评价了不同种植密度对烟叶原料质量的影响。试验结果表明,生育期与不同的栽培密度关系不大;农艺综合性状以1100株/667m2处理最优;原烟外观质量以1100株/667m2处理的橘黄烟最多;经济性状以1100株/667m2处理最好,平均667m2产值达到2816.05元,分别比1000株/667m2处理区和1200株/667m2处理区增加100.88元和107.95元,产值增长幅度分别为3.58%和3.83%。本研究为烟叶合理密植提供了科学依据。
The effects of different planting densities on the quality of tobacco leaves were evaluated. The results showed that the growth period had little to do with the different planting densities; the comprehensive agronomic traits were the best with 1100 plants / 667m2; the appearance quality of the original tobacco with 1100 plants / 667m2 was the highest; the economic traits were 1100 plants / 667m2 The average value of 667m2 reached 2816.05 yuan, an increase of 100.88 yuan and 107.95 yuan respectively over 1000 plants / 667m2 and 1200 plants / 667m2. The output value increased by 3.58% and 3.83% respectively. This study provides a scientific basis for the close planting of tobacco leaves.
