据美国犹他州试验指出,移栽甜菜比直播甜菜增产10％,但是移栽甜菜能源消耗大,劳力费用多,美国农业部的报告认为,目前此法在美国仍不经济。日本移栽法延长生长期,提高生产量。为此遗传学家Theurer J.C.,Doney D.L.与美国农业部研究局在犹他洲洛根进行4年田间试验,移栽苗令为2—4周。他们看出,移 According to the Utah State Trial, transplanting beet yields 10% more than live beet, but transplanting beet has high energy consumption and labor cost. According to USDA’s report, this method is still not economical in the United States. Japanese transplant law to extend the growth period, increase production. For this reason, geneticists Theurer J.C., Doney D.L. and USDA Research Bureau conducted a four-year field trial in Island of Logan, Utah, with transplanted seedlings for 2-4 weeks. They see, move
