| Abstract: | Tung oil is employed as a coating material to produce coated-released-fertilizer.The velocity of release of nutrient with the coated urea in greenhouse soil-less culture is studied in this paper.The experiment of the tobacco in greenhouse soil-less culture is carried out to examine the utilization ratio of the nitrogen in coated-released-fertilizer.It is made clear through the results that nutrients released from coated-released-urea is 59.6% lower and that the utilization ratio of coated-released-urea is 10.8% higher than those of normal urea respectively in day 1.It is then concluded that tung oil coated urea is good in nutrients release and utilization. |
