草地研究和发展取得的成就 Aberystwyth学派提出的原则——即用频繁翻耕、播种栽培牧草品种的草田轮作,来改良草地——在第一次世界大战后的50多年内,在我国草地研究和发展中占主导地位。威尔士植物育种站的最大贡献乃是禾本科草的育种。根据具有相似生长习性的植物群落(直立型用于割草,匍匐型用于放牧)育成的草种,都比原利用品种多叶。他们从生长期短的牧草到多年生牧草,进行了一系列的育种工作。多年生 Achievements in Grassland Research and Development The Aberystwyth School’s principle of improving grasslands with grassland rotation with frequent tillage and sowing of forages of cultivated pastures has been demonstrated in grassland research and conservation in our country more than 50 years after the First World War Development dominates. The greatest contribution to the Welsh Plant Breeding Station is grass breeding. Grass species grown from plant communities with similar growth habits (upright for mowing, creeping for grazing) are more leafy than the original cultivars. From short-growing pastures to perennial grasses, they conducted a series of breeding efforts. perennial
