Postharvest management of bayberry must keep up with it.

The nutritional status of bayberry plant directly affects its yield, quality and tree potential. In order to make the high yield and bumper harvest of red bayberry in the following year, overcome the phenomenon of fruit in the next year, and make the bayberry trees have good autumn shoots, the following management measures should be taken in time after fruit harvest.

Scientific fertilization: the autumn shoot of red bayberry in that year is the effective fruit mother branch of the red bayberry plant in the following year, so autumn shoot fertilizer should be applied within 15-20 days after fruit harvesting, and the amount of fertilizer should depend on the tree strength and fruit yield. the plant produces more than 50 kg of trees, 40-50 kg of organic fertilizer, 1 kg of phosphate fertilizer and 0.5 kg of mixed urea, and the soil is covered with 20-25 kg of rice straw after fertilization. Generally use ditch application method, in the crown dripping line to dig 30-40 cm deep ditch fertilization, do not put fertilizer into the tree plate, in order to avoid failure. Reasonable pruning: while fertilizing the bayberry tree, it can be combined with reasonable pruning of the branches, removing disease and insect branches, weak branches, withered branches and shade branches, and properly opening the skylight, so as to make the crown ventilated and transparent, produce more autumn shoots, and improve the quality of autumn shoots. Reduce the range of annual fruit. Sweep the fallen leaves: after picking the fruit, the bayberry tree should immediately do a good job in clearing the garden, sweeping the fallen leaves of the fruit tree and burying it deeply into the ground. In this way, on the one hand, it can loosen the soil, moisturize and cultivate trees, and on the other hand, it can reduce the harm of diseases and insect pests. Control of diseases and pests: leaf spot can be sprayed with 0.1-0.5 degree Bordeaux solution, or 1000 times carbendazim or chlorothalonil solution after fruit harvest, once every other week for 3 times. Caterpillars are generally hatched in an environment of more than 20 ℃. When a small number of caterpillars occur, they can be caught manually or trapped by lanterns; when a large number of caterpillars occur, they can be sprayed and killed by pesticides such as killing Suding or kung fu.
