种植密度、施钾期及留叶数对烤烟上部叶质量的影响
Effects of Density, Period of Potassium Fertilization and the Number of Remaining Leaves on Quality of the Upper Part of Flue-cured Tobacco
摘要
Abstract
In order to find the effect of quality of the upper part of flue-cured tobacco leaves which limits main cultural measures in Yongsheng of Lijiang, for huge areas in a hot and dry river valley provides cultivation guidance. Processing the experiment that effects of density, period of potassium fertilization and the number of remaining leaves on quality of the upper part of flue-cured tobacco. The results showed that; in the condition of planting density was 1111 (120 cm×50 cm), K was 75 kg/hm with water solution at the time of removing membrane and covering soil and the number of remaining leaves was 20, the yield, output value, ratio of high grade, average price and net photosynthetic rate were the highest, reach 2351. 26 kg/ hm2, 30 448. 82 Yuan/ hm2, 48. 32% , 12. 95 Yuan/ kg, 14.72 mmol/ (m2·s).关键词
