What should be paid attention to in daily maintenance of Phalaenopsis?

The butterfly orchid is large, white, with yellow-red labellum base and a pair of separate tendrils at the end. Sexual preference for warm, moist and semi-overcast environment. Potted Phalaenopsis should use porous and breathable plain roasting pots. The material should be loose, and the medium and small seedlings can be prepared with water moss and snake shavings. The adult plant should be mixed with charcoal particles and snake shavings. When planting, the planting material at the bottom of the basin should account for at least 1x2 of the basin capacity.

As Phalaenopsis has aerial roots and root tips with symbiotic fungi, it is appropriate to expose some of the roots in the basin or outside the basin, and do not bury them all deeply, otherwise they will hinder their breathing and growth. For Phalaenopsis planted in vegetable pots, it is appropriate to change pots and plant materials after flowering every spring, otherwise they are easy to accumulate dirt and moss, and plant materials are also easy to rot and breed diseases and insect pests.

Phalaenopsis does not need much light, which is about 1x3 of the illumination of orchids. Avoid strong light. When cultured outdoors, it should be shaded by 80% in summer, 60% in autumn and 40% in winter. Indoor culture, only 600 to 1000 lux intensity of light can grow well. The suitable temperature for growth is 20-30 degrees Celsius; if it is more than 35 degrees Celsius in summer or less than 10 degrees Celsius in winter, its growth and development will be inhibited; the overwintering room temperature should not be lower than 16 degrees Celsius.

Phalaenopsis is suitable to grow in high air humidity, and the optimum humidity during the day is 75%-80%. Therefore, during the growth period, it is appropriate to spray 2-3 times a day, and often drink to the ground, in order to increase air humidity. The new roots should be watered more in the prosperous period and less in the dormant period after anthesis. Water once a day in spring and autumn, one time in the morning and evening in summer, and one time every 3 days in winter.

Spring and summer are its vigorous growth period, thin liquid fertilizer based on nitrogen fertilizer can be applied once every 2 weeks, autumn and winter are the flower stem growing period, and sparse liquid fertilizer dominated by phosphorus and potassium fertilizer is applied every 10 to 14 days, such as 0.5% superphosphate aqueous solution. Stop fertilizing after budding, otherwise it is easy to drop buds early.

The domestic Phalaenopsis is propagated by the method of dividing the rhizome. The seedlings can be dug out from the roots of mature plants, with 2-3 roots, and then planted in a pot.

1 cultivation

1.1 spread a layer of sterilized wet pine needles on the bottom of the basin.

1.2 put the Phalaenopsis in a basin and let the roots spread out fully and evenly.

1.3 place the pine needle leaves at the root of the plant and press them gently.

1.4 after spraying water with a sprayer, put the plant in an indoor ventilated place and do not apply fertilizer. A month later, normal maintenance will be carried out.

2 watering

2.1 watering is done every day around 5pm in spring and autumn.

2.2 Summer is the peak period of plant growth, which is watered at 9: 00 a.m. and 5: 00 p.m. Every day.

2.3Water every 7 days in winter, preferably before 10:00 in the morning. If you encounter a cold wave, it is not suitable to water, and then resume watering after the cold wave. The water temperature of watering should be close to room temperature.

Novice tips: tap water for watering flowers should be stored for more than 72 hours.

3 light

Generally speaking, Phalaenopsis should be placed in an indoor place with plenty of light and soft light to avoid direct sunlight.

4 temperature

4.1the optimum growth temperature is 18 ℃ ~ 30 ℃.

4.2 in cold weather, the flowerpot should be moved indoors immediately so that it can survive the winter safely.

Novice tip: when moving the plant indoors in winter, do not put the plant too close to the radiator.

5 fertilization

5.1 Spring and summer is the growing period, dilute liquid fertilizer can be applied every 7 to 10 days, organic fertilizer or special nutrient solution for Phalaenopsis can be applied.

5.2 stop fertilizing when there are buds, otherwise the buds will wither early.

5.3 nitrogen and potash fertilizers can be applied after flowering.

5.4 Autumn and winter are the peak periods of flower and stem growth, and thin phosphate fertilizer can be applied once every 15 to 20 days.

6 Disease and pest control

The common pests of Phalaenopsis are thrips, shell insects, mites and so on, which can be controlled by spraying solutions such as quick killing and omethoate, while the larvae of some butterflies and moths can be sprayed with solutions such as Wanling, dichlorvos, insecticidal rings, etc.

7 pruning

The flowering stems should be cut off in time, leaving only the 3-4 nodes in the lower half.

Phalaenopsis daily maintenance and management methods in winter, Huinong net editor will briefly introduce this for flower friends, if you also want to know how other flowers manage and maintain in winter, please pay attention to our Huinong net!

Efficient cultivation techniques and Daily maintenance Management of Phalaenopsis in North China

Phalaenopsis is a kind of flower that many friends like. Today, the editor of Huinong Network has sorted out an article about the planting and management of Phalaenopsis in the north. Florists in the north, come and study quickly.

1 cultivation techniques of Phalaenopsis in North China

1.1 cultivation containers

There are differences in cultivation methods and cultivation containers. In general, large-scale cultivation of Phalaenopsis, cultivation containers can use tile pots or plastic pots. If it is in a flower shop or flower supermarket, the cultivation container can choose a decorative pot; if commercial flowers need to be properly maintained before they are on the market, you can choose 5~13cm 's transparent plastic nutrition bowl as the cultivation container.

1.2 cultivation substrate

In the process of cultivating Phalaenopsis, the substrate had better be the substrate with good aeration and drainage. In general, the frequently used substrates are peat, aquatic plants, sawdust, coconut shells, moss and so on, while the frequently used substrates in Dalian are aquatic plants. Planting Phalaenopsis in peat is also easier than water moss in overall management. For example, when planting Phalaenopsis with water moss, if the plug of water moss is too tight when changing the basin, it will affect the root growth, and if the plug is too loose, it will easily lead to acidification of water moss and rotten roots of Phalaenopsis, and the good permeability of peat can well avoid these problems, and the technical difficulty of potting will be reduced.

2 maintenance technology of Phalaenopsis in northern area

2.1 Seedling maintenance

In the process of maintaining the seedlings, we first need to carry out the pot operation of the seedlings, that is, after the seedlings are out of the bottle, they need to be transplanted to the basin of 5cm after 2 to 3 months, and then use the super aquatic plants that have been soaked 1 day before (the water content is about 30%), and wrap them in the root system of the seedlings to avoid exposing the roots. And the leaves can not be wrapped in aquatic plants, pay attention to loose and tight when wrapped, so as to avoid damage to leaves and roots. After completing the pot operation, it is necessary to pour half-thoroughly with 1500 times of methyl topiramate, or spray it with fungicides on the 2nd day.

2.2 maintenance of medium seedlings

There is also a certain standard when changing the basin of the middle seedling, if the leaf length reaches 12cm and the width is more than 3cm after 3-4 months, it can be transplanted into the 8cm basin, and if its root system is strong, it can also be transplanted. In the process of changing the basin, the seedlings that have reached the standard are mainly taken out of the 4cm basin and treated properly to remove the rotten or old roots. After the completion of the basin change operation, it needs to be maintained, sterilized 1 day after the basin change, and sterilized every 10 days thereafter. In general, fungicides can be used alternately with zinc Meng B Pu 800x solution + Yili 1000 fold solution or 99% tetracycline 3000 fold solution.

2.3 maintenance of large seedlings

When changing the pot of large seedlings, it can only be carried out after the middle seedlings have grown for 2-3 months. If the leaf tip distance is in 20cm and the root growth is very strong, you can change it to the basin of 11~13cm. When changing the basin, you first need to put a layer of Styrofoam particles in the transparent plastic bowl, and then put in the water plant, remove the rotten leaves and roots from the 8cm bowl, and wrap a layer of water grass. After the completion of the basin change, it needs to be properly maintained, and some seedlings of different sizes should be placed separately to facilitate maintenance, and sterilization should be carried out 1 day after the basin change, which is the same as the above operation.

2.4 Arrow maintenance

Usually, the flowering time is about 50 days. If the seedling starts to pull out the pedicel, stop the flowering operation at low temperature, and distinguish the plants that have already extracted the pedicel from those that have not. After the arrow, adjust the direction of the flower arrow in time, so that its leaves are in the east-west direction, and the direction of the pedicel is to the south of the growing point. During the period of arrows, proper maintenance is also needed, fertilizer and water are irrigated alternately, usually twice fertilizer and one water, fertilization can alternately use high phosphate fertilizer and average fertilizer, the dosage is 5000 times liquid.

2.5 flowering maintenance

The flower bud will germinate after the pedicel is pulled out for 30 days. At this time, the flowerpot can not be moved on a large scale, and the clamp needs to be mended in time. There are at most 3 clips for each flower arrow, and the highest clip is about 15cm under the first flower bud. During this period of time, it needs strong light, and 20000~35000Lux is the best light intensity, so it is necessary to choose the right light location. The temperature also needs to be properly controlled. During flowering, the best temperature during the day should be 22: 28 ℃, keeping in mind that it should not be lower than 20 ℃ or higher than 30 ℃; at night, the temperature should be controlled at 20: 25 ℃, the minimum should not be less than 18 ℃, and the maximum should not exceed 25 ℃. In the process of controlling humidity, the humidity should be kept at 60%-70% during flowering, the lowest should not be less than 50%, and the highest should not be more than 80%. Too high humidity can easily lead to plant diseases, which will eventually affect its commerciality; too low will greatly shorten its life span, and eventually there may be symptoms such as early withering of flowers. After flowering, the operation of fertilization can be reduced appropriately, and it is only necessary to apply fertilizer twice during the period from bud to flowering. In addition, it is necessary to supplement trace elements to promote the robust growth of the plant.

That's all about the planting and management technology of Phalaenopsis in the north. Farmers in the north and those who have this kind of flowers must learn the knowledge of this article.
