文成糯米山药施用无烟草木灰试验初报

Preliminary Report on the Application of Tobacco-Free Wood Ash in Wencheng Glutinous Rice Yam

摘要: 文成糯米山药是浙南山区当地农家薯蓣类品种，因糯米山药的生长特性，糯米山药需求一定量的有机钾肥。为探究糯米山药施用草木灰的效果，开展了草木灰在糯米山药育苗、移栽覆盖的试验。结果表明：糯米山药草木灰相较于常规育苗，草木灰育苗能有效促进芽体的生长与主根发育，优化根系结构，增加根系吸收能力，有利于糯米山药壮苗培育。草木灰覆盖对糯米山药以每株覆盖500 g草木灰较理想，能提升糯米山药产量。糯米山药施用草木灰对促进商品薯的商品性有优势，还可以提高糯米山药商品性和品质，具有良好的效益，为促进文成糯米山药产业可持续发展提供技术依据。

Abstract: Wencheng glutinous rice yam is a local yam variety in the southern mountainous areas of Zhejiang Province. Due to growth characteristics of glutinous rice yam, it requires a certain amount of organic potassium fertilizer. In order to explore the effect of applying charcoal ash on glutinous rice yam, trial of charcoal ash on seedling cultivation and transplanting covering of glutinous rice yam was carried out. The results showed that compared with conventional seedling cultivation, charcoal ash seed cultivation could effectively promote the growth of buds and the development of taproots, optimize the root system structure, increase the ability of roots to absorb nutrients, and be beneficial to the cultivation robust seedlings of glutinous rice yam. The coverage of charcoal ash on glutinous rice yam was ideal at 500 g per plant, which can improve the yield of glutinous rice yam. The application of charcoal ash on glutinous rice yam had an advantage in promoting the commodity of yam, and could also improve the commodity and of glutinous rice yam, which had good benefits, and provided a technical basis for promoting the sustainable development of Wencheng glutinous rice yam industry.
