三种低频割制对胶乳生理特性、产量及生胶质量的影响
Effects of Three Low-frequency Tapping Regimes on Physiological Characteristics of Latex,Yield,and Raw Rubber Quality
摘要
Abstract
To evaluate and select low-frequency tapping systems suitable for actual production and achieve the synergistic improvement of yield and quality of natural rubber,this study took the Reyan 73397 rubber tree as the material,adopted a randomized block design,and set up three types of low-frequency tapping systems:tapping once every three days(d3),once every four days(d4),and once every five days(d5)to investigate their impacts on the latex physiological characteristics,raw rubber quality,and yield of rubber trees.The results showed that the d4 tapping system had the highest latex total solid content and a relatively high sucrose content,which was beneficial for material accumulation and carbon metabolism.The d5 tapping system had a higher weight-average molecular weight and number-average molecular weight of raw rubber,with the smallest molecular weight distribution coefficient,showing advantages in processing performance and the physical-mechanical proper-ties.The fresh latex yield and dry rubber yield of the d4 tapping system were significantly higher than those of the d5 tapping system,and the dry rubber yield per tree per tapping was approximately 29.45%higher than that of the d3 tapping system.Overall,the d4 tapping system performed relatively well in terms of yield,latex physiological characteristics,and raw rubber quality.The research results provide theoretical and technical support for optimizing the tapping plan and coordinately im-proving the yield and quality in the natural rubber industry.关键词
