:1999年乌盟地区4旗县(商都、兴和、后旗、凉城)1所(乌盟农科所)大面积利用梯度磁场处理马铃薯试验示范获得成功。其结果是 :在上述4县1所的731户农户、732hm2(其中处理408hm2 ,对照324hm2)的地块进行示范 ,平均每667m2 增产鲜薯161 1kg ,增产幅度为15 7 % ,与此同时分别对紫花白、底西瑞、乌盟851、中心24等4个主栽品种进行梯度磁场处理试验 ,增产幅度为8 0 %～11 9 %
: In 1999, a large area of 4 flag counties (Shangdu, Xinghe, Houqi, Liangcheng) in Wuhui Prefecture (Umeno Agricultural Science Institute) succeeded in experimenting with large-scale gradient magnetic field treatment of potatoes. As a result, a plot of 731 hm households in 1 county in 4 counties with 732 hm2 (of which 408 hm2 and 324 hm2) was processed showed an average increase of 161 1 kg per 667 m2 and a yield increase of 15 7% Gradient magnetic field treatment experiments were carried out on four main cultivars of purplish white flower, bottom west ridge, Ulleungnse 851, center 24, and the yield increase ranged from 80% to 11 9%
