中文摘要：

采用田间试验研究了4种遮光处理及猪粪和化肥配施方式对石蒜切花产量和品质的影响。结果表明：遮光和施肥均显著影响石蒜切花的产量。适度遮光（遮光30％～65％）有助于提高石蒜切花的产量和品质。施用一定量有机肥可以提高石蒜切花的产量，以0．3m。施用1．3kg猪粪处理的花葶数最多；但是施用有机肥对提高品质没有明显作用。施用化肥可以使石蒜切花的花葶长度增长，单葶花朵数增加，花葶直径增大，花葶基粗增粗；加倍施用磷肥对改善石蒜切花品质没有明显作用。化肥配施一定量的有机肥既可以提高石蒜切花的产量又可以改善切花的品质。

英文摘要：

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.
