摘要
以白及为试材,连续对不同生长年限白及生长旺盛期内(4—7月)的农艺性状和质量进行测量和比较分析。结果表明:4—7月,1年生白及各农艺性状均呈上升趋势,以根数增长较大,达93.34%,差异显著;花梗茎增长较小,为2.94%,差异性不显著。2年生白及各指标均有不同程度的增长,以最短根长增长幅度较大,达87.00%,差异显著;以最长根长增长幅度较小,为28.44%,差异性不显著;毛质量和块茎质量4—6月呈现上升趋势,到7月则有所下降。3年生白及块茎径、分叉茎总长、分叉茎总厚呈下降趋势,块茎厚、根数、最长根长、最短根长、毛质量及块茎质量呈上升趋势,以最短根长增长幅度较大,达187.12%,差异显著;以分叉茎总长下降幅度较大,达103.78%,差异显著。4年生白及除根数和根长呈现上升趋势外,其它各指标均呈现下降趋势,以分叉茎总厚下降幅度较大,达34.92%,差异性不显著;以最长根长增长幅度较大,达154.54%,差异显著。3年生白及含水量较高,1年生白及含水量较低;4年生白及胶含量最高,而2年生白及的白及胶含量较低。不同生长年限白及生长旺盛期的农艺性状与质量变化不同,研究结果为了解白及生长旺盛期的生长情况提供了参考。
Taking Bletilla striata as material,in order to measure and compare consecutively agronomic traits and quality of Bletilla striata of different growing years in vigorous growth period.The results showed that from April to July,various agronomic traits of 1-year-old Bletilla striata showed an upward trend,root number was larger and reached 93.34%,and the difference was significant;the stalk diameter was lesser and reached 2.94%,and the difference was not significant.The various indicators of 2-year-old Bletilla striata had different levels of growth,the shortest length of root growth was large and up to 87.00%,and the difference was significant;the longest root length was lesser up to 28.44%,and the difference was not significant;from April to June,gross weight showed an upward trend while declined in July.Tuber diameter,total length and diameter of fork stem of 3-year-old Bletilla striata showed a downward trend,tubers thick,root number,root length longest,shortest root length,gross weight and tuber showed an upward trend.The shortest root length was larger and up to 187.12%,and the difference was significant;the decline of total length of fork stem was larger and up to 103.78%,and the difference was significant.Except for the root number and root length of 4-year-old Bletilla striata,all other indicators showed a downward trend,decline of total diameter of fork stem was larger and reached 34.92%,and the difference was not significant;the longest root length was larger and reached 154.54%,the difference was significant.The water content of 3-year-old Bletilla striata was higher while 1-year-old Bletilla striata was lower,glue content of 4-year-old Bletilla striata was higher while and 2-year-old was lower.It was different of agronomic traits and quality,and the test results could be used as a reference to understand growth of Bletilla striata of different growing years in vigorous growth period.
