The breeding methods and matters needing attention of du Ying flower of Malvaceae? Disease and its control? What's the use?

Elaeocarpus sylvestris L., mostly born in the mountain forest below 1000m above sea level, so the cultivation methods and precautions of Elaeocarpus sylvestris L. Disease and its control? What does it do? According to information, Elaeocarpus sylvestris likes warm and humid growth environment, can withstand shade, but not cold. It prefers moist, fertile, well-drained soil and grows faster.

1. Cultivation methods and precautions of Elaeagnus angustifolia?

soil

Elaeocarpus sylvestris likes warm and humid environment, suitable for growth in acidic soil, high requirements for soil, need moist fertile and good drainage soil,

fertilization

At the beginning of the growth of Elaeocarpus sylvestris, it is recommended to use thin natural fertilizer, and then urea solution can be selected for nutrient supply.

herbicidal

In order for Elaeocarpus to grow better, weeds need to be removed in time. Doing so allows Elaeocarpus to absorb water and nutrients better, preventing other weeds from competing with it.

precautions

Elaeocarpus sylvestris grows faster, so we should pay attention to reasonable water and fertilizer. At the same time, Elaeocarpus sylvestris has strong resistance to sulfur dioxide. Elaeocarpus oleifera to the growth of vigorous period, but also in time to do a good job of thinning seedlings.

Disease and its control?

blight

The main symptoms after the disease: leaf spots or dead leaves. After the occurrence of leaf blight, corresponding measures should be taken in time, and drugs can be selected for treatment. Xuezebutozin wettable powder, or kill Kujing wettable powder, chlorothalonil and other agents to spray, eliminate patients.

damping-off

The main symptoms after the disease: Elaeocarpus sylvestris plants suddenly lodging, plants appear dark brown. Damping disease is mostly caused by the invasion of bacteria. The pathogen invades the rootstock of the seedling through the soil, causing the seedling to lodge like the ground. This is what we call cataplasia. In addition, lignified plants show different signs of disease than seedlings, mostly withered, and if the growth environment is wet, pink colonies of bacteria will be produced at the site of the disease.

For the seedling disease, it is suggested to use drug treatment, spraying thiophanate-methyl WP, dexone and other agents, sterilization. Because damping-off disease is infectious, in order to reduce losses and better control the disease, the diseased plants should be disposed of in time to prevent infection of healthy plants. All diseases should be prevented from the very beginning. For this reason, it is recommended to disinfect the soil during the initial planting period to kill germs.

Seedling damping-off is caused by Rhizoctonia solani in the soil. Pathogens mostly invade the root base of seedlings from the surface soil. After the plant is injured, the diseased part sinks and shrinks, showing dark brown. The infected seedlings often lodge from the soil surface, causing damping-off phenomenon (so-called damping-off disease); if the seedling tissue has lignified, the diseased seedlings often do not lodge and show symptoms of standing and withering. When the soil layer is wet, pink mold layer is often produced in the diseased part.

sunburn

Sunburn is caused by external factors, the incidence of the performance of cracks in bark wood, easy to break when windy weather. Preventive measures are mainly to pay attention to planting density when planting, and the distance should not be too far. And protect the trunk of the tree from exposure, the feasible way is to use straw rope to wrap the trunk for protection.

III. What role does it play?

Garden Ornamental of Elaeocarpus sylvestris L.

Elaeocarpus sylvestris has certain ornamental value. It has dense branches and leaves, some of which turn red after frost.

Elaeocarpus sylvestris is suitable for planting in lawns, slopes, etc., in courtyards, roads, and as background trees for other trees.
