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.
