河北坝上农牧交错带饲草供给与家畜需求分析

河北坝上地区是我国华北农牧交错区的主体部分,草原畜牧业是该区域的主导产业,针对该区域草地畜牧业所面临的生态和生产的问题,选取沽源、围场和丰宁3个典型县域草地为研究对象,采用野外调查测定和年鉴统计数据相结合的方法,从饲草供给与家畜需求的角度进行了比较分析。结果表明,3个县的草地产量与2012年农业部年鉴统计数据相一致,围场最高,其次是沽源,丰宁最低;饲草供给量与年鉴统计结果一致,且沽源县有机质、全氮、全磷含量在4个土层均显著高于丰宁和围场县,并根据各个县农业资源现状提出了沽源和丰宁2个县构建“粮-经-饲”三元种植结构模式、建立人工草地、开发新的饲料资源等方法解决饲草需求不足问题。

Analysis of Forage Supply and Livestock Demand in Bashang Area of Hebei Province

Bashang Area of Hebei Province is the main part of the agro-pastoral ecotone of North China, grassland livestock industry is the leading industry in the region. Aiming at the ecological and production issues, 3 counties （Guyuan, Weichang and Fengning） were selected as the research object, using the method combining field survey and statistical yearbook data, the comparative study was conducted from forage supply and livestock demand. The results showed that ： the yield of grass of 3 counties in Bashang region is consistent with the Ministry of Agriculture 2012 statistical yearbook, Weichang has the highest yield, followed by Guyuan, and Fengning has the lowest yield; forage supply statistical result is consistent with Yearbook, and the organic matter, total nitrogen, total phosphorus contents of Guyuan County in 4 soil layers are significantly higher than Fengning and Weichang County; and some solving methods were put forward according to the present situation of agricultural resources in various counties： construction of the ＂grain-by-feeding＂ planting model of Guyuan and Fengning, establishment of artificial grassland, development of new feed resources .
