Yunnan, Guizhou, Guangxi, Sichuan, Hunan, Jiangxi, Guangdong and Fujian can also be planted from October to late March of the following year.

2. Planting density. It is suitable to plant 33 ~ 42 plants per mu with row spacing of 4m × 4m or 4m × 5m. The ratio of male to female plants is 100 to 1, but it is not suitable for male plants if there are wild bayberry in the local area.

3. Apply basic fertilizer. The planting hole was 80 × 80 × 60cm, and each hole was treated with compost 50kg or barnyard manure 25-30kg or cake fertilizer 3-4kg, plus 1 kg superphosphate, which was covered with 15-20cm thick fertile topsoil.

4. Planting. When planting, place the seedlings in the center of the hole, stretch the roots, straighten the seedlings, then add fine soil and beat them with feet or hoes and other tools. Pour enough water to fix the root, cover the heart soil at the top to 20-30cm above the ground, and cover the grafting mouth under the soil. After the seedlings are planted, the soil should be loosened, watered and covered with tree plates in time in the high temperature season from July to August, so as to reduce water evaporation.

How to control bayberry diseases and insect pests? What kind of medicine should I take?

The main results are as follows: 1. The main disease of red bayberry is brown spot, also known as anthracnose, which is an important disease that harms the leaves of red bayberry. The disease seriously causes a large number of fallen leaves, causes insufficient nutrition of the tree, and finally leads to the decline of fruit quality. The pathogen overwintered as ascomycetes in diseased leaves, and the disease occurred in the last ten days of March to the first ten days of April of the following year. The disease was more serious in the land with shaded crown, lack of sunlight, barren soil, lack of potassium fertilizer and organic matter fertilizer.

Prevention and control methods:

(1) clear the garden. In autumn and winter, combined with pruning, focus on burning or burying diseased leaves, disease and insect branches.

(2) strengthening the management of cultivation: in the management of growing season, Heke should reasonably strengthen the management of soil, fertilizer and water, and at the same time improve the ventilation and light transmission conditions of trees combined with pruning. (3) spraying prevention and treatment: in the early stage of the disease, that is, after the end of flowering, 1500 grams of Baume per mu was sprayed with stone-sulfur mixture for prevention and control.

2. The main pest of red bayberry is whitefly, which is harmful to young shoots and leaves, which occurs more seriously in June and July.

Prevention and control methods:

(1) protect and make use of natural enemies such as ladybugs and wasps to control insects.

(2) when pruning in winter and spring, cut off dead branches and branches with high insect density, and concentrate on burning to reduce the source of insects.

(3) spraying control: in July, when insect pests are serious, better results can be achieved by spraying 4.5% cypermethrin EC per mu.
