连平鹰嘴蜜桃种植的气候适宜性分析

采用连平县1981—2011年的地面观测气象资料,结合连平县气象局鹰嘴蜜桃课题研究组实地调查观测的鹰嘴蜜桃物候期资料及生长发育情况,运用统计学方法从气候基本要素气温、降水等方面分析该县适宜鹰嘴蜜桃种植的气候条件,结果发现该县北部上坪镇的山区坡地,适宜鹰嘴蜜桃的种植;鹰嘴蜜桃生产基地应选择在海拔较高、坡度平缓并且向阳的山坡地;本地正常年份开花时间在2月中旬初到3月上旬中期,鹰嘴蜜桃开花期呈现提前趋势;本地鹰嘴蜜桃种植仍有不利气候因素存在,包括冰雹、雷雨大风和骤雨、干旱、病虫害等,因此要做好相应的防御措施,尽量减少及避免损失。总之,连平北部独特的气候可为鹰嘴蜜桃的高产、高质提供可靠保证。

Analysis of the Climate Adequacy of Growing Peach in Lianping County

Using the surface observations of Lianping in 1981--2011, this work statistically studies, together with observed phenological data and growth, the basic climate conditions of air temperature and precipitation for growing a local peach in the county. The findings are listed as follows. The sunny slopes of the hills in the northern part of the county, which are high above sea level and gently inclined, are suitable for growing the peach. For a normal year, the local blooming time spans from mid-February to early March but tends to occur on increasingly early dates. For the local peach, unfavorable climatic conditions include hails, thunderstorms, droughts and pests. Appropriate counter-measures should be taken to minimize losses that come consequently. In summary, the climate is so unique in the northern part of Lianping that it is a reliable natural resource for producing high-yield and good-quality local peach.
