对3种三叶草不同生长期营养物质含量的动态变化进行初步研究,并以粗蛋白为标准对其营养均衡价作对比.结果表明,不同三叶草组织中粗蛋白、中性洗涤纤维、P和Ca含量都随着生长期的推移呈先下降后上升趋势.其中中性洗涤纤维和Ca的含量在结实后期(10月)最高;粗蛋白和P含量在生长初期(5月)最高;在盛花期(7月)最低.粗灰分含量随着生长期的推移而呈现不同的变化规律.野生型红三叶和普通红三叶的粗灰分含量先降低后升高,瑞文德的粗灰分含量则是随着生长期的推移而一直下降,3种三叶草的粗灰分含量在生长初期(5月)最高;酸性洗涤纤维的含量则随着生长时期的推移呈现上升的趋势.3种三叶草营养均衡价(NB)依次为:瑞文德>野生型红三叶>普通红三叶.

The nutrient status and dynamics of three clover (Trifolium spp.) varieties at different growth stages were investigated with the crude protein content as an indicator of nutrient equilibrium. The crude protein, neutral detergent fiber (NDF), phosphorus (P), and calcium (Ca) content of three clover varieties followed a decreasing trend at the initial growing stage and increased later on. The neutral detergent fiber and Ca content peaked in May, while crude protein and P content reached the highest in May and the lowest in July. The crude ash content followed an uncertain pattern as plant grew. The ash content of both wild-type red clover (T. pratensis L.) and the common red clover decreased at the beginning and then decreased. However, the ash content of 'Revendel' white clover (T. repens L.) decreased all through the experimental period. The general trend was observed for all three clover varieties as the ash content was the highest in vegetative growing stage (May), and the acidic detergent fiber (ADF) content increased with time. The nutrient equilibrium value was ranked as 'Revendel' white clover>wild-type red clover>common red clover.
