为研究冬季不同覆膜处理对W.默科特杂柑落果率及果实品质的影响,在11月中旬至翌年2月对重庆市长寿区龙河果园W.默科特采取3种不同的树冠和地面覆膜组合进行处理,并统计分析各处理落果率和果实品质的差异。结果表明,与对照(空白)相比,冬季覆膜处理降低W.默科特果实可溶性固形物、可滴定酸、维生素C含量,提高固酸比,对果实色泽有促进或延缓作用;冬季各覆膜处理能够有效地降低W.默科特冬季落果率,以地面覆反光膜+树冠覆膜效果最好。
In order to study the effect of winter mulching treatments on fruit drop rate and fruit quality of W. Murcott, 3 different canopy patterns were collected from mid-November to February of the following year in W. Murcott, Longhe Orchard, Changshou District, Chongqing And ground laminates were processed, and the differences of the fruit drop rate and fruit quality were analyzed statistically. The results showed that compared with the control (blank), winter mulching decreased the soluble solids, titratable acidity and vitamin C content, increased the ratio of solid to acid, and promoted or retarded the fruit color. In winter Coating treatment can effectively reduce W. Murcott winter drop rate, the best film to the ground coating + crown laminating effect.
