摘 要:为探索烟草免地膜漏斗式移栽适宜的施肥方法,特进行了移栽后不同天数基肥条施、穴施的大田试验,分析不同处理对烤烟农艺性状、干物质积累、经济性状以及内在化学成分指标的影响。结果表明,处理3(基肥条施,移栽后35d追肥)烤烟的农艺性状综合表现好,干物质积累量多,内在化学成分协调性好,且产值、上等烟比例和均价最高,分别达52120.5元/hm2、47.5%、21.04元/kg。

Abstract: In order to explore the suitable fertilization method of funnel transplanting without plastic film, field experiments were carried out with strip application of basal fertilizer and hole application of basal fertilizer in different days after transplanting, analyzed their agronomic characters, dry matter accumulation, economic characters and internal chemical composition indexes. The results showed that treatment 3 (strip application of basal fertilizer and top dressing 35 days after transplanting) had good comprehensive performance of agronomic characters, more dry matter accumulation, good internal chemical composition coordination. And the proportion of superior tobacco and the average price were the highest, which were 52120.5 yuan/hm2, 47.5% and 21.04 yuan/kg, respectively.

在煙草生长发育过程中,肥料的施用方式直接决定着肥料的利用和烟株的生长发育,因地制宜进行施肥才能发挥出肥料的最大利用效率,实现烟叶产质量的最佳[1]。目前,对于基肥施用方式和时间已有相关大量的报道,合理的施用方式和施用时间能够提高肥料利用率[2-5]。为此,本研究在贵州毕节金沙科技园采用漏斗式移栽方式替代地膜覆盖技术,探索基肥适宜的施用方法,为免地膜漏斗式移栽肥料应用提供科学依据。

1 材料与方法

1.1 供试材料 供试品种为云烟87。

1.2 试验设计 本试验在贵州毕节金沙科技园进行,采用小区对比试验,5个处理,3次重复,随机区组排列。周围设保护行,行距1.1m,株距0.55m,每小区植烟70株。处理1:基肥条施,移栽后25d追肥;处理2:基肥穴施,移栽后25d追肥;处理3:基肥条施,移栽后35d追肥;处理4:基肥穴施,移栽后35d追肥;处理5:基肥条施,移栽后15d追肥。其他田间管理措施严格按优质烟栽培技术进行。……
