设施油桃抗风险栽培温度模式研究

Research on Temperature Model of Nectarine in Anti-risk Facilities Cultivation

温度是设施油桃栽培成功与否的关键因子,通过对近十年气象资料的统计分析和露地及设施生产点的对比分析,对油桃花期、低温敏感期和第一次幼果脱落期3个阶段的日最低温度、日最高温度范围进行了科学界定,提出了油桃设施栽培的温度适宜区、次适宜区和危险区的概念,其温度适宜区范围分别是3.3～8.4℃和13.5～19.3℃、4.5～10.9℃和15.3～24.6℃、5.6～11.4℃和17.2～25.9℃;同时各阶段在该范围的天数以不低于60%为宜,危险区所占的天数不应超过10%,且避免出现"致死"的高温和低温。

Temperature was the key factor for nectarine（Prunus persica L. var. nectariana）facility cultivation. According to the statistical analysis of the ten years weather materials, the lowest day temperature and the highest day temperature of the florescence, low temperature sensitive date and the first fruit falling infancy were determined. Several conceptions about nectarine cultivation such as suitable area, less suitable area and dangerous area were proposed. The temperature range was 3.3～8.4℃,13.5～19-3℃,4.5～10.9℃,15.3～24.6℃,5.6～11.4℃,17.2-25.9℃ and 17.2-25.9℃ respectively. The days in the suitable temperature range should take not less 60% of all days and the days in dangerous area were not more than 10 %. The fatal high temperature and low temperature should be avoided.
