黑白双色地膜在烤烟生产上的应用研究

Application of Black and White Double Color Film in Flue-cured Tobacco Production

[目的]探索黑白双色地膜在烤烟生产上的应用。[方法]在陇县曹家湾镇流渠村进行黑白地膜与常规透明白色地膜对烤烟生长的影响的分析研究。[结果]试验表明,黑白地膜团颗期之前膜下温度高,烟叶在移栽期到团棵期生长较快,黑色部分的吸热作用明显;团棵期之后,白色透明地膜膜下温度较高,反光率明显好于黑白双色地膜,烟叶开片较好,产量、产值、桔黄烟比例相对较高。同时,黑白地膜具有遮阴的作用,能够有效防治垄内杂草生长。[结论]研究可为黑白双色地膜在烤烟生产上的应用提供理论和实践依据。

[ Objective ] To explore application of black and white double color film in flue-cured tobacco production. [ Method ] Effects of black and white double color film on flue-cured tobacco growth were studied in Liuqu Village, Caojiawan Township, Longxian County. [ Result] The results showed that the black and white film has high temperature before group period, tobacco leaf stage in transplanting to the mass of trees grow faster, the black part of the endothermic effect is obvious ; group tree period after the white transparent plastic film under high temperature, re- flective rate is significantly better than black and white and double color film, tobacco leaves open is better, production, output, orange smoke ratio is relatively high. At the same time, black and white film have the function of the shade, can effectively control weeds in the ridge. [ Con- clusion] The study can provide theoretical and practical basis for application of black and white double color film in flue-cured tobacco produc- tion.
