为了解杏幼果脱落与温度的关系,该试验对设施杏在不同栽培模式下的温度做了比较研究,通过对当地近5年的产量、气象资料进行统计研究,分析出了露地、设施栽培条件下的杏生长的最佳温度范围并与对照进行比较,提出杏在花期、低温敏感期和第1次幼果脱落期各阶段的适宜温度范围、次适宜温度范围、危险温度范围的概念。结果表明:3个不同物候期适宜温度的最低和最高温度范围为1.9~7.5℃和10.3~18.6℃、3.1~7.9℃和13.1~18.8℃、4.1~10.4℃和15.0~23.9℃;计算出各阶段适宜温度范围内所占天数的百分率分别为57.5%、50.0%;66.7%、63.3%;60.0%、60.0%。表明各阶段适宜温度范围内所占天数的百分率应大于或等于60%;次适宜范围的天数所占的百分率控制在5.8%~10.0%,危险范围的天数在10.0%以下为宜。
In order to understand the relationship between apricot fruit drop and temperature, this experiment made a comparative study on the temperature of apricot in different cultivation modes. Through the statistical research on the yield and meteorological data of the past five years, Apricot growth apricot under the conditions of the best temperature range and compared with the control apricot in flowering, low temperature sensitive period and the first off the young fruit stage of the appropriate temperature range, sub-optimal temperature range, the concept of dangerous temperature range. The results showed that the minimum and maximum temperature range of suitable temperature for three different phenophase was 1.9 ~ 7.5 ℃ and 10.3 ~ 18.6 ℃, 3.1 ~ 7.9 ℃ and 13.1 ~ 18.8 ℃, 4.1 ~ 10.4 ℃ and 15.0 ~ 23.9 ℃; The percentage of days covered by the appropriate temperature range was 57.5%, 50.0%, 66.7%, 63.3%, 60.0% and 60.0%, respectively. Indicating that the percentage of days covered by the appropriate temperature range should be greater than or equal to 60%; sub-optimal range of the percentage of days controlled at 5.8% to 10.0%, dangerous range of days below 10.0% is appropriate.
