What conditions are needed for longan cultivation
Longan is a common tropical and subtropical fruit. It has relatively high nutritional value, and after being dried it is called guiyuan (longan aril), which can be used in medicine. It has a good nourishing and tonifying effect, benefits the heart and spleen, and replenishes qi and blood. Its effects are powerful, and it is a fruit with relatively high economic value. So what conditions are needed to grow longan? Let's take a look together.
1. Temperature requirements
Longan is suitable for growing in warm climatic conditions. It can grow normally in any area where there is no frost in winter or only brief light frost. Its average annual suitable growth temperature is 21-23 degrees, and in January the temperature is 12-16 degrees. In winter it cannot be lower than minus 1 degree. If the temperature is lower than 0 degrees, its seedlings will be frozen and easily die. When the temperature is lower than minus 4 degrees, adult plants will also suffer varying degrees of freeze damage. Therefore, before planting longan, first check whether the local temperature meets what it needs for growth.
2. Soil requirements
Longan has no strict requirements for soil. It can also grow normally in barren, dry, and acidic goose soil, but if the plot has sandy loam on the surface and clay at the bottom layer, when longan is planted, the plants will have a shorter lifespan and lower yield, resulting in poor economic returns. Longan is suitable for planting in soil with deep soil layers, loose texture, good drainage, and good permeability. Before planting, the soil can be plowed and organic fertilizer applied as base fertilizer, so that longan can grow better and have a very high yield.
3. Water requirements
Longan is a fruit tree that likes moisture and tolerates drought, but it fears waterlogging. Throughout its growth period, its water requirements differ at each growth stage. From autumn shoots to spring shoots, its water requirement is relatively low. Only in this way can it avoid sprouting winter shoots, accumulate more nutrients, and help flower bud differentiation and flowering and fruiting the following year. In summer, in July-August, its water requirement is greater. If there is a lack of water during this period, it will affect the growth of the root system and branches and shoots, thereby affecting yield and quality. When the fruit is about to mature, the water requirement is also very high. Prolonged drought followed by sudden rain and prolonged rain followed by sudden drought can both cause fruit cracking and fruit drop, so water regulation must be done well.
