In order to explore the in uence of the application mode of household food waste compost products on plant growth characteristics, the study applied the waste compost products to Lagerstroemia indica and the Ligustrum quihoui in the outer ring forest belt of Minhang, Shanghai by spreading and furrowing, set up a control group, the chlorophyll content, leaf area, fresh weight, dry weight, and DBH of Lagerstroemia indica and Ligustrum quihoui were observed before application, 3 and 5 months after use,  nally, evaluated the optimal fertilization method. The results showed that the increment of chlorophyll content, leaf area, fresh weight, dry weight, and DBH of Lagerstroemia indica and Ligustrum quihoui were higher than those of the control P＜0.05. The chlorophyll content, leaf area, fresh weight, dry weight, and DBH of Lagerstroemia indica and Ligustrum quihoui treated by furrow increased signi cantly, which was more conducive to the growth of plants. The study veri ed that food waste compost products could improve plant growth and provide a scienti c and reasonable application mode for the ef cient use of food waste compost products.
