Abstract
Numerous investigations into the effects of different types of fire on blackthorn were conducted. The basal stems of blackthorn were burned with a gas flame at soil level and 12 inches above soil level for periods of 1, 3 and 6 minutes respectively. An illustration of a “flame girdling” apparatus which was especially constructed for these investigations and a description of its operation, is presented. A total root kill of blackthorn was obtained by burning the lower basal stems of the plant for periods of 3 and 6 minutes respectively. All other burn treatments resulted in the development of coppice shoots. A fire‐mechanical method for eradicating blackthorn is suggested.
UITTREKSEL
Die invloed van verskillende metodes van brand op swarthaak is ondersoek. Die stamme van swarthaak is met ‘n gasvlam by grondoppervlakte en 12 duim bo grondvlak, vir periodes van. 1, 3 en 6 minute onder‐skeidelik, gebrand. ‘n Vlamomgordelingsapparaat wat spesiaal vir hierdie ondersoek ontwerp is, word aan‐gebied tesame met ‘n beskrywing van die werking daarvan. Algehele wortelvrekte by hierdie plant is verkry wanneer die onderstamdele van die plant vir periodes van, óf 3 óf 6 minute gebrand is. Al die. under brandbehandelings het tot die ontwikkeling van nuwe stamlote. gelei. ‘n Meganies‐vuur metode vir die uitroeiing van swarthaak is voorgestel.
