Abstract:

In order to identify the heat preservation of bast fiber mulching film and its effects on growth and yield of crops in different seasons, the comparison tests of Chinese cabbage covered by different films have been conducted in winter, spring and summer respectively. The results showed that bast fiber mulching film could increase the soil temperature in different seasons and the effects were stable. In summer, the temperature under the bast fiber mulching film would not reach too high. With the covering of bast fiber mulching film, it could increase the rate of leaf emergence, the plant height, leaf number and leaf area. The interaction between different seasons and different covering was significant (P<0.01). And the yield-increasing effects in spring and summer were more remarkable than winter. The yield of Chinese cabbage covered with bast fiber mulching film in spring and summer were 45.97% (P<0.05) and 48.89% (P<0.05) respectively higher than that of Chinese cabbage without film; which were also 6.66% (P<0.05) and 51.05% (P<0.05) respectively higher than that of Chinese cabbage covered with plastic film.
