多花黑麦草早期低刈的超补偿效应试验

研究多花黑麦草Lolium multiflorum受到胁迫时的反应机理,探讨了早期低刈对其分蘖、产量、品质的影响.结果表明,牧草早期低刈能促进其分蘖,增加产草量,提高牧草品质,具有超补偿效应;利用牧草的超补偿效应,在牧草栽培管理中通过人为因素限制地下根系的资源分配,使地上部分获得最大量的资源分配,从而达到增加牧草产量的目的.

The super compensate effect test for shortcutting of Flowery Blackwheat grass at early stage

To study the reactive mechanism when annual ryegrass is met coercion and probe into the impact on its tillering, yield and quality for cutting the grass at early stage is the core of this test. Short cutting of herbage at early stage could increase its tillering production and quality, which possesses super compensate effect. Therefore through man-made factors to limit the resource distribution of underground root system by using herbage super compensate effect could make the grass on the ground acquire maximum resource and reach the goal of raising grass production.
