配制疏松肥沃的床土是培育蔬菜壮苗的基础。当前,育苗床土的主要问题是孔隙度小(大孔隙少)、通气性差,其次是营养水平低。因此,配制床土必需从这两个方面加以改进。增加床土孔隙度的主要办法是增加床土中马粪比例,为提高营养水平可配合一定数量的化肥。促进秧苗发育和减少移苗伤根,播种床土有机肥比例应大些,土应少些;移植床土有机肥则少些,并增施化肥以提高营养 Preparation of loose bed soil fertility is the basis for nurturing vegetables. At present, the main problems of nursery bed soil are small porosity (less macropores), poor aeration, followed by low nutrient levels. Therefore, the preparation of bed soil must be improved from these two aspects. The main method to increase the porosity of bed soil is to increase the proportion of horse manure in the bed soil. In order to improve the nutrition level, a certain amount of fertilizer can be used. Promote the growth of seedlings and reduce the root of transplanted seedlings, the proportion of sown bed soil organic fertilizer should be larger, the soil should be less; transplant soil organic fertilizer is less, and increase fertilizer to improve nutrition
