The growth conditions of azaleas are those of azaleas.

Do you know what is the culture method of azaleas? I believe that many flower friends are very concerned about the cultivation methods of azaleas and how to grow azaleas. In fact, azaleas are suitable for soil culture and potted plants. Today, I will work for everyone's welfare and introduce to you in detail the cultivation methods of azaleas. Next, let's take a look at the cultivation of azaleas.

I. Environmental conditions for the growth of rhododendron

It is best to have indoor and indoor environments for cultivating azaleas. The indoor environment is used in winter. In the Yangtze River basin, as long as there is a certain amount of light and ventilation, there is generally no need to heat up. The northern winter is extremely cold and dry, so it is suitable to be cultivated in greenhouse at medium temperature (about 15 ℃). Outdoor site, used in summer and autumn, it is better to use clay land, and avoid cement land. The site should be spacious, ventilated and shady, with shade sheds, covered with Reed curtains or protected by natural trees, with a light transmittance of about 30%. Avoid sunning at night.

Second, the cultivation of azaleas

1. Environmental conditions: it is best to have indoor and indoor environments for the cultivation of rhododendron. The indoor environment is used in winter. Outdoor site, used in summer and autumn, it is better to use clay land, and avoid cement land. The site should be spacious, ventilated and shady, with shade sheds, covered with Reed curtains or protected by natural trees, with a light transmittance of about 30%. Avoid sunning at night.

2. Pot soil requirements: azaleas like loose, strong permeability, good drainage, rich in humus acid soil, PH value is 5.0 Murray 6.0. If you use clay or alkaline soil, it is difficult to live. Summer cuckoos and rhododendrons, in particular, must be mountain soil. The mountain soil needs to be reformed. at present, three kinds of culture soil are usually used.

3. Flowerpot selection: the flowerpots for cultivating azaleas are generally mud pots and purple sand pots. The mud basin is well ventilated and permeable, and it is used in the cultivation of production units. The molded azaleas, especially the modeled azaleas, are furnished for indoor and outdoor furnishings, generally planted in a beautiful and quaint purple sand basin with delicate texture, rich color and beautiful shape, which can double the ornamental value.

4. Improve water quality: it is best to use Rain Water to water azaleas, followed by river and pond water. If tap water is used, it is advisable to store the water for 2 days and let the chlorine volatilize and then use. Add 0.2% ferrous sulfate when you use it, and water it every 10 days during the growing season. Use it frequently to ensure that the soil is acidic.

5. Fertilizer and water management: rhododendron likes yin and dampness and should not be too dry. More moisture is needed during flowering. Rhododendron has entered a dormant period in winter and does not require much water. It is generally watered every 4 times every 5 days, which should be carried out around noon on sunny and warm days.

6. Outdoor shading: there should be more sunlight before leaving the room and before civilization; during flowering, shading should be carried out for a short time at noon, and the light transmittance is 60%.

7. Shaping and pruning: in order to accelerate the blooming of plants, cuckoos often promote new branches by picking their hearts, and those who cluster around flowers and affect their shape can sparse buds earlier, which not only makes the flowers big and fresh in the current year, but also helps the plants to grow and bloom in the coming year. Rhododendron has strong germinating power, and its branches seriously affect plant growth and development, reducing its ornamental and commercial properties, so it needs to be adjusted by pruning. Pruning is generally carried out after blooming in spring and autumn, cutting off withered branches, oblique branches, long branches, disease and insect branches and some cross branches to avoid nutrient consumption and make the whole plant blossom and full.

8. Disease prevention and insect control: military insects (also known as crown net bugs) are sprayed with 1500 times of dimethoate during the damage period, once every 7 days for 3 times in a row. The control methods of terminal bud leaf rollers are mainly killed by artificial capture, and the larvae or pupae can also be sprayed with 2000 times of dimethoate EC or 1500 times of dichlorvos.

9. Florescence control: rhododendron flower bud differentiation in autumn, through cold storage and heating treatment, the florescence can be artificially controlled. To make the cuckoo blossom ahead of time, it can be cultured in a greenhouse, the temperature is controlled at 20 ℃, and water is often sprayed on the branches and leaves to maintain a relative humidity of more than 80%, so that it can blossom in a month and a half. In order to delay the flowering of rhododendron, the cuckoo that formed buds can be kept at low temperature all the time, and the temperature should be kept at 2 ℃. The cuckoo should be watered when the pot is dry, and the cuckoo can blossom outside in summer and autumn after 2 weeks.

The above is the relevant introduction of this article, I believe you have a simple understanding of this after reading it, if necessary, you can continue to pay attention to the No. 1 home network for more information.
