几年来我们在甘薯示范片中的46000亩次的田块,搜集了潮薯一号的苗情观察记载资料,和经省、地、县、乡四级专家、科技人员测产验收189坵20多亩的田块资料分析,探索潮薯一号亩产5000公斤以上的高产栽培技术、苗情指标,为大田生产提供了科学依据。一、甘薯的生态指标与块根产量的关系1.甘薯块根与产量结构分析结果表明:潮薯一号单株结薯数多,插后20天块根形成;但薯块较小。田块考种结果看出:单株薯重变化大的对亩产影响也大,单株薯重、结薯数与亩株数有显著的负相关。在生产上应协调好亩株数、薯数、薯重的三者关系。
Over the past few years we have sweet potato potato plot of 46,000 acres of plots, collected the observation and record of the seedlings of the tide potato number one, and by the provincial, prefectural, county and township level four experts, scientific and technological personnel test 189 yield 20 Field plots of mu of information to explore the sweet potato yield of more than 5000 kg per mu of high-yielding cultivation techniques, seedling index for the field to provide a scientific basis for production. First, the relationship between the ecological indicators of sweet potato and tuber yield 1. The analysis of the tuberous root and yield structure of sweet potato showed that the tuber number of single plant per plant was more than that of tuberous root, but the tuberous root formed 20 days after inserted, but the tuber was smaller. Field test results showed that: a large single crop weight changes have a large impact on per mu, a single potato weight, tuber number and the number of acres had a significant negative correlation. In the production should coordinate the number of acres, the number of tubers, potato weight of the relationship between the three.
