摘要
研究了稻草不同覆盖量以及地膜覆盖对烟株生长发育、产量和品质的影响。结果表明，地膜覆盖和稻草覆盖栽培均能有效的促进烟株生长，提高烟叶产量，改善烤烟的经济性状；稻草覆盖栽培对烟株生长的促进作用虽不及地膜覆盖处理明显，但对提高烟叶均价及品质方面效果显著；在稻草覆盖量3000—7500kg·hm^-2范围内，其产量、品质和产值与其用量呈正相关。
The effects of straw mulching and film mulching on flue-cured tobacco growth and quality were studied in field. The results showed that straw mulching and film mulching could raise tobacco yield, improve the economic characteristics and accelerate the growth and development of flue-cured tobacco. The plant with straw mulching grew slower than that with film mulching,but the effects of straw mulching on quality and production value were more remarkable. In the scope of 3000 -7500 kg · hm^-2 ,the relationship between effects of quality,yield and production value and amounts showed positive correlation.
