烤烟地膜覆盖栽培是从日本引进的技术。日本从五十年代到六十年代就在少叶型烤烟和晒晾型烟上,进行了多方面的试验,有关多叶型烤烟品种地膜覆盖栽培尚无报导。为了解决我省无霜期短和栽种生育期长多叶型品种的矛盾,我所于1980年开始进行薄膜覆盖垄面,栽种多叶型品种“辽烟十二号”的小面积试验,1981年又在所外进行多点示范,现将结果整理如下。 一、示范概况 1980年在所内进行不同烤烟品种试验,供试品种为“辽烟十二号”和“Coke γ86”。1981年增加了“7100”和“NC 2326”两个品种。覆膜分:田间整个生育期;田间生育前期和对照。
Flue-cured tobacco film mulching is a technique imported from Japan. Japan from the fifties to the sixties on the leaves of flue-cured tobacco and sun-dried tobacco on the conduct of a wide range of experiments, the multi-leaf flue-cured tobacco varieties covered in plastic film has not been reported. In order to solve the contradiction between the short frost-free period and long leafy varieties in our province, we started the small-area experiment of film covered ridge and planted multi-leaf variety “Liaobu 12” in 1980. In 1981, Beyond the multi-point demonstration, the results are organized as follows. I. Model Overview In 1980, different varieties of flue-cured tobacco were tested in the institute for “Liaoyuan Twelve” and “Coke γ86”. In 1981 an increase of “7100” and “NC 2326” two varieties. Film covered: Field throughout the growth period; Field pre-and post-control.
