硫酸脱绒处理棉籽,是提高种籽质量的经济有效措施。经过处理后的种籽,一般健籽率、发芽率均可达90%以上,出苗率达80%左右,且病害减轻,成苗率提高。既有利于节约种子,培育壮苗,又可省去间苗定苗用工。硫酸脱绒成本低,一斤工业废浓硫酸只需一角多钱,可处理未剥绒的种子4～5斤,或剥过短绒的种子7～8斤,搞营养钵育苗移栽,足够一亩大田所需之用种。硫酸脱绒的方法也很简单,即将曝晒后的棉子放在缸内,按照使用比例将硫酸均匀倒在种子上,边倒边搅拌,待棉种短绒脱净,种壳发黑为止,约需10～15分钟(种子晒得越干,时间越短),然后在缸内倒入清水,并搅拌至棉子与棉绒分离,再用清水
Treatment of cottonseed with sulfuric acid is an economical and effective measure to improve the quality of the seeds. After treatment of the seeds, the general health-seed rate, germination rate of up to 90% or more, the emergence rate of 80% or so, and reduce disease, increased seedling rate. Not only help save seeds, nurturing strong seedlings, but also save the Miao Ding Miao labor. Sulfuric acid velvet low cost, a pound of industrial waste concentrated sulfuric acid just a dime more money, can handle unsplit cashmere seeds 4 to 5 pounds, or stripped fluffy seed 7 to 8 pounds, engaged in nutrition bowl seedling transplant enough Mu acres of land needed for the species. Sulfuric acid velvet method is also very simple, about to be exposed after the cotton in the cylinder, according to the use of sulfuric acid evenly poured on the seeds, while pouring edge stirring until the cotton seedling off net, the shell is black so far, About 10 to 15 minutes (the sun drying the seeds, the shorter the time), and then poured into the cylinder water, and stirred until cotton and lint separated, and then water
