去年,川沙县良种场和川沙县金桥公社金巷七队改变了常年的棉种粒选方法,用硫酸脱绒水选棉种,据一亩多田直播和河泥方格育苗试验,这种方法既可节省劳力,提高棉种质量,又能增加棉花产量,增产显著好处多。 1.壮苗早发,现蕾、结铃、吐絮早,产量高经过脱绒水选的棉种,千粒重提高了,棉籽壳表层的蜡质又被硫酸破坏,所以,透气性好,易吸水,出苗快,生长整齐,棉苗粗壮。据川沙县良种场试验,脱绒水选的棉种出苗比
Last year, Chuansha County seed market and Jinhanshaqiao Jinhansha commune Golden Alley team changed the perennial method of seed selection of cotton, cotton wool with sulfuric acid depulsed water, according to acres of direct seeding and riverbed nursery square seedling test, this method Can save labor, improve the quality of cotton, but also increase the cotton yield, yield significant benefits and more. 1. strong seedlings early hair, budding, boll, boll flow early, high yield through the cashmere water selection of cotton seed, 1000 grain weight increased, the cotton seed hull surface wax and sulfuric acid damage, so breathable, easy to absorb water Rapid emergence, growth and tidy, thick cotton seedlings. According to Chuansha County seed field test, velveteen selected cotton seedling emergence ratio
