2014年后大滩红萝卜生育期水热条件分析

Analysis on The Hydrothermal Condition of Carrot Growth Period in After Big Beach in 2014

文章利用2014年4—10月察右中旗乌素图区域自动气象站的气温和降水以及察右中旗国家气象站的地温等气象资料,采用对比分析方法,从热量和水分两个方面对2014年察右中旗后大滩红萝卜生育期气象条件进行分析。结果表明:2014年察右中旗后大滩地区的热量条件基本满足红萝卜的生长需求,而水分条件仅在茎叶生长期和收获期能满足,在播种期、出苗期和肉质根膨大期降水少,土壤含水率小,不利于红萝卜播种、出苗和肉质根膨大,需做好期间的灌溉保墒工作;在收获期时有阴雨天气出现,对红萝卜的收获有一定的影响。同时分析了异常水热天气对红萝卜生育过程的影响以及应对的栽培措施,为红萝卜生产中合理利用气候资源,趋利避害提供参考依据。

Using the meteorological data of the temperature and precipitation monitored by the zone automatic station in Wusutu and the geothermal monitored by the national meteorological station from April to October in 2014 in Chayouzhong county, Using the comparative method, this article discussed the meteorological condition from the two aspects of heat and moisture during the carrot growing period in After Big Beach in Chayouzhong county in 2014.The results showed that the thermal condition basically meet the demand for the whole growing process of carrot in After Big Beach in Chayouzhong county in 2014, while the water condition only meet the demand for the phase of stems and leaves growing and harvest period, less rainfall and small soil moisture content in the sowing, seedling and fleshy root enlargement, it was unfavorable for carrot planting, emergence and fleshy root enlargement, it needed irrigate and maintain timely soil moisture; it arise rainy weather from time to time during the harvest period, it influenced the carrot harvest. At the same time, analyzed the affect on the reproductive process of carrot and proposed the measures to deal with the cultivation under the abnormal hydrothermal condition. It provided a reference for planting the carrot so as to utilizing legitimately the climate resources and avoiding disadvantages.
