Green emperor is one of the most popular foliage plants. It has the function of environmental protection. It can absorb dust and a lot of carbon dioxide in the air, release oxygen and make the indoor air fresh. So how does the green emperor breed? Let's go and have a look~
Green emperor's breeding method green emperor's breeding method (basic knowledge): the best breeding time: Green emperor grows vigorously in spring, summer and autumn;
The best growing soil: Green emperor should be planted in acid soil;
Growth humidity requirements: Green emperor suitable humidity at 50-70%, if the humidity is less than 50% yellow leaf dry edge, air spray can be used to increase air humidity;
The best growth temperature: the green emperor likes warm environment and is afraid of severe cold. The suitable temperature is between 20-30 ℃. The winter temperature should not be lower than 10 ℃. Otherwise, the green emperor is vulnerable to freezing injury and death, and begins to grow at about 13 ℃;
The best growth light: the green emperor likes the scattered light of Yin Liang, avoid direct sunlight.
The cultivation method of green Emperor
Green emperor should use mature farmyard manure as base fertilizer, and topdressing should be carried out according to the situation during the growth. From April to September, the leaves grow vigorously, and liquid fertilizer is applied twice a month to ensure that the leaves are large and glossy.
Watering points:
The green emperor grows vigorously in spring, summer and autumn, and needs sufficient water and fertilizer. Watering should be done to pour thoroughly, and according to the season, temperature flexible control, in principle, keep the basin soil moist state. Also pay attention to the foliar spray, in order to maintain high air humidity, is conducive to the leaves of the dark green two.
Pruning tips:
The green emperor changed the pots once a year in spring, and removed the branches and old leaves to keep the stem beautiful.
Basin soil replacement:
The green emperor changes the pots every spring.
Breeding points:
The propagation of green emperor mainly adopts tissue culture, cutting and ramet method, also can be hydroponics.
Cutting propagation: the cutting should be under the node, the cutting temperature should be 25 ~ 30 ℃, and the humidity should be kept, so it is easy to survive. The method is simple and convenient.
For water transplanting, the upper branches of stems and vines should be cut off, and the aerial roots should be inserted into water together, and new roots will sprout in about 10-15 days. The family hydroponics green emperor, should use the small plant, often spray water to the plant surface, keep the leaf fresh. The stem of green emperor is thick and strong, and the ornamental effect is better if it is cultivated upright. And give appropriate scattered light source.
When the plant is divided, the plant should be cut again. When the young plant germinates from the stem node, it can be cut off and potted directly. Cutting, cut the stem into 2 to 3 segments, insert directly into the coarse sand, keep moist, and take root about 20 days after cutting. You can also cut off the top stem node into the water bottle, change the water every two or three days, 2 to 3 weeks after the new root, and then implanted in the pot. During the vigorous growth period from April to September, liquid fertilizer should be applied twice a month or sprayed on the leaf surface to ensure that the leaves are large and glossy, and provide sufficient water to keep the basin soil moist.
In winter, the growth rate is slow, so fertilization should be stopped and irrigation water should be reduced. Direct sunlight in summer and autumn will make the leaves appear brown spots and yellow leaves, so it is necessary to cover 50% of the light outdoors in summer and autumn, and it is necessary to keep sufficient sunlight indoors in winter. Green emperor is a vine plant. If it is a large potted plant, it needs to be pinched many times to lower the plant shape, increase the plant's own support ability or set up pillars for binding modeling..
Pest control:
Root rot
Long term over wetting of substrate, watering after drying of substrate, high EC Value of substrate and damage of root system all lead to the occurrence of root rot.
Anthrax
Excessive humidity and damaged leaves are easy to cause anthracnose. The diseased leaves can be cut off and then treated with chlorothalonil and thiophanate methyl 800 times alternately.
Harm of Spodoptera litura
It can be controlled with 1000 times of fenpropathrin.
The cultivation method of green Emperor: 1. The cultivation soil should be mixed with rotten leaf soil or peat soil and a small amount of river sand and perlite, and bone meal or cake fertilizer should be used as base fertilizer.
2. Organic liquid fertilizer should be applied once or twice a month during the growing period.
3. During the growing period, the basin soil should be kept moist. In summer, water should be sprayed on the surface of leaves and the ground around the basin to increase humidity and reduce temperature; In winter, water and fertilizer should be controlled to keep the basin soil slightly wet.
4. Should be placed in the room where the light is bright maintenance, but can not be placed in the dark for a long time, easy to cause excessive branches and leaves.
