对椰子根萎蔫病已做了大量的研究工作,但迄今尚无有效的防治措施。此病在十九世纪下半期初次出现,现已在印度喀拉拉邦蔓延达椰子种植面积的30％以上,给很多小椰农造成了相当大的经济损失。此病的特有症状显现在树冠和根系上。研究证明,排水不良是椰子根萎蔫病的一个主要原因。在无有效防治措施的情况下,若将病株复壮,从而降低减产速度,就会使椰农满意,但须有经济可行的办法实行这种复壮。为此,进 A great deal of research has been done on coconut root wilt disease, but so far there is no effective prevention and cure measure. The disease first appeared in the second half of the nineteenth century and has now spread over 30% of the coconut plantation area in Kerala, India, causing considerable economic losses to many small coconuts. The specific symptoms of the disease appear in the crown and root system. Studies have shown that poor drainage is a major cause of coconut root wilting disease. In the absence of any effective prevention and control measures, coconut farmers will be satisfied if they rejuvenate their plants and thus reduce the rate of reduction. However, there must be an economically feasible approach to implementing such rejuvenation. To do this, enter
