摘要
随着水稻种植面积的连年增加,地下水位急剧下降,水稻种植区有限的水资源已无法承受水稻面积的持续增加。国家通过统筹规划政策调控减少水稻面积,合理利用有限水资源,实行部分水改旱。玉米是C4作物,具有产量和商品性高等特点,近年来,随着玉米价格再创新高,种植玉米效益持续增加,水稻田改种玉米更符合种植者效益。该研究针对稻田改种玉米后的常见问题,提出水改旱玉米栽培要点和措施。
With the continuous increase of rice planting area,the groundwater level droped sharply,and the limited water resources in rice planting area could not bear the continuous increase of rice area.Our country had reduced rice area through overall planning policies,rationally utilized limited water resources,and implemented partial water conversion to drought.Corn was a C4 crop with high yield and commercial characteristics.In recent years,as the price of corn has reached a new high and the benefit of planting corn had continued to increase,it was more in line with the benefit of growers to plant corn in paddy fields.In view of the common problems after maize conversion in paddy fields,this study put forward the key points and measures of maize cultivation after water conversion to drought.
