Sowing method of Peacock Grass

Peacock grass-can be sown all year round. However, due to the limitation of flower conditions, the flower consumption of "May-" and National Day is the largest. Because the seeding temperature of peacock grass is higher than 15 degrees Celsius (or there are heating and insulation conditions), the seeding period of the middle and lower reaches of the Yangtze River is generally from August to November. Sowing can be carried out all year round in the south where the climate is warm, but spring sowing is popular in the north. If it is in early spring seedlings, attention should be paid to ensure that-a fixed growth temperature, try to avoid growth stagnation. Sowing should adopt loose medium, bed sowing, box sowing seedling, conditional can adopt plug seedling. After disinfection treatment, slightly covered after sowing, the germination temperature of peacock grass is 22~24 ℃.

(1) Stage II-stage: 2~5 days after sowing, white (embryo exposure). The seeds germinate without light and are usually covered with a thin layer of medium after sowing, so that they can be shaded and kept moist at the early stage of seedling. Keep the medium moist, but prevent excessive humidity, and keep the temperature at 21~24 degrees Celsius.

(2) Stage II: 7 days from radicle emergence to cotyledon development. Once the radicles appear, lower the temperature and water the medium after it has dried slightly for better germination and root growth. And a small amount of fertilizer is applied to the light.

(3) The third stage: rapid growth period of seedlings, seedling growth of peacock grass to prevent excessive humidity, so between two watering to let the medium dry, of course, can not make the medium too dry to cause seedlings to wither, medium and environmental temperature can be appropriately reduced to 18 degrees Celsius. Alternate fertilization every 5 to 10 days. Ammonium nitrogen fertilizer should be avoided if the medium temperature is below 18 ° C. At the end of this stage, the root system can grow to 3 - 5 cm, the seedling height is 3 - 4 cm, and 2 - 3 pairs of true leaves.

(4) The fourth stage: seedling stage, the root system has been formed well at this stage. There are 3 pairs of true leaves, and the temperature can be lowered to 15~17 degrees Celsius, but it is best not to fall below 15 degrees Celsius. But avoid ammonium nitrogen fertilizer. As in the second stage, the medium should be dried thoroughly between the second watering, and ventilation should be strengthened to prevent excessive growth. If seedling failure or problems exist, eliminate possible seed quality problems, the main reasons are: -the ph value of the medium is too low, the main symptoms are necrotic spots on the old leaves, burnt edges, growth point necrosis. If the pH value is lower than 6.0, it will also cause excessive amounts of certain trace elements such as magnesium, iron, sodium and zinc. The main solution is: keep the pH value of the medium between 6.0~6.7, can be adjusted by adding 0.4526 kg lime in 38 kg water; third, early spring low temperature seedling, such as high temperature, easy to occur disease. It begins with water stains at the base of the stem, then necroses and lodging. Therefore, attention should be paid to raising the temperature as much as possible in early spring seedlings and controlling humidity to prevent diseases. Fourth, pay attention to seedling nutrition, if seedling lack of fertilizer, water shortage, thin plants, will form small old seedlings.

1. How to grow grass seedling stage

Peacock grass itself is very easy to plant, but when seedlings may have moth larvae nibbling leaves, found timely treatment spray on the line.

2. watering

Water peacock grass to pay attention not to appear ponding, watering thoroughly every time, keep the soil moist dry can, do not be too wet, otherwise affect the growth of peacock grass.

3. substrate treatment

Generally, it is best to choose loose and fertile sandy soil as the substrate, and after the substrate is selected, it should be disinfected to remove pests and diseases.

4. temperature

Although peacock grass adaptability, can survive indoors, but sufficient sunlight can make them bloom better, the temperature is best at 18 degrees Celsius, winter 6 degrees Celsius below to pay attention to insulation, in case plants freeze to death.

As long as you trim the branches and leaves and fertilize them properly, you can raise beautiful peacock grass. Peacock grass also has the effect of purifying the air. It is a natural air purifier. It can purify the air at home. What are you waiting for? Let's plant together.

The cultivation method of peacock grass

Peacock grass, also known as small marigold, red and yellow grass, western chrysanthemum, smelly chrysanthemum, satin flower, etc., is an annual herb of Compositae marigold, native to Mexico, often cultivated in gardens all over China, in central and northwest Yunnan, central and southwest Sichuan and western Guizhou have been naturalized, let's take a look at the planting methods of peacock grass together!

The growth habit of peacock grass

Peacock grass is born in the hillside grassland, forest, or garden cultivation at an altitude of 750~1600 meters. It likes sunshine, but it can also bloom when planted in the shade. The soil requirements are not strict, both resistant to transplanting, and rapid growth, cultivation and management is very easy. The seeds scattered on the ground can grow by themselves in suitable temperature and humidity conditions, and are a kind of flowers with strong adaptability.

Breeding method of peacock grass

1. Sowing and propagation: The seeding and propagation of peacock grass are carried out from November to March, and the flowering of winter and spring sowing can be carried out from March to May. The seeding can be directly broadcast in the courtyard or potted. The potted seedlings can be dug up and planted in the pot about one month after sowing.

2, cuttage propagation: peacock grass cuttage propagation in June to August cut about 10 cm long shoots directly inserted in the courtyard, shade cover, rapid growth, directly inserted in the flowerpot can also be. Summer and autumn cuttings bloom from August to December, and cuttings can survive whether they are inserted into the ground or in cuttings (pots).

The cultivation method of peacock grass

1. Transplanting the upper pot: The seedlings of peacock grass should be transplanted into the upper pot when they grow to 2~3 pairs of true leaves. Most of them are accustomed to using 12 cm diameter nutrition bowls in Zhejiang Province. The upper pot is in place once, and no longer changes the pot once. If it is broadcast seedlings with open seedling tray, it should be sparsely sown, and in 2~3 pairs of true leaves, directly transfer seedlings to the pot.

2. Light regulation: Peacock grass is a positive plant, which requires sufficient sunshine for growth and flowering, and sufficient light is also conducive to preventing excessive growth of plants. However, in July to September in our province, it is necessary to avoid direct sunlight and shade and cool down around noon.

3, temperature control: after the pot temperature can be reduced from 22 ° C to 18 ° C, after a few weeks can be reduced to 15 ° C, before and after flowering can be as low as 12~14 ° C, such a temperature for the formation of good plant shape is the most ideal, but in actual production may be difficult to achieve this condition. Therefore, generally speaking, as long as it is above 5 ° C, it will not be frozen, and it can grow well between 10 and 30 ° C.

4, water management: the key to water management is to use a good drainage medium, keep the medium moist, although important, but proper drying before each watering is necessary, of course, can not make the medium too dry and lead to plant wilt.

5, fertilization method: peacock grass for completely cultivated with artificial media, fertilization should be 20-10-20 and 14-0-14 fertilizer, with a concentration of 200~250ppm 7~10 days alternately applied once. In winter, when the temperature is low, reduce the amount of fertilizer used by 20-10-20. If the medium is ordinary soil, compound fertilizer can be mixed as base fertilizer before the medium is potted. If the fertility is insufficient, then apply water-soluble fertilizer.

6. Disease and pest control: Common diseases of peacock grass include brown spot disease, powdery mildew, etc., which belong to fungal diseases. It should be cultivated well, and attention should be paid to irrigation, removal of diseased plants and diseased leaves, burning of residual branches, and timely spraying of fungicides such as rust powder.
