鄱阳湖湖滩草洲发展畜牧业的试验研究

鄱阳湖是一个过水型湖泊,洪水季节,茫茫一片.枯水季节洲滩显露后,湿生草本植物相继萌生,是天然的季节性牧场.本文就鄱阳湖水位变化与洲滩显露淹没规律,植物的生物量,营养成分和自然载畜量,草洲利用现状,提出合理利用鄱阳湖湖滩草洲发展畜牧业的意见,并建议对现有畜禽品种进行改良和建立一个以水禽为主休的草洲畜牧业体系.同时,还应正确处理牧业与其他各业的关系,以及充分发挥草洲的效益.

STUDIES ON THE DEVELOPMENT OF DOMESTIC ANIMALS IN THE POYANG LAKE'S MEADOWS

The Poyang Lake is a seasonal impounding and releasing lake, of which, the water level between flood and dry season varies greatly every year (about 7-10 m in general). In the flood season, water rises and cover a broad area and many meadows are submerged. But in the dry season, flood recedes and the covered meadows appear again. At that time,lush meadow vegetation grows rapidly and the meadows become natural grazing land. This paper, based on the predecessor's works and the materials from the field survey and laboratory analysis from 1984 to 1986 by the authors, considered the main vegetation's biomass, content of nutritious substance, grazing capacity and grazing season some proposals were given for utilizing the meadows for livestock in grazing season.
