花生是我省主要油料作物.分布于闽东南沿海一带,约占全省种植面积70～80%.播种时,常因遇到北方冷空气入侵,造成低温阴雨不良天气,而引起不同程度烂种缺苗.推迟播种期虽较安全出苗,但迟播缩短花生生育期,推迟开花结荚日期,易受夏旱影响,引起秕果多而减产.花生什么时候播种能安全出苗,达到增产,这是生产上急需解决的问题.我所多年来进行花生播种期试验及调查群众经验.现结合历年来气象资料,对花生播种期与农业气象条件的关系,初步分析如下.
Peanut is the main oilseed crop in our province, distributed in the coastal area along the southeastern Fujian Province, accounting for 70-80% of the planting area of the province .During the planting, peanut is often invaded by cold air in the north, Lack of seedlings. Delayed sowing period, although more safe emergence, but delayed sowing shortened peanut growth period, postponed flowering pod date, susceptible to the impact of summer droughts, causing more fruit and yield reduction .When peanut sowing can be safe to emerge, to increase production, which Is the urgent need to solve the problem of production.I have conducted many years of peanut sowing test and survey the masses experience.Combining meteorological data over the years, the relationship between the sowing date of peanut and agricultural weather conditions are as follows.
