泌阳县属浅山丘陵区 ,土壤质地粘重 ,透气性差 ,养分释放慢 ,有机质含量低 ,保水力差。其地理位置处在长江中下游麦区与黄淮平原麦区过渡地带 ,秋旱或秋涝发生频繁 ,加上灌溉条件差 ,因此小麦播种往往偏晚。土质粘重和播种晚成了影响当地小麦产量提高的主要限制因素。针对这点 Biyang County is a shallow hills, soil texture sticky, poor air permeability, slow release of nutrients, low organic matter content, poor water retention. Its geographical location in the middle and lower reaches of the Yangtze River and Huang-Huai Plain wheat area transition zone, autumn or autumn floods frequent, coupled with poor irrigation conditions, so the wheat planting is often late. Soil stickiness and seeding late became the main limiting factor affecting the increase of local wheat yield. For this point
