How to raise four Seasons Cassia Culture methods and matters needing attention

Sijigui originated in the Mediterranean Sea. At present, there are many introduced plants in southern China, so Sijigui is suitable for growing in warm and humid places. Sijigui ornamental value is very high, and as wood also has a high use value.

So, how should the four seasons be raised? What kind of farming methods and what needs attention?

How to raise four seasons

1. It is suitable for growing in warm, humid and sunny places. The soil planted should be fertile, loose, slightly acidic and well drained. Sijigui is drought and cold tolerant, and its growth temperature is 20-30℃. If there is no extremely cold wave in winter, it can generally overwinter in the open field.

2, four seasons laurel xi warm, generally in 18℃ to 25℃ when the growth is good, flowering and fragrance. If it is below 15℃, it is in a semi-dormant state and flowers less. 3℃ to 5℃ can winter, but can not bloom.

Four season laurel cultivation methods and precautions

First, we must choose the basin soil

Osmanthus flowers like slightly acidic, well-drained, fertile sandy loam. Osmanthus fragrans grows slowly in strong acid soil, with yellow leaves and withered leaves and few branches; in soil with pH value of 3 - 4, grafted two-year seedlings have 2 - 3 branches in the current year, and the branch length is only 6 cm, which is 2 times less than that in soil with pH value of 6, and 1 - 2 times shorter.

In alkaline soil, leaf withered ginger appears in two or three months and gradually dies.

Second, the flower is fat

1. Osmanthus likes pig manure. It can be mixed in the basin soil, or applied to the bottom of the basin after decomposition and drying.

2. The amount of fertilizer should be 1/4 of the pot height. The fertilizer should be covered with a layer of soil about 1 inch to 2 inches thick, and then planted with four seasons laurel. No fertilizer should be applied within one year.

3. In places where there is no pig manure in the city, the hoofs of donkeys, horses and mules can be retting into water, which can be poured once in spring when it germinates, and once every 7 to 10 days until August. Can also be used sauce residue, fried soybeans, raw peanuts fried, ground into a surface, digging ring root buried in the basin soil.

Third, watering should be appropriate

1. Osmanthus watering should master two less and one more.

2. Less watering is needed for plants that change pots before new shoots occur, less watering is needed for rainy days, and more watering is needed for dry and early days in summer and autumn.

3, after changing the basin to irrigate the water, often maintain about 50% water content, the summer (7 - 9) month soil moisture content should be about 60%.

4, but also to maintain air humidity. Put osmanthus flowers in the shade, spray water to the leaves once a day in the morning and evening. Or put a fish tank or small basin containing water next to it, and put osmanthus flowers in the open air to withstand night dew and humidify to keep the leaves fresh.

IV. Control of florescence

1. The flower bud formation and differentiation of Sijigui need to go through the process of high temperature-low temperature-high temperature.

2. The flower buds began to differentiate at about 30℃, 25 days to 31 days, and the flower buds began to germinate after 3 days to 5 days of dormancy at 15℃.

3. After flower bud sprouting, it blooms quickly at a high temperature above 25 C.

V. Modeling

1. Osmanthus fragrans mainly focuses on leaf observation, flower observation and flower observation. Flowers small but fragrant, mainly leaves and type beauty.

2, modeling to show prosperity, dignity, elegance and innocence of the spirit.

3, you can choose privet as rootstock, first move the big leaf privet to the flowerpot, from the summer solstice to the autumn equinox this time, all available grafting method, that is, the osmanthus branches, close to the privet branches, remove the privet branches.

4. After survival, cut osmanthus fragrans from the mother.L to form a new osmanthus fragrans, and the survival rate can reach 100%.

Grafting method of rootstock of osmanthus fragrans

1. There are mainly privet, white wax, clove, tassels, etc.

2. The disadvantage of Ligustrum lucidum as rootstock is that the root system is too developed, it is not suitable for potted plants, and it blooms late.

3. The disadvantage of white wax as rootstock is short life span, easy deciduous in winter and less flowering.

4. Cloves as rootstock are thick at the top and thin at the bottom, and the tree is top-heavy and light.

5, tassel as rootstock affinity is good, drought and cold resistance, adaptability is strong, life is long, the age can be as long as more than 100 years. Therefore, the most suitable rootstock for grafting propagation of potted osmanthus fragrans is tassel.

Common Diseases of Cinnamomum cassia

1, four seasons cinnamon blight disease: the disease pathogen mostly from the leaf edge, leaf tip invasion, occurred in the leaf edge and leaf tip.

2. Anthracnose of Osmanthus fragrans: This disease infects Osmanthus fragrans leaves.

Sijigui Sijigui has certain resistance to harmful gases such as hydrogen fluoride and sulfur dioxide, which can reduce the pollution degree to the environment. Planting in public places or home courtyards can play a good role in greening, beautification, fragrance and purification. Therefore, flowers and gardens are planted in many places.
