实践证明,在一定的刺激强度与采胶强度配合下,成龄芽接树针刺采胶产量可以超过常规刀割或接近刺激刀割的产量水平;在分析影响针刺采胶产量的因子中,发现采胶强度对针刺采胶的调节能力比刺激强度来得明显而稳妥。在理论上,针刺采胶树的胶乳糖含量明显地受刺激强度和采胶强度所制约。通常,糖含量以1.5毫克/毫升左右为好。统计分析表明,刺激强度和采胶强度与总糖含量呈负相关,与总酸量、电导率和无机离子含量呈正相关;而在一定的范围内,与产量也呈正相关。 1973年Tupy提出了针刺采胶的可能性后,引起了世界各主要产胶国家的高度重视。近年来,国内外不断加强对这项新技术的研究,取得了一定的进展。但它仍处于试验阶段,不少生产技术措施还不完善,其基本理论也不成熟。为了探索不同的采胶制度对针刺采胶的产量及其代谢活动的影响,我们从1977年开始对不同的采胶强度和刺激强度进行了研究,现将三年的试验结果初报如下。 Practice has proved that in a certain degree of stimulation intensity and the plasticity with the harvest, adult shoots acacia plastic seed production can exceed the conventional knife or close to stimulate the production of cutting knife; in analyzing the factors that affect the acupuncture production, It was found that the plasticizing strength of the acupuncture plastic digging ability than the stimulus intensity is obvious and secure. In theory, the gum acacia gum gum content was significantly stimulated by the intensity and the acquisition of plastic constraints. In general, sugar content of about 1.5 mg / ml is better. Statistical analysis showed that there was a negative correlation between stimulus intensity and plasticity and total sugar content, and positively correlated with total acidity, conductivity and inorganic ion content. In a certain range, it was also positively correlated with the yield. Tupy put forward in 1973 the possibility of acupuncture mining, causing the world’s major rubber producing countries attach great importance. In recent years, domestic and foreign countries have continuously strengthened their research on this new technology and made some progress. However, it is still in the experimental stage. Many technical measures for production are not perfect yet, and its basic theory is not yet mature. In order to explore the influence of different extraction systems on the yield and metabolic activity of acupuncture, we studied on different extraction and stimulation intensities from 1977. The results of the three-year trial are as follows.
