Abstract: To select the effective way for mulching and reutilize the gardening organic waste, Peristrophe japonica was mulched for 5 cm and 10 cm thick by one-year-old compost, fresh compost, wood chips and blocks. The results showed that organic mulched soil temperature at 20 cm depth was 1-4℃ higher than that of the control during September to November, and 2℃ higher during December to next February. However, mulched soil was 2℃ lower than the control after middle of March, and the difference became much smaller after late June. From late July, mulched soil was 0.5-1℃ higher than the control. Meanwhile, 30 cm deep soil moisture under mulching was 5% higher than the control (25%-30%) during November to next April. In terms of 60% sprouting of Peristrophe japonica, those mulched were 1 to 3 weeks ahead of the control, and the booming time was about 10 days ahead as well. The overall evaluation indicated that one-year-old compost was much better than the control. It was also confirmed by the measurements of height and spread of plants, fresh and dry weight of leaves, chlorophyll content of leaves etc. One-year-old compost was significantly better than the control and wood chips, it enhanced the growth and development of Peristrophe japonica, and was suitable for wide application.
