以马蹄荷播种苗为试材,在黄心土和肥沃表土2种基质上育苗,施用浓度为0.5%的高氮型、高氮高钾型、高氮高磷型和普通型4种类型混合肥,研究不同基质条件下施肥对1年生苗木高度和地径生长的影响。结果表明:不同基质条件下的N、P、K施肥处理,对马蹄荷播种苗的苗高和地径生长均有极显著的促进作用。在比较贫瘠的黄心土基质上培育马蹄荷苗木以N、P、K比较均衡的施肥配方效果最佳,且应适当增加施肥浓度或施肥次数以提高苗木生长量;而在肥沃表土基质上则以N和K比例较高的施肥配方效果最佳。
In this study, seedlings of Himalayan sowing seedlings were used as test materials, and seedlings were nurtured on two substrates of yellow hearth soil and fertile topsoil. Four kinds of high-nitrogen, high-nitrogen and high-potassium, The effects of fertilization on the height and diameter growth of 1-year-old seedlings under different substrate conditions were studied. The results showed that N, P and K fertilizers under different substrate conditions promoted the seedling height and diameter growth significantly. In the relatively poor soil of yellow heart soil nurturing Horseshoe seedlings to N, P, K more balanced fertilization formula best, and should be appropriate to increase the fertilization concentration or number of fertilization to increase the growth of seedlings; and fertile topsoil matrix N And K proportion of high fertilization formula best.
