| The influence of formula fertilization optimization on dry rubber yield and economic benefits of the rubber plantation in Hainan Longjiang farm were studied by using “contrast”design method of fertilizer field experiments. The results showed that the actual production rate reached 4.61%, and the net production rate of dry rubber reached 3.97% by treating on formula fertilization optimization.Analysis of variance showed that the average dry rubber yield in Optimization of formula fertilization area was significantly higher than that of conventional area. And the results also indicated that the optimization of formula fertilization had obvious economic benefits, each rubber tree reduced cost and increased 9.95 Yuan on average after the test. |
