The Study of Cutting Model of the Fiber Ramie Variety "Zhongzhu No.2" as the Forage
摘要
Abstract
Compared with the forage variety of ramie,the fiber varieties has distinct advantages of diversification of varieties,wide planting area and so on.Hence,it can promote and accelerate the application and extension of the project "fiber used as the forage"in the south with the research of fiber ramie ueds as the forage.In this paper,the fiber ramie variety "Zhongzhu No.2" was chosen as the research object,and the changes of growth performance,yield and forage quality of the ramie mowed at different height were throughly assessed to obtain the optimal cutting height for the fiber ramie.The results showed as follows:The growth rate of " Zhongzhu No.2" in vigorous growing stage was higher than that of in seedling stage with a trend of first increase and then decrease before September.The yield of dry matter and crude protein increased with the increase of the cutting height.Forage quality and leaf-steam ration decreased with the increase of cutting height.The optimum cutting height of "Zhongzhu No.2" in Changsha within a year were as follows:120 ～ 130 cm from March 6 to April 22;100 ～ 110 cm from April 23 to July 22;95 ～ 110 cm from July 22 to September 2;From September 3 to October 27,it can be harvested at 60 ～ 65 cm,and if the cutting time is advanced by more than 10 days,it can be harvested at 90 ～100 cm.关键词
