摘要
温度是设施杏栽培成功与否的关键因子,通过对近10年气象资料的统计分析和不同棚体温度的对比分析,对花期、低温敏感期和第1次幼果脱落期3个阶段的日最低、最高温度范围进行了科学的界定,并提出了适宜区、次适宜区和危险区的概念。3个阶段适宜区最低、最高温度范围分别是2.1~7.7℃和13.0~18.8℃;3.2~8.1℃和13.3~19.0℃;4.3~10.6℃和15.2~24.1℃。同时各阶段在该范围的天数以不低于60%为宜,危险区所占天数应不超过10%,且避免出现“致死”的高温和低温。
Temperature was the critical factor to decide whether facility for growing apricot success or not. Near ten year's weather data were analysed and the temperature in different sheds were compared with each other. Three concepts were put forward according to temperature,i, e. suitable scope, less suitable scope and dangerous scope. The lowest and highest temperature in suitable scope among the three period of florescence stage, sensitive period to low temperature, and the stage of first fruit dropping was 2.1 - 7.7 ℃, 13.0- 18.8 ℃, 3. 2- 8. 1 ℃, 13.3- 19.0 ℃ ,4.3-10. 6 ℃ and 15. 2-24. 1 ℃ ,respectively. In suitable scope,the days of daily temperature being in the scope in the right stage takes account for not less 60% of all days,and the days in dangerous scope,not more than 10% ,at the same time,the fatal high temperature and low temperature should be avoided.
