河南省麦田春旱的原因及对策

The Analysis of Spring Soil Drought of Winter Wheat Field and Its Countermeasures in Henan Province

根据麦田春旱发生的频率和强度,将河南省划分为极旱麦区、重旱麦区、中旱麦区、半旱麦区和轻旱麦区5个类型.研究结果表明,春旱发生的主要原因是生产上对春水的利用不够合理,其次是春季自然降水较水.采取适宜的栽培措施,如田间覆盖、镇压与中耕等,充分蓄纳雨水,最大限度地减少水分散失。

The spring soil drought of winter wheat field was divided into five types,is 'extreme drought','severe drought', 'middle-degree drought', 'less severe-degree drought' and 'slight drought' regions,according to the frequency and intensity. The study showed that one reason for the soil drought was the insufficient rainfall and the other was unreasonable use of the rainfall . The key to the relaxation of spring soil drought lies in storing up the rainwater to the maximum,reducing the loss of rainwater to the minimum,and cultivating the robust seedling by a set of cultivating measures .
