种养平衡区域一体化与农业可持续发展——江苏省畜牧业增长与生态农业发展案例分析
8.Twelve lambs born spring of 2005 and weaned on May 5 and three 1.2 ha bermudagrass paddocks were used to evaluate the relationships between animal forage intake and forage canopy spectral absorbance over a nine week period, and also estimate heterosis, maternal breed effects and direct breed effects for forage intake,in order to optimize livestock production system of grazing sheep、keep balance of grassland-livestock and environment improvement.
本试验研究的目的是利用12只2005年春季出生,5月龄断奶的羔羊和3个百慕大草草场通过遥感技术来估测动物干物质采食量(DMI)与冠层光谱吸收率之间的关系,研究纯种羊和杂种羊采食量的差异、母体效应和育种效应,为优化放牧绵羊的生产体系和保持草畜平衡以及生态环境的改善提供理论依据。
9.Based on investigation and analysis of the feed, excreta, soil and waters of surface and underground in the livestock farms in Jiangsu Province with case region survey and nutrient analysis approaches, the nutrient cycling and management and environmental effect in intensive livestock production were assessed.
摘要运用案例区域调查法和养分物质分析法,对江苏牲畜养殖场饲料、牲畜排泄物、土壤、地表及地下水体养分状况进行了调查、分析,对牲畜规模养殖中的养分循环与管理及其环境效应进行了评价。
10.Eight key projects are brought forward for constructing evergreen grassland stockbreeding, they are: 1) leadoff enterprise and famous trademark cultivation project; 2) breed of forage grass, fine breed of livestock and poultry project; 3) grassland construction and forage planting project; 4) raw product base construction project; 5) prevention and cure of animal epidemic disease and service project; 6) livestock product security project; 7) science and technology, talent cultivation project; 8) network information project.
