摘要
为探索云南烟区雪茄原料烟叶合理的栽培密度和施肥量.采用"云雪1 号""云雪39 号"2 个品种,设置9 种栽培密度和施肥量,研究栽培密度和施肥量对雪茄烟叶农艺性状和经济性状的影响.试验结果表明,中等偏低的栽培密度可以获得更优的茎围、最大叶长、最大叶宽,而株高则与之相反.在一定范围内,提高施肥量可以提高烟叶的经济性状.在施肥量相同的条件下,产量和产值均随栽培密度的减少而降低,而上等烟比例则升高.茄衣品种"云雪1 号"栽培密度行距110 cm,株距35 cm,平均种植2.59 株/m2,施肥量为施纯氮15 g/m2 的经济性状更佳.茄芯品种"云雪39 号"栽培密度行距110 cm,株距45 cm,平均种植2.00 株/m2,施肥量为施纯氮21 g/m2 的栽培密度和施肥量的经济性状更佳.确定了"云雪1 号"和"云雪39 号"2 个品种的适宜栽培密度和施肥量,对以后品种的推广和雪茄烟叶的生产都具有借鉴意义.
Abstract
In order to explore the reasonable cultivation density and fertilizer amount of cigar leaf in Yunnan tobacco area. Two varieties,"Yunxue No. 1" and "Yunxue No. 39",were used to set 9 kinds of cultivation density and fertilizer amount to study the effects of cultivation density and fertilizer amount on agronomic and economic characters of cigar tobacco. The results showed that the stem circumference,maximum leaf length and maximum leaf width were better with medium and lower cultivation density,while the plant height was opposite. In a certain range,increasing nitrogen application rate can improve the economic properties of tobacco leaves. Under the same nitrogen application rate,the yield and output value decreased with the decrease of cultivation density,while the proportion of fine tobacco increased. The planting density of "Yunxue No. 1" is 110 cm,the plant spacing is 35 cm,the average planting is 2. 59 plants/m2,and the economic characteristics are better when the fertilizer amount is 15 g/m2 . The planting density of the eggplant core variety "Yunxue 39" is 110 cm,the plant spacing is 45 cm,and the average planting density is 2. 00 plants/m2,and the planting density and fertilizer amount of pure nitrogen 21 g/m2 are better. This study determined the appropriate cultivation density and fertilizer amount of "Yunxue No. 1" and "Yunxue No. 39" varieties,which is of reference significance for the promotion of varieties and the production of cigar tobacco leaves.
