我区地处中原,农业气候资沅十分丰富。从当前烟草生产看,还没有充分利用这一有利资沅。现根据我区农业气象条件,分析一下烟草生产的丰富汗力。一、早春有充分的光能,热能可以利用1、早春光能、热能的汗力:烟草种子萌发需要的温度较宽,最适温度为25～28℃,最低为10～12℃。我区元月下旬最后一候的平均温度为0.9℃,2月上旬第一候平均温度为1.2℃,到4月第一候平均温度回升到12.2℃在这段期间内,3月初以前的自然温度没有
My area is located in the Central Plains, agricultural climate resources Yuan is very rich. From the current tobacco production, it has not fully utilized this favorable resource. Now according to our district agricultural weather conditions, analyze the rich sweat of tobacco production. First, early spring has sufficient light energy, heat can take advantage of 1, early spring light energy, heat energy of sweat: tobacco germination requires a wider temperature, the optimum temperature is 25 ~ 28 ℃, the minimum is 10 ~ 12 ℃. The average temperature of the last place of the district in late January of January was 0.9 ℃. The average temperature in the first place in early February was 1.2 ℃, and the average temperature rose to 12.2 ℃ in the first place in April. During this period, No temperature
