在制作营养钵时,将有机肥与无机肥、速效肥与迟效肥相结合,氮、磷、钾三要素按一定比例混配,是培育壮苗的物质基础。但若用肥不当,特别是化肥用量过多,或土、肥掺拌不匀,往往造成肥害,影响全苗和壮苗。为此,我们进行了钵土施肥试验,取得了以下结果,可供参考。 In the production of nutrition bowl, the organic fertilizer and inorganic fertilizers, quick-acting fertilizer and delayed combination of fat, nitrogen, phosphorus and potassium by a certain percentage of three elements are mixed, is the material basis to cultivate strong seedlings. However, if improper use of fertilizers, especially excessive use of fertilizers, or soil, fertilizer mixed with uneven, often resulting in fat, affecting the whole seedlings and strong seedlings. To this end, we conducted a potting soil fertilization test, the following results have been obtained for reference.
