选用比透明的聚乙烯薄膜更具有光温效应的银灰色地膜作覆盖材料,进行烤烟优化栽培技术模式研究,国内外极少报道。作者自1982年起,经6年深入研究和万亩以上烟田实践验证,取得了以下诸方面较大成果。这一研究,将为建设稳产保收烟田开展高光效栽培优质烟提供新途径。 (一)病虫草害方面:有效地压低田间病虫杂草的危害。尤以拒阻烟蚜和控制迄今最难防治
Selection of transparent polyethylene film is more light-temperature effect of silver gray film for the covering material, optimization of flue-cured tobacco cultivation technology model, rarely reported at home and abroad. Since 1982, after 6 years of in-depth research and more than mu of tobacco field practice verification, the author has made great achievements in the following aspects. This research will provide a new way to develop high-efficiency and high-quality cultivation of tobacco with stable yields. (A) pests and diseases: the effective reduction of harmful pests in the field. Especially to repel aphids and control the most difficult to prevent so far
