烤烟地膜覆盖栽培在我省是一项新技术。一九八二年我们和郴州地区农科所烟草室、桂阳县烟科所进行的地膜栽培试验结果表明:在同样的土壤、施肥条件下,与不盖膜的相比,具有明显的增产、增值、提早成熟的效果。从两个试验点来看:平均亩产329斤,比不盖膜的亩产增加21-26%;产值净增(除去地膜花费外)10-15%;成熟期提前三、四天。烤烟地膜覆盖栽培为什么会提高产量、增加产值,提早成熟呢?根据试验观察有以下几个原因:一、提高地温。我省3月中下旬至4月上旬正是烤烟移栽季节。此期常有寒潮,气温不
Flue-cured tobacco film mulching cultivation in our province is a new technology. In 1982, we and the Chenzhou Prefecture Department of Agriculture tobacco room, Guiyang County, tobacco cultivation conducted by the film showed that: in the same soil, fertilization conditions, compared with the non-membrane, with a significant increase , Value-added, early maturity effect. From the two pilot points of view: the average yield of 329 kg, 21-26% higher than the mu of non-membrane; net output (except for the cost of mulching) 10-15%; maturity of three or four days ahead of schedule. Flue-cured tobacco mulching cultivation why increase production, increase output value, early maturity? According to the experimental observation for the following reasons: First, to improve the ground temperature. In late March to early April in our province is the flue-cured tobacco transplanting season. This period often cold, the temperature is not
