How to Plant Camellia oleifera How to Plant Camellia oleifera

1. To prepare for planting Camellia oleifera, we must first investigate and select afforestation sites. Choose soil. Although Camellia oleifera is barren-tolerant, yes, fertile soil is still one of the conditions to create high yield. Choose a sunny slope with a slope less than 25 degrees. Soil, including metamorphic rocks, sandstone, granite, yellow red soil, yellow soil and weathered red loam. Generally speaking, the thicker the soil, the better. The thickness of the soil layer should not be less than one meter.

2. Cultivate seedlings. Camellia oleifera seedlings have relatively high demand for nutrients. Under the condition of sufficient organic fertilizer and nitrogen fertilizer, the seedlings grow well and take root quickly. Proper supplementation of phosphate fertilizer and potash fertilizer is easy to form strong seedlings. In summer and autumn dry season, timely watering is very beneficial to the growth of Camellia oleifera seedlings. When the rainy season comes, we should also pay attention to flood control. Generally, it takes 4-5 years from planting seedlings to generating income, which takes a long time and requires a lot of continuous investment. Therefore, before there is no economic benefit, reasonable arrangements can be made in the Camellia oleifera forest, and leguminous plants can be planted without affecting the growth of Camellia oleifera, so as to alleviate the dilemma of capital investment. Weeds should be removed in time to avoid affecting the growth of Camellia oleifera.

3. Cultivate a reasonable tree shape. Cultivate normal and strong lateral branches into trunk. Leave lateral buds on the main stem next year and cultivate them into lateral branches that can bear fruit in the future. When pruning, try to recreate branches harmful to pests and diseases and overlapping branches. Try to leave the fruiting branches and spring shoots in the inner room. Camellia oleifera is characterized by the need for fertilizer. In the young tree period, it is mainly to plant trees. In thinking, it pays more attention to nitrogen fertilizer. In the flowering and fruiting period of Camellia oleifera, the contents of phosphate fertilizer and potassium fertilizer should be appropriately increased, and boron fertilizer should be applied in combination.

4. Control of pests and diseases of Camellia oleifera. Diseases and pests of Camellia oleifera are mainly prevented, supplemented by treatment. Pests are generally cultivated as natural enemies of camellia oleifera pests. When spraying pesticides, try not to spray pesticides harmful to natural enemies. Generally spraying pesticides and using biological agents as far as possible are very beneficial to protect the natural enemies of pests such as red ladybug and black-edged ladybug. Camellia oleifera has general pests and diseases. Soft rot, anthracnose, bituminous coal disease. Pests include scarabs, tea caterpillars, sawflies, weevils, tea-pointed moths, longicorn beetles, borers, weevils, ant frogs and so on.

5. Precautions for harvesting Camellia oleifera. Generally, camellia oleifera is harvested twice, once in the cold dew season. This time, it is only suitable for picking cold dew seeds, not for picking first frost seeds. You can pick first frost seeds after the first frost. Proper picking can improve the oil yield, so we must grasp it well.
