| 中文摘要: |
| 以长有两蓬叶的热研 7-33-97 橡胶芽接苗为材料，通过盆栽试验研究叶片喷施不同水平有机养分水溶液肥对橡胶苗生长的影响。结果表明：不同浓度有机养分水溶肥处理下，第一、二蓬叶 N、P、K、Ca 等养分含量显著高于清水对照组，且在 A2、A3 处理下达到最大值；不同浓度有机养分水溶肥处理下，橡胶苗株高增长量和茎围增加量显著高于清水对照组，且在 A2 处理下达到最大值；不同浓度有机养分水溶肥处理下，叶片叶绿素含量得到显著提高。 从生产成本和效果来看，A2 处理最适宜，且在第二蓬叶前喷施效果较好。 |

| Taking SCATC 7-33-97 as the experiment material, the effects of different levels of organic nutrients
fertilizer on the contents of N, P, K ,Ca and Mg in rubber budding leaves were studied. The results showed that the
contents of N, P, K, Ca in the first and second canopy leaves were significantly higher than those in water treatment
at different concentrations of organic nutrients, and reached their maximum at the treatment of A2 and A3. The
increase of plant height and stem circle reached significant effect at different concentrations of organic nutrients, and
reached their maximum at the treatment of A2. The content of chlorophyll in the leaves significantly increased at
different concentrations of organic nutrients. The treatment of A2 was most appropriate from the cost of production
and effect. And the effect was better before the second canopy leaves by foliar application. |
