Effect of Stereo FIoating Breeding on FIue -cured Tobacco SeedIing QuaIity and SeedIing Cost
摘要
Abstract
In order to study the difference between stereo floating breeding and conventional floating breeding of flue -cured tobacco,experiment with different warming measures was carried out,the effect to seedling emergence rate,seedling quality and benefit were compared.The result showed that the seedling emergence rate,seedling establishment rate,the root cap ratio and root volume of warming nursery pond were 0.50% ~2.50%,1.00% ~3.50%,0.01 ~0.02 and 4.60 ~9.30 mL higher than that of non -warming nursery pond respectively.The above indexes in the superior stratum of the warming greenhouse were 2.00%,2.50%,0.01 and 4.70 mL higher than that in the sub -stratum.Warming nursery pro-moted seedling growth,but average cost of each plate is 1.24 yuan higher than that of un -warming nursery.关键词
