日本对草地施肥和牧草营养生理的研究是从1955年正式开始的,其历史较短。因此,对草地的施肥可以说是基于从水稻上得到的营养生理知识。直到最近才明确了禾本科牧草的产量构成要素分蘖的多少和施肥的关系。但是牧草营养分吸收和产量构成要素的分蘖数及单茎重的关系还不太清楚。本研究用日本主要禾本科牧草之一的猫尾草,研
Japan’s research on grassland fertilization and pasturage nutrition and physiology was formally started in 1955 with a short history. Therefore, the fertilization of grassland can be said to be based on the nutritional physiology obtained from rice. It has only recently been clarified how much tillering is responsible for the yield component of gramineous pasture and its relationship to fertilization. However, the relationship between the number of tillers and single stem weight of forage nutrient absorption and yield components is not yet clear. In this study, one of the major grasses in Japan, Timothy grass, research
