Whelan farming methods? Whelan indoor farming method A brief introduction to the Whelan indoor farmi

This is melanoma, and the main features are:

February and March are the peak periods for infection, and it is easy to get infected due to continuous rain and little sunshine. Mainly infect the leaves, the diseased leaves appear brown spots, rapidly expand round, semicircular black spots, there are often water-stained light yellow halos around, with a diameter of 1 cm 17 cm, the later disease part ** gradually fades, the leaf tissue between the lesions loses green and turns yellow, and multiple lesions are connected into large plaques.

Prevention and control methods: pay attention to the selection of disease-free seedlings. Remove diseased leaves and fallen leaves, cut off the lesions in the upper and middle parts of the leaves in time, and burn them intensively.

Before the onset of the disease, 1% Bordeaux solution can be sprayed 2 times, and then sprayed again every 10 days and 15 days. During the onset period, it can be sprayed according to the instructions, and the front and back sides of the leaf can be sprayed evenly, sprayed once every 7 days and 10 days, and used fungicides alternately.

Cultivation method steps:

1) Planting.

1. Cleaning impurities: Use sterilized scissors to cut off diseased roots and rotten roots, and clean up orchid roots, leaf nails and leaves. Clean up the planting site of weeds and impurities.

2. Disinfection: The planting material is exposed to the sun for more than 3 days for disinfection, and it can also be soaked and disinfected with bactericidal and insecticidal solutions such as methyl tobuzin. Soak the orchid seedlings with fungicide for 20 min and 30 min according to the proportion of use, take out the orchid seedlings to dry, and then put them on the pot after the orchid roots are soft.

3. Cushion pot: The trap should be placed at the bottom of the pot in advance, and the optional coarse planting material should be placed at the bottom of the pot, and the thickness should be one-third of the pot height.

4. Planting: Comb the root group and slowly fill the pre-prepared middle layer planting material into the pot. Put the false bulb low, and slowly raise the orchid plant with the planting material filling, and shallow planting is appropriate.

5. Paving: After the orchid plant is finalized, cover less than two-thirds of the false bulb with fine planting material. The pot surface can be covered with green cloud grass or water moss to moisturize and keep the orchid plant warm.

2) Watering.

2. Humidity: The humidity in the air is low, so you should water more; Conversely, if the humidity is high, water less.

3. Temperature: The number of watering increases accordingly when the temperature is high, and the number of watering decreases on the contrary.

4. Season: more watering in summer, less or no watering in the rainy season, less watering in the winter when the temperature is low, less watering in the early spring when the temperature is lower, more watering in the late spring when the climate is mild, and more watering in the dry autumn.

5. Weather: watering more on sunny days, less watering on cloudy days, and no watering on rainy and snowy days.

3) Fertilization.

1. Base fertilizer: It is advisable to choose slow-release orchid special fertilizer or organic fertilizer and mix it into the substrate.

2. Top dressing: there are two kinds of root irrigation and foliar spraying. Root irrigation mainly adopts watering type and spray type; Foliar sprays should be sprayed with water-soluble liquid fertilizer.

4. Light: full light can be accepted in spring, the shading rate should be more than 70% in early summer or autumn, and more than 80% in summer.

5. Temperature: The suitable temperature for the growth of Cymbidium is 20 30. Day temperature 10 Night temperature 5 10 is the dormant period of winter. Orchid-4 is the limit of low temperature tolerance. The vernalization temperature is 0 5.

6. Humidity: The relative humidity suitable for growth is 60% to 75%.

1. Soil. When cultivating orchids, it is necessary to use loose, breathable and fertile soil, so that its roots can better breathe and absorb nutrients and water in such a soil environment. You can mix the soil with humus and river sand. You can also go to the flower shop to buy special nutrient soil.

2. Temperature. The most suitable temperature for Whelan is around 10 25, so in winter, it is best to place it in a warmer indoor culture. And in the winter, because of the cold weather, it will grow more slowly.

Broad Blade Balance Base God.

3. Ventilation. Most of the native Whelan grows at higher altitudes, so it has certain requirements for the ventilation of the environment. It is best to place it in a place with more permeable air when breeding, which is conducive to the growth of Whelan, which is an important point in the cultivation method of Huilan.

4. Fertilization. The fertilizers used to breed Whelan are mainly phosphate fertilizers and potassium fertilizers. And because Whelan is relatively tall compared to other flowers, the root system is also thicker.

Therefore, in the process of breeding Whelan, you can apply more fertilizer in an appropriate amount. The frequency of fertilization is generally about once every 10 days.

5. Watering. In the process of cultivating orchids, the demand for water is large. Especially in the summer, the water evaporates faster.

The frequency of watering will be more frequent, generally about 2 3 days at a time, and each time you do watering carefully, you need to water the soil completely to a moist state. The foliage also needs to be sprayed with water from time to time to cool and humidify.

Its root system is usually fleshy, and the requirements for the soil are loose, fertile and have good drainage. If you use garden soil or sandy soil directly, it is difficult to raise vigorously. In addition, it also has requirements for pH, which needs to be acidic to meet these needs in order to grow well.

When planting, it can be prepared by itself, mixed with mountain soil, coarse-grained river sand and perlite, so that it can match its growth characteristics. However, in recent years, the southern region has been prepared with peaty soil and perlite, and the ratio is 4:1, which is very beneficial to its growth, but the price is more expensive.

In addition, it can also be prepared with peaty soil, river sand, and then mixed with an appropriate amount of organic fertilizer, and the growth is also relatively vigorous.

When planting, in addition to the soil, you should also pay attention to the method of potting. Drainage must be considered when basinding, and the bottom of the basin should be filled with holes and gaskets. The gasket should be thick and more, and then the gravel and sand grains should be paved on top, and then the plant should be placed in the pot, and an appropriate amount of potting soil should be added, which is more conducive to drainage and ventilation, and the plant can grow better.

Hello, no, winter socks are generally moved indoors in the season, otherwise it is easy to freeze to death. When the large flower is cultivated outdoors in the southern region, it can be allowed to spend the winter in the open field, and in the northern region, it needs to be moved to the temperature higher than 10 degrees in the state of the state for maintenance, so as not to freeze to death.

1. Soil conditions, Whelan is a kind of orchid, and when breeding Whelan, the requirements for soil are relatively high. It is necessary to use flower soil with good air permeability to cultivate, so as to ensure the respiration of the roots and avoid root rot. If it is convenient, you can directly buy the special soil for orchids on the market, and you can also mix it yourself if you have time.

Generally, nutrient soil, pond cornerstone, weathered rock and granular yellow mud are selected, which can be according to 5:3:1:

1 ratio collocation.

2. Appropriate temperature, for novices, the most difficult thing to control is how to raise Whelan is the temperature. The plant prefers a warm environment, and the optimal growth temperature is between 10-25, if the temperature is too high, it will be detrimental to growth. At the time of flowering, it is necessary to keep the temperature between 5-15 to make the flowering period longer.

3. Light conditions, Hui orchid prefers a strong light environment, and it is recommended to place balconies or window sills with sufficient light when cultivating at home, so as to make it more fully photosynthetic. However, in the environment of high temperature and scorching sun in summer, it is still necessary to have proper shade, if it is exposed to strong light for a long time, it is easy to have yellowing and wilting leaves, which affects the growth and development of plants.

4. Watering method, although Whelan likes a moist environment, but is still afraid of standing water. Generally speaking, Whelan can be watered in small amounts and many times to keep the soil slightly moist, and the amount of water at one time should not be too much. When the temperature is high, due to the large amount of evaporation, you can spray water on the plant to moisturize and maintain a reasonable humidity.

5. Reasonable fertilization, fertilization is a very critical part of raising Whelan, but fertilization does not need too much. It is recommended to use Orchid King, which can be sprayed every ten days during the growing season. In addition, at the beginning of March and early October of each year, a fully diluted decomposed organic fertilizer should be applied respectively.

Some whelans are not easy to bloom and can be sprayed with a concentration of potassium dihydrogen phosphate solution from August to November each year.

6. The best time period for changing the potting soil is between March and June each year, generally selected on a sunny day, if it is rainy weather, it is not suitable for replacing the potting soil. During the replacement process, it is important to check some of the Whelan roots, and if there are rotten parts, they can be pruned properly, so that the plant can grow healthier in the future.

1. Soil. Hui orchid is a semi-aerial root flower, and acidic soil containing humus and good air permeability should be used. It can be configured by itself, mixing 70% sandy loam + 30% coarse-grained humus soil, and used after disinfection and sterilization; You can also buy special soil online or at the market.

2. Temperature. Hui orchid prefers warm winters and cool summers, and the growth temperature is 10-25. In summer, the temperature is high, and the orchid spray should be properly sprayed to cool down; In winter, the temperature is low, and the temperature is between 2-3 to move indoors for wintering.

3. Illumination. Hui orchids love strong light and can withstand strong light from 50,000 to 70,000 lux. From March to April, you can bask in the sun, from the end of April after 9 o'clock in the morning, it is not advisable to bask in the sun, from June to September, you should shade early every day, and you can postpone the shade after October.

4. Watering. The principle of watering is that it should be dry and not wet", you can use river water, spring water, well water, pH value 5-6, do not get wet. Water once a week in January and February, every 3-4 days in March and April, every 2 days in May, once a day in June, every 3 days in July and August, and gradually reduce from twice a day to once a week from September to December.

5. Fertilization. The principle of fertilization is thin fertilizer and frequent application", generally in May before the new grass is unearthed, to stop in the beginning of autumn, fertilization every 15-20 days, fertilization in the evening. More than 10 times a year to apply fertilizer to the orchid, there are Su fertilizer, germination fertilizer, flower sprout fertilizer, growth fertilizer, flower fertilizer, confinement fertilizer, cold-resistant fertilizer, dowry fertilizer, Cui root fertilizer, each fertilizer once or twice Zen bush.

The fertilizer must be thin, otherwise it will hurt the leaves and roots.

1. Soil: When cultivating Hui orchids, it is necessary to use peat, river sand, and humus soil to prepare a cultivation substrate. 2. Light temperature:

Place the orchid at 15-25 degrees Celsius to avoid poor growth. 3. Watering: Hui orchid is not resistant to waterlogging, so it can be watered every 1-2 weeks.

4. Pruning: After the orchid blooms, it is necessary to cut off the broken flowers immediately.

1. Prepare the soil

Choose a suitable pot according to the size of the planted orchid, and mix the peat, river sand, and humus soil to make the base soil and fill the pot. In addition to ensuring that the basic requirements such as soil looseness and ventilation meet the standards, the pot and soil should be changed every 2 or 3 years.

2. Light temperature requirements

In the environment of 15 25, Hui orchid can grow very vigorously, and the stable temperature is above 5 during the winter to avoid frost damage. Place the plants on a balcony with plenty of diffused light to receive nourishment, and do a good job of shielding them from strong light in summer.

3. Reasonable irrigation

Watering too often is easy to accumulate water and rot roots, so watering ensures that the potting soil is not dry and watered, and watering is thorough, and the amount of water is controlled. Compound element fertilizer is applied once before and after the flowering period, and top dressing is applied before summer and winter to ensure timely nutrient supply.

4. Prune after flowering

Different varieties of orchids bloom in spring and autumn respectively, and the flowers are large and colorful, and there are always old and weak branches that are crippled due to being robbed of nutrients every time they bloom. Farmers need to prune in time to avoid pests and diseases after rotting.
