利用冬麦区冬小麦生长期间农业气象要素、气象卫星植被指数 ,地面观测站网的农情资料 ,对 1998/ 1999年度冬麦区农业气象条件及其对小麦生长发育和产量的影响进行了综合分析 ,结果表明 1998/ 1999年度冬麦区虽受秋冬季干暖天气气候的严重影响 ,小麦长势极不均衡 ,但入春以后小麦关键期的光温水条件利于小麦生长发育 ,尤以 4月份以后的气象条件最为优越 ,在产量结构中以粒重见长 ,最终获得了较好收成。
Based on the agricultural meteorological elements, the meteorological satellite vegetation index and the information of the agro-pasture during the growth of winter wheat in the winter wheat area, the author analyzed the agrometeorological conditions in winter wheat area in 1998/999 and their effects on the growth and yield of wheat The results showed that although winter wheat was affected severely by winter / warm weather in 1998/999, the wheat growth was extremely uneven. However, the conditions of light, temperature and water in key period of wheat after spring were favorable to the growth and development of wheat, especially after April The meteorological conditions are the most superior, with the grain weight in the yield structure, and finally obtained a better harvest.
