摘要
从贵州省优质烤烟气候区划指标出发,结合威宁县高海拔地区(1900<H<2300m)种烟的实际情况,详细分析了贵州省优质烤烟气候区划指标。得出表征热量与作物生长发育的关系,不仅要考虑日平均温度和持续天数,还要考虑积温、昼夜温差、地温及叶面温度等。通过分析,对原指标中成熟期平均温度、大田生长期温度、旺长~成熟期天数等指标进行了修正。补充≥10℃活动积温≥2200℃,移栽期日平均气温≥14℃,月平均日较差≥8℃等指标。
With the reality of planting tobacco in high elevation area:Weining county,Guizhou province (1900-2300m),the classification indexes of the climate regionalization of high quality tobacco were analysed in detail.The relationship between the surface heat and the growth of tobacco was given.The results show that not only the daily average temperature and its lasting time can be used to the climate regionalization indexes,but also the accumulated temperature,the temperature difference between day and night,the soil surface temperature and leaf temperature should be considered.The formar indexes of the average temperature in the mature period,the temperature in growth period,and the lasting days from growth to mature were corrected,and some supplemental indexes were suggested.
