于浇水过多或经霉雨季节后又把仙人掌类植物置于阴暗潮湿、通风不良的地方,这样就造成盆土水分饱和、严重缺氧,致使土壤中具有分解有机物功能的胺化细菌、硝化细菌及硫化细菌等好氧性微生物的正常活动受阻,不能有效地分解土壤中的有机物,从而使仙人掌类植物因得不到土壤中的各种矿物质营养而出现萎黄、蔫软等症状。没有莳养经验的人,往往误认为是植物缺水所致,于是便不断地浇水,因此造成烂根、烂茎,甚至死亡。在土壤过湿过酸的状态下,产生上述情况后,必须采取有效措施加以挽救。特别是久雨后天气突然转晴,不应立即将仙人掌类植物放到烈日下曝晒,应把它们放在阴凉通风的地方1-2天后再见阳光,让其慢慢
In the water too much or after the moldy season and then the cactus plants in the dark damp, poorly ventilated place, resulting in peat soil moisture saturation, a serious lack of oxygen, resulting in the decomposition of organic matter in the soil of the aminated bacteria, Nitrobacteria and sulfur bacteria and other aerobic microorganisms blocked the normal activities of microorganisms, can not effectively decompose the organic matter in the soil, so that cactus plant due to various minerals in the soil nutrients appear chlorosis, 蔫 soft and other symptoms. Those who lack experience in farming often mistakenly believe that they are caused by water shortage in plants and they are therefore constantly watered, resulting in rotten roots, rotten stems and even deaths. In the state of soil too wet too acid, after the above situation occurs, we must take effective measures to be saved. Especially after a long rain suddenly sunny weather, cactus plants should not be immediately exposed to the sun, should be placed in a cool and ventilated place 1-2 days after the sun, let it slowly
