Abstract

To study the effects of carbamide and KH2PO4 as fertilizer on leaf growth and bulb biomass of Lycoris haywardii over two successive growing seasons，an experiment with a two-factor design of four different carbamide and KH2PO4 application levels （carbamide at 0，0.5，1.0 and 1.5 kgm－2；KH2PO4 at 0，0.35，0.70 and 1.05 kgm－2） as a topdressing fertilizer and three repetitions was established. Data were analyzed with SSPS16.0. Results showed that carbamide applications （＞0.5 kgm－2） had a significant （P＜0.05） negative effect on leaf number，sprout number，bulb number and bulb biomass in the next growing season，and leaf length in the following growing season. The KH2PO4 treatment at 0.35 kgm－2 in the following growing season significantly increased the leaf count （P＜0.05）. Leaf quantity was linearly and positively related to the bulb biomass （linear regression；r=0.941，P=0.000） and was similar to qualitative results from subjective evaluations. So，subjective evaluation could be used to estimate live-weight trends for bulb biomass and to evaluate growth effects of L. haywardii with fertilization. ［Ch，8 tab. 10 ref.］
