不同品系的胶树反复用10％的乙烯利进行刺激,每隔两个月刺激一次,历时3—9年,采用半螺旋线隔日刈或半螺旋隔五日刈制。胶树的反应是产量下降。本文研究与产量下降有关的生理方面和解剖方面的变化。测定的项目有胶乳产量,排胶速率,乳管组织的膨压,底层胶乳的稳定性,叶片色素的数量以及树皮和胶孔的养分水平,测定的对照树刈制采用半螺旋线隔日刈,刺激树是采用半螺旋线隔日刈和隔五日刈。
The gum trees of different strains were repeatedly stimulated with 10% ethephon and stimulated once every two months for 3 to 9 years using semi-spiral mulching or semi-spiral mulching for 5 days. Gum tree’s reaction is the decline in production. This article studies physiological and anatomic changes associated with declining production. The measured items were latex yield, discharge rate, turgor pressure in the tissue of the breast tube, stability of the bottom latex, the amount of pigment in the leaves, and the nutrient level in the bark and the gel hole. The control trees were milled by semi-spiral mulching , Stimulate the tree is the use of semi-spiral mulberry every other day and five-day mowing.
