摘要

[目的] 探索影响毛乌素沙地人工培育苔藓结皮的关键因子及其最优组合

为该区土地荒漠化的治理提供理论支持。[方法] 利用正交试验设计方法

考虑遮阳、覆膜、营养液、浇水频率4个因子

分析不同因子对苔藓结皮株密度和生物量的影响。[结果](1) 除Knop营养液外

遮阳、覆膜、浇水频率对苔藓结皮株密度、生物量有显著影响。(2) 遮阳、覆膜、营养液、浇水频率4个因素对不同指标的影响顺序不同。(3) 就株密度而言

野外培养最优条件为遮阳、不覆膜、Knop营养液和高频率浇水。就生物量而言

苔藓结皮野外培育最优因素组合为遮阳、覆膜、Knop营养液和高频率浇水。[结论](1) 在野外苔藓结皮培育过程中遮阳、覆膜、浇水频率对结皮生长都有显著影响。(2) 在提供适宜的生长条件的前提下

在干旱半干旱地区进行苔藓结皮人工培育是可行的。

Abstract

[Objective] The key factors affecting field artificial cultivation of moss dominated crust and their optimal combination were experimented to provide theoretical support for the desertification control in the Mu Us Sandland. [Methods] Based on an orthogonal experimental design with sunshade

film mulching

nutrient solution and watering frequency as controlling factors

plant density and moss biomass of dominated crusts were measured. [Results] (1) except of the Knop nutrient solution

sunshade

film mulching and watering frequency had significant effects on plant density and biomass. (2) Sunshade

watering frequency

film mulching

Knop nutrient solution had varied affecting order on different indicators. In terms of plant density

the best culturing conditions was: sunshade+without film mulching+nutrient solution+high frequency watering. In terms of biomass

the best culturing conditions was sunshade+film mulching+nutrient solution+high frequency watering. [Conclusion] (1) Sunshade

film mulching

watering frequency had significant impacts on the process of artificial cultivation of moss dominated crust. (2) Field artificial cultivation of moss dominated crust in arid and semi-arid regions is feasible on the premise of providing suitable growing conditions.
