Matters needing attention in breeding at the head of good luck

The humidity of the growth is very important, and the suitable relative humidity is 50%, 75%. Ventilation should be strengthened when it is higher than 80%, otherwise it is prone to disease or overgrowth. When it is less than 40%, it is easy to cause leaf tip withering, so it is necessary to spray water regularly to moisturize.

The maintenance of Hongyun should also be determined according to magenta. For varieties of happy light, such as colorful leaves, Hongyudang should shine more light and put it on the windowsill and balcony for maintenance.

The quality of watering is also very important to Hong Yun. It likes to grow in acidic soil and requires that the water quality be weakly acidic. It doesn't like salt, especially calcium and sodium.

Matters needing attention in daily breeding at the head of good luck

In daily maintenance, Hongyun must remember not to fertilize when blooming, otherwise it will lead to nutritious prosperity. And the flowers can be cut off in time after blooming, and then fertilized. Generally, cuttings are selected in the growing period of small plants.

Lucky luck blossoms only once, and cuttings or transplants should be carried out in time after flowering. Flowering usually occurs in the third year after the mature plant.

Its growth environment should be placed in a semi-shady and long-term ventilated place, always moist, because it is a parasitic plant, the soil will not take root very deep, if it is too much fertilizer is harmful, it will lead to root rot. Therefore, home cultivation is suitable for small pot planting.

Watering is usually watered before noon or in the morning and evening, and needs to be watered thoroughly. If photosynthesis cannot be carried out after watering at night, it is easier to survive germs. And if the temperature is too high, insect pests will occur, so it is recommended to control the temperature.

Key points for good luck in aquaculture

Red luck, that is, pineapple is an indoor ornamental flower in winter and spring, evergreen in four seasons, beautiful and colorful inflorescences, commonly cultivated varieties such as bright red, pink, golden yellow, rose and so on. The following is a detailed understanding of the key points of good luck in aquaculture and matters needing attention in breeding.

A brief introduction to the leading flower of good luck:

"Hongyudang" is a flower of the pineapple family, which blossoms at the top or middle of the plant. Good luck is a perennial evergreen herb. Leaves broadly band-shaped, curved, dark green. The spike is vertebrate, with dense bracts, bright red and yellow tip. Native to the Andes, China's Guangdong, Shanghai and other places to use greenhouse for growth and cultivation. Pineapple likes warm and humid environment. The suitable growth temperature is 21-28 ℃ in daytime and 18-21 ℃ at night. The highest temperature can not exceed 35 ℃. High temperature is disadvantageous to growth, but long-term exposure to 10 ℃ is easy to cause plant growth retardation, redness of leaves or bracts, discoloration of white and so on. If the temperature continues to drop, it will cause plant death.

Breeding methods and matters needing attention at the head of good luck

1. Ventilation

Ventilation temperature and humidity are closely related to the growth of good luck. Ventilation is not important when the weather is cool; when it is hot and humid, it is extremely muggy in the greenhouse or greenhouse. Good ventilation is very important for the growth of good luck. In the well-ventilated cultivation place, the plant leaves are wide and thick, the flower spike is large and long, and the flower color is bright and beautiful; in the poorly ventilated cultivation place, the plant is easy to grow too long, the leaf is narrow and weak, the flower ear is short, and the flower color is not glossy.

2. Moisture

In general, attention should be paid to the separation of the growing period and the dormant period in the cultivation area. Summer is the peak growing season for good luck, which requires a lot of water. About 3 mm of water is needed every day, and 10 mm of water is sprayed every 3 days. Watering should use room temperature water, pouring to the center of the plant (tubular center), so that the water flows through the leaves to the root and basin medium, so that it can be moist. In winter, Hongyun immediately enters the dormant period, it is necessary to control watering, spray water once a week at noon, each time 3 mm, to keep the basin soil micro-tide. If the pot soil is not dry or watered, it is easy to rot the roots if it is too wet. The bottom of the blade tube can be kept moist, should not give too much water, so as not to stink or even cause ornamental pineapple rot.

3. Temperature

Hongyundangtou is a CAM plant in photosynthesis, which adapts to a wide range of temperature, so it grows better in the environment with large temperature difference between day and night. The optimum growth temperature is 14 ℃ to 18 ℃, the daily temperature is 21 ℃ to 32 ℃, the temperature difference between day and night is more than 6 ℃, and the best temperature difference is 10 ℃. Hongyun is not cold-resistant, and the lowest growth temperature is more than 12 ℃. If it grows under the condition of less than 10 ℃ for a long time, Hongyun is vulnerable to cold damage. Therefore, the Beginning of Autumn should pay attention to the cold damage in the face of good luck, and the good luck of open-air planting should enter the house as soon as possible or increase protection facilities. If the plant is more mature and stimulated by low temperature, Hongyun is easy to blossom naturally in spring, so northern producers should pay attention to heating in winter.

4. Lighting

When the luminosity is strong, combined with high humidity and high ventilation, it can accelerate the growth of Hongyundang, make its plant shape strong, the leaf is wide, short and rigid, and the design color is more bright and beautiful. Lack of light is easy to cause overgrowth of plants, narrow and long leaves, weak and drooping leaves, poor color and low flowering rate. Hongyun likes strong light two months before flowering, and poor sunshine will affect the development of inflorescence and the brightness of spike color. Lucky luck needs at least 12 hours of sunshine a day, and if it can be increased to 16 hours, it will grow even faster. If the sunshine is less than 12 hours or longer than 16 hours, the plant will not grow normally and the flowering rate will be greatly affected.

5. Fertilizer management

The proper proportion of N, P, K and other elements is the key to the cultivation of high-quality luck. When the concentration of nitrogen fertilizer is too high compared with potassium fertilizer, the leaves will be narrow and long, and the leaves will be dark green; when the concentration of potassium fertilizer is too high, the leaves will be short and long; excessive phosphate fertilizer will cause the top burning of Hongyun leaves.

Boron, zinc and copper are harmful to Hongyun. Hongyun is a boron taboo crop, the application of boron fertilizer will cause the phenomenon of top burning. Zinc and copper will kill good luck. All good luck requires magnesium, which must contain 3% MgSO4 (magnesium sulfate) in the fertilizers applied. At the same time, add some calcium appropriately.

At the head of Hongyun, it is suitable to use liquid fertilizer and slow-acting fertilizer at the same time. The formula of liquid fertilizer should meet the following requirements: the pH value is from 5.5 to 6.0, and the ratio of various nutrient elements N P2O5 K2O MgO should be 10.51.50.5. Nitrogen fertilizer should be removed 2 months before flowering period, liquid fertilizer should be sprayed every 7 days, 30 ml per plant each time. Because the leaf cup of Hongyun has the function of absorbing water and fertilizer, liquid fertilizer can be applied directly to the leaf cup.

6. Pest control

Hongyun is a plant with few diseases and insect pests, and the main diseases are heart rot and root rot.

1. Both pathogenic heart rot and root rot are caused by fungi infection.

two。 The symptom of heart rot is that the tender leaf tissue of the heart of the injured plant becomes soft and rotten, showing brown, and the boundary between the heart and the healthy part is obvious, and the heart can be separated by gently touching with fingers. Root rot was caused by black browning and rot of the root tip of the affected plant, which did not grow lateral roots. the diseased plant was greatly affected by the absorption of water and nutrients, and the plant grew weaker and grew slowly.

3. The pathogenic environment is continuous overcast and rain in rainy season, high temperature, high humidity and poor ventilation. If the medium is poorly drained or sprayed too much, the pH value of the medium is higher than 7 or the water quality contains high calcium and sodium salts, and the seedlings accumulate for too long, it is easy to cause heart rot after transplantation. The seedlings are poorly ventilated after packaging, and it is easy to cause heart rot after planting.

4. Prevention and control methods to avoid high-temperature and humid environment, need to drain a good medium, to avoid high Ca, Na salt water quality.

Points for attention

1. In the environment of high temperature, humidity and poor ventilation, Hongyun is prone to diseases and insect pests, such as soot disease, shell insects and so on. If diseases are found, carbendazim can be sprayed in time, and pests can be sprayed with omethoate.

2. No matter what kind of liquid is sprayed, it must be carried out outdoors to prevent pollution of the indoor environment.

3. In addition, sterilization and insecticidal tablets can also be purchased in the flower market and buried in the basin soil to eradicate diseases and insect pests.

4. Red luck is fond of water, but watering needs to be carried out before noon, or in the morning and evening in summer, but it must be watered in the leaf cup, not only in the basin soil. And keep the leaves dry and clean at night, in order to humidify, you need to replenish water and humidify in the growing environment, such as sprinkling water on the ground or starting a humidifier.
