摘 要: | 为筛选出适应陇县烟草种植的适宜密度,优化陇县烤烟品种布局并提高烟草产量与质量,通过小区对比试验,对烤烟品种秦烟99适宜栽植密度进行了研究,并对其农艺性状、抗病性、主要经济性状、原烟外观质量进行了评价。结果表明,随着栽培密度的增加,秦烟99大田生育期延长,株高、腰叶减小,发病率增加,经济效益变差,烤烟产量与栽植密度成正相关关系。陇县烟区秦烟99的栽植密度以1.50万株/hm2较为适宜,在该栽培密度条件下,烟叶产量达1 806.0 kg/hm2,产值达到50 433.0元/hm2。

Abstract: | [ Objective ] To screen the appropriate density for tobacco planting, optimize the layout of flue-cured tobacco varieties in Longxian Region and improve tobacco production and quality[ Method ]The disease resistance, botany traits, agronomic characters and economic characters of Qinyan 99 was studied through the comparative test of the community. [ Result ] With the increase of planting density, the growth period of the field is prolonged, the plant height and waist size of flue-cured tobacco decrease, the incidence rate increases, and the economic benefit becomes worse. The yield and density of flue-cured tobacco are positively correlated. [ Conclusion ]The planting density of the tobacco area in Longxian Region is more suitable for 1.5×104 plants/hm2. At this density, the yield of tobacco leaves per hectares is 1806 kg, and the output value reaches 50433 yuan. |
