在伊犁试验区为土壤有机质、土壤全氮和土壤速效氮;综合材积与气候、土壤因子,8个无性系中,以108和527无性系的生长为最佳。
Eight hybrid clones of Populus alba × Xinjiang poplar were used as materials to investigate their differences in growth characteristics and their relationship with environmental factors in Beitun, Manas and Yili experimental areas of Xinjiang. The results showed that the height growth of eight hybrid clones of Populus × Populus × xinyao × Populus × Poplar × Poplar × Poplar × Poplar × Poplar × Poplar × Poplar × Populus deltoides were significant differences in diameter growth among Beitun, Manas and Ili. The order of volume increment of eight clones was Beitun, Manas, Yili, and among all the tested clones, the volume increase of No 108 clone in Beitun was the highest, 0.774 4m3 , And the smallest increment of volume was Manchurian 184 clones, only 0.101 3m3. The temperature and wet conditions in different experimental areas were the main climatic factors that affected the volume growth of Populus × sibirica × Xinjiang hybrid clones; In the Beitun experimental area, the main component factors of soil growth were soil organic matter, soil total nitrogen, total phosphorus in soil, available soil nitrogen, salinity and water content. In Manas experimental area, soil organic matter, soil total nitrogen, soil Total potassium, soil available nitrogen and soil available potassium. The soil organic matter, soil total nitrogen and soil available nitrogen in the experimental area of Ili, the volume of the integrated volume and climate, soil factors, 8 clones, the growth of 108 and 527 clones optimal.
