不同地膜对大棚春播胡萝卜生长影响的研究

Effect of Different Plastic Film Mulching on Growth of Spring Carrot in Plastic Canopy

通过对大棚春播胡萝卜进行覆盖黑地膜、普通透明地膜和未覆膜栽培进行研究,结果表明:覆盖黑地膜、普通透明地膜比未覆膜分别提前13,6 d达到商品根质量,延长了在地时间,增加了产量,且根表皮更光滑;为尽早上市,大棚春播胡萝卜栽培应覆盖地膜,且优先选择黑色地膜。

In order to study the effect of different plastic film mulching on growth of spring carrot in plastic canopy,the experiment was conducted with black plastic film,transparent plastic film ordinary,and with no film as control.The results showed that carrot with black plastic film or transparent plastic film ordinary could be marketed at13,6d earlier than the control,respectively;and the yield were increased significantly.In order to market as early as possible,spring season carrot should be mulched plastic film in plastic canopy,and the black film was optimal.
