How to sow and reproduce of Compositae

Bee cod, also known as Donghua, Dudong, so how to grow and breed bees? What's the impact? Pests and their prevention and treatment? According to this information, a bee-eater is a plant that likes a cool environment and needs some air moisture. When choosing soil, you should choose loose and fertile soil and be careful not to be too dry. Keep the temperature appropriate when breeding beehives, but don't get too high in summer and be careful not to exceed 35 °C. When planting, it must be fertilized in advance to make it grow better.

First of all, how to sow beetroot for breeding?

Soil

When beekeeping, should choose half-shade, half-yang, moist, slightly acidic sandy loam, soil drainage should be good. After selecting the cultivation site, the soil can be fertilized and the soil can be ploughed deeply.

Cultivation and weeding

When planted in spring, the seedlings will grow in the first half of April and can be replenished at the same time during good cultivation and weeding. At this time, the root growth of the seedling is relatively slow, so shallow soil should be used to avoid destroying the root of the seedling.

In June and July, the seedlings have been released and the roots have grown well. At this time, a good secondary culture can be carried out.

At the beginning of September, the stems and leaves of the plant gradually stopped growing and the buds began to differentiate. At this time, after the third culture, the weeds were not maintained.

Interplanting

After releasing seedlings at the end of April and early May, seedlings can be properly planted according to emergence, leaving strong seedlings and removing weak plants.

Topdressing and breeding soil

Butterburst does not need to be done in the early stages of growth to avoid overgrowth. In the later stage of growth, it is necessary to strengthen the management of topdressing. Topdressing should be combined with loose soil, one side should be covered with fertilizer, and the roots of the plant should be used to maintain the fertilizer effect of the soil.

Watering

Bees and cod are afraid of drought and phlegm. When it is dry in spring, it should be watered two or three times in a row. When the rainy season comes, it is necessary to prepare drainage.

Blade cutting ventilation

The butter exploded during the leaf period from June to August. Too dense leaves, poor ventilation and poor light transmittance will affect the flower bud differentiation of plants, but also lead to diseases and insect pests. At this point, you need to clean the overlapping leaves with scissors and avoid damaging the base of the plant when rubbing with your hands.

Good. What's the role?

1. Detoxification effect

First of all, it can eliminate some poisons in the body, treat poisoning after being bitten by snakes, and expel harmful substances from the human body.

2, germicidal efficacy

Butterburry contains an element that can mitigate the effects of cockroaches. Not only that, it can also eliminate some fungi in the mouth, promote cilia movement in the trachea, treat mucus secretion in the trachea, reduce the risk of coughing, and treat bronchitis and other diseases.

3. Analgesic effect

Butterbur is a cool plant that tastes bitter, but it can help reduce toxins, remove body bruises, eliminate swelling and pain caused by bruises, and have a good effect on tonsillitis, bruises and other symptoms. .

4. Antitoxic effect

There is caffeic acid in beedol, which can inhibit the proliferation of bacteria, weaken their activity, and effectively treat acne on the face. Not only that, but also can treat colds and inflammation. It has good control effect on bacteria such as Staphylococcus aureus and Shigella dysentery. In addition, it can also treat cataracts caused by diabetes.

5. Taboo

Although bee fighting vegetables have more benefits, they cannot be used under any circumstances. For people with relatively cold spleen and stomach and relatively thin feces, it is better not to use this plant too much.

Third, diseases and insect pests and their prevention?

Brown spot of beehive and its control

Symptoms of brown spot: Brown spot mainly damages plant leaves, and the disease spots on the leaves are round or nearly round, and summer is the middle stage of the disease.

Prevention and control of brown spot: remove diseased and morbid strains and spray Bordeaux liquid in the early stages of the disease. Spray every 7 to 10 days, several times in a row.

Dead leaf disease of beehives and its control

Symptoms of dead leaf disease: mainly damage to the leaves of the plant, the lesion extends inward from the edge of the leaf, the lesion is a black irregular spot. When the leaves are infected, they become brittle, causing the leaves to partially or completely dry and spread to the petiole.

Control dead leaf disease: remove infected dead leaves and spray Bordeaux solution.

Beetle aphids and their control

Aphid symptoms: aphids can absorb plant stem and leaf juice, which can cause stems and leaves to turn yellow in severe cases.

Locust control: in winter, gardens are cleaned and dead plants and fallen leaves are buried or burned. In the early stages of the disease, spray killed pine trees and spray them for seven to ten days.

White cockroach of beedol and its prevention and treatment

Symptoms of chalk: water-stained lesions appear in the roots of diseased seedlings or adult plants. When the lesion spreads, small white sclerotia form and gradually turn dark brown.

Prevention and control of chalk disease: strengthen cultivation management and choose to plant in high arid areas; carbendazim and methyl topiramate can be used for prevention and treatment.
