环割时间和环割量对油茶果实养分及经济特性的影响
Effects of Girdling Time and Amount on Fruit Nutrient and Economic Characteristics of Camellia oleifera
摘要
Abstract
[Objective]In order to explore the effects of different girdling treatments on the nutrient and economic characteristics of Camellia oleifera fruits,this study aims to find out the girdling methods which are suitable for increasing the yield of Camellia oleifera.[Method]Seven-year-old Camellia oleifera was used as experimental materials to study the effects of different girdling periods and amounts on the inorganic nutrients and organic nutrients in Camellia oleifera fruits and the related economic properties of Camellia oleifera fruits and camellia seeds.[Result]The fruit soluble protein content,fruit shape index and oil yield per plant were significantly increased by girdling at full bloom stage and before physiological fruit falling.Specifically,the fruit soluble protein content was significantly increased by girdling at full bloom stage,while the oil yield per plant increased more significantly by girdling before physiological fruit falling.The rate of dry kernel and oil yield of dry seeds were significantly reduced in the two-ring cutting periods,and the inhibition effect of ring cutting before physiological fruit drop was greater.The treatment of 360° and 180° circumcision significantly reduced the fresh weight of single fruit,the vertical diameter of fruit,the percentage of dry seeds from fresh fruit and the percentage of dry kernel from dry seeds,and the inhibition effect of 360° circumcision was more significant.With the increase of fruit yield,the content of soluble sugar,soluble starch and total nitrogen decreased,and most of the economic characteristics,such as kernel yield and oil yield,became lower.[Conclusion]Girdling can reduce the economic characteristics of fruit in different degrees,it can promote the yield increase of fruit,and the effect of girdling before physiological fruit drop is more obvious than that at full flowering stage.关键词
