The weather changes greatly in spring. What are the key points for lychee management?

The first priority for lychees in spring is to preserve flowers and fruits. In years with good weather, it is easy to preserve fruits. However, in most years, female flowers bloom in lychees, often due to cold spells and continuous rain, which can easily lead to retting and finally flowers but no fruits. In some years, extreme drought and high temperatures occur when lychee flowers bloom. Improper management can also cause this. Ammonium nitrogen compound fertilizer is beneficial to be absorbed by the soil and is not easily lost. It is not affected by low temperatures and has a high utilization rate. It is used as an organic fertilizer for farmers. It is best to mix the fertilizer together and apply it as a base fertilizer.

When lychees are harvested, many branches will be broken and bruised, resulting in a mess on the ground. At this time, some fallen leaves, garbage and dirt need to be cleaned up in time. It is best to take them out of the orchard. Burn the lychee trees to prevent them from being infected by pathogens and affecting the growth of the lychee trees. In addition, it is necessary to prune off dense inner branches, leggy branches on the main branches and other branches that will affect next year's fruit setting. As for these pathogenic habitats and plant consumption organs, early removal will provide an early guarantee for a high yield of fruit trees in the coming year.

Apply emergency fertilizer, which means that the lychee plant consumes a lot of nutrients when the lychee grows and matures, and it needs to be quickly added back to restore the vigorous growth of the lychee tree. Mainly compound fertilizer. Trees with little or no fruit and vigorous growth can be pruned again. Especially trees without fruit should be pruned appropriately. Trees with empty flowers can be pruned after the flowers fade in spring. Trees with a lot of fruit should be pruned after harvesting in autumn. Prune when the shoots sprout; for weak trees with many fruits and few leaves, they should be pruned after the shoots mature in the first autumn.

If we leave it alone after picking, the orchard will not be able to achieve high yields next year, which will cause our fruit farmers to lose a lot of economic benefits. Therefore, in order to ensure that they can produce stably in the coming year, we must manage the orchard after harvesting. The most important step in the process of planting them is that weak trees and weeds will inevitably compete for nutrients. Therefore, weeding is required. Do not throw away the grass. The removed weeds should be buried near the root system of the lychee tree. , after 2-3 months of rotting weeds contain higher nitrogen fertilizer and other nutrients.
