研究分析了在和田地区核桃幼树抽条与诸气象因子的关系。结果表明:(1)日平均气温、日平均地温、日较差、日蒸发量、日平均风速、大气湿度等因子在达到任一极端值时,均不能使核桃幼树抽条;(2)冻土深度与核桃幼树抽条率极显著相关;(3)通过回归分析表明,落叶后的负积温、10cm地温负积温、蒸发量、低湿(相对湿度<30%)天数、高风速(高于月平均风速)天数和冻土深度与核桃幼树抽条率之间存在极显著的相关关系;(4)通过分析发现,低湿天数、低温负积温和高风速天数是影响核桃幼树抽条的主导因子,当达到78d、-142.2℃和68d时,使核桃幼树抽条;(5)通过试验和研究,提出了防止措施。
The relationship between walnut saplings and weather factors in the Hetian area was analyzed. The results showed that: (1) Saplings of walnut could not be obtained when the daily average temperature, daily average ground temperature, daily diurnal variation, daily evapotranspiration, daily average wind speed, atmospheric humidity and other factors reached any extreme values; (2) (3) The regression analysis showed that the negative accumulated temperature after 10 cm, the negative accumulated temperature at 10 cm, the evaporation, the number of days with low humidity (relative humidity <30%), high wind speed (high (4) According to the analysis, it is found that the number of days with low humidity, negative temperature and high wind speed is the most influential factor affecting the walnut saplings The dominant factor of the walnut tree was drawn when it reached 78d, -142.2 ℃ and 68d; (5) Preventive measures were put forward through experiments and studies.
