II. Pest control of Begonia nigra

1. the beetle

Scarab is a soil-dwelling pest, which is a common pest among the pests of Malus hirsutus. This pest mainly feeds on the taproot and stem of Malus hirsutus. It will gradually eat the bottom of the plant, resulting in incomplete plant and death.

Control method: When dealing with this pest, we can spray 40% omethoate 1000 times solution on the soil, loosen the topsoil after spraying, so that the solution can penetrate better, and this pesticide will die when touched.

2. aphids

Aphids were a kind of plant-feeding insect. They were very destructive to the West Mansion Begonia. They would attach to the back of the leaves of the plant and gradually suck the juice from them, causing a large loss of nutrients from the plant. The leaves would slowly turn yellow and dry up. In severe cases, they would also cause the plant to die.

Control methods: aphid is a plant with strong reproductive ability, so we must control it in time when we find it. The most direct way to deal with this pest is to spray it directly with 50% aphimid-resistant WP 3000 times.

3. red spider

Red spider, also known as cotton spider, is a pest of Tetranychus family. The size of this pest is very small and it is generally difficult to find. Its harm way is to pierce the leaves with mouthparts to suck the juice, which leads to the destruction of chlorophyll and yellowing phenomenon, and in serious cases, it will also lead to leaf shedding or even light loss.

Control method: When dealing with this kind of disease and insect pest of Xifu Begonia, if only individual leaves are injured, we can remove them. If more leaves are injured, we can use 40% dimethoate emulsifiable solution 1500 times to spray on the plants to eliminate this pest once.

4. white star disease

White star disease mainly threatens the leaves of Malus xifuensis. Many dark brown spots will appear on the leaves when the disease occurs, and then the periphery will be dark brown and the center will be gray. This disease mostly occurs on the lower leaves, and when it is serious, the leaves will also appear curly and dry.

Control methods: For this kind of disease and insect pests of Xifu Begonia, we can use 75% chlorothalonil wettable powder 500-800 times to spray the diseased plants, generally every half month or so, 1-2 times after it can be cured.

5. canker

Rot disease is a disease caused by fungi, which can infect young seedlings and attack in flowering stage. It can occur on flowers, fruits, leaves and stems of Malus hirsutus. If this disease is not treated in time, it will lead to gradual withering and death of plants.

Control method: When we deal with this kind of disease and insect pests of Xifu Begonia, we can use 40% Pythium WP 15- 20g to apply medicine to the diseased plants, usually once every 3-5 days, 2-3 times later, it can be cured.

After sowing, cover 1-2cm of soil on it and water it. It is best to use dipping pot method when watering, because its seed volume is small, and it is easy to wash away the seeds if watering directly from above.

division propagation

When we carry out plant division propagation of Xifu Begonia, we can combine it with pot change, and the time can be selected in spring. When dividing plants, we should take out the mother plants that grow too densely from the pot soil, and then divide them into several clusters, which are respectively potted and planted with them. It is easy to survive. Generally, after the pot is a complete pot of flowers.

grafting propagation

Grafting propagation is mainly suitable for fine varieties of Xifu Malus, we can select their branches as scions, and then cut and split in spring, and abut in the growing season. The grafting method can be carried out according to the grafting method of general woody plants.

In order to make Xifu Begonia flower colorful and beautiful, we need to adopt:

① Timely pruning: pruning too dense and thin branches, dead branches and diseased branches before germination in early spring every year, which is beneficial to ventilation and light transmission, promotes growth and flowering, and reduces the occurrence of diseases and insect pests; for old plants, old branches shall be renewed, and the upper ends of large branches with few branches shall be cut off with sharp saws in grass spring. After germination of new branches, several strong branches shall be selected, and thin and weak branches shall be cut off, and flowers shall be allowed after 1 year of cultivation.

② Fertilizer and water management: planting before germination of early spring buds, applying decomposed organic fertilizer before planting. After falling leaves every autumn, dig ditches in the rhizosphere and apply decomposed organic fertilizer, and irrigate thoroughly after covering soil. Adult plants should not be watered more, more water easy to produce yellow leaves. Generally, water is poured 2-3 times in spring, 1-2 times in summer and autumn, and 1 time in winter.

③ Timely fruit picking: young fruits should be picked in time after flowering, saving nutrients and increasing the number of flowering in the coming year.

④ Disease and pest control: Xifu Begonia is vulnerable to aphids, red spiders, scale insects, longicorn and other pests, so it is necessary to spray timely for control.
