一、基本情况马铃薯是内蒙古乌盟大宗的优势作物,每年播种面积均在200万亩左右。由于马铃薯抗旱高产、适应性强,无论丰年、欠年,在乌盟粮食生产中都占总产量的百分之二十至百分之四十。起着其他作物无法替代的作用。但是,因为马铃薯的退化,亩产仅371.8公斤远远低于全国686公斤及全世界912公斤的水平。因此,解决马铃薯的退化,不断探索马铃薯的增产途径,始终是推进乌盟农业生产发展的重要课题之一。马铃薯低产是因退化,造成马
First, the basic situation Potato is the bulk of Um, Inner Mongolia, the dominant crop, sown area of 200 million mu each year. Due to the drought-resistant potato with high yield and adaptability, both the harvest and the year of the year have accounted for 20% to 40% of the total output of the UMNO food production. Play the role of other crops can not be replaced. However, because of the deterioration of the potato, only 371.8 kg per mu is far below the national level of 686 kg and the world’s 912 kg. Therefore, to solve the degradation of potato and explore ways to increase yield of potato is always one of the important topics for promoting the development of agricultural production in UZU. Low yield of potato is due to degradation, resulting in horses
