纸筒育苗移栽甜菜能大幅度提高产量,这已在日本甜菜生产实践中得以证实。日本在战前每公顷甜菜产量仅有10余吨,1965年以前亦只限于25吨左右,自1956年增田昭芳博士开始研究“纸筒育苗移栽法”起,由于其增产幅度可达20—30％,便很快运用于生产,至1965年纸筒育苗移栽面积达甜菜总种植面积的20％左右,十年后的1975年达80％左右,这时日本甜菜产量提高到45—50吨/公顷。到1981年,移栽面积己达日本甜菜总面积的93.5％,平均公顷产量达58.5吨。日本在15年内,甜菜单产增加一倍以上,除运用高产杂优品种、有效地防治病虫害和提高施肥水平外,采用纸筒育苗移栽技术是其增产的主要原因。 Paper tube seedling transplanting sugar beet can greatly improve the yield, which has been confirmed in Japanese sugar beet production practice. Before the war Japan beet yield per hectare only 10 tons, before 1965 was limited to about 25 tons, since 1956 Dr. Zhaofang started studying “paper tube seedling transplanting method”, due to its increase rate of up to 20 -30%, it is quickly applied to the production, to 1965, the transplanting area of ​​paper tube seedlings reached about 20% of the total area planted beet, about 10% after 1975 reached 80%, then the Japanese beet yield increased to 45- 50 tons / hectare. By 1981, the transplanted area had reached 93.5% of the total beet area in Japan with an average yield of 58.5 tons. In 15 years, Japan’s sugarbeet yield more than doubled. In addition to using high-yielding hybrid varieties, effectively preventing and curing pests and diseases and increasing fertilization levels, the main reason for its increased yield was the use of paper tube seedling transplanting.
