摘要
10年定位研究表明,天然草地地上生物量受气象条件所制约,降水起主导作用。羊草草地和贝加尔针茅草地均属氮碳营养类型,适宜发展毛肉兼用型细毛绵羊和乳肉用家畜。青草在7~8月营养丰富,产草量高,是打草贮存的最佳时期。
. A ten-year in site research indicated that precipitation is the most important environmental factor governing the produetivity of the natural grasslands. Leymus Chinensis grassland and Stipa baicalensis grassland belong to C-N nutrition grassland type, being suitable for the development of wool-meat or dairy-meat dual purpose animal husbandry. July to August is considered the bast time for hay making activity, when the forage reaches the highest yield with a fairly good quality.
