Abstract:

In order to systematically study the matrix field planting seedlings of light lacquer technique, with four factors, three-level orthogonal design, the effects of the time interval by fertilization, nitrogen, phosphorus and potassium fertilizer on the seedling high, to stem, root to shoot ratio, seedling index were studied. The results showed that: Fertilization interval of height, to stem, root to shoot ratio, seedling index had a very significant impact, urea, superphosphate, potassium chloride on the use of seedling height, ground stems, seedling index had significant effects, while urea, superphosphate, potassium chloride, the use of the impact of root to shoot ratio was not significant. The process of fertilization in the nursery, fertilization more frequently, the higher the height, to the more coarse stems, shoot and seedling index the greater the interval of fertilization and the best time and best fertilizer. The simulation optimization, optimal fertilization program was added to the water when 100 kg of urea, superphosphate, potassium chloride, respectively 0.826, 2.122, 1.696 kg, once every nine days pouring a times to seedlings, this fertilization was the best.
