为改变我市春马铃薯收获迟、产量低和效益差的生产状况,我们于1987年在下宅乡前山村吴治洪等三户对春马铃薯进行了异地引种、催芽、施肥、种植方式和地膜覆盖等五个方面的改进。2.62亩试验田1月19日下种,5月4日收获,平均亩产1184.26公斤,比新品种、平法栽培的增产442.18公斤,增长59.6％;比老品种、老栽培法增产939.89公斤,增长3.85倍。“五改”栽培技术的主要优点是早熟、高产、高效益,收获期由常规的5月底到6月初提早到4月底到5月初,早收20～30天,有利全年三熟制的安排和缓和5月份蔬菜春淡的供需矛盾,因此深受农户欢迎。1988年全市马铃薯“五改”面积发
In order to change the production situation of late spring potato harvest, low yield and poor efficiency in our city, we conducted the introduction, germination, fertilization, planting methods and plastic film mulching on spring potatoes in three places such as Wu Zhihong and Qianzhi Village, Xiazhai Township in 1987 Improvements in all aspects. The experimental field of 2.62 mu was planted on January 19 and harvested on May 4, with an average yield of 1184.26 kg per mu, an increase of 442.18 kg or 59.6% over that of the new cultivars. The increase was 59.6% 3.85 times. The main advantage of the “five changes” cultivation technology is early maturity, high yield, high efficiency, harvest period from the regular end of May to early June early to the end of April to early May, early harvest 20 to 30 days, And ease the spring vegetable supply and demand in May conflict, so welcomed by farmers. In 1988 the city’s potato “five changes” area hair
