提高用种子繁殖产量的方法为了迅速扩大苧麻种植面积,近年我們提倡用种子繁殖。但苧麻天然杂交率高,用种子繁殖变异性很大,植株生长参差不齐,麻皮薄,产量和质量都較差。据我們几年来調查,用种子繁殖的麻地比用分蔸的产量低一成左右。怎样減少用种子繁殖低产的影 Methods to increase seed multiplication Yields In recent years we have advocated seed multiplication in order to rapidly expand the area under ramie cultivation. However, natural ramie high rate of hybridization, variability with the seed propagation is very large, uneven growth of plants, thin bark, yield and quality are poor. According to our investigations over the past few years, the yield of Maize grown by seeds is about 10% lower than that of Seeds. How to reduce the shadow of low yield with seed breeding
