一、水分管理蔬菜成苗期,外界气温高,秧苗生长量又大,应保证充足的水分。不要用干旱的办法蹲苗,以免秧苗老化;也不要小水勤浇,使表土板结,影响根系发育。要灌大水,灌后放风,并在土壤宜耕时用小铁钩松开表土。这样既能保墒,又能保持土壤疏松干燥,保证秧苗健壮成长。 First, the water management Vegetable seedling stage, the outside temperature is high, the growth of large seedlings, should ensure adequate water. Do not use the arid approach squat seedlings, so as not to seedling aging; also do not pour a small water, so that topsoil compaction, affecting root development. To fill floods, irrigation after the wind, and when the soil should be a small iron hook to loosen the topsoil. This will not only soil moisture, but also keep the soil loose and dry, to ensure the robust growth of seedlings.
