引进津巴布韦烤烟品种KRK26在云南烟区最佳栽培措施筛选

KRK26是引自津巴布韦的烤烟新品种,其在云南烟区的栽培技术尚不成熟,以植烟密度、施肥量、留叶数和留叶方式4个关键生产技术为试验因素,设计4因素3水平的正交试验,以烟株的田间表现和产量产值为评价指标,对KRK26的最佳栽培措施进行筛选。结果表明,KRK26在云南烟区种植时,以株行距55 cm×120 cm、每公顷施氮量75～105 kg、留叶数22片、打顶时去掉下部2～4片叶为最优栽培技术组合。...

KRK26 was one of newly introduced flue-cured tobacco cultivars from Zimbabwe and its cultural measures in Yunnan tobacco growing area was not established.This study selected four key cultural measures（plant density,fertilizer application amount,available leaf number and way of topping） as experimental factors,and designed four factors-three level orthogonal test to evaluate KRK26＇s agronomical characteristics,leaf yield,leaf value,and optimized dits cultural measures.The results showed that the optimal cultural measures for KRK26 was the combination of line space 120 cm,row space 55 cm,75-105 kg N fertilizer/ha,22 available leaves and discarded 2-4 leaves in topping.
