Because traditional fertilizer, in the tobacco hole plate grows seedlings in the process to have Yi Shaomiao, high disappearing, to apply fertilizer many times and so on questions, this experiment take blank processing as well as the employment ordinary compound fat as the comparison, in the tobacco direct seeding grows seedlings in the process to employ controls differently releases the time and the different employment quantity controls releases compound fat, and to the smoke seedling's germination percentage, high, the stem thick, the dry wet weight, the chlorophyll content and so on main physiological growth target has conducted the research, is for the purpose of exploring controls releases compound fat, in the tobacco direct seeding grows seedlings the application effect, fertilizer being suitable to control releases the time, the suitable amount used. Discovered through the experiment: The employment controlled releases replaces ordinary fat compound carries on the flue-cured tobacco to grow seedlings fat the production to simplify the smoke seedling topdressing link, the labor saving reduced effort, to reduce the growing seedlings cost, because has prevented the smoke seedling ataxia phenomenon which effectively the topdressing caused non-uniform, enhanced the smoke seedling degree of uniformity and grows seedlings the quality; Achieved reduced the fertilizer in the production to lose, the protection ecological environment as well as the release and the absorption synchronization goal. the topical glossary (according to arranged in order) the tobacco hole plate direct seeding has grown seedlings (tabacco plug seedling) to burn the seedling, wilting (wilting) blank processing (blank test) controls releases compound fat (controlled-release fertilizer) ordinary compound fat (common compound fertilizers) the germination percentage (Seeding Emergencerate), high (Shoot height), stem thick (Stem diameter), dry weight (dry weight), leaf area (Leaf area), wet weight (humid weight), strong sprout index (Sound Seedling Index) chlorophyll content (Chlorophyll content) physiology growth target(physiological index and growth target) controls releases the employment quantity which the time (controlled-release time) is suitable (optimum dosage) the topdressing (refertilize) the labor saving (laborsaving) the growing seedlings cost (seedling cost) the degree of uniformity (uniformity)

Abstract
Fertilizers as a result of the traditional plug of tobacco seedlings in the course of the existence of burnability Miao, high loss, fertilizer and other issues to be repeated, the experiment in order to deal with as well as the use of ordinary blank as a control compound, live in tobacco seedlings of different controlled-release application process time and different application amount of the controlled-release fertilizer, and seedling germination rate, plant height, stem diameter, dry weight, chlorophyll content and other key physiological indicators of growth have been studied to explore the controlled-release fertilizer live in tobacco seedlings Application effects of controlled-release fertilizer suitable period, the appropriate dosage.
Found by experiment: application of controlled-release fertilizer to replace the ordinary compound reduced the production of flue-cured tobacco seedling nursery topdressing links, saving labor, reducing breeding costs, to effectively prevent non-uniform because of top-dressing phenomenon caused by irregular seedling and improve seedling uniformity and seedling quality; to achieve reduction in the production of fertilizer loss, protect the ecological environment as well as the release and absorption of the purpose of synchronization.

due to the traditional d'engrais in tobacco seed in the process of calcination seedlings, with high emissions, multiple fertilization issues such as this experiment with a blank application processing as well as for ordinary fertilizer in tobacco control, direct seeding nursery in the process of applying different release time and different application - release fertilizer and on bemisia tummor huperna, adenophorum, micoorganisms high crude, heavy, wet and dry chlorophyll content such as the main physiological growth index, aimed at exploring the live - release fertilizer in the tobacco seedling effect, d'engrais lenditself, lenditself dosase - release period.through experimental reveals： applyingthe - release fertilizers instead of ordinary fertilizer for flue - cured tobacco seedling production reduces the tobacco seedling topdressing faches, wojewodztwo indrutry, reducing the effort to prevent seedling cost through topdressing UN-uniform bemisia propagaption of the result of the phenomenon of inequality, improving the tobacco seedling nursery uniformity and quality; in the production reached d'engrais for loss, reducing the protection of ecological environment and the release and uptake of synchronization.Glossary (alphabeticalorder) has been adjusted for tobacco (plug direct seeding nursery tabacco plug seedling) yakeishi of propagaption, wilt (wilting) blank (blank test) - release fertilizer fertilizer (controlled-release) ordinary fertilizer compound fertilizers (common) huperna (emergencerate), seeding plant height (ã²áo), � shoot stem diameter stem diameter), (dry weight (dry weight) leaf, leaf area (area), wet weight (weight), humid Rolfe index (index) sound seedling chlorophy (chlorophyll content) physiological growth index (index and physiological growth target (controlled-release) - release time to time) the most suitable fertilizer (optimum dosage) top dressing (refertilize) wojewodztwo indrutry (laborsaving) seedling nursery cost (cost) uniformity (uniformity)
