林甸县从1985年引进甜菜纸筒育苗技术，最初在我县宏伟乡立新村进行试验，当年获得平均每亩2．5t的产量。1986年在宏伟乡黄河村、1987年在四合乡会胜村连续两年做试验和示范推广，平均亩产都在3t以上，三年试验都获得了成功，由此增强了我们推广甜菜纸简育苗的信心。三年试验结 Lindian County introduced the technology of beet paper tube seedling cultivation in 1985, and initially experimented in Liuxian Xincun Village in our county, obtaining an average yield of 2.5 tons per mu in that year. In 1986, at Honghe Village, Hongwei Township, in 1987, it experimented and demonstrated for two consecutive years in Huisheng Village, Sihe Township. The average yield per mu was more than 3t. The three-year trial was successful, which enhanced our promotion of beet paper Jane seedling confidence. Three-year trial
