摘要
重点分析了宁波 1990— 1998年的气候条件和变化趋势 ,从中发现日照数呈下降趋势 ,而年均气温呈上升趋势 ,这些变化加上气候灾害对农作物生产影响严重 .据此现象 ,提出在种植结构调整过程中 ,要发展多种模式的三熟制 ,适当推迟冬种作物播种期、秋粮收获期 .选育多种生态类型的品种 ,抗逆性强的品种 ,增强抵御自然灾害的能力 .选育低光呼吸、低光补偿点的品种 ,克服日照减少对产量的影响 .还要加强农田水利建设 。
This article analyzes the climatic conditions and trends from 1953 to 1998, especially that in 1990's. The result shows that the average annual hours of sunlight has decreased, but the average annual temperature has increased; and that the climatic caused disasters damage the crop production seriously. Several suggestions are provided against the climatic changes: such as developing different kinds of three season crops in a year; postponing the sowing time of winter crops and harvest time of autumn crops ; selecting different varieties with different ecological characteristics and resistance to unsatisfactory climatic conditions; developing and improving irrigation and drainage systems and forecast systems for climatic disasters.
