| 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，加强对灾害的监测预报工作．

The Influence of Climatic Changes on the Production of Crops in Ningbo |
| |
| Abstract: | This article analyzes the climatic conditions a nd trends from 1953 to 1998,
especially that in 1990's. The result shows that th e average annual hours of sunlight has
decreased, but the average annual tempera ture has increased; and that the climatic-caused
disasters damage the crop pr oduction seriously. Several suggestions are provided against
the climatic c hanges such as developing different kinds of three-season crops in a year;
pos tponing 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 a nd forecast systems for climatic disasters. |
