烤烟品种豫烟10号种植密度、施氮量和留叶数的优化研究
Optimization of Planting Density,Nitrogen Application Amount,Remained Leaf Number of Flue-cured Tobacco Variety Yuyan No. 10
摘要
Abstract
In order to provide quantity index to optimum cultivation measures of new flue-cured tobacco variety Yuyan No. 10, L9 ( 34 ) orthogonal experiments were set with three factors of planting density, nitrogen rate,remained leaf number and three levels,to study the effects of the three factors on the output value of tobacco. Single-factor analysis showed that the output value of tobacco increased with the increase of the planting density, first increased and then decreased with the increase of the nitrogen rate, and decreased steadily with the increase of remained leaf number. Two-factor interaction analysis indicated that the interaction between remained leaf number and nitrogen rate affected the output value most. The output value could reach 50217. 51 RMB/ha. The optimized cultivation indexes with the output value of Yuyan No. 10 more than 48500 RMB/ha were 18718—19495 plants/ha of planting density,47. 34—74. 75 kg/ha of nitrogen rate,19—23 pieces/plant of remained leaf number.关键词
