蔬菜幼苗分苗后死苗的主要原因有五条,一是分苗床土温过低,幼苗分到苗床后迟迟不能扎根而造成死苗;二是苗床土拌入未腐熟有机肥不均匀,引起烧根死苗;三是分苗时一次起苗过多,一时分不及使幼苗失水过多,分后不易恢复而死苗;四是幼苗在分苗前发育不好,根系少;五是分苗过晚,造成伤根,吸收能力衰弱而死苗。 There are five main causes of dead seedlings after vegetable seedlings, one is sub-seedbed soil temperature is too low, the seedlings into the seedbed delay can not take root and cause dead seedlings; Second, seedbed soil mixed with not decomposed organic fertilizer uneven, causing Burned root dead seedlings; third is when the seedling seedling too much time, less than one hour to seedling dehydration too much, not easy to recover after the dead seedlings; Fourth seedlings in the seedlings before the development of poor, less roots; Seedling too late, resulting in wounds, weakness and dead seedlings.
