摘要
Abstract
The trial studied biological characteristics and quality of alfalfa with different irrigation a-mount. The result showed the percentage of accumulated of dry matter was the highest in flowering stage at second stubble. There was a significant difference about stem-leaf ratio of growth period under different treatment. Positive correlation was seen between crude protein, crude fat and ash with water amount, negative correlation about crude fiber, acid detergent fiber. Nitrogen-free extract was influenced at initial flowering stage under different treatment, no any influence with crude ash. The best harvest time was at squaring period and 60 %~65% of field capacity to get the best quality and highest biomass.关键词
