黑龙江省牡丹江市农作物丰欠气象条件分析(英文)

Analysis of the Weather Conditions in the Abundant or Lean Years in Mudanjiang City of Heilongjiang Province

对黑龙江省牡丹江市农作物丰欠年气象条件进行了分析,结果表明,丰年生长季(5～9月)气温偏高,≥10℃积温偏多,无低温冷害,降水分布适于农情,无干旱与内涝,光照比较充足,即热、水、光三要素配合比较协调;欠年生长季(5～9月)气温偏低,积温少,降水分配失常,或旱或涝,低温、寡照,综合气象条件不利于农业生产。

The meteorological conditions in the abundant or the lean years of crops in Mudanjiang City of Heilongjiang Province were analyzed. The study shows that heat,water and light coordinated closely in the abundant years;on the contrary,the comprehensive meteorological conditions were unfavorable for agricultural production in the lean years. A good yield showed up when there were a higher temperature and a larger amount of accumulated temperature above 10 ℃ with no sign of cold damage,an exactly favorable precipitation distribution with little drought or water-logging and a comparatively abundant light during the growing season(from May to September) . However,the crop yield was low when there were a lower temperature and a smaller amount of accumulated temperature,an abnormal precipitation distribution with drought or water logging and scant sunlight during the growing season(from May to September).
