1. Management technology of Myrica rubra: It is necessary to prune some branches with poor growth conditions in time, such as old and weak branches, branches with diseases and insect pests, branches that are too long and too dense, dead branches, branches that mop the floor, etc., and at the same time, it is necessary to pay attention to protecting the tree body. It is necessary to get the snow off the branches in time after it snows, and it is necessary to choose appropriate chemicals to prevent and control diseases and insect pests. For example, brown spot disease can be prevented by 5% carbendazim 2. Fertilization technology of Myrica rubra: It is necessary to apply base fertilizer and topdressing well. Generally, 2-3kg/ of livestock manure can be applied to the base fertilizer, while potassium fertilizer is mainly used to fertilize the fruiting trees before sprouting.

1. Management techniques of Myrica rubra

1. Shaping and pruning

(1) After the first picking, it is necessary to prune off a proper amount of big branches, and prune off the high branches, cross branches, mopping branches and dense branches on the crown.

(2) During the second pruning, if the Myrica rubra trees with strong growth potential can be pruned early, otherwise, they should be pruned late. It should be noted that when pruning Myrica rubra, it is mainly necessary to cut off the old and weak branches, pests and diseases, too long and too dense, dead branches and other branches that do not grow well.

2. Protect the tree

(1) Because the big branches are not strong in resistance, they are easy to die after being exposed to the sun, so it is necessary to do a good job of protection and protection to prevent Myrica rubra from being exposed to direct sunlight.

(2) After it snows in winter, it is necessary to get the snow off the branches in time to avoid a lot of snow crushing the branches.

3. Prevention and control of pests and diseases

(1) Common pests and diseases of Myrica rubra mainly include brown spot disease, red coat disease, small moth, dead leaf moth, debt-repellent insect, etc. It is necessary to select appropriate chemicals according to the types of pests and diseases.

(2) Brown spot disease can generally be controlled by 5% carbendazim 6-8 times solution and 7% thiophanate methyl 8-1 times solution, while red coat disease can generally be controlled by spraying 2% Vindack 1-15 times solution.

(3) In general, the small moth and the dead leaf moth can be controlled by using 1 times of 4% Bupule EC and 2 times of 2% pyrethroid EC, while the debt-repellent insects can be controlled by spraying trichlorfon.

4, harvesting skills

(1) Because the ripening period of Myrica rubra fruit is different, it needs to be harvested in batches. It should be noted that bayberry fruit is easy to be scratched because it has no peel, so it needs to be picked, put and transported lightly.

(2) Generally, it can be harvested when 2% of the fruits of the whole tree are ripe, once a day or every other day, and it is appropriate to harvest in the early morning or evening, but not in rainy days or after rain in Chu Qing.

II. Fertilization techniques of Myrica rubra

1. Types of fertilizers

(1) Base fertilizer

① Generally, 2-3kg of cake fertilizer or 2-3kg of livestock manure can be applied to each Myrica rubra tree.

② It should be noted that the application amount of base fertilizer should generally account for about 6% of the total annual fertilization.

(2) Topdressing

① Generally, waxberry bearing trees need topdressing for 2-3 times throughout the year, and pre-bud fertilizer is usually applied in March-April, and the fertilizer applied is mainly potassium fertilizer.

(2) In May, strong fruit fertilizer can generally be applied. Potassium carbonate, calcium carbonate, livestock manure and other fertilizers are the main fertilizers, and boron fertilizer is applied in combination.

2. Fertilization method

(1) Trench fertilization method: A trench with a width of 3cm and a depth of 2-4cm is dug on both sides of the projected outer edge of the bayberry crown, and then fertilizer is applied.

(2) Radial furrow application: A circular furrow with suitable depth and width is dug at a place slightly far from the projected outer edge of bayberry crown, and then fertilizer is applied.
