一、适龄芒果树不开花的原因(一)气候因素。芒果的花芽分化要求光照充足,冬季及初春温度偏低,天气偏旱才有利于花芽分化。近几年,右江河谷一带冬春雨水偏多,光照不足,是影响芒果开花的外界因素。(二)种植过密。有的果园为了提高早期产量,实行密植。但当树冠扩大,相互遮荫后又不及时间阀,至使树冠交叉,通风透光不良,影响开花。(三)管理粗放,树势衰弱。由于管理粗放,缺乏水 First, the age of mango trees do not flowering reasons (a) climate factors. Mango flower bud differentiation requires adequate sunshine, winter and early spring temperatures are low, drought weather is conducive to flower bud differentiation. In recent years, the Youjiang River Valley winter and spring rain too much, lack of light, is the impact of mango blossom outside factors. (B) planting too dense. Some orchards in order to improve early production, the implementation of close planting. However, when the canopy is expanded and the shade of each other does not reach the time valve, the canopy intersects with poor ventilation and light and affects the flowering. (C) extensive management, tree weakness. Due to extensive management, lack of water
