Key points of cultivation

Proper close planting. Taoxi extra-early honey pomelo branch growth is more erect, appropriate close planting, general flat plant spacing of 4 meters x 5 meters, mountain 3.5 meters x 4.5 meters; reasonable pruning. Young trees are pruned to control the top growth and expand the crown. Summer shearing should use brace, pull branches, increase branch angle and adjust growth orientation, while spring shearing should focus on thinning the upright and vigorous long branches on the top and backbone branches. Shrinking pruning is often used in adult tree pruning to renew weak branches, control top growth, improve crown light conditions and increase fruit yield. Fertilizing and watering. Every year, emphasis is placed on strong fruit fertilizer and fruit picking fertilizer, which is applied from the end of June to early July, accounting for about 40% of the total amount of fertilizer applied in the whole year, mainly nitrogen, phosphorus and potassium fertilizer, combined with organic fertilizer. Fruit harvesting fertilizer must be applied before the middle and late October, mainly organic fertilizer, accounting for 50% of the annual fertilizer application, accounting for 50% of the total amount of fruit fertilizer. Spring fertilizer is applied according to the situation of the tree, whether it is weak or strong. The fruit should be irrigated in time in case of drought during fruit growth and ripening period. Thinning flowers and fruits. The flowering and fruiting rate of Taoxi extra-early honey pomelo is high. In order to improve fruit quality, enhance its commerciality and maintain a reasonable ratio of leaf to fruit, it is necessary to thinning flowers and fruits in time. Pest control. The main diseases and insect pests are canker, resin disease, red spider, scale, leaf moth and longicorn beetle. The main control methods should be to enhance the tree potential, improve resistance, improve tree ventilation and other production measures, combined with timely spraying control.
