摘　　要：以金煌芒果开花植株为试验对象,研究花穗不同短截时期、主花穗保留长度和侧穗保留数量等不同处理对芒果坐果效应和果实品质的影响。结果表明:于盛花初期短截花穗,主花穗保留3~5 cm,同时保留3~5条侧穗处理效果最佳,空枝率降至24.26%~29.11%,与对照相比降低了17.02%~30.84%;单果重447.87~470.93 g,单株产量86.07~89.07 kg,与对照相比分别提高了50.09%~57.82%和40.32%~45.21%。研究表明,开展短截花穗处理能有效促进挂果,减少植株空枝率,提高单果重和单株产量。By taking mango variety‘Jinhuang’flowering plant as experimental material,this paper dealed with the fruit setting and fruit quality effect of different times of floral cluster short-cutting,main flower spike retention length and number of flower spike lateral branches.Results showed that it can make the empty branch rate reach 24.26%~29.11%,the average fruit weight to 447.87~470.93 g and yield per plant to 86.07~89.07 kg,with decreasing 17.02%~30.84%while increasing by 50.09%~57.82%and 40.32%~45.21%compared with the control respectively in the condition of short-cutting floral cluster at the early stage of flowering,maintaining the 3~5 cm length of the main flowers and keeping 3~5 flower spike lateral branches.The results suggested that floral cluster short-cutting can effectively promote fruit hanging,reduce plant empty branch rate,and also increase fruit weight and yield per plant.
