地膜覆盖栽培对胡麻衰老进程的影响

Effect of Mulch with Plastic Film on Senescence Progress of Flax

通过对地膜胡麻和露地胡麻在各个时期根系活力及叶绿素含量进行研究,结果表明:地膜覆盖胡麻最大根系活力高于露地胡麻,但衰老速率高于露地胡麻;最大叶绿素含量两者相当,但地膜胡麻叶片衰老速率高于露地胡麻。因此认为地膜胡麻的适应区域是高山冷凉山区。

The root activity and chlorophyll content in several period of flax between mulch with plastic film and open ground were researched.The results showed that the max root activity of mulch with plastic film were higher than that of open ground,but the senescent speed of the former were faster than that of the latter;the max contents of chlorophyll were equal between mulch with plastic and open ground,but the senescent speed of the former were faster than that of the latter.Thus the adaptive fields of flax under the mulch with plastic film were the areas of high and cold.
