| 为了减少普通地膜连年使用造成的农田白色污染，为蔬菜生产选择高效环保地膜提供参考，以“耐寒优秀”青花菜为试材，研究高效环保地膜连续使用4年对青花菜生长发育的影响。结果表明：高效环保地膜连续使用3～4年，青花菜产量略有减少，但差异不显著；青花菜生长发育与对照普通黑色地膜和银灰色地膜2个处理没有明显差异；土壤容重有所降低；除草效果好于对照地膜，且回收容易，不易撕裂，没有残留，可以作为普通地膜的替代品。 |

| Abstract: In order to reduce the white pollution of farmland caused by the continuous use of common mulch film and provide a reference for the selection of high-efficiency and environmental-friendly mulch film for vegetable production, the effects of continuous use of high-efficiency and environmental-friendly mulch film for 4 years on the growth and development of broccoli cultivar 'Naihanyouxiu' were studied. The results showed that when the high-efficiency and environmental-friendly mulch film was continuously used for 3～4 years, the yield of broccoli decreased slightly, but the difference was not obvious. The growth and development of broccoli had no significant difference with the control of common black mulch film and silver-gray mulch. The soil bulk density decreased. The weeding effect of the mulch film was better than that of the control mulch film, which was easy to recover and not easy to tear, and there was no residue, which could be used as a substitute for the common mulch film. |
