黄淮海地区是我国红麻的主要产区,自然气候条件好,增产潜力大。近年来,该区播种面积占全国黄、红麻面积的一半以上。但该区有70％以上为麦茬麻,由于播种迟、生长天数不足,兼之采用的品种和栽培管理不当,纤维产量低,成了我国黄红麻的低产区。1982—1986年围绕提高麦茬麻单产这个中心任务,进行了调查研究、试验研究和大面积示范,取得了明显的增产效果和经济效益。1984年小面积高产田平均亩产纤维273公斤,8.3万亩大面积高产示范田平均亩产纤维达176.5公斤,比试验前三年平均亩产提高近50 Huang-Huai-Hai region is China’s kenaf of the main producing areas, good natural climatic conditions, yield potential. In recent years, sown area in the area has accounted for more than half of the country’s yellow and kenaf area. However, more than 70% of this area is wheat stubble. Due to late planting and lack of growth days, the varieties and cultivation management adopted in the area are not good, and the fiber yield is low, making it a low-yield area in China. From 1982 to 1986, the central task of improving the yield of wheat stubble was conducted, and the investigation, experimental research and large-scale demonstration were carried out. Significant stimulation and economic benefits were achieved. In 1984, an average of 273 kilos of mu per mu of fiber and an average of 176.5 kilos of mu of fiber per mu of 8.3 million mu of large-scale high-yielding demonstration plots were found in the small-yield high-yield fields, an increase of nearly 50%
