摘要
调查了海南省2004/2005年冬春期间低温对腰果树花穗、叶片、枝梢、嫩果实的影响,结果表明3次降温对腰果幼龄、成龄实生树和无性系树的花穗和膨大初、中期的果实都造成严重的寒害,叶片、枝梢受不同程度的寒害影响。发现抚管良好的腰果幼龄、成龄实生树和无性系树比管理不善的腰果树耐寒。根据调查结果,提出了提高海南腰果树耐寒力和腰果园经济效益的管理措施和建议。
An attempt was made during the winter and spring of 2004～2005 to investigate the effect of low temperature on the inflorescence, leaves, shoots and young fruits of cashew planted in Hainan. Results showed that the three times of low temperature caused serious damage to the inflorescences and the fruits at the initial and middle enlarging stage of young groves, mature seedling groves and clonal groves, and the leaves and shoots were damaged in different degrees. The young groves, mature seedling groves and clonal groves good management were found much more cold tolerant than those under poor management. Suggestions on agronomical practices and management are put forward to improve the cold tolerance and economic benefits of the cashew groves in Hainan based on the investigation.
