Hey, turn on your phone early in the morning, the director saw a message: Chinese scientists in the field expedition to rediscover the dry rhododendron has long been declared extinct in the wild.
Since only one plant has been found in the wild, "rescue protection" is urgently needed. Experts suggest that it is necessary to further adopt a "carpet" systematic investigation to thoroughly find out the resource background of this kind, and at the same time carry out "rescue protection" and systematic research work...
Azaleas are quite simple to plant and can bloom for many years under the right care.
If every household plants a little rhododendron potted plants, not only will the balcony, roof, and yard be full of life, but also where is the fear that the cuckoo will become extinct?
Follow the planting secrets of the station director and learn how to plant and maintain azaleas!
【Growing conditions】
1. Be sure to remember that azaleas are afraid of cold and cold.
Taiyou who live in the Yangtze River Basin generally do not have to be heated as long as there are certain lighting and ventilation conditions on the balcony at home.
Winters in the north are extremely cold and dry, and it is advisable to cultivate them in a moderate temperature (about 15 °C) greenhouse.
2. Grow rhododendrons outdoors, with mud as a good, avoid direct planting on cement.
3. The planting site should be spacious, ventilated and shaded, and a shade shed should be built on it, covered with reed curtains or borrowed from natural shades, and the light transmittance rate of about 30% should be appropriate, and it is advisable to avoid the sun at sunset.
【Soil requirements】
Growing rhododendron for many years, the director is familiar with rhododendron's loose, permeable, well-drained, humus-rich acidic soil.
Oh, if Taiyou used clay or alkaline soil to plant rhododendrons, it would be difficult to survive. In particular, the summer crane and the ocean crane must be mountainous.
We can potted rhododendrons on the balcony, you can improve the soil yourself, 3 kinds of formulas of cultivation soil, Taiwan friends can choose their own.
Recipe 1
7 parts of mountain soil, 1 part of dry moss grass chips, 2 parts of dry saprophytic soil, and 1 part of dry fertilizer are mixed and prepared.
Recipe 2
3 parts of mountain bark soil (topsoil), 3 parts of horse manure, 3 parts of deciduous weeds, and 1 part of human feces and urine are stacked in layers, and after 1-2 years, they are sieved and prepared.
Recipe 3
Mix 3 parts of mountain soil, 3 parts of saprophyll soil, 4 parts of garden soil, and 2 parts of sand soil, and add 50 grams of sesame sauce residue and bone meal to each pot.
【Pot requirements】
◆ Choose the material of the pot
The pots of cultivated rhododendrons can generally be selected according to the use, two kinds of mud pots and purple sand pots.
Mud pot - good ventilation and water permeability, is conducive to root growth, production unit cultivation are used in this pot.
Purple sand pot - permeability is not as good as mud pot, in the planting, should be surrounded by pot wall pads with broken tiles (old tiles) so as to facilitate drainage.
Molded rhododendrons, especially the shaped azaleas, for indoor and outdoor furnishings, are generally planted in beautiful and elegant purple sand pots, the purple sand pots are delicate in texture, rich in color, beautiful in shape, and can double the ornamental value.
◆ Choose the size of the pot
Depending on the age of the plant, generally 4-6-year-old plants use 5-inch pots, 7-10-year-old plants use 6-inch pots, and 11-15-year-old reproductive plants use 8-inch pots.
【Water selection】
Water the rhododendrons, praise the best use of rainwater, followed by river water, pond water. If tap water is used, the water should be stored for 1 to 2 days, so that the chlorine vapor volatilizes and then uses.
Oh, the above paragraph, you must turn your back like a stream, so home gardening is watered like this.
When used, add 0.2% ferrous sulfate, water every 7-10 days during the growing season, and use frequently to ensure that the soil is acidic.
【Watering Management】
In March, rhododendrons sprout and water demand increases.
Summer cranes grow and develop slightly later, and the amount of watering should be less than that of spring cranes. Generally every 2 days in the morning, water in an appropriate amount.
From April to June, the rhododendrons bloom one after another, and the branches and leaves begin to twitch, requiring a large amount of water, and should generally be watered once every morning or evening.
During the high temperature and dry season from July to early September, water once in the morning and once in the evening, the amount of water should not be too much, and spray water on the foliage and ground at noon to maintain a humid environment.
From mid-September to November, the weather gradually turns cooler, which is the adaptation period for the growth of rhododendrons, in order to prevent the extraction of autumn shoots and enhance the wintering resistance, the amount of watering should be reduced in an appropriate amount. Generally, water once every other morning to keep it moist.
Winter rhododendrons have entered the dormant period, the amount of water required is not much, generally every 4-5 days watering, should be carried out around noon on sunny and warm days.
【Fertilization Management】
Rhododendron flowers are more fertile, generally using decomposed cake fertilizer, fish meal, broad beans or purple cloud ying and other decayed watering, avoid using human feces and urine.
After leaving the room
Before the buds spit out flowers, apply a thin fertilizer every 10 days, the concentration is 15%, a total of 2-3 times, to promote the old leaves to turn green, germination of new roots.
After the flowers are removed, in order to promote the growth of branches and leaves, fertilize 5-6 times from mid-May to early July. If it rains continuously, dry fertilizer can be applied.
Before entering the room
Before the growth of rhododendrons is about to stop, fertilization should be applied 1-2 times.
【Shade management】
Before leaving the house to before the enlightenment, more sunlight should be seen; during the flowering period, a short period of shade should be carried out at noon, and the light transmittance rate is 60%.
During the rainy season from June to early July, it is the rhododendron leafing and branching period, and as much sunshine as possible should be seen. However, in the event of strong sunshine, shade should be taken from 9 a.m. to 4 p.m. to prevent burning of new leaves.
From mid-July to early September, shade is provided daily from 8 a.m. to 5 p.m. to prevent the sun from shining.
The autumn growth period after September can shorten the shade time, generally from 10 a.m. to 4 p.m., and more sunshine should be seen after October.
After plastic surgery, long branches, diseased branches, deformed branches, and damaged branches are cut off.
【Shaping and trimming】
Rhododendrons grow slowly, generally allowing them to grow naturally, only after flowering, plastic surgery, cut off long branches, diseased branches, deformed branches, damaged branches.
【Disease prevention and treatment】
The military insect (aka crowned reticulum bug) sprays 40% Leguo 1500 times liquid during the hazard period, once every 7 days for 3 consecutive times.
The top bud leaf curling insect control method mainly relies on manual capture and killing, and the larvae or pupae can also be sprayed with 40% Lego emulsion 2000 times liquid or dichlorvos 1500 times liquid.
