烤烟生产节水技术分析与初步研究

Preliminary Study on Water-saving Technique in Flue-cured Tobacco Production

摘要: 研究表明:碟形凹面移栽培土与地膜覆盖配套技术具有明显的聚水作用,能够将烤烟大田前中期有限的自然降水聚集于根际,提高了地膜覆盖栽培条件下降水的利用率,对烟株生长具有明显促进作用;采用隔行灌溉技术,既可满足烟株旺盛生长、成熟对水分的需求,又可避免灌后可能出现的涝渍对烟株根系的伤害。采用碟形凹面移栽培土与地膜覆盖配套技术和隔行灌溉技术达到了节水生产目的。

Abstract: Complementation of rkdge like a dish at setting and film covering could collect rainwater to rhizoSphere soil, increase rainwater utilization ratio, and stimulate significantly tobacco plant growth and development.Technique of irrigating every two line could meet the need of water for tobacco plant growht and development, avoidEd injuring root, was beneficial to saving water.
