种植密度和氮肥及其互作对邵阳烟区稻茬烤烟经济性状的影响
Effects of Planting Density,Nitrogen Levels and Its Interaction on Economic Character of Paddy-tobacco
摘要
Abstract
In order to explore the suitable planting density and nitrogen levels of paddy-tobacco,the effects of planting den-sity,nitrogen levels and its interaction on economic character of flue-cured tobacco were carried out by partial Eta2 val-ue. The results showed:1 )the effects of planting density,nitrogen levels and its interaction showed different influence on flue-cured tobacco economic characters. The effects of planting density on the fine tobacco ratio,average price and out-put value were significant higher;the effects of nitrogen levels on average price,yield and out-put value were significant higher;the interaction of planting density and nitrogen levels on the fine tobacco ratio,average price,yield and out-put value were significant higher. 2)the planting density,nitrogen levels and its interaction mainly affect average price of flue-cured tobac-co. 3)the effects of interaction on economic characters of flue-cured tobacco was the maximum (about 37%);nitrogen lev-els was the second (about 35%)and planting density was minimum (about 28%). 4 )the economic character of flue-cured tobacco was good at density 16 667 ~18 182 plants/hm2 and nitrogen 120~135 kg/hm2 applied in paddy-tobacco area in Shaoyang.关键词
