Anthurium is native to tropical rain forests in South America. Sex likes warm, moist and semi-negative environments, but it is not tolerant to yin, hi to the sun and avoid direct sunlight, not cold, happy
Fat and salt alkali.
Potted Anthuriums should use a well-drained matrix, and a mixture of peat, perlite, and sand should be used for large-scale production. The ratio is: 1 cubic meter peat: 4
To 5 kg of perlite: 0.15 cubic meters of sand. Its pH is kept between 5.5 and 6.5.
The optimum growth temperature is 20°C to 30°C, the maximum temperature should not exceed 35°C, the minimum temperature is 14°C, and there is a possibility of frost damage at any time below 10°C. Optimum
The relative humidity of the air is 70% to 80%, and it should not be less than 50%. Maintaining the high air humidity in the cultivation environment is the key to the success of Anthurium cultivation. therefore
Foliage should be sprayed more often throughout the year. The optimum light intensity is 10000 Lux and should not be higher than 30000 Lux.
Anthurium is not tolerant to light and should be cultivated in suitable shading conditions throughout the year, that is, greenhouses with protective facilities should be selected. Spring, summer and autumn should be properly covered
Overcast, especially in summer, requires 70% light shielding. Direct sunlight will cause the temperature of its leaves to be higher than the temperature. If the temperature of the leaves is too high, there will be burns, charred leaves, and the leaves will fade.
Tablets grow slower.
Anthurium can be propagated by ramets, sowing, tissue culture and other methods.
For ramets, select sunny days in spring, summer, and autumn. Gently remove the shoots from the pots by hand and double shoots (equal size).
First, planting
1. Pot size. Potted Anthurium differs from the seedlings to the big seedlings in different stages of growth. The seedling stage is generally completed at the nursery company.
The red seedlings we purchased were all above the middle seedlings (about 15 cm), so when we planted in the upper pot, the pots could be used once and for all 160150 mm.
Red straight edge plastic pots are planted.
2. Cultivation substrate cultivation. The matrix must have strong water retention and fertility, good permeability, no water accumulation, no toxic substances, and ability to fix plants.
Before planting, the substrate must be thoroughly disinfected to kill pests and keep their normal growth.
3. The planting of anthurium in the upper pot is a shade plant, and a shading net with a shading ability of 75% is required for planting to prevent excessive illumination. Better than double planting
When planting a single plant, it is very important to plant the growing point of the plant's heart to the level of the substrate when planting the upper pot. At the same time, it should try to avoid the plant contaminating the substrate.
When the basin is topped, it is filled with 4 to 5 cm of granular crushed stones and other materials in the lower part of the basin as a drainage layer, then the culture soil is added to 2 to 3 cm, and the plants are placed in the basin.
Central, to fully develop the root system, and finally fill the soil to the pot surface 2 to 3 cm can be, but should reveal the center of plant growth and the base of the leaflets. After planting
Bacterial agents must be sprayed in time to prevent the occurrence of Phytophthora and Pythium.
2. Water Management Anthurium is a species that is sensitive to salinity. Therefore, the pH of the substrate should be controlled between 5.2 and 6.2. The optimum PH value for Anthurium growth is
5.7. The EC value suitable for Anthurium growth is 1.2 ms/cm. Because of the high EC value, the flower becomes smaller and the flower stem becomes shorter, which reduces the ornamental value. spring
Suitable for planting Anthurium, but expensive; natural rain is the best source of water for Anthurium cultivation.
Potted Anthurium has different water requirements at different stages of growth and development. Seedling stage because of the weak root system, shallow distribution in the matrix, intolerant of drought,
Spray 2 to 3 times a day after planting. Always keep the substrate moist, promote the early emergence of more new roots, and pay attention to the dry humidity of the basin surface; medium and large seedling stage planting.
Plants grow quickly, require more water, water supply must be sufficient; flowering period should be appropriately reduced water, increase phosphorus, potash fertilizer to promote flowering.
The key to the success of large-scale cultivation of Anthurium is to maintain a relatively high air humidity, especially in the hot season, which can be increased through the spray system and atomization system.
The relative humidity of the air in the greenhouse (be careful not to spray the leaves in the evening, be sure to ensure that there is no water at night at the leaves of the apt) so as to avoid burning the leaves at high temperatures.
Occurrence of charred leaves, teratogenicity and fading. In the process of watering, we should control wet and dry alternately. Do not give watering if the water shortage occurs.
, This will affect its normal growth and development. In the hot season, it is usually watered for 2 to 3 days. At noon, the spray system should be used to spray water to the leaves to increase the room.
Relative humidity inside. Watering in the cold season should be performed from 9am to 4pm to avoid frostbite.
