Embodiment

[0010] 1. Plastic surgery: the pruning of sweet-scented osmanthus and chestnut trees is divided into winter pruning and summer pruning. Winter pruning is to cut off part of the annual branches, that is, the opposite branches, light branches and inner slender branches are removed from the base; summer pruning is when the new shoots grow When it reaches 30 cm, the top of the new shoot is removed, the purpose is to promote the growth of branches and result in early results.

[0011] 2. Properly planting pollination trees is a prerequisite for high yields. Osmanthus Chestnut trees mainly rely on wind to disperse pollen. However, due to the phenomenon of heterosexual flower maturation and self-fertilization of chestnut trees, a single variety often produces empty buds due to poor pollination. Therefore, 15% of the pollinating trees must be planted in the newly-built chestnut orchard. The summer red chestnuts are used as the pollinating trees and the sweet-scented osmanthus chestnut ...

Abstract

The invention discloses a method for cultivating a sweet osmanthus fragrant chestnut tree, belonging to the technical field of cultivation of fruit trees. The method disclosed by the invention is a growing method summarized in the process of growing the sweet osmanthus fragrant chestnut tree for many years. Practice examination proves that the method has a good effect. In the event of growing the sweet osmanthus fragrant chestnut trees in large areas, sweet osmanthus fragrant chestnuts can be produced through the steps of selecting a land, selecting strong seedlings, applying enough base fertilizer, reforming, planting pollinizer in a matched manner, thinning flowers, thinning fruits, preventing and curing plant diseases and insect pests, harvesting in time and the like. The variety is one of the good varieties of chestnuts. The average weight of single chestnut is 12 g. The chestnut shell is dark purple and enriched in gloss. The flesh is yellow and tastes sweet and soft and has cinnamyl alcohol fragrance.
