新桩成活后,到夏秋季管理不得法,生长缓慢或停止生长,更甚者大量死亡,损失惨重。笔者经多年失败的教训,摸索总结出以下几个要点:一、遮阳:夏秋季阳光强烈,空气干燥,蒸发量大,新桩根少,所吸收的水分不能满足新桩所需,需进行遮阳,达到水分供求平衡。一天中,午后阳光最强烈,最需遮荫时间在12点以后,用65%～75%遮光率的遮光网较适宜。很多人总认为阴湿环境蒸发量小,桩易成活,整天遮阳不让其晒阳,其结果恰恰相反,环境阴湿、缺乏光照、温度低,新根不易萌发生长,严重会使新根、桩头切口腐烂,树桩死亡或长势减弱。合理利用阳光,能有事半功倍的效果。二、浇水:新桩浇水,见干见湿,以偏干为佳。长期过湿,即使蒸发量很大,根系也无法吸尽土壤中的水分,只要有很少的根系,就能吸收满足所需水分,因而根系就不再生长增多,树桩生长就减缓或停
After the survival of the new pile, the summer and autumn can not manage law, grow slowly or stop growing, not to mention a large number of deaths, heavy losses. After years of failure, the author explored the following points: First, the sun shade: summer and autumn sun strong, air-dried, large evaporation, less new pile, the water absorbed can not meet the needs of the new pile, the need to shade , To achieve a balance between water supply and demand. One day, the afternoon sun is the most intense, most need shade time after 12 o’clock, with 65% ~ 75% shading rate shading network is more appropriate. Many people always think that the evaporation of the wet environment is small, the pile is easy to survive, and the sun does not let it sun all day. The result is just the opposite, the environment is damp, lack of light, low temperature, new root is not easy to germinate and grow, , The pile head decayed, the stumps were dead or weakened. Rational use of sunlight, can have a multiplier effect. Second, watering: watering a new pile, see dry see wet, dry to a better side. Long-term over-wetting, even with large amounts of evaporation, roots can not desiccate moisture in the soil, and as long as there are few roots, they can absorb the water they need and grow no longer in the root system, stump growth slows down or stops
