特效植物营养素对蜜柚果实的影响(英文)

目的]研究特效植物营养素对蜜柚果实的影响。方法]在蜜柚谢花后开始用特效植物营养素(SPNE)喷施植株,间隔20 d以上再喷施,采收前一共喷了4次,比较了SPNE处理和对照产量及品质的差异,果实重量及外观表现的差异,果肉球重量及内观差异。结果]SPNE使蜜柚的单株成果数比对照多,平均果重增加因而提高产量,在提高产量的同时使维生素C及可溶性固形物高于对照品质更好。用SPNE处理过的果实外观比对照大且色泽靓丽、光洁无疤、形状漂亮,外果皮比对照果皮稍薄,果肉球重量比对照增加且外观圆润光洁,尤其是果肉瓣比对照大分布均匀无内裂,果肉比对照更晶莹透亮口感更佳。结论]为促进蜜柚生产更加优质高产提供理论依据。

Effects of Special Plant Nutritional Elements on Honey Pomelo Fruits

Objective] The effects of special plant nutritional elements on honey pomelo fruits were investigated. Method] After the honey pomelo flowers faded, the special plant nutritional elements （SPNE） were sprayed on the honey pomelo plants. After an interval of 20 d or more, the SPNE were sprayed again. A total of 4 times of spraying were carried out before the harvesting. Then difference in yield, quality, fruit weight, fruit appearance, ball weight and internal characteristics were compared between the SPNE treatment group and the control group. Result] Compared to that of the control group, the fruit number per plant of the SPNE treatment group was more, and the average fruit weight was higher, resulting in the higher yield in the SPNE treatment group. At the same time, the vitamin C and soluble solids con- tent in honey pomelo fruits of the treatment group was higher than that of the con- trol group. The quality of honey pomelo fruits was higher in the SPNE treatment group. The honey pomelo fruits treated with SPNE were bigger, more shining and cleaner. The fruits in the treatment group had no scar, but had more beautiful shape. The exocarp of the treatment group was thinner than that of the control group. The ball weight of the treatment group was higher than that of the control group. Moreover, the ball appearance of the treatment group was cleaner. In the treatment group, the pulp segments were bigger and more consistent in size. In ad- dition, there were no internal cracks in the pulp segments. The fruits of the treat- ment group were more sparkling and more transparent. They tasted better. Con- clusion] We hoped to provide a theoretical basis for the high-quality and high-yield- ing production of honey pomelo.
