Mulching with plant residues is a common method used in agricultural and forestry production, which has significant effects on soil moisture conservation, soil fertility improvement, plant growth promotion and solving the problem of soil bareness. In recent years, the application of green waste to urban green land mulching is the focus of landscape industry in China and abroad and the main application and development direction of compost besides returning to soil. At present, the research and application of green waste mulch mainly focus on composting mulch and dyeing mulch, and there are few reports on the systematic comparison of the mulch effects of different components of native materials. For proven after simple processing green waste native materials mulching influence on plant growth, taking Ixora chinensis Lam. as the research object, the green wastes were collected according to turfgrass clippings (TCS), leaves (LVS), mixture of branches and leaves (MBL), branches (BCS), and then were crushed, air-dried as native mulches material to test and set up three mulching thickness (3 cm, 6 cm and 9 cm), with bare soil without mulch as the control. The effects of different treatments on growth parameters, mineral nutrients and SPAD of above-ground parts of I. chinensis Lam. were analyzed after 21 months of planting. The results showed that compared with the control, mulches significantly increased the plant height, stem diameter, biomass, SPAD and N content in stem and leaf of I. chinensis Lam. The variation trend of P content in stem and leaf and K content in stem of each treatment was different due to the difference of mulch material type and thickness, but had no obvious effect on leaf K content. The results of correlation analysis showed that there was a very significant positive correlation between the growth parameters and the N content of stems and leaves and SPAD, and the P content was significant positive correlated with the weight of fresh leaves. Comprehensive evaluation by principal component analysis indicated that mulches treatments on each index of the comprehensive performance of I. chinensis Lam. was superior to the control. Treatments could be divided into two categories according to principal component comprehensive, category one, MBL & BCS with the thickness of 3 cm, 6 cm, 9 cm LVS with 6 cm and 9 cm with better effect on promoting the growth of Ixora chinensis Lam., and category two, TCS with thickness of 3 cm, 6 cm, 9 cm and LVS with thickness of 3 cm with relatively poor growth promoting effect. This study screened out the components and mulching thickness of green waste raw materials suitable for organic mulch through comparative evaluation of the indexes affecting the growth of I. chinensis Lam., which could provide reference for the promotion and application of green waste as organic mulch.
