生产实践证明，棚室冬茬黄瓜生长发育期间需要大量水分，总结各地实践经验一般必须把好“八关”一、定植期浇水头定植前必须选好底墒。为确保有足够水分供应幼苗生长需要，在底墒足的基础上，仍应采取水稳苗法进行定植，才能确保幼苗顺利度过缓前扎根阶段。二、扎根推浇水关当? Production practice has proved that winter greenhouse cucumbers need a lot of water during growth and development, summarize the practical experience around the general must be good “eight off” First, the planting of watering head must be selected before planting end moisture. In order to ensure adequate water supply for the growth of seedlings, water-stable seedling method should still be adopted for grafting on the basis of soil moisture content, so as to ensure that the seedlings can be smoothly rooted and rooted. Second, take root when pushing water?
