Pontan is china's specialty flower, growing widely, with a long history, colorful and widely used. There is also a strong cultural climate. In history, there have been a lot of sluts who have fallen for the good of the police, and they have written their songs in such a way that they have seen all kinds of plumbs, poems, stories, stories, stories. Here's a key point in the field。

I. Morphological characteristics of the police
The police are pharmacists, pharmacists and shrubs that have been born for many years. Roots are flesh, thick and long, central woody, usually 0. 5 to 0. 8 metres in length, white and yellow (brown), with straight root, slope root and middle root. The length of the plant ranges from 0. 5 to 2 metres, the length of the branch is round, the length of which is straight, the surface of the new branch is smooth, the surface of the old branch is brown, it is often fractured and stripped, and the strains are of five types: vertical, evacuation, open, short, single. The leaves are two-and-a-three-resemble, interactive, deep green or yellow green on the leaves, and grey green below, smooth or hairy. The leaves may be of a large round, large long, small, small, medium type. The total lobe is 8-20 cm long and has a cavity on its surface, single-born, longer than the current-year branch, gender, colorful and morphological. The colours of the flowers are ten colours, white, red, yellow, pink, purple, purple, ink (black), snow, green, and resurgent。
Leave the bush. Tube up to 2 metres; small and thick branches. The leaves are usually two-and-three-repeated and occasionally close to the top, with three small leaves; small leaves of seven to eight centimetres wide, with a width of 5. 5 to 7 centimetres wide, 3 to the centre, non-fragmented or 2 to 3-sane, green on the surface, hairless, light green on the back, sometimes white powder, short, or near hairy, with small leaves of 1. 2 to 3 centimetres long along the veins of the leaves and small leaves of 1. 2 to 3 centimetres long; small leaves of small or rounded eggs of 4. 5 to 6. 5 centimetres long, 2. 5 to 4 centimetres wide, ranging from 2 to 3 shallow or non-fragmented, with near no handle; and leaves bearings of 5 to 11 centimetres long and with no hair on both sides. A single branch, 10 to 17 centimetres in diameter; a flower infarction, 4 to 6 centimetres in length; an ellipse, 5 centimetres in size; an ostrich, 5 green, wide ovary, varying in size; a petal, 5 or a heavy petal, rose colour, red purple, pink to white, usually very variable, fall-on, 5 to 8 centimetres in length, 4. 2 to 6 centimetres in width, with an irregular wavelength at the top; a male, 1 to 1. 7 centimetres in length, silk, pink。
Ii. Enforcement technology
1. Growing habits and the warmth of the climate and the harshness of the soil are best served by deep, loose and fertile sandy sandy soil. Heavy clay, saline is not suitable for title = planting techniques。
2. The ground and fertilizing, choosing fields of high ground, well-drained and well-ploughed. In combination with the whole area, pneumatic fattening: 3,000 kg of earth fattening per acre, 50 kg of pie fattening, 20 kg of urea and 50 kg of phosphate potassium calcium. Then we shall cast them, waiting for the seeding。
3. Seeding is carried out with seeds, seeding and planting. Most planting seasons are in autumn. The seedlings were first created by opening a shallow ditch on the right surface, and then evenly scattered the seeds of the police into the gutter, which was slightly suppressed, watered and covered a layer of crop straw. The seeds were planted with roots but not seeded. The following year, the spring break will be the beginning of the day.

4. Deplantation, which generally ranges from white to autumn. First, he digs a hole on the right face, then plants a year-old seedling into the cave. I'm going to water it to keep it alive. Line length 60 x 30 cm。
5. The main diseases of pest and pest control in the field are adhesion and folicosis. Prevention: 1. Treatment of seeds before seeding, with 10 g silicates or 0 per 50 kg seed. 2% quintozene blending. 2. Prevention of anti-fouling in the early stages of the disease with over 40% mgl. Underground pests are booby-trapped with phosphorus。
Iii. Management methodology for the police
The land on which the police are planted, because it is cold and hot, and it is dry and wet, and because it is afraid of the wind and cold, prefers soil estrangement, deep sandy border soil, and high and well drained. No replanting is allowed. In the 1 to 2 months preceding the planting of a large area of the pontoon, the land was fertilized to a depth of 0. 5 to 0. 8 metres in order to reach the depth of the leaf. The general requirement is a single-word slope, with a slight rise in the middle, and a rise around it to prevent soil erosion, flat inside, 2-3 metres wide and 10 metres long. A ditch is opened up and down, allowing one side of the water to flow and the quartet to see。
The difference in the time-use approach between the north and south of the country is greater. Most of the north plant before and after the fall, using vertically. In the south, most of the plants are built from summer to white fields, which are planted on a slope method, with the pharmacies growing 1,500 to 2,000 plants per acre, and around 1,000 per acre. Policing methods are representative of luoyang and monitoring ze。
In order to ensure the sound development of the police, emphasis must be placed on the application of fertilization. From the second year of cultivation, at least three fertilisations are applied each year, for the first time in spring to dawn, 15-25 days before the flower bloom. The year will be facilitated by supplementing the insufficiency of nutrients in the roots or branches themselves。
It is important that weeds be quenched frequently because of the warm ground of the police. Before flowering, two or three times before flowering, one or two times a month after flowering. After rainfall or watering, the soil is slightly dry and pine. The earth floor is 5 to 10 centimetres deep, the head is shallow, the crotch is deep (10 centimetres), thin, and it is not a place to live. In order to reduce water evaporation and maintain robust growth, the two, three or four-year-old policing can be dug shallowly to a depth of up to 15 centimetres to enhance drought resistance。
Finally, the knowledge of the techniques used to plant the porcelain flower, which is a traditional chinese flower, is complete. The king of the flowers and the fragrance of the sky. Always loved by the world。
