为了弄清椰子苗特别是在易发生旋风的沙地上的最适定植深度,1961年在Veppankulam椰子研究站布置了一个试验,据1967年报道,初步结果表明,植深60厘米的椰子苗生势明显旺盛。该站1974年明确指出,就植株始果期,根颈茎围和主要根数的观察结果来看,椰子苗栽植的最适深度为60厘米。自从1961年开展试验以来,1977年11月12日旋风首次袭击该地区,正是这次旋风,才取得了试验目的所探求的结果。本文讨论了不同种植深度椰子树的抗旋风能
In 1961, a test was conducted at the Veppankulam Coconut Research Station in order to understand the optimum planting depth of coconut seedlings on whirlwind-prone sandy land. According to a report in 1967, initial results showed that the coconut seedlings planted at a depth of 60 cm were exposed Obviously strong. The station in 1974 made it clear that the beginning of the plant period, the root circumference of the neck circumference and the main root number of observations, coconut seedling planting optimum depth of 60 cm. Since the experiment was carried out in 1961, it was this cyclone that struck the area for the first time in a cyclone on November 12, 1977, before the results of the experiment were obtained. This article discusses the anti-cyclone energy of coconut trees at different planting depths
