怎样才能使仙人球安全越夏?实践证明,在管理上必须抓好“五防”。一、防雨淋。夏季雨水较多,放在露天院中、阳台上以及荫棚下的仙人球,如遇雷阵雨、连阴雨等,要及时搬入室内通畅处避雨。因雨淋后会导致盆内积水,使盆土缺氧,根不能进行正常呼吸,极易引起仙人球沤根而死亡。如不慎已遭雨淋,应立即松土,加快水分蒸发速度,促使根的生理功能正常。二、防日灼。日灼是夏季发生在仙人球上的一种常见现象,主要原因是高温下强烈的日光照射灼伤了多肉的球体,被灼伤部位组织坏死,影响球体生长。因此,夏季要做好仙人球的遮荫工作,当气温达35℃以上时,中午前后应将仙人球移到阳光直射不到的地方。在上午10时以前或下午5时以后,可将仙人球置于阳光下,以促使多孕育花蕾。三、防缺水。夏季是仙人球的生长旺季,需水量相应增加,如水分供应不足,则仙人球的生长会受到严重阻碍。因此,夏季(尤其遇到干旱)要勤浇水。夏季最好的浇水时间是在清晨和傍晚,因此时气温相对较低,浇水后易被
How to make cactus safe summer? Practice has proved that management must do a good job, “five defenses.” First, anti-rain. More summer rain, on the open courtyard, the balcony and the shade of the fairy under the shed, such as case of thunderstorms, even the rain, etc., should be promptly moved into the indoor patency shelter. Due to the rain will lead to basin water, so that soil hypoxia, the root can not be normal breathing, can easily cause prickly heat and death. If it has been accidentally rain, should immediately loosen the soil, speed up the evaporation rate of water to promote the normal physiological function of the root. Second, anti-sun burning. Sunburn is a common phenomenon that occurs in prickly pear in the summer. The main reason is that the intense sunlight burns the fleshy sphere at high temperature, and the tissue is necrotic at the burned site, which affects the growth of the sphere. Therefore, in the summer to make the cactus shade work, when the temperature reaches 35 ℃ above, before and after noon should be moved to the place of direct sunlight. In the morning before 10 o’clock or after 5 pm, the prickly heat can be placed in the sun, in order to promote more flower buds. Third, anti-water. Summer is the cactus growth season, a corresponding increase in water demand, such as water supply, the growth of cactus will be seriously hampered. Therefore, the summer (especially in drought) to diligent watering. Summer best watering time is in the early morning and evening, so when the temperature is relatively low, easily after watering
