气候条件对水稻的生长发育、区域分布、栽培技术有着十分密切的关系。特别是山区的气象条件远此平原地区复杂,更要认真分析,严肃对待,防止片面性,减少盲目性,才能确保双季稻安全生产和稳产高产。一般来说,每个地区都有其基本的气候特征和规律,但在不同的年份之间又有许多特殊的变化。北峯山区也不例外。例如在常年,北峯山区的日平均气温到四月上旬就开始稳定在11～15℃,此时播种育秧应该是安全的。但是一九七二年在三月底至四月上旬连续出现三次冷流,四月第一、二候的平均气温分别下降到7.2℃与10.1℃,比正常的一九七四年同期分 Climatic conditions have a very close relationship with rice growth and development, regional distribution and cultivation techniques. In particular, the meteorological conditions in the mountains are far more complicated than those in the plain areas. In addition, careful analysis and serious treatment should be taken to prevent one-sidedness and reduce blindness in order to ensure the safe production and stable yield and high yield of double cropping rice. In general, each region has its own basic climate characteristics and laws, but there are many special changes between different years. North Peak Mountain is no exception. For example, in the perennial year, the average daily temperature in Beifeng Mountain Area starts to stabilize at 11 ~ 15 ℃ in early April, at which time sowing seedlings should be safe. However, three consecutive cold flows occurred in late March and early April in early 1972. The average temperatures in the first and second months of April dropped to 7.2 ° C and 10.1 ° C, respectively, from the normal figure for the same period in 1974
