Effects of Different Shoot-Fruit Management on Fruit Diameter and Production Benefit of Cuimi Kumquat
摘要
Abstract
[Objective]The cultivation area of Cuimi kumquat in Guangxi accounts for more than 90%of the total planting area in China.The fruit diameter is one of the important factors that determine the price of Cuimi kumquat and an important index affecting the benefit.This study aimed to explore the effects of different shoot and fruit managements on fruit diameter and benefit in Cuimi kumquat production,to summarize the shoot and fruit management techniques for Cuimi kumquat,in order to improve the cultivation technology for Cuimi kumquat production and provide a scientif-ic reference for increasing the production efficiency.[Method]Three adjacent representative or-chards with similar conditions were selected,and unified management of flower and fruit protection,fertilization,water and fertilizer were applied.Three different shoot and fruit management treat-ments were set:A,fine management,manual fruit thinning 5 times,carefully selecting strong branch length about 20 cm,limiting number of branches,and branch angle unified management 3 times;B,medium management,manual fruit thinning 2 times,carefully selecting strong branch length about 20 cm,limiting number of branches,and branch tip length and branch angle unlimited management 2 times;and C,general management,no fruit thinning,no limiting number of branch-es,and branch tip length and branch angle unlimited management 2 times.The characteristics related to fruiting,fruit longitudinal&transverse diameter,and yield were statistically investigated,and the factors affecting fruit diameter and production benefit were analyzed.[Result]The experiment re-sults showed that the fruit was similar in shape in different shoot and fruit management treatments.The fruit shape index was 1.04≤G≤1.08 with no significant difference in the content of soluble solids and fruit hardness.The main indicators were significantly higher in treatment A than other treat-ments,which shoot-fruit ratio was 1.69,fruiting branch length was 19.10 cm,fruiting branch diame-ter was 5.01 mm,fruit diameter was 39.57 mm,proportion of fruits in third and higher classes reached almost 100%.The production benefit per plant was the highest in treatment A,which was 38.15%higher than that in treatment C,and 79.00%higher than that in treatment B.Correlation anal-ysis showed shoot-fruit ratio,fruit branch length and fruit branch size were extremely significantly and positively correlated with fruit diameter.[Conclusion]Reasonable shoot and fruit management can significantly increase the fruit diameter,improve single fruit weight and yield,and improve the production efficiency.In the production of Cuimi kumquat,we should focus on optimizing the fruit-ing branch length and branch diameter,so as to develop appropriate fruiting branches.At the same time,the shoot-fruit ratio must be properly adjusted,to ensure that the vegetative growth of the tree is good enough to provide sufficient support to the reproductive growth.In order to realize high qual-ity and efficient production of Cuimi kumquat,it is recommended to maintain the following tree state:shoot-fruit ratio 1.55～1.93,fruiting branches length 17.92～21.12 cm,and fruiting branch di-ameter 4.72～5.50 mm.关键词
