发展秋马铃薯生产,是防止马铃薯退化,增加粮食产量的一项重要措施。但秋马铃薯生产往往受着前期高温干旱、后期霜冻死苗的影响,一般亩产只有1,000斤左右,而且不稳定。为此,1976年,南方片第一次马铃薯科研生产协作会议确定开展秋马铃薯高产稳产栽培技术的研究。经过协作组两年来的共同努力,基本上掌握了高产稳产的关键技术措施,有的突破了亩产3,000斤。如华中农学院宜昌分院,1973年秋马铃薯亩产1,000斤,1977年提高到3,000斤。湖南省新晃县中寨公社沟溪大队,1977年秋马铃薯185亩,平均亩产1,765斤,其中有两亩亩产3,150斤。通过近年来的小面积试验和大面积生产实践,我 Developing autumn potato production is an important measure to prevent potato degradation and increase grain output. However, the production of autumn potato is often affected by the high temperature and drought in the early stage and the dead frost in the late stage. Generally, the yield per mu is only about 1,000 kg and is unstable. To this end, in 1976, the first cooperation in southern flake potato production research collaboration to determine the high yield and stability of autumn potato cultivation techniques. After concerted efforts by the cooperation team over the past two years, they have basically mastered the key technical measures of high and stable output, some of them have exceeded 3,000 kg of mu per mu. For example, Yichang Branch of Huazhong Agricultural College had a yield of 1,000 kg per mu in autumn 1973 and an increase of 3,000 kg in 1977. Shouxi Brigade, Zhongzhai commune, Xinhuang County, Hunan Province, 185 acres of autumn potato in 1977, with an average yield of 1,765 kg per mu, of which 3,150 kg per mu. Through the small area test in recent years and large-scale production practice, I
