Abstract:

To promote the experimental demonstration，popularization，and application of new varieties，new technologies，new cultivation models，and new products in the vegetable industry，and to accelerate the green transformation and upgrading of the vegetable industry，in conjunction with the relevant tasks of the Zhejiang New Melon and Vegetable Varieties Conference，a total of 27 fully biodegradable mulch film products with different thickness specifications and colors from 9 manufacturers were introduced. A demonstration experiment on spring cabbage covered with biodegradable mulch films was conducted. The results showed that the mulching effects of different biodegradable mulch films were generally consistent with those of ordinary PE mulch films，with no adverse effects on the growth and yield of cabbage，and the differences were not significant，indicating that they could meet the requirements of cabbage cultivation under film mulching. Compared with no mulching cultivation，film mulching could advance the growth period and increase the yield of cabbage.

Key words: biodegradable mulch film, Zhejiang, cabbage, yield
