气候条件对棉花产量有决定性影响。对安阳市丰歉年型进行气候分析表明,丰年具有5月和9月温度高,生长季各月日照多,雨量分布均匀的特征。而5月和9月月平均气温低于21℃,7～9月各月日照时数低于190小时,8月雨量大于150mm或少于100mm,则不利于高产。对丰歉年型进行分析和预测,可为及时采取合理栽培技术措施趋利避害提供依据。
Climatic conditions have a decisive impact on cotton production. The climatic analysis of Anyang apricot type indicates that there are many features in abundance, such as high temperature in May and September, more sunshine in each growing season, and uniform rainfall distribution. While the monthly average temperature in May and September is less than 21 ℃. The sunshine duration in each month from July to September is less than 190 hours. When the rainfall in August is more than 150mm or less than 100mm, it is unfavorable to high yield. The analysis and prediction of the abundance and year-old type can provide the basis for adopting reasonable cultivation techniques and measures in a timely manner and avoiding disadvantages.
