壮苗是丰产的基础，而床土是培育壮苗的基础。床土配制的好坏是培育壮苗成败的关键。因为种子播在土内，种子的萌发、生长，发育所需的水分，养分都需从床土中吸收。因为床土的温度、湿度、酸碱度和通气性等与根的吸收作用有密切关系。所以，育苗土应配制成不但要含有丰富的有
Strong seedling is the basis of high yield, and soil bed is to cultivate strong seedling foundation. Bed soil preparation is the key to the success or failure of strong seedlings. Because the seeds are sown in the soil, the germination, growth and development of the seed require nutrients and nutrients to be absorbed from the soil. Because bed soil temperature, humidity, pH and air permeability and the absorption of the root has a close relationship. Therefore, nursery soil should be formulated not only to have rich
