In a general view on the perimeter of harvested bulbs and disease control, this year was better than previous. Growth medium had significant influence on the survival rate of seedlings, bulb perimeter, single bulb and total fresh weight. Amendment of sugar-cane sewage compost in soil was attributed to lowering seedling mortality and to enhancing bulb growth. Sugarcane sewage compost and the soil in Wan-Hsing Farm mixed by 1:1 ratio was helpful in increasing the bulb size; however, if mixed by 1:4, it would augment the colonization of Rhizoctonia sp. in lily roots. Bulb scale could be embedded individually in a plastic bag with vermiculite and pearlite to enforce bulblet production. Single scale packing method was better than traditional group packing in laborsaving and high yield of bulblet production. Glomus intraradices inoculated at this treatment could ensure higher VA colonization of lily in the field. Nevertheless, in the same enforcing treatment, fertilizer amendment could diminish root colonization, especially after bulblets were transplanted to the field. Bulblets infected by G. intraradices could stem out fast two weeks after planting and to 5.5cm height in average. The harvested bulbs after biocide and none-fertilizer treatment were large up to 14 cm in perimeter, and 8.8 cm/bulb in average. Entrophospora kentinensis was more tolerate to the fertilizer amendment than G. intraradices. Through a dilution test to evaluate the effect of sugarcane-sewage compost on the bulb growth, the ratio of compost was closely related to the VA inoculation effect. The more compost was the less inoculation effect. If compared VA colonized zones with non-VA colonized zones, the incidence of Rhizoctonia in the former location was much lower than the latter. This implied that VA mycorrhizal fungi exerted its potentiality in the biocontrol of soil-borne pathogen, such as Rhizoctonia. |
