Applying flower-promoting fertilizer to lychee around Minor Cold is the right time
(1) Increase the application of organic fertilizer and avoid excessive use of chemical fertilizers. Based on a tree producing 50 kg of fruit, apply 0.5 kg of superphosphate, 1 kg of potassium sulfate, and about 10-15 kg of fully composted organic fertilizer per tree after flower drop, then apply manure water fertilizer once each at 35 days and 50 days after flower drop. (2) Timely and appropriate irrigation...

What are the technical measures for flower and fruit retention in lychee?
1. Strengthening flowers and retaining flowers. (1) Apply flower-strengthening fertilizer in time. Flower-strengthening fertilizer is generally applied when the flower panicle emerges and flower buds are visible (also called fertilizing at flowering). The amount applied depends on the number of flowers formed and tree vigor; generally, for every 50 kg of fruit produced by the tree, apply 1 kg of compound fertilizer plus 0.2-0.5 kg of urea, or apply 0.5 kg each of urea, superphosphate, and potassium chloride....

How to Conserve Flowers and Fruits in Lychee? Detailed Explanation of Key Technical Measures
1. Strengthening flowers and conserving flowers. (1) Apply flower-strengthening fertilizer in time. Flower-strengthening fertilizer is generally applied when the flower spikes emerge and flower buds are visible (also called fertilizing at flowering). The amount applied depends on the number of flowers formed and the tree vigor. Generally, for every 50 kg of fruit produced by the tree canopy, apply 1 kg of compound fertilizer plus 0.2-0.5 kg of urea, or apply 0.5 kg each of urea, superphosphate and potassium chloride...

Detailed Explanation of Spring Management Measures and Technical Points for Lychee
China generally experiences dry climate, which promotes nutrient accumulation and flower bud differentiation in lychee and longan. It is currently spring, and lychee management during this season is a key link related to the quality of growth and development in the current year. Based on the current growth and development situation of lychee and longan, the following technical work opinions for spring management are specifically proposed. Lychee due to...

Key Technical Points for Fruit Retention and Fruit Enlargement in Lychee, Longan and Mango
At present, most lychee and longan trees in Guangdong Province are at the stage from flower panicle emergence to flower bud stage. Affected by the weather since the beginning of spring, with relatively high temperatures and suitable humidity, the flower panicles of lychee and longan have emerged early, pests and diseases have occurred early, and the base of pest and disease sources after winter is relatively high. It is expected that the main pests and diseases during the flowering period of lychee and longan will occur at a moderate level, with some areas being relatively severe. Lychee stink bug...

How to control dodder (Cuscuta) on lychee and longan
Dodder has no roots and no leaves, but its stem bears serrated haustoria (or sucking roots), which it uses to penetrate deep into the bark to absorb nutrients, affecting the growth of the fruit seedlings; in severe cases it can cause the seedlings to wither and die. It is more commonly seen in mature lychee orchards in mountainous areas. Dodder can flower and set seed; the flowers are small and white, and the fruit drops to the ground on its own after ripening...

Detailed Explanation of Key Points in Lychee Cultivation and Management Techniques
Lychee anthracnose is an important lychee disease. It damages young leaves, flower spikes and fruits. It causes a large number of rotten and fallen fruits during the lychee ripening period. [Symptoms] Leaf damage often starts at the leaf tip, initially producing round or irregular light brown small spots, which then rapidly expand into dark brown large spots with unclear edges. In...

How to remedy lychee trees after frost damage? A new method is here
Winter temperatures are relatively low and rainfall is relatively scarce, with low-temperature frost and freezing weather occurring frequently. This caused most lychee trees to suffer frost damage to varying degrees, and the top leaves were frozen and killed. Therefore, frost prevention work must be done promptly, and the specific measures are as follows: before the frost arrives, spray the entire orchard with New High Lipid Film to keep warm and prevent freezing...

How to Grow Lychee for High Yield? A Detailed Guide to Practical Cultivation Methods
Site selection and planting: For high-yield lychee cultivation, open terrain with loose, fertile soil, a deep soil layer, and a water source on hills or slopes should be chosen, as this is ideal for developing a planting orchard. Lychee mycorrhizae are aerobic, so the soil should be loosened, improved, and made porous and well aerated to promote root development. Soil fertilization should follow the principle of frequent light applications. Spray in a timely manner...

How to prevent lychee fruit cracking? Calcium application is an effective method
In recent years, lychee fruit cracking (in cultivars such as Nuomici, Guiwei, Sanyuehong, Lusha, and Tianyan) has become fairly common. Lychee fruit cracking mostly occurs during the fruit enlargement stage, generally at 20-30% in normal years, and reaching 50% in severe cases. There are many domestic reports on the causes and mechanisms of lychee fruit cracking, and many researchers have mentioned...
