Microirrigation affects growth and root distribution of trees in fabric containers |
HortTechnology 4 (1): 43-45 |
Lagerstroemia x 'Natchez' ('Natchez' crape myrtle) crown width increased after 13 months as irrigation frequency increased from every 3 days to every day, and irrigated area around the fabric container increased from 20% to 100% beyond the container. Restricting irrigation to within the fabric container plus 20% of the area 20 cm beyond the container edge resulted in reduced height and width for crape myrtle, but not root growth, compared to irrigating 100% of area 20cm beyond the container. Restricting the pattern of irrigation to the container plus 20% of the area 20 cm beyond the container resulted in increased fine root weight (roots less than 5 mm diameter) within the container for laurel oak (Quercus laurifolia) compared to irrigating the container plus 100% of the area 20 cm beyond the container. Height, width and caliper of oak were not different among treatments. |
