泡沫酸脱绒、精选,包衣等是棉种加工生产标准化、成品化、包装化的一项新技术,经加工处理的棉种质量显著提高,防虫防病效果明显,出苗快而整齐,棉苗素质好,有利于培育壮苗,增产增收,提高植棉经济效益。但在加工过程中,棉种经脱绒后残酸率的高低直接影响到种子的生活力,贮存期及幼苗的生长发育。为此,我们对泡沫酸脱绒残酸率对种子质量的影响进行了试验研究。材料和方法通过调整泡沫酸与棉种比及氨中和时间,并对所产脱绒棉种进行 pH 值和酸含量测定,以酸的残留率为0、0.01%、0.03%、0.05%、0.08%、0.10%、0.12%、0.15%、0.20%、0.25%、0.30%的棉种为材料。各材料分别取200粒用湿沙平皿法进行室内发芽率和发芽势测定;各取1公斤贮存6个月,每个月测定一次发 Foam acid depilation, selection, coating and so on are cotton processing standardization, production, packaging of a new technology, the quality of the treated cotton significantly improved, pest control and disease prevention effect is obvious, quick and neat emergence, Cotton seedlings of good quality, is conducive to nurturing strong seedlings, increase production and income, improve cotton economic benefits. However, during the processing, the rate of residual acidity of cottonseed directly affects seed viability, storage period and seedling growth and development. For this reason, we conducted an experimental study on the effect of foam acid acid removal rate on seed quality. MATERIALS AND METHODS By adjusting the ratio of foam acid to cotton and the time of ammonia neutralization, the pH value and the acid content of the degenerated cotton seeds were determined. The residual acidity was 0, 0.01%, 0.03%, 0.05% 0.08%, 0.10%, 0.12%, 0.15%, 0.20%, 0.25%, 0.30% of cotton seed material. The materials were taken 200 with wet sand plate method indoor germination rate and germination potential; each take 1 kg of storage for 6 months, measured once a month
