摘要
利用GIS系统和气候学相关原理,建立哀牢山西坡气温、日照时数、降水量、相对湿度的空间分布模型。结果显示以坡头为代表的哀牢山西坡种植区,温度和降水总体适宜咖啡生长:春季光照强,降水少,气温回升迅速,咖啡干旱风险较高;夏季降水充沛,有利于果实膨大,中低海拔地区应注意防范病害;秋冬两季温差大,早晚多雾露,有利于糖分等干物质积累,形成高品质咖啡,露天晒场应注意早晚防潮;冬季霜冻风险较低,但不宜在凹地、阴坡地及高海拔地区种植。引进新品种咖啡时,应注意品种的抗寒性和抗锈性。
The spatial distribution model of temperature,sunshine hours,rainfall and relative humidity on the western slopes of the Ailao Mountains was established based on GIS system and relevant principles of climatology.The results showed that the temperature and rainfall in Potou as the representative on the western slope of the Ailao Mountains is suitable for coffee growth.In Spring,there is a water risk because of the strong sunshine,less rainfall and quick rise of temperature.But in Summer,there is a plentiful of rainfall and berries are favorable with it.Pests and diseases should be focused at this time in low and middle elevations.There is great difference in temperature between Autumn and Winter,fog and dew in the morning and evening can make accumulation of sugar and other dry matter for high-quality coffee.Measures should be taken against wet during drying outdoor in the morning and in the evening.Although low risk of frost damage in Winter,coffee planting in concave,shady slopes and high altitudes should be avoided.Coffee varieties should be selected with high cold resistance and rust resistance when bred new ones anytime.
