Effect of Urea Combined with Ca(OH)2 on Fiber Yield and Quality of Ramie Xiangzhu 3
A field experiment was carried out to study the effect of urea combined with Ca(OH)2 on the fiber yield and quality of ramie(Boehmeria nivea) variety Xiangzhu3. The results showed that, in the range of 150 ~ 450 kg/hm2 of urea application level, the fiber fineness, single fiber strength, pectin content and residual pectin rate had significant positive correlation with the increase of Ca (OH)2, and the fiber yield had no significant correlation with Ca(0H)2. The fiber yield increased most significantly with the suitable combination of urea and Ca (0H)2. The suitable combination was urea 300kg and Ca (OH)2 375kg/hm2. Reasonable use of urea combined with Ca(OH)2 could play a very important role in guiding fertilization and enriching the nutrition theory of ramie planting, as well as further improving the fiber quality of ramie.
