摘要
为分析陕北高原地区冻害对果树的不利影响,利用陕北黄土高原地理位置、气候、地温、气温的调查方法,总结出陕北黄土高原地区年平均地温11~6℃,春季地面增温较快,幅度为6~8℃,秋季地面降温迅速,幅度为7℃,冬季低温期长,地温年差较大,不同深层地温也有变化的气候特点。冬季容易低温冻害,春季容易发生倒春寒,在试验示范的基础上提出了冻害来临前果树的防寒、灾后补救等综合防治措施,以供果农参考。
In order to analyze the adverse effects of freezing damage on fruit trees in northern Shaanxi Plateau,the average annual ground temperature in the Loess Plateau of northern Shaanxi was determined to be 11~6℃by using the survey methods of geographical location,climate,ground temperature and air temperature.The ground temperature in spring increased rapidly with a range of 6~8℃,and the ground temperature in autumn decreased rapidly with a range of 7℃.Winter is the lowest(low temperature period is long),the annual difference of ground temperature is large,different deep ground temperature also has changes.It is easy to have low temperature freezing damage in winter and reverse spring cold in spring.Based on the experiment and demonstration,the adverse effects of freezing damage on fruit trees and the comprehensive control measures were put forward.
