每年8月份的持续高温干旱天气,会使柑桔发生异常落果,有的桔园因此减产达50%以上,严重影响桔农收入。1.夏季桔园落果原因据研究,柑桔类果树在幼果发育期(膨大期)要求有大量的水分,且最适温度为25~26℃,若在这一时期温度突然上升到35℃以上,会加剧蒸发,呼吸强度增大,蒸腾量大于根系吸收水分量,致叶片向幼果吸夺水分,幼果会因失水而大量脱
The continuous high temperature and drought weather in August each year will cause the abnormal fall of oranges, and some orange groves therefore cut their output by more than 50%, seriously affecting the income of orange farmers. 1. Summer orange peel fruit decay reasons According to the study, citrus fruit trees in the young fruit development period (swelling period) requires a lot of water, and the optimum temperature is 25 ~ 26 ℃, if during this period the temperature suddenly rose to 35 ℃ Above, will aggravate the evaporation, increased respiratory intensity, transpiration is greater than the amount of water absorbed by the root, causing the leaves to young water absorption, young fruit due to dehydration and a lot of off
