株行距、留叶数对烤烟品种KRK26主要经济性状的影响
Effects of Planting Spacing and Leaf Number on Main Economic Characters of Flue-cured Tobacco KRK26
摘要
Abstract
In order to find out the suitable cultivation practices for KRK26,the flue-cured tobacco cultivar introduced from Zimbabwe,in Yichang,Hubei Province,the effects of row spacing,plant spacing and the number of leaves after topping on yield and main economic characters of the flue-cured tobacco variety KRK26 were studied with L9(34)orthogonal experiments.The results showed that row spacing had a highly significant impact on average price and the percentage of above-average grading leaves.Plant spacing had a highly significant impact on yield,output,proportion of high class leaves and above-average grading leaf percentage,and had a significant impact on the proportion of upper leaves.Leaf number had a highly significant impact on output.The appropriate cultivation measures of KRK26 include 120 cm of row spacing,55 cm of plant spacing and 21-23 leaves in Yichang city of Hubei Province.关键词
