橡胶园优化施肥配方在海南龙江农场应用的经济效益分析

摘要

采用“对比”方法设计肥料田间试验研究了优化配方施肥对海南龙江农场橡胶园干胶产量及其经济效益的影响。结果表明，与常规施肥处理相比，优化配方施肥区橡胶树的平均干胶产量显著高于常规施肥区，优化配方施肥区实际增产率达4.61%，干胶净增产率达3.97%。结果同时表明，优化配方施肥处理产生的经济效益明显，试验后每株橡胶树平均节本增效9.95元。%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 application of optimized fertilization formula. Analysis of variance showed that the average dry rubber yield in optimization of formula fertil-ization area was significantly higher than that of conventional area. The results also indicated that the optimization of formula fertilization had obvious economic benefits, and each rubber tree reduced cost and increased 9.95 yuan on average after the test.
