连续三年(1977—1979)研究表明,在合理的刺激强度与采胶强度调控下,成龄芽接树针刺采胶产量可超过常规刀割或接近刺激刀割水平。由于刺激强度与采胶强度不同,在各采胶制度胶乳产量与总糖含量的关系上,基本上有三种类型:即高产低糖、低产高糖和高产高糖。长期保持高产高糖只有在特定的条件下才存在。通常,对针采而言,胶乳总糖含量以1.50毫克/毫升为宜,干胶含量以22％为宜。统计分析表明,刺激强度和采胶强度与总糖含量星负相关,与总酸量、电导率和无机离子含量呈正相关;在一定范围内,与产量呈正相关。
The results of three consecutive years (1977-1979) showed that under the control of reasonable stimulus intensity and harvesting intensity, the yield of plastic injection of tree-needled jatropha can exceed that of conventional or near-stimulated cutting. There are basically three types of latex production in relation to the total sugar content of the sealant system: high-yield and low-sugar, low-yield and high-sugar and high-yield and high-sugar. Long-term high-yielding sugar only exists under certain conditions. In general, needle acupuncture, the total sugar content of latex to 1.50 mg / ml is appropriate, dry content of 22% is appropriate. Statistical analysis showed that there was a negative correlation between stimulus intensity and plasticity and total sugar content, and positive correlation with total acidity, conductivity and inorganic ion content. Within a certain range, it was positively correlated with yield.
