采用单位面积和单株产量与劳动生产率相结合的相对经济效益评价方法,对橡胶树PR107中龄开割树5种不同的割胶制度——S/2 d/2、S/2 d/3+ET2.00％、S/2 d/4+ET2.50％、S/2d/5+ET3.00％、S/2 d/6+ET3.50％连续3 a的试验结果进行分析评价,结果表明:当割胶劳动报酬占产值的比例(Ⅰ值)在28％以下时,S/2 4t/3+ET是中龄PR107的最佳割制;当Ⅰ值超过29％时,其最佳割制为S/2 d/6+ET。此外,试验结果还表明,采用乙烯利刺激的4种割制涂药后,同一割次的产量无显著差异;不同割制间,对茎围生长、死皮停割树的增加等副性状的影响无显著差异。
Based on the relative economic evaluation method of unit area, yield per plant and labor productivity, five different kinds of rubber cutting systems, namely S / 2 d / 2, S / 2 d / 3 + ET2 The results of the test for 3 consecutive days were analyzed and evaluated with the results of the test, the results showed that the test results were as follows: .00%, S / 2 d / 4 + ET2.50%, S / 2d / 5 + ET3.00%, S / 2 d / 6 + ET3.50% : S / 2 4t / 3 + ET is the best cut of mid-age PR107 when the ratio of labor remuneration to output value (Ⅰ value) is less than 28%, and the best cut when I value exceeds 29% S / 2 d / 6 + ET. In addition, the test results also showed that ethephon-stimulated four kinds of cutting application, the same cutting times the yield of no significant difference; cutting between different cuttings on the growth of the stem circumference, cuttings and other dead-cut trees increase the secondary traits No significant difference in impact.
