【摘要】 小苍兰切花的出花率低,是由于种球染病,造成较高的缺株率和枯株率,并使花茎长度达不到市场规格的要求,从而影响了栽培生产的经济效益。克服的途径,拟于栽种前剔除病球,进行种球消毒、换土与土壤消毒等。实践证明这些措施是可行的,可使小苍兰复壮,保持切花的优质高产,具有高度的经济效益。更多还原

【Abstract】 The lowering economical profits of Freesia cut flower production are due to the decreasing of the percentage of flower formation and the length of flower stems. The high percentage of seriously damaged plants by diseases during the growing period and the disease contaminated mother corms arc the main causcs. Also the decreasing of the length of flower stems are caused ty the different degree of disease contaminated mother corms. Assuming that by picked off the diseased corms, the sterilization of corms, soil exchange or sterilization may decrease the disease contaminating, and promote the production and quality of cut flower. After several years of experimentation the hypothesis has been demonstrated the percentage of flower formation and the length of flower stems increased obviously. To apply these practices in Freesia tcut flower production with te production of virus free corms may get a high econo cmical benifit.更多还原
