How to raise millions of small bolls Culture methods and matters needing attention

Millions of small bell, also known as small flower petunia, is a kind of plant with flowers as the main ornamental spot. at present, it is distributed in many parts of our country, and it is a common flower variety. Now there are a lot of people who want to raise millions of small bell, but many people don't know much about the specific breeding skills. Next, let's study together.

How to raise millions of small bell

1. The best propagation time: millions of small boll cuttings can be carried out in winter.

2. The best growing soil: millions of Xiaoling likes fertile and loose humus soil, so that it can take root faster.

3, growth humidity requirements: summer high temperature season to timely replenish water, in addition to timely delivery of water, very good foliar spray water.

4. The optimum growth temperature: the optimum growth temperature of millions of small bolls is between 15 °C and 30 °C. it can withstand the low temperature of zero for a short time in winter and the high temperature of 35 degrees in summer.

5. The best growth light: millions of small bolls grow better in the sunny environment, and can grow normally in the semi-shady environment.

Culture methods and matters needing attention of millions of small bolls

1. Culture methods:

1. Transplant. The transplanting ability of millions of small bolls is relatively poor, and if the root takes a long time to recover after injury, it will be difficult to save the serious one, so the best time to transplant is after the small pot root is full, we must pay attention to avoid root injury when transplanting. After successful transplanting, it takes a week to slow down the seedlings, first put in the shade, the leaves need to be sprayed sooner or later, and then moved to the all-day environment to cultivate.

2. Fertilization. Millions of small bolls do not need much fertilizer for growth, and the preparation of base fertilizer can be less. It can be allocated according to the ratio of earthworm fertilizer to soil (1:3). Thin fertilizer should also be applied during the growing period, and the frequency of application can be increased.

3. Sunshine is fully beneficial to the growth of branches and the increase of flowering number, pay attention to replenish water at high temperature in summer, and the leaves also need to be rehydrated after dehydration leads to wilting of stems and leaves.

2. points for attention:

In general, you can plant three million small bolls in a flowerpot, because Xiaoling has a large number of flowers, so planting one plant is fine. A reasonable coring method can make a plant grow beautiful bouquets. If you choose small bolls of different colors for planting, you need to consider how to match them according to different plant characters.

The heart-picking method of millions of small bells

Generally speaking, the first coring can be carried out when the height of the seedling grows to 6-8 cm. Generally speaking, the temperature is high in summer, the plants grow fast, the internodes are longer, pick the heart frequently, leave fewer leaves after picking the heart, usually leave 4-6 leaves after picking each branch, plant growth is relatively slow in spring, the internodes are relatively short, leaving 6-8 branches after coring, no more than 10 leaves. If there are more branches in some places, the corresponding coring can be carried out several times, leaving only 2-3 leaves each time, so that the unsatisfactory places can continue to grow to improve the plant type.

Common diseases and insect pests of millions of small bolls and their control

1. White mildew. After the onset of the disease, the diseased leaves were removed in time, and 75 {bf} chlorothalonil was sprayed at the initial stage of the disease.

2. Leaf spot. Try to avoid bruising leaves and pay attention to prevent wind injury, sunburn and freezing injury; timely removal of diseased leaves and burning, pay attention to remove fallen leaves; spray 50 {bf} 1000 times solution.

3. Virus. The indirect control method is to spray insecticides to control aphids and spray 40 {bf} omethoate 1000 times solution; in the cultivation operation, tools and hands that have come into contact with diseased plants should be disinfected.

4. Aphids. When a large number of aphids are found, they should be isolated in time and sprayed with 10 {bf} omethoate emulsion 1000 times or Mala sulfur emulsion 1000 times or dichlorvos EC 1000 times or 70 {bf} imidacloprid 15000 times.

Millions of small bolls in breeding must pay attention to temperature control, the temperature is too low may lead to plant death. Light is also an important condition affecting its growth, timely lighting is conducive to its flowering, in the later stage of culture, but also for the prevention and control of diseases and insect pests, only in this way, millions of small bolls can grow healthily.
