所谓“僵苗”,是指由于水肥不当等原因引起的花苗呆滞不长现象,此时花卉呈不死不活的状态。对付这种“僵苗”,最好的办法就是“干旱疗法”。即在一定时间内(20天、2个月或更长时间,视不同花卉的不同情况而定)断绝水分供应,迫使花苗在干旱的环境下增加新根的生长,直到花苗长好了新根,再给予正常的水肥供应,到那时“僵苗”必然迅速恢复生机,快速生长。这是植物的生理特性决定的。因为在干旱条件下,花苗为了生存,必然要长出更多的新根,以求获得维持生命必需的水分。另外盆土在干旱时透气良好,也有利于新根
The so-called “stiff Miao” refers to the phenomenon of sluggish flower seedlings caused by improper water and fertilizer and other phenomena, when the flower was immortal state. The best way to deal with this “stiff water” is “drought treatment.” That is, within a certain period of time (20 days, 2 months or more, depending on the different circumstances of flowers) cut off the water supply, forcing the seedlings in the arid environment to increase the growth of new roots until the seedlings grow a good new root , Then give the normal supply of water and fertilizer, then “stiff Miao” is bound to quickly restore vitality and rapid growth. This is determined by the physiological characteristics of the plant. Because in the dry conditions, flower seedlings in order to survive, it is bound to grow more new roots, in order to obtain the necessary water to maintain life. In addition basin soil permeability in the drought is good, but also conducive to the new root
