What to do with the growth of Chrysanthemum morifolium? pest control of Chrysanthemum morifolium / 2 insect pests 2 diseases

When we cultivate chrysanthemum, the last thing we want to encounter is diseases and insect pests. This kind of problem is very harmful to the plant. It will not only affect the ornamental property, but also cause the plant to die when it is serious. What should we do if the chrysanthemum grows insects? What does the pest control of Tianrenju need to do? The following small series takes everyone to understand.

I. What should I do if the chrysanthemum grows worms? Find out the reason.

If you want to know what to do with the long insects, first of all, we need to know what kind of insects they grow, so that we can carry out targeted treatment on them, because the treatment methods of each pest are different. The specific details are described in detail below. Friends who have problems in this area can come to know about it.

2. Prevention and control of diseases and insect pests of Tianrenju

1. aphids

Aphids are the most harmful pests among the plant diseases and insect pests. They mainly harm the leaves, stems, tender heads and tender ears of the plant. They will gradually absorb the sap, resulting in a large loss of nutrients and a gradual death of the plant.

Prevention and control methods: aphids against this kind of chrysanthemum pests, if the number is small, we can carry out artificial killing, see a pinch a. If the quantity is large, we can use 40% imidacloprid water solvent 1500~2000 times solution to spray.

2. the beetle

Scarab is a kind of invertebrate, it mainly damages the roots, leaves, buds of chrysanthemum, thus affecting the yield and quality of flowering, and even causing the plant not to bloom when it is serious.

Control methods: We can use 2.5% deltamethrin 2000-3000 times solution to spray it when dealing with this kind of insect pest, or we can trap it under light.

3. rust

Rust is one of the most common diseases and insect pests of chrysanthemum. This disease mainly threatens the leaves, stems and fruits of plants. When it is infected, many small blisters will appear on the affected parts. When it is serious, the blisters will be concentrated into pieces, and the plants will die quickly.

Control method: When rust appears on Tianren chrysanthemum, we can use 50% chlorhexidine wettable powder 2000 times solution to spray it, generally spraying once every 7-10 days, 1-2 times can cure it.

4. black spot

Black spot is a disease caused by fungi. Many black spots appear on the leaves of Anthema chinensis when the disease occurs, and the spots will gradually spread over time, eventually leading to the gradual death of the plant.

Control methods: In the prevention and control of this kind of insect pests, we can use 7% Tobucine 800 times solution to spray it, generally spraying once every 7-10 days, 2-3 times can be cured.

How to breed, how to breed

Chrysanthemum is a kind of flower plant originated in tropical America, and later introduced to China. Now it can be seen in many parts of China. As more people breed it around, people are more concerned about its reproduction. How does it reproduce? What are the reproductive methods of the heavenly chrysanthemum? The following small series takes everyone to understand.

How to breed, sow/cut

When it comes to how to breed chrysanthemum, in fact, it is mainly divided into two methods of sowing and cutting propagation. Sowing and propagation are generally carried out in summer, while cutting propagation is more appropriate in spring and autumn. As for how to operate these two propagation methods, there are detailed introductions below. Let's take a look at it.

2. The reproduction mode of Tianrenju

seed reproduction

Seed stimulation: before we sow and reproduce the chrysanthemum, we first need to stimulate its seeds. We can soak the harvested seeds in warm water for about 3-10 hours. When the seeds begin to absorb water and expand, we can take them out and sow them. This can improve the germination rate of seeds.

Sowing method: In the breeding method of Tianrenju, sowing and breeding is a common method. First of all, we should apply appropriate amount of base fertilizer in the pot soil before sowing, and then evenly sow the seeds on the soil surface. After sowing, cover 1-2cm of soil on it and water it. It is best to use the dipping pot method when watering, because the seeds of Tianrenju are relatively small. If you water them directly, it is easy to wash them away.

cutting propagation

Cutting selection: before cutting propagation of chrysanthemum, we need to choose the right cutting, this is a very important step, we had better choose the growth of more robust and pest-free branches as cuttings, so the survival rate will be very high, if we choose to look very small and delicate branches, then the basic can be declared cutting failure, survival rate is not very high.

Cuttage method: In the breeding mode of chrysanthemum, the operation of cutting propagation is relatively simple, before cutting, we can first use chopsticks to insert a hole in the pot soil, and then insert the cuttings into it, so that the operation can avoid cutting damage, it is very practical. After the cuttage is completed, we should also pay attention to light management. The stronger the light, the higher the temperature in the cuttage body and the more water consumed, which is not conducive to the survival of the cuttage.

follow-up management

After we successfully reproduce according to the above methods, we can carry out daily maintenance on them. There are also many places to pay attention to in terms of maintenance, such as watering, fertilization and other aspects. If you don't know how to raise them, you can refer to the article on the cultivation method of Tianrenju, which has detailed teaching.

When to sow, how to plant/substrate disinfection/pre-seed urging

Among the breeding methods of chrysanthemum, sowing and breeding is a more commonly used method. This method has been tested by countless people and still has a high survival rate. However, if we want to sow successfully, we need to pay attention to many points. When will chrysanthemum be sown? How do you plant the seeds? The following small series takes everyone to understand.

When to plant seeds in summer.

When it comes to when to sow chrysanthemum, it is very important to choose the right time. This plant likes high temperature environment, so we can sow it in summer, because the climate of this season is more suitable for its growth, so the survival rate will be relatively high.

2) How to plant seeds carefully.

As for how to plant the seeds of chrysanthemum, there are many places we need to pay attention to, such as the selection and disinfection of the substrate, the promotion of seeds and other aspects are more important, of course, the most important thing is to operate carefully, as for the specific planting technology in the following detailed introduction, interested friends can come to know.

1. substrate selection

Before we plant chrysanthemum, we first need to choose the substrate, this is a good foundation step, is very important, generally it is best to choose loose fertile humus soil, this plant is rich in nutrients, and drainage and permeability are very good, can make the plant better absorb nutrients, also not easy to appear ponding phenomenon.

2. substrate disinfection

After we select the soil, we also need to disinfect it, so as to prevent pests and diseases from spreading to Tianrenju. When disinfecting, we can choose to scatter it and spread it in the hot sun for disinfection, or put it into a pot and stir fry it, so that if there are pests in the soil, they will also be killed.

3. seed stimulation

Before we plant the seeds of chrysanthemum, we also need to stimulate their seeds. We can soak the harvested seeds in warm water for about 3-10 hours. When the seeds begin to absorb water and expand, we can take them out and sow them. This can improve the germination rate of seeds.

4. planting method

When planting chrysanthemum, we should first apply appropriate amount of base fertilizer in the pot soil, and then spread the seeds evenly on the soil surface. After sowing, cover 1-2cm of soil on it and water it. It is best to use the dipping pot method when watering, because the seeds of chrysanthemum are relatively small, and it is easy to wash them away if watering directly.
