橡胶树1龄苗的解剖学和生理学的特性与其成龄期产量有关。为了弄清两者间的相互关系,我们从1978—1983年进行了研究。本文就研究结果作一简述。一、试验材料和方法试验材料为本院预测苗圃的1龄苗。株行距为0.4×1米。样株生势健壮,顶蓬叶稳定。测定的叶部指标均采顶蓬的下一蓬叶。
The anatomical and physiological characteristics of 1-year-old seedlings of rubber trees are related to the yield of their mature adult. In order to understand the relationship between the two, we conducted a research from 1978 to 1983. This article gives a brief account of the findings. First, the test materials and methods Experimental materials for the hospital nursery 1-year-old seedlings. Line spacing of 0.4 × 1 m. Health-like potential strain, Ding Peng leaves stable. Measured leaf index are taken next Peng Ding Peng.
