| 摘 要： | 采用盆栽试验的方法,研究了土壤中残留地膜对番茄(Lycopersicon esculentum L.)幼苗形态及生理特性的影响.结果表明,残留地膜使番茄幼苗的株高、茎粗、地上部和根系鲜重、根系活力及叶片氮代谢水平等降低；而且根系的IBA含量降低和ABA含量增加,抑制了根系的生长.同时地膜残留量越大,抑制的效果越显著.这...

| Abstract: | The effects of plastic film (PF) residue on morphology and physiological characteristics of tomato (Lycopersicon esculentum L.) seedlings were studied by pot experiments. The results showed that PF residue inhibited growth of tomato seedlings. The plant height, stem diameter, shoot and root fresh weight, root activity and nitrogen metabolism were decreased. However, PF residue also reduced IBA content of root and ABA content increased, which inhibited lateral root growth, and the bigger was residue of PF, the more significant was inhibited effects. It suggested that the residue of PF had serious influences to the growth of tomato seedlings. |
