摘要:

本研究以大棚延后栽培的‘南丰蜜橘’作为研究材料,结合覆盖材料与保水剂做树盘试验处理,分析不同树盘处理对浮皮程度、果实品质和树盘土壤温湿度的影响。结果表明:在果实成熟的11月,树盘覆盖处理可提升果实可溶性固形物(TSS)、可滴定酸(TA)和维生素C含量,反光膜+保水剂处理提升果实TSS和TA效果显著,分别较对照(CK)高2.30%、0.27%。果实浮皮程度与TSS、TA和维生素C含量负相关;在12月,CK和稻草处理果实TSS、TA含量低,浮皮趋于严重,浮皮程度分别高达1.67级、1.07级,而其他处理果实出现轻度浮皮,均为0.73级。浮皮程度与单果重、果实TA和维生素C含量有很大关联性;在翌年1月,浮皮程度与土壤湿度呈极显著正相关(相关系数为0.879),而TA与土壤湿度呈极显著负相关(相关系数为-0.911)。反光膜+保水剂处理土壤湿度一直处于最高,此时期TA迅速降低,浮皮程度呈加速趋势。因此,土壤湿度越高,浮皮程度越严重,果实的TSS、TA和维生素C含量越低。通过覆盖处理能降低土壤湿度,提升果实TSS、TA和维生素C含量等品质,推迟‘南丰蜜橘’果实浮皮的发生,减轻果实浮皮程度。其中,地布覆盖处理防治果实浮皮效果最佳,反光膜、地毯、地布+保水剂处理的效果次之。

Abstract:

Nanfeng tangerine (Citrus reticulata Blanco cv. Kinokuni) during delayed cultivation in greenhouse was used to investigate the effects of different mulching treatments by combining cover materials and water-retaining agents on the puffing degree of fruit, fruit quality and soil temperature and humidity. In November, mulching treatments increased the content of TSS, TA and vitamin C in fruit, while the combined treatment of reflective film and water-retaining agent significantly improved the content of TSS and TA, 2.30% and 0.27% higher than the control respectively. The puffing degree of the fruits was negatively correlated with Total?Soluble?Solid (TSS), titratable acid (TA) and vitamin C content. In December, the fruits by mulching straw and CK treatments showed lower content of TSS, TA and more puffing. The puffing degree by mulching straw and CK treatments reached 1.67 grade and 1.07 grade respectively, and that for the other treatments was mild, only 0.73 grade. The puffing degree was closely related to fruit weight, TA and vitamin C content. In the following January, the puffing degree was positively correlated with soil humidity with a correlation coefficient 0.879, while TA content was significantly negatively correlated with soil humidity with a correlation coefficient -0.911. The humidity of soil in the combined treatment of reflective film and water-retaining agent was always at the highest level. The TA content decreased rapidly during this period, and the puffing degree showed an accelerated trend. Therefore, it was concluded that higher soil moisture led to more puffing degree, less TSS, TA and vitamin C. It could reduce soil humidity, improve fruit TSS, TA and vitamin C content, delay the occurrence of puffing degree by mulching treatment. Among them, the effect of garden cloth treatment was the best, with the effect of reflective film, carpet and garden cloth+ water-retaining agent followed.
