General orchid culture method, pay attention to fertilization during flowering

Soil: it can be cultured in rotten leaf soil or mountain humus soil. Lighting: appropriate illumination when the sun is weak. Watering: the visible climate determines the amount of water, which can be watered every 2 days in spring and autumn. Fertilization: urea fertilizer and potassium dihydrogen phosphate fertilizer can be applied during the growth period. Temperature: the temperature should be kept at 16 ℃-24 ℃ during the growth period. Pest control: soapy powder and 500 times water can be used to kill insects.

First, choose soil

The main results are as follows: 1. General orchids like weakly acidic and humus-based soil, which can be cultured in humus soil or mountain humus soil.

2. In the south, local humus soil, vermiculite, perlite and rotten leaf soil can also be used to prepare loose and aerated culture soil. The formula is 50% rotten leaf soil plus 50% perlite, and the same amount of perlite can be added to the decaying leaf soil.

2. Proper lighting

1. The general orchid loves a cool environment and is afraid of direct sunshine. in spring, summer and autumn, it can be shaded before 9: 00 a.m. to 6: 00 p.m., open the curtains in the morning and after 6: 00 p.m., and properly bathe in scattered sunlight.

2. It can be moved to weak indoor light in winter, but direct sunlight should be avoided.

III. Principle of watering

1. The general's orchid likes to be moist and dry, and the watering times can be determined according to the growth situation and the local climate, so as to achieve the principle that it is not dry in autumn and not wet in winter.

2. it can be watered every 2 days in spring and autumn, and 1-2 times a day in the peak growth period in summer, while in winter, the general's orchid is dormant and can be watered once every 7 days to promote the growth and development of the general's orchid. When watering, it is necessary to avoid water droplets splashing on the leaves, which will lead to black spots on the leaves and affect their ornamental effect.

IV. Timely fertilization

1. The general orchid is first applied with base fertilizer during breeding, and then topdressing during the growing period, generally using liquid fertilizer and foliar fertilizer, and the concentration is lighter than that of other flowers.

2. The general orchid should change the culture soil once a year, and during the growth period, 15% dilute pancake fertilizer and water, or 0.1% urea fertilizer and 0.2% potassium dihydrogen phosphate fertilizer water can be properly applied every 18 days or so.

3. 0.2% potassium dihydrogen phosphate fertilizer water can be sprayed to the leaves for 2-3 times during flowering, so as to promote the development of general orchids.

4. General orchids belong to fleshy roots, which can not be fertilized with immature fertilizer, which is easy to cause rotten roots.

5. Suitable temperature

The main results are as follows: 1. The suitable temperature for orchid growth is 16-24 ℃, before Frosts Descent and when the temperature drops to 5 ℃ in the north.

2, put in indoor breeding, during the period should often open windows for ventilation, indoor temperature should be kept at about 10 ℃, in Grain Rain season should be moved to outdoor maintenance.

3. The indoor temperature will be relatively low in winter. Generally, the indoor temperature should be kept at 10-12 ℃ during the day and 5-10 ℃ at night. The temperature and humidity should not be too high. The temperature should not exceed 30 ℃ in summer.

VI. Pest control

1. The common diseases of senior general orchids are aphids and shell insects, which can be removed by hand or tweezers. Aphids are relatively small and can be killed by adding soap powder 500 times with water. Spray water once every 12 hours after spraying, which needs to be sprayed continuously for 5 days.

2. The general orchid loves dry but not dry soil, so too wet soil will lead to lack of oxygen in the roots, and when there is insufficient oxygen, it will produce a lot of alcohol to cause rotting roots. In order to avoid the occurrence of root rot, it is necessary to turn the soil frequently to make the soil have enough oxygen. It is appropriate to water a small amount of water for many times.
