Abstract:

In order to research influence of growth of the tobacco with coated compound fertilizer in soilless cultivation, with the new coating material as the Idesia polycarpa var. vestita oil and producing the coated-released-fertilizer, the method of pot cultivation experiment was used in the growth of tobacco. The result showed that the weight of fresh bio-mass of the tobacco was 657.8 g in coated-composite fertilizer and that was 513.5 g in composite fertilizer and that was increase 148.3 g in soilless agriculture, the quality of dry matter of production of per gram. Coated compound fertilizer was up to 6.1 g higher than ordinary composite fertilizer. The proof was tested that the coated-composite fertilizer as coating material with Idesia polycarpa var. vestita oil was good production.
