EFFECTS OF SHADING LEVEL AND FERTILIZATION ON THE YIELD AND QUALITY OF LYCORIS RADIATA CUT FLOWER
摘要
Abstract
A field experiment designed to have different organic/inorganic combinations in fertilization and 4 levels of shading was carried out to study effects of fertilization and shading on yield and quality of cut flower of Lycoris radiata. Results show that shading and fertilization significantly affected yield of the cut flower yield. Proper shading (30% ,65% ) could improve yield and quality of the cut flower,and a higher level (90% ) of shading could also have a little effect in improving the yield and quality of Lycoris radiata cut flower in summer high in temperature and solar irradiation. Application of a certain amount of organic fertilizer could increase the yield of Lycoris radiata cut flower, but had no significant effect on quality of the cut flower. The treatment with 1.3 kg of pig manure only was the highest in yield in the experiment. Application of inorganic fertilizer could prolong scape of the flower, increase the number of flower per scape, and enlarge the scape in diameter and base diameter,but do nothing on yield of the flower in this study. However,increased application of P did not have any significant effect on improving quality of the cut flower. Treatment A2B2C1 (combining the three factors, shading, application of organic fertilizer and application of inorganic fertilizer) was highest in high in this study, averaging 25. 6 cut flowers per plot and 85. 57% in blossom rate. However, sharp variation was observed between the treatments in quality parameters of Lycoris radiata cut flower,which demonstrates that proper combination of inorganic fertilizer and organic manure in fertilization plus proper shading can increase yield of the cutflower of Lycoris radiata and improve its quality.关键词
