利川市地处鄂西南山区,属云贵高原东延部分。大部分地区土质和气候特点适宜生产优质烟。但海拔1200米以上的高山区,由于春迟秋早、雨量偏多,烤烟生产前期和成熟期后期气温偏低,适宜生育期较短,影响烟叶的质量和产量。为提高我市烟叶质量,综合营养垛假植和地膜覆盖栽培两者的优点,1986年我们开展了烤烟营养垛假植地膜覆盖栽培综合应用试验,现将试验结果初报如下。
Icheon City is located in the mountainous area of southwestern Hubei Province, belonging to the eastward extension of the Yunnan-Guizhou Plateau. Most parts of the soil and climate characteristics suitable for producing high-quality smoke. However, in the high mountainous areas above 1200 meters above sea level, due to early spring, late autumn and heavy rainfall, the temperatures in the early and late flue-cured tobacco production are low and the suitable growth period is short, which will affect the quality and yield of tobacco leaves. In order to improve the quality of tobacco in our city, integrated trophies and mulch plastic film mulching the advantages of both in 1986, we conducted a comprehensive application of trophic tobacco tillable plastic film mulching cultivation of comprehensive application test, the test results are as follows.
