甜菜为我国北方主要糖料作物之一,为了保证全苗、增加生育期,提高单位面积产量,我场进行了甜菜温床纸筒育苗移栽试验,据田间观测,经过温床纸筒育苗的,比大田直播的一般成苗率高、苗壮、苗齐、块根较大。经我们小区对比试验,纸筒育苗0.32亩地收获5334.3斤,对照0.5亩收获3356斤,纸筒育苗可增产58.9％。甜菜温床纸筒育苗,我们是用代牛皮纸,作成高14厘米,口径10厘米的纸筒,内装培养土(为砂壤土、内加1％过磷酸钙,拌匀捣细,过筛后装入)捣实至三分之二处,置于温床,以便播种。
Beet is one of the main sugar crops in northern China. In order to ensure the whole plant, increase the growth period and increase the yield per unit area, we conducted the transplanting test of paper tube seedling in the beet seedbed. According to the field observation, Ota broadcast the general high rate of seedlings, Miao Zhuang, Miao Qi, larger roots. After our plot comparative test, paper tube seedling 0.32 acres of land to harvest 5334.3 pounds, control 0.5 acres harvest 3356 pounds, paper tube seedling can increase 58.9%. We use kraft paper to make a paper tube with a height of 14 cm and a caliber of 10 cm. The paper contains culture soil (sandy loam, 1% superphosphate, ) Tamp to two thirds and place on a hotbed for sowing.
