Proper flower and fruit management during longan cultivation
1) Releasing bees for pollination. Longan is a dichogamous insect- and wind-pollinated flower, mainly pollinated by insects. Bees are most active within a radius of 250 m, so bee colonies are best kept dispersed throughout the orchard. For every 0.46-0.53 sq km of longan orchard, one bee colony (8-10 hives) should be provided.

Key Points of Fertilizer and Water Management Techniques for Longan Cultivation
Scientific fertilization based on the growth characteristics of longan and the requirements of its annual growth cycle is the foundation for early fruiting, high yield, and premium quality in longan trees. Experiments have proven that a longan orchard producing 1 ton of fruit per mu should apply 20-25 kg of pure nitrogen annually (of which organic fertilizer nitrogen accounts for about 40% of the annual nitrogen application). Nitrogen

Pineapple Cultivation: Methods for Managing Sucker Removal and Retention
(1) Removing the crown bud When the crown bud reaches about 20 cm tall, its upper part opens out and its base narrows. When young roots appear at the leaf base, which is what is called "spreading tail and gripping waist," the crown bud can be twisted off by hand in a clockwise direction to be used as planting material, which fruit growers call "topping." Topping is generally carried out from late May to June.
