为了恰当的安排冬萝卜适宜的栽培季节,作者通过资料的整理探求我国冬萝卜在营养生长期中所要求的最适月平均温度及其适应范围。作者从我国蔬菜的地理分布区中,选出15个代表点,以当地栽培较多的冬萝卜品种为材料,根据各地最适播种期和收获期对照当地多年积累的月均温、制成我国各地区冬萝卜栽培季节月均温表(表1)。并根据该表的数据绘制出冬萝卜栽培的月均温适应范围图(附图)。从图中按照冬萝卜对月均温能适应的趋势,划出最大和最适月均温的范围。最大范围的制定是按照有20％的代表点在
In order to arrange suitable winter carrot cultivation season, the author through the data to find our country winter radish in the vegetative growth period required by the most suitable monthly average temperature and its adaptation range. The author selects 15 representative points from the geographical distribution of vegetables in our country and takes the local cultivated winter radish varieties as the materials and makes the national average temperature according to the local average monthly temperature accumulated by the local sowing and harvesting periods Winter radish area cultivation season monthly temperature table (Table 1). And according to the data table drawn winter radish cultivation average monthly temperature adaptation map (with photos). From the figure in accordance with winter radish on the monthly average temperature to adapt to the trend, draw the maximum and the most suitable monthly average temperature range. The maximum range is set according to 20% of the delegates at
