Guidelines for the maintenance of Michelia mollissima with chlorine absorption effect

Michelia mollissima is an evergreen shrub with bright green leaves and banana flavor, which is admired by people because of its blooming, smiling and silent. There is also a reserved, implicit meaning of fancy language. Michelia mandshurica is native to the provinces and regions of southern China. It is wild in Dinghushan, Guangdong, and is born in the forest of mixed trees on the shady slope. Below Huinong net will talk to you about the environmental protection efficacy and maintenance guide of Michelia flowers.

1. Environmental protection effect

Michelia can absorb chlorine, flowers emit volatile aromatic oil, can play an inhibitory role in Mycobacterium tuberculosis, pneumococci.

2. Maintenance guidelines

(1) Light

Michelia prefers semi-shade to be afraid of strong light exposure, likes warm and humid climate, and is more hardy. Indoor potted plants can be placed in bright areas with more scattered light. Summer should be properly shaded to avoid direct glare.

(2) temperature

The room temperature in winter should be kept at 5-15 ℃. If the temperature is too low, it is easy to suffer frost damage. After suffering from cold, you can cover the basin with plastic bags and put it in the indoor sunny area for maintenance.

(3) watering

Keep the basin soil wet at ordinary times, but never get too wet. Because its roots are mostly fleshy, such as watering too much or basin waterlogging after rain will cause rotten roots, so we should pay attention to control humidity in rainy season.

(4) fertilization

Michelia likes fertilizer, apply fertilizer every 15 days or so in the growing season (April-September), and stop fertilizing after flowering and October. If you find that the leaf color is not bright and thick green, you can apply fertilizer and water for once.

(5) soil

Shaohua likes the deep and fertile slightly acidic soil. The pot soil was mixed with 6 parts of rotten leaf soil, 2 parts of garden soil and 2 parts of yellow sand to prepare culture soil.

(6) Reproduction

Michelia mollissima is commonly used in cutting and striping.

① cuttage

After flower fade, soft wood cuttings were carried out, 8-10cm long branches were cut, the upper leaves were left, and inserted into the basin soil to keep the basin soil moist and shaded, and rooting about 4 months after planting.

② striping

High-altitude pressing was carried out in the rainy season, and it took about 2 months to take root. Michelia is indoor medium-and small-sized potted flowers and trees, suitable for display in the living room and toilet.

The above is the Huinong net Xiaobian collation on the environmental efficacy of Michelia flowers and conservation guidelines, Michelia flowers can absorb chlorine, family breeding is also a good choice.

Is it difficult to grow rich trees and longevity flowers in summer? Some key techniques for the maintenance of these two plants in summer

Recently, when it is the hottest time in summer, many flower growers say that wealth trees and longevity flowers are not easy to raise. In fact, no matter what kind of flowers, there are certain ways of maintenance, as long as you master these ways, it is natural to grow flowers. Next, let's take a look at the guidelines for the conservation of summer rich trees and longevity flowers.

First, the rich tree

1. Root water control blade spraying water

The roots of the rich tree control water, in fact, water control means to control watering. Many people raise wealth trees because of their rotten roots, so remember that although it is in summer, do not water too much. Some people see that the surface of the flowerpot evaporates quickly in summer, and as soon as they see the soil on the surface of the flowerpot is dry, they quickly water it, but they do not realize that the water in the pot is still there. To judge whether the flowerpot is short of water, you can insert a chopstick in the pot and pull it out once every 2-3 days.

The leaf surface evaporates greatly in summer and is easy to dry. Sometimes even if there is no shortage of water in the basin, the leaves are drooping, so it is necessary to spray water to moisturize the leaves. Spraying water around the leaves of the rich tree with a sprinkler can not only cool down, but also make the leaves refresh quickly.

2. Strengthen ventilation

The wealth tree likes the ventilated environment most, the place near the balcony, windowsill, corridor and so on, not only ventilation but also some astigmatism, are very suitable for raising wealth trees. If it is not ventilated, the moisture in the basin can not evaporate in time, and it is easy to rot the roots.

3. Proper fertilization should be applied

It is said that the rich tree grows slowly, so you can't miss the summer growing season, so you can add fertilizer properly, mainly nitrogen fertilizer: soy rice water, bean cake water, or mixed with slow-release fertilizer, compound fertilizer and so on. Adding fat every half a month can make a big difference in one summer!

4. Treatment measures of rotten roots of yellow leaves.

If the leaves of the rich tree droop and turn yellow because of too much watering and lack of ventilation. At this time, quickly remove the yellow leaves, move the rich tree to a ventilated place, suspend watering, slow down for 3-5 days and then water normally when the situation improves.

If the situation does not improve in 3-5 days, still continue to yellow leaves, then quickly dig it out and have a look, the roots may have rotted. Cut off the rotten parts with a knife and soak in carbendazim or potassium permanganate solution for 20 minutes.

After disinfection, it is directly inserted into the water for hydroponics. The water here is preferably dried tap water (dechlorination). Hydroponics can add a little rooting powder or vitamin B and aspirin to accelerate rooting.

If you find it troublesome, you can also cut a twig for hydroponic culture. as long as it is a healthy one-year-old twig, the success rate of hydroponic culture is very high.

Second, longevity flowers

1. Longevity flowers can also blossom during dormancy.

When the temperature exceeds 35 degrees, longevity begins to enter the dormant period, but some people's longevity at home is opening. How is this going on? The factor that affects whether the longevity flower is dormant is the temperature. If you move the longevity flower into an air-conditioned room, or keep it on a shady balcony, if the temperature is about 23-30 degrees, it will not enter the dormancy period and will continue to grow normally. Beyond this temperature range, it will go in and sleep.

Light will also affect longevity flowers, if you shorten the light time, accept 4 hours of light during the day, the rest in the shade, so that a cold and hot temperature difference of 8-10 degrees, longevity mistakenly think that the flowering time has arrived, so blossom.

Of course, if your longevity flower has entered a dormant period, do not be so troubled, or learn how to spend the summer safely!

2. How to judge whether longevity is dormant or not

Most longevity will be dormant in July or August. If the growth rate of longevity slows down significantly, it means that the leaves are either yellowing or black rot if they do not grow or blossom.

3. How to spend the summer with dormant longevity

If your family's longevity is dormant, start watering less, move it to a cool and ventilated place, trim off all the yellow leaves, and reduce nutritional consumption. Don't do any fertilizing or changing pots first, wait until after September.

4. It is necessary to cut the longevity flowers.

If it is a dormant longevity flower, it is easy to grow, so you who raise longevity flowers must pay attention to this problem and find that longevity flowers should be pruned as soon as they grow, otherwise it will be too late to trim them in autumn. Longevity flower pruning can follow the principle of "getting rid of two and leaving four". For 6 pairs of leaf branches, cut off 2 pairs of leaves and leave 4 pairs of leaves.

The pruned branches of longevity flowers can be cut again, although it is now in summer and can be operated. The branches are planted in breathable sand, watered thoroughly, placed on a cool and ventilated northward windowsill, and sprayed with water to moisturize every day. It will take about 1-2 weeks to take root.

The temperature is high and the light is strong in summer, so no matter what kind of flowers you raise, you must do a good job in watering and other management. This is the end of the summer maintenance guide for wealth trees and longevity flowers, where the editor emphasizes that it is the heat of summer, so it is absolutely right to pay more attention to your own flowers and plants.

Cultivation methods and maintenance techniques of family potted rhododendron

How to plant potted rhododendron? Rhododendron is also known as the flower, which is one of the common potted varieties in many families. However, in the north, due to indoor dryness, how to improve the ornamental of rhododendron and prolong the duration of flowering is particularly important for family indoor cultivation.

1 ecological habits

Azaleas like to be born in a cool climate, avoid extreme heat and dryness, like fertile and loose soil. The optimum temperature for rhododendron growth is 12: 25 ℃. When the temperature exceeds 35 ℃, the plant grows slowly and the plant enters a semi-dormant state. Pay attention to sun protection in summer and cold and heat preservation in winter.

2 cultivation and maintenance techniques

2.1 selection of basin

Flower potted plants should choose suitable flowerpots according to the type, size and habits of flowers. Flowerpots have various types, rich forms and different sizes, and different flowerpots have different characteristics, such as mud pots, cement pots, tile pots, bamboo pots, ceramic pots, enamel pots, etc., as shown in Table 1. Planting rhododendron flowers should choose plain burning pots with good water permeability and air permeability. If you choose other flowerpots with poor water permeability and air permeability, the soil moisture can not be discharged for a long time after watering, which is easy to cause rotten roots and even death. Where planted in drainage, poor permeability of purple sand pots, porcelain pots, glaze pots and other flowerpots, should be used in the way of pots or holes in the bottom of the basin with more tiles to ensure good drainage and air permeability.

Table 1 types and characteristics of common flowerpots

2.2 soil

The choice of soil is very important for the growth of rhododendron, which usually grows vigorously in loose, well-drained and breathable slightly acidic soil. The soil in northern China is neutral or alkaline and needs to be improved when it is used.

Family flower cultivation can choose matured pine needle soil, rotten leaf soil under firewood pile, garden soil, chicken dung, river sand, cinder, sawdust, composting sawdust and other convenient substrates. Conditional can go to the flower market or online shop to purchase vermiculite, peat soil, perlite, orchid mud, rhododendron special matrix and other demanding substrates. Common rhododendron matrix formula, as shown in Table 2, mix evenly according to the corresponding proportion, properly add oil dregs, chicken manure, etc., can also add 1:2 beer and water mixture to improve soil acidity. Peat soil, pine needle soil and rotten leaf soil should be soaked at room temperature for more than 2 hours before use, and can be mixed with other substrates after soaking, so as to ensure the hygroscopicity of the matrix and avoid the phenomenon of "pseudo-wet".

Table 2 Common matrix formulations

2.3 change the basin

There are generally three situations in which rhododendrons are changed in pots: first, newly purchased rhododendrons are planted in nutrition bags or simple flowerpots, which are placed indoors to affect beauty and need to be pots; second, after 2-3 years of plant growth, the root system expands and fills the potted soil, and large pots need to be changed to expand the nutritional area; third, after 2-3 years, the nutrients in the pots are exhausted and the plants grow poorly, and the pots are changed to improve the soil and replenish nutrients. The time to change the basin is usually in autumn, and the basin is changed once every 2-3 years.

When putting on the basin, cover the drainage hole with tiles, put the coarse soil particles of 1 stroke 3 at the bottom of the basin as the drainage layer, and cultivate the soil slightly. Put the rhododendron into the basin, straighten it with one hand, control its depth, make the root system hang, put the rhizome at the place of 3~5cm under the mouth of the basin, fill the mixed culture soil into the basin with the other hand, fill to the place of 1~2cm under the mouth of the basin, and compact the basin soil. When changing the basin, pay attention to remove the old root, rotten root, damaged root, remove withered leaves and pruning properly.

2.4 watering

Family flower cultivation is often watered with tap water or well water, which should be placed 1-2 days in advance to increase the water temperature and disperse the chlorine in the tap water so as not to damage the plants. It can also be preserved by Rain Water to water the flowers. Watering time should be before 8:00 in the morning, 4: 00 in the afternoon and 6: 00 in the afternoon. Do not water at noon in hot summer. Adequate water supply should be provided during the growing and budding period, and the flowering period should not be watered too much, especially not spraying water to the buds so as not to wither the flowers early.

In general, the spring and autumn seasons 2-3 days watering, watering water to the bottom of the basin droplets, basin color darkened is appropriate; once a day in summer. You can also judge according to the degree of soil dryness, insert chopsticks into the basin soil, and if the soil is moist after pulling out, there is no need to water, and the soil below the surface of the basin soil should be watered immediately when the soil is dry; it can also be judged according to the color of the flowerpot, the basin soil is moist when the basin wall is dark, and the basin wall is white and lack of water; or the leaves are slightly drooping and should be watered immediately. 0.5%-1% vinegar can be applied every half a month to improve soil acidity.

2.5 fertilization

Rhododendron does not like big fertilizer, the principle of fertilization is thin fertilizer, family pot cuckoo usually apply fermented viscera, broad bean water, meat washing water, bean cake water, rice water, fish meal water, melon peel, vegetable leaves and so on. Appropriate addition of certain N, P, K fertilizers. During the growing period, alum fertilizer and water, or other rarefied fertilizer can be applied once in 2-3 weeks, and P and K fertilizer can be applied in the bud stage, and the flowers are large and colorful. 20g cake fertilizer was applied in spring and autumn to promote plant growth and bud formation.

The growth of rhododendron was stagnant from July to August, so it was not suitable to apply fertilizer. If the leaf is withered and yellow caused by too much fertilization, stop fertilization immediately, remove the dry fertilizer, irrigate and remove the fertilizer from the soil, and move it to the ventilated place for maintenance.

2.6 Lighting

Azaleas like light, but avoid direct sunlight, which is most suitable for semi-shady environment. Long-term in the indoor dark place is not conducive to flower bud differentiation, and easy to drop flowers and fruits, should be placed on the balcony or near the window culture, summer noon around the appropriate shade. In order to make the cuckoo grow in the same way, the cuckoo can be turned every week.

2.7 temperature and humidity

The optimum temperature of rhododendron is 12: 25 ℃. If the temperature is too high, it will go into dormancy. Spring and autumn can be moved to the outdoor breeding. The northern winter needs to spend the winter indoors, and the indoor temperature should not be lower than 5 ℃ to avoid freezing. When it is hot in summer, put it in a cool and ventilated place.

Azaleas like the moist air environment, when the air humidity is about 70%, the growth is good, when less than 50%, the leaves are easy to wilt, serious scorched edges, or even fall off. In order to keep the air moist, spray water on the leaf and surrounding air or ground in May and November (growing period). It is not suitable to spray water on leaves in spring, winter and flowering.

2.8 shaping and pruning

Pruning is to maintain a good shape, remove dense branches, residual branches, dead branches, cross branches, long branches, diseased branches, weak branches, improve ventilation and light transmission conditions, promote growth, and improve ornamental effect. Rhododendron is usually pruned after flowering, and the residual flowers are removed in time after flowering to avoid wasting plant nutrients, which is completed at the end of May. Pruning trees are umbrella-shaped, tower-shaped, round, semicircular, etc., according to everyone's preference.

The above are the key points of indoor pot cultivation and daily maintenance and management of rhododendron. I hope to provide help for the conservation and management of family potted rhododendron, and welcome senior flower friends to provide more valuable advice!
