彭县白鹿乡所产马铃薯,灌县、郫县、温江、双流、什邡、新都、新繁、新津、崇宁、金堂、大邑、邛崃、华阳、广汉、成都、绵阳等十七县市以及彭县坝地乡镇农民每年冬腊之际,均前往购买,用作种薯。但是项种薯如在上述地区栽种一年(有时二年)以后,不加更新,则表现严重的退化现象。马铃薯植株生长孱弱,地上部表现徒长,叶茎扭曲,有毒素病病徵表现,块茎变小,产量降低。甚至不能收回播种时所用的块茎重量。因此,这种产量很高的粮食作物,在不断提高单位面积产量方面于扩大栽培面积方面,都受到一定限制。作者等为了解彭县白鹿乡马铃薯种薯生产区品种情况,耕作栽培情况以及种薯繁育情况作为进一步研究提高马铃薯单位面积产量的农业技术措施和防止马铃薯在川西平原地区退化的方
Pangxian Bailu Township Produced potato, irrigation county, Shexian County, Wenjiang, Shuangliu, Shifang, Xindu, Xinfan, Xinjin, Chongning, Jintang, Dayi, 邛 崃, Huayang, Guanghan, Chengdu, Mianyang and other seventeen The counties and cities and towns and villages in Pengxian County goverment purchase winter seedlings for their winter seed. However, if the seed potatoes were planted for one year (sometimes two years) in the above-mentioned areas, they would be seriously degraded if they were not renewed. The growth of potato plants was weak, the shoots showed leggy stems, the stems were distorted and the signs of toxic diseases were found. The tubers became smaller and the yield decreased. Can not even recover the weight of tubers used in sowing. As a result, such high-yielding food crops are subject to certain restrictions in expanding the area under cultivation in order to continuously increase yields per unit area. In order to understand the variety of potato seed-producing area, cultivation and cultivation of seedling and breeding of seed potato in Bailu Township of Peng County, the author studied the agricultural technical measures to further increase the yield per unit area of potato and the measures to prevent the potato from degenerating in the plain of western Sichuan
