An Assessment on the Adaptability of New Species Hemerocallis
[Abstract] Hemerocallis are characterized by rich design and color, strong adaptability, easy cultivation, simple maintenance and high ornamental value. Considering the current development and spread of domestic Hemerocallis are not good and fast enough, and the cost of import is expensive, this experiment sets several index, such as flower color, flower shape, flowering time, stem, leaf shape and plant type. On the basis of the principles of system, science, matching, relevance, maneuverability and reliability, this paper focuses on the assessment and selection of good Hemerocallis, which adapt for a variety of purposes, in order to provide a reference for the application and development of domestic garden Hemerocallis. This paper is mainly from following four points: first, to observe 36 kinds of unknown crossbred Hemerocallis in the experimental field of the Shanghai Institute of Technology and make table forms on 13 index; second, to make assessment standards on selected index and calculate the comprehensive scores of all Hemerocallis species; third, to selected the top five species of Hemerocallis according to the scores and confirm one as the best; and fourth, to selected 5 suitable Hemerocallis species for clump planting, 5 for group planting and 5 for isolated planting.
