牧草利用次数和期限,是决定多年生牧草(包括苜蓿)生产率及获得饲料价值的主要因素之一。本研究旨在查明,在白俄罗斯东北部条件下,收割期及第一次和下一次刈割期对苜蓿生产年限的影响。试验于1976年在白俄罗斯农业科学院试验地上实施。试验地土壤为发育在轻壤土上的底层为壤质冰碛物的生草灰化土。腐殖质
The frequency and duration of pasture use is one of the major determinants of perennial pasture productivity (including alfalfa) and feed value. The purpose of this study was to determine the effects of the harvest period and the first and next mowing periods on the annual production of alfalfa in the northeast of Belarus. The test was carried out on the experimental site of the Belarusian Academy of Agricultural Sciences in 1976. The soil of the experimental site was grass-soaked asphaltic soil with loamy moraine developed on light-loam soil. humus
