摘要
为优化木薯的矮壮素浸种增产技术,研究不同浓度的矮壮素溶液浸种6h和12h对木薯农艺性状、薯块产量与品质的影响.结果表明,与不浸种比较,200.00mg/L、300.00mg/L矮壮素浸种6h和100.00mg/L矮壮素浸种12h可显著矮化株高,0.00～100.00mg/L矮壮素浸种6h可显著增长薯长,300.00mg/L矮壮素浸种6h和200.00mg/L矮壮素浸种12h可显著增粗薯径;200.00mg/L矮壮素浸种6h可显著提高薯干可溶性糖含量,200.0mg/L、300.00mg/L矮壮素浸种6h可显著提高薯干淀粉含量.最优处理是300.00mg/L矮壮素浸种6h,可显著提高鲜薯产量41.7％、淀粉产量64.6％、收获指数10.5％;次优处理是100.00～200.00mg/L矮壮素浸种6h、12h,可显著增产鲜薯和淀粉并显著或明显提高收获指数.综合分析,推荐100.00～300.00mg/L矮壮素溶液浸种6h作为鲜薯和淀粉增产技术.
Abstract
In order to optimize the technology of increasing yield by soaking cassava cutting(SCC)in the solution of Chlorocholine Chloride(CC),the effects of the SCC for 6 h and 12 h by different concentrations of CC on the cassava agronomic traits,yield and quality of storage root(SR)were investigated.The results showed that,in comparison with non-soaking,200.00 mg/L,300.00 mg/L SCC for 6 h and 100.00 mg/L SCC for 12 h significantly dwarfed the plant height,0.00～100.00 mg/L SCC for 6 h significantly increased the length of SR,and 300.00 mg/L SCC for 6 h and 200.00 mg/L SCC for 12 h significantly increased the diameter of SR,200.00 mg/L SCC for 6 h significantly increased the soluble sugar content of dried SR,and 200.00 mg/L and 300.00 mg/L SCC for 6 h significantly increased the starch content of dried SR.The best treatment was 300.00 mg/L SCC for 6 h,and it significantly increased the fresh yield of SR by 41.7％,the starch yield by 64.6％and harvest index by 10.5％.The sub-optimum treatments were 100.00～200.00 mg/L SCC for 6 h and 12 h,which significantly increased the fresh yield of SR and starch yield,and also increased the harvest index.Based on comprehensive analysis,the technology of 100.00～300.00 mg/L SCC for 6 h was recommended to increase the fresh yield of SR and starch yield.
