- Abstract:
- The Betel Nuts are located at Ta-Kan in Taichung, central Taiwan.The results obtained are summarized as following:(1)According to classification, the Betel Nuts root system is shallow root system.And the number of roots concentrate in 50 cm, top of soil.The diameter of roots are from 0.1 mm to 20.5 mm, and decrease with depth of soil.Apparently, roots system of the Betel Nuts has no main roots.The type of roots is classified as "Massive type".(2)According to measurement, fine roots and small roots have the highest proportion of the roots system.It is confirmed that the strength of roots of the Betel Nuts will be reduced because of that.(3)Densities of roots of the Betel Nuts distribute from 2.403×10-4 to 9.791×10-4 for samples.The densities of roots in downhill are higher from 1.2 times to 2.7 times than in uphill.
