云南省马铃薯饲用情况调查

Survey on Utilization of Potato as Feed in Yunnan Province

选择云南省大春马铃薯主产区昭通、曲靖、昆明的10个县市和冬小春马铃薯的3个主产县为样本,对2013年农户马铃薯的生产及饲用情况进行实地调查和分析。结果表明:大春马铃薯的饲用比例平均为32%,冬小春马铃薯的饲用比例平均为5%。基于调查结果推测,云南省马铃薯饲用的平均比例为26.7%,总量为320万t,占全省饲料总量的8.5%。发现在大春作区,马铃薯饲用比例较大,其中,饲用比例在30%以上的区域,主要在昭通市;饲用比例在10%至30%之间的区域,主要为曲靖、昆明的县市;饲用比例在10%以下的区域,主要是冬小春作区。

A survey on potato production and utilization as feed was carried out in ten spring potato producing counties in Zhaotong, Qujing and Kunming Cities and three winter and early-spring potato producing counties in Yunnan Province in 2013. The results indicated that an average 32%of spring potatoes and 5%of winter and early-spring potatoes were used as feed. It could therefore be calculated that nearly 26.7%of the total potatoes were used as feed, with a total amount of 3.2 mil ion tons making up 8.5%of total feed quantity in Yunnan Province. It was found that more than 30%of potatoes were used as feed in spring potato planting regions, especial y in Zhaotong City. 10%to 30%of potatoes were used as feed in Qujing City and Kunming City. In winter and early-spring potato planting regions, the average proportion was below 10%.
