Abstract
Plastic film mulching and plant density are important cultural practices to improve crop productivity. In the current study, field experiments were conducted to examine the effect of plastic film mulching and different plant densities on rice growth and yield in Northeast China in 2009 and 2010. Six treatments were tested as follows: mulching and plant density at 10 cm×30 cm (M10), mulching and plant density at 15 cm × 30 cm (M15), mulching and plant density at 20 cm×30 cm (M20), mulching and plant density at 25 cm×30 cm (M25), mulching and plant density at 30 cm×30 cm (M30), and non–mulching (NM). Plastic mulching improved plant height and leaf area index (LAI). The leaf area index of M10 was significantly greater than NM (P<0.05) in both years. Rice yield with mulch was also significantly higher than non–mulched treatments. Different plant density under plastic film mulching had little effect on plant height. The LAI of different density treatments decreased gradually with the reduction of plant density. Yield of M10, M20, M25 and M30 was significantly greater than that of M15 in 2010. In the experiment, the maximum yield was obtained in the M10 treatment, and yield of M10 was significantly greater than that of NM in 2009-2010 and M15 in 2010. Thus, plant density of 10 cm×30 cm is most favourable for rice production under plastic film mulching in saline-sodic soil of Northeast China.
