毛乌素沙地生物结皮层藓类植物培育试验研究

摘要/Abstract

摘要： 通过对毛乌素沙地不同发育程度的藓结皮进行养分分析,根据其N、P、K含量,对Knop培养液进行修正,按照正交试验设计方法进行室内培育实验,研究最适合毛乌素沙地藓类植株茎叶碎段生长发育的温度、培养液浓度以及培养液使用量。结果表明,当温度为15 ℃,培养液为low Knop,加液体量为12 ml时,藓结皮的生长发育状况良好,其株密度为329株·皿-1,平均株高为4.5 mm; 25 ℃时处理间差异不显著,生长情况不及15 ℃,而35 ℃高温下没有茎叶碎段生长繁殖。根据所有处理株高随时间的变化,得出了藓类植株生长拟合曲线。本实验可为野外培育藓结皮尤其是毛乌素沙地生物结皮的人工修复提供了一定的参考。

Abstract: Based on the nutrient analysis of moss crusts of different growing stages in the Mu Us Sandy Land, the Knop culture medium was modified according to the contents of N, P, K of the moss crusts, and the moss crusts were cultivated in laboratory by the method of orthogonal experiment. The research aims to find the optimum temperature, culture medium content and its amount for the growth of moss plants' tatter leaf sections. The results indicated that the moss plants' density was 329 strains per dish, and the mean height was 4.5 mm in the conditions of 15 ℃, low Knop as the culture medium and 12 ml as medium amount; the growth in 25 ℃ was worse than that 15 ℃; and no growth in high temperature of 35 ℃. A height growth fitting curve of moss plants changing with time have been drawn in this research. The result can provide experimental basis for the field cultivation of moss crust, especially for the artificial recovery of biological soil crust in the Mu Us Sandy Land.
