1, planting Camellia oleifera requires sufficient sunshine, otherwise it will only grow branches and leaves, with poor effect and low oil content. At the same time, it needs enough water; It's warm and sunny in spring, so it's best to plant Camellia oleifera in low hills with open terrain, so that the roots of Camellia oleifera can grow firmly in deep soil.
2. Because Camellia oleifera has the biological characteristics of blooming in late autumn and early winter, and the flowers and fruits keep growing all the year round, the disastrous climate such as autumn drought and cold wave has great influence on its flower and fruit growth and yield. Therefore, Camellia oleifera should be planted in warm and abundant rainfall areas, and the optimum temperature of Camellia oleifera is 14 ~ 18℃. This climatic condition is beneficial to insect pollination, pollen germination and fruit conception of Camellia oleifera. However, abnormal weather such as low temperature and rainy weather occurred during this period, which led to a large number of flowers and fruits falling and reduced production.
3. Need enough water. Although Camellia oleifera has certain drought tolerance, it needs sufficient water supply and reasonable and balanced water conditions in its growth and development process, especially in the fruit growth process, in order to meet the needs of its physiological activities and substance synthesis and transformation. Camellia oleifera likes acidic and slightly acidic soils, but it is not suitable for neutral or alkaline soils.
4. The soil should be fertile and the root system of Camellia oleifera is deep, which is suitable for deep soil cultivation. The common characteristics of soil in high-yield camellia oleifera forest land are: good structure, mostly fertile soil; Soil has high nutrient content and large reserves of main nutrients.
5. Seed selection: When collecting Camellia oleifera seeds, we should pay attention to four levels: film selection, plant selection, fruit selection and selection, and choose fresh and high-quality seeds with large and full seeds, dark brown seed coat, no diseased spots and no luster. Do not pile, degum or expose to the sun after picking. It should be spread in a ventilated and dry place to make it naturally crack and thresh, and the seeds should be stored in a cool place indoors.
6. Reasonable planting. Camellia oleifera planting time is generally 10 and February every year. At this time, the survival rate of Camellia oleifera planting will be higher than that of flat planting. If the soil is barren, the spacing between plants should be large, if the soil is fertile, the spacing between plants should be small.
7. learn to trim. During the growth of Camellia oleifera, not all fruits will grow due to environmental factors, and some obvious bad fruits will appear in the middle. When growing, its growth will be abnormal due to factors such as light and terrain, and a bunch of useless branches will appear around it. Pruning is a key point to pay attention to when planting Camellia oleifera. Pruning miscellaneous branches, rotten fruits and old branches can greatly prolong the life of Camellia oleifera in full fruit period.
