沙芦草又名蒙古冰草,是盐池半荒漠草原地带分布较广的一种抗寒耐旱,萌发早,枯黄迟,且草质柔软,富含蛋白质、脂肪和多种矿质元素的多年生禾草。近年虽多次用来人工栽培或补播改良天然草场,但由于播种技术及自然条件等原因,出苗生长都存在一定问题。为了探索沙芦草在盐池自然条件下的适宜播种深度,为今后的推广种植提供依据,我们在1982年～83年进行了比较试验。现将试验结果报告如下。
Salix grass, also known as the Mongolian snow grass, Yanchi semi-desert grassland is widely distributed in a cold and drought, early germination, yellowish late, and the grass is soft, rich in protein, fat and a variety of perennial grain Wo grass. Although many times in recent years artificial cultivation or replanting to improve the natural grassland, but due to sowing technology and natural conditions and other reasons, there are some problems of emergence and growth. In order to explore the appropriate sowing depth of Salix psammophila under the natural conditions in Yanchi, and to provide the basis for the promotion of planting in the future, we conducted comparative experiments from 1982 to 1983. The test results are reported below.
