Studies of Non-woven Fabric to Maintain the Temperature for Over-wintered Papaya (Carica papaya L.) Cultivation
Chang, M. T.
The plants of Carica papaya L. cv. Tainung 2 were covered wholly with 10 gm-2, 30 gm-2 and 50 gm-2 non-woven fabric and soil surface covering with 70 gm-2 since transplanted until fruit set were set to evaluate the plant growth, chlorophyll content, virus disease and temperature as compared with non-covering plants or just covering around the plants with PE cloth. The trunk diameter and plant height increase, leaf area and temperature were higher in the non-woven fabric covering (except 10 gm-2). The chlorophyll contents of the plants in the 10 gm-2 or 30 gm-2 non-woven fabric were not significantly different, while significantly lower in the 50 gm-2 covering. The ring spot virus disease could be isolated completely by non-woven fabric.
