通过地膜覆盖与常规种植大区对比试验,结果表明:烤烟地膜覆盖栽培措施具有提高前期地温16、提早移栽期、促进烟苗早生快发的作用;但烤烟单位面积的产量、产值增加体现趋势并不很明显。反之,多年的地膜烟已造成了大量的朔料薄膜残留7,致使土壤生态受到严重破坏4,土壤质量逐年下降——为了给子孙后代留下一寸良好的土地可耕耘,建议立即停止地膜覆盖栽烟,改用无膜方式栽培。
The results showed that the plastic film mulching cultivation measures had the effect of increasing the pre-geothermal temperature 16 and earlier transplanting period, and promoting the rapid emergence of tobacco seedlings in the early growing season. However, the yield and output value of flue-cured tobacco increased Not obvious. On the contrary, many years of plastic film smoke has caused a large number of plastic film residues 7, resulting in serious damage to soil ecology 4, soil quality declined year by year - in order to leave an inch of good land for future generations workable, it is recommended to immediately stop the mulching Smoke, use non-membrane culture.
