文档介绍：不同移栽方式对烤烟生长发育、产量及品质的影响
摘要:该文以粤烟97为材料,通过大田试验,研究了人工打穴移栽、机械打一穴移栽、机械打两穴移栽3种移栽方式对烤烟生长及产质量的影响。结果表明,机械打穴的移栽方式能够提高烤烟成活率,促进烤烟生长发育,提高烤烟的产质量,且以机械打两穴移栽方式产量及产值最高,同时其烤烟的化学成分最为协调。总而言之,机械打两穴移栽方式为清远地区较为适宜的移栽方式。

Abstract:Taking YueYan 97 as material and through field tests, the effects of 3 methods of transplanting such as artificial transplanting, mechanical transplanting and mechanical transplanting two points on growth and yield and quality of flue-cured o were analyzed. The result showed that, the method of mechanical transplan
ting can improve the survival rate, the yield and quality of flue-cured o, and the highest yield and output value was by mechanical transplanting two point. At the same time, the position of flue-cured o was the most harmonious. In general, the method of transplanting the two points of the machine is more suitable for transplanting.

烤烟的生长发育会受到基因型、生态环境及栽培措施等多方面的影响[1]。移栽是烤烟生长过程中重要的栽培措施,科学的移栽方式有利于优质烤烟的生产,能够减轻烤烟生产前期低温冻害以及生产后期高温逼熟对烤烟品质的影响[2]。近年来,针对烤烟的移栽方式进行了许多研究[3-7],不同移栽方式对烤烟生长发育的影响显著。研究表明,大壮苗深栽结合一次性双层施肥技术有利于提高烤烟生长前期根系活力,促进烤烟生长[8-9]。小苗膜下移栽可以提高烤烟前期生长温度,避开蚜虫迁飞高峰,减少病毒病的危害[10],同时烤烟根系、单叶重及叶片数等明显提高[11]。刘杰
