富盛公社,自1958年起曾大量开拓荒山隙地,馬鈴薯种植面积得到迅速扩大,并因讲究栽培技术,单位面积产量也得到迅速提高。与此同时,也发現馬鈴薯单位面积产量,存在着很不平衡的現象,特別是1960年春播夏收的馬鈴薯,低产的每亩只有700～800斤,高的則在4000斤以上。为了突破馬鈴薯平衡高产关,特进行了調查研究。初步明确本地区馬鈴薯产量的高低,固然与品种、施肥、密植、管理等都有密切关系,但是最主要的还是种薯問題。从調查中可以明显看出,利用夏薯(春播夏收)或秋薯(秋播秋收)做种,对植株生育及产量的影响,非常显著。 1.夏薯春播:据調查,利用夏薯春播,虽有出苗整齐、前期生長快、結薯早等优点,但茎稈較細,后期植株生長慢;至谷雨边薯皮开始老化,立夏
Fusheng commune, a large number of pioneers since 1958 to open up the desert land, potato acreage has been expanded rapidly, and due to pay attention to cultivation techniques, per unit area yield has also been rapidly increased. At the same time, it was also found that there was a very unbalanced yield per unit area of potato. Especially in the spring of 1960, potatoes were harvested in summer and the yield per mu was only 700-800 kg and the high was more than 4,000 kg. In order to break the potatoes high yield and balanced, special investigation. Preliminary clear the level of potato production in the region, of course, with varieties, fertilization, close planting, management and so on are closely related, but the most important is the seed potato problems. As can be clearly seen from the survey, the use of sweet potato (spring sowing summer harvest) or autumn (autumn sown autumn harvest) as a kind of plant growth and yield, very significant. 1. Summer potato sowing: According to the survey, the use of summer sowing spring, although the emergence of tidy, rapid growth early, early tubers and other advantages, but the smaller stems, late plant growth slow;
