甜橙的果实发育强烈地抑制花芽分化,所以花量的多少与上年产量呈反比。这是形成大小年结果的直接原因。在相似载果量的条件下,花量大小与上年10～11月积温呈直线正相关。花量小时,营养枝比例 ,即叶面积大,因而着果率高,座果率与花量呈Y=aX~(-b)相关(Y:座果率,X:花量)。载果量与花量或营养被均呈Y=a+bX-cX~2相关(Y:载果量,X:花量或营养枝数)。即可根据花量或营养枝数来测产和控制产量。本试验当实生甜橙与锦橙的花量为3.2朵/母枝、营养枝25％左右时,产量最高;但是为了保持树势和稳产,最好控制营养枝在60～50％,花量在1.5～2.0朵/母枝,这样,可获得相当最高产量的80～90％的产量。
The fruit development of sweet orange strongly inhibits flower bud differentiation, so the amount of flower is inversely proportional to the previous year’s yield. This is the direct cause of the size year result. In similar conditions, the amount of flowering was positively correlated with the accumulated temperature from October to November last year. The flowering hours, the proportion of vegetative shoots, that is, the leaf area is large, so the fruit rate is high, fruit set rate and flowering was Y = aX ~ (-b) related (Y: fruit rate, X: flower). The amount of fruit and flower or nutrition were Y = a + bX-cX ~ 2 (Y: fruit load, X: flowering or vegetative branch number). According to the amount of flowers or nutrition to test and yield production control. In this experiment, the yield of sweet orange and Jincheng was the highest when the flower amount of sweet orange and Jincheng was 3.2%, and the nutrition branch was about 25%. However, in order to maintain the vigor and stability of the tree, it is best to control the nutrition branch at 60 ~ 50% In 1.5 ~ 2.0 flowers / mother branch, so that you can get the equivalent of the highest yield of 80 to 90% of the yield.
