以新疆和静县沙壤土、风沙土、砾土质戈壁等3种典型立地条件为研究对象,分析了杨树生长量的影响因素,以期为杨树的推广种植提供参考。结果表明:3种立地条件下,乌拉斯台农场(沙壤土),地力优,杨树生长好,其次为夏孜尕提(砾土质戈壁),最差为沙河子(风沙土);相同施肥条件下,施用复合肥时杨树长势更好,且在施用复合肥100g.株-1时,效果达到最佳。土壤理化性质分析表明:土壤有机质含量与土壤pH值存在负相关,全氮、全磷与有机质呈极显著相关,土壤有机质、全氮与土壤容重都呈显著负相关,但土壤全钾含量正好相反,即全钾与土壤容重呈显著正相关。
Taking three typical sites of sandy loam, aeolian sandy soil and gobi soil in Hejing County, Xinjiang as the research object, the influencing factors on the growth of poplar were analyzed in order to provide reference for the poplar planting. The results showed that under the three site conditions, the Wulasitai farmland (sandy loam soil) had the best soil fertility and poplar growth, the second was the Ziziyatiti (gravelly soil Gobi), and the worst was Shahezi (aeolian sandy soil). The same fertilization conditions Under the application of compound fertilizer poplar growing better, and the application of compound fertilizer 100g. Strain -1, the effect is best. The analysis of soil physical and chemical properties showed that there was a negative correlation between soil organic matter content and soil pH, total nitrogen and total phosphorus were highly significant correlated with organic matter, soil organic matter, total nitrogen and soil bulk density were negatively correlated, but soil total potassium content was the opposite , That is, total potassium and soil bulk density was significantly positively correlated.
