施用微量元素對綠蘆筍嫩莖葉綠素形成之影響研究

陳榮五

摘  要

本文研究施用微量元素及不同畦向對葉綠素之形成研究,其結果為:

(一)微量元素對嫩莖葉綠素之形成並無明顯效果(土壤pH6.2∼6.5)。

(二)畦向對嫩莖葉綠素之形成有關而以南北畦向之含量高於東西畦向。

(三)依時期來說,則以11月份及4月份溫度較低時,葉綠素含量較高溫度較高之6月份,葉綠素含量則較低,此因溫度較高,生長較快之故。


Studies on the Effect of Minor Elements in the Chlorophyll Formation in Green Asparagus

J. W. Chen

Summary

        The studies were on effect of minor elements application and different row direction in the chlorophyll formation in green asparagus.

        Results indicated that: (1) There was no significant efficiency for chlorophyll formation with minor elements application. (Soil pH value 6.2~6.5). (2) It was obvious that row direction was considered significantly in determining the chlorophyll formation, the chlorophyll content of spears harvested from the rows for north-south direction were higher than those from the rows of west-east direction.  (3) The chlorophyll content of spears harvested was higher in November (temperature 25~30℃) and April (temperature 20~28℃) than that of spears harvested in June (temperature above 30℃).  Particularly, it was highest in November.  The reason is due to the spears growing very rapidly during the high temperature (above 30℃), in this case the chlorophyll content would be low, and the period of spears harvested in November (temperature 25~30℃) were suitable for the chlorophyll formation so that the chlorophyll content would become high.
