野生木薯生物性状观察及嫁接生产技术研究
Observation on Wild Cassava Biological Characteristics and Grafting Technology
摘要
Abstract
[ Objective ] The aim was to study biological characteristics of wild cassava and explore grafting technology. [ Method ] Field sam-pling was carried out for observation ; different varieties were selected for grafting, the yield, starch content and yield were determined. [ Re-sult] The leaf area, leaf thickness, plant height, crown diameter, stem diameter of wild cassava were 308%, 137%, 186%, 177%, 165% higher than CK (SC205), which has a stronger growth potential. After grafting, the fresh cassava yield of different varieties were increased 14.9% - 109.3 % than CK, the difference was up to extremely significant level. The starch yield increased - 5.0% - 45.1%, the difference was not significant. Grafting or not (the same varietis), the fresh cassava yield increased 10.3 % -102.2%, starch yield increased -9.2% - 48.5%, while stach content obviously decrease, the decrease rate was - 9.8 % - 26.5 %. GR891 and GR5 are optimal grafting combina-tion, yield, starch yield, starch content all were higher than CK. [ Conclusion ] By grafting on wild cassava, the cassava yield increasing obvi-ously, which has great promotion value.关键词
