During the high-yield period, the planting density of Camellia oleifera per mu is about 90 plants. The yield of Camellia oleifera seeds per mu is about 150kg-200kg, and the yield of camellia oil per mu is about 30kg-50kg. Planting methods: 1. Choose improved varieties: Choose varieties with the same flowering cycle, large fruits, thin skin, more oil, and strong resistance. 2. Land selection and preparation: The soil should be acidic, fertile red or sandy soil. 3. Reasonable planting: suitable for planting in February or October. 4. Scientific fertilization: Nitrogen fertilizer should be applied during the seedling stage. 5. Field management: Cultivating and weeding should be carried out three times a year.

1. How much yield per mu of camellia oleifera can generally be achieved

The fruit-bearing time of camellia oleifera is generally 3 years, and the high-yield time is generally 7 years later. The better-cultivated camellia oleifera trees will be in the high-yield period. At that time, each tea tree can produce about 8kg-15kg of camellia oleifera fruits. After processing and drying, each tea oil tree can produce about 2kg-4kg of camellia oleifera seeds. When the planting density of tea oil trees is 90 plants per mu, the annual output of camellia oil trees per mu is about 150kg-200kg of camellia seeds. When the oil yield rate of tea oil trees is 23%, the annual output of camellia oil trees per mu is 30kg-30kg of camellia oil. About 50kg.

2. Camellia oleifera planting method

1. Select improved seeds

When planting Camellia oleifera, you need to select good quality seedlings. Pay attention to the environment of the planting site, the flowering cycle of the Camellia oleifera, and its specific characteristics. The environment of the planting site mainly depends on the climate and soil conditions. The flowering cycle of the Camellia oleifera tree depends on whether it is the same. The specific characteristics depend on the size of the fruit and the texture of the peel. Thickness, oil yield and resistance. Fruits should be large and strong, with thin skin, high oil yield and high resistance.

2. Land selection and preparation

The Camellia oleifera planting site should choose a plot with acidic and fertile red or sandy soil. Camellia oleifera in the early growth stage It likes shade, but Camellia oleifera in the later stages of growth cannot do without enough light. The planting site should be selected on a semi-sunny slope or a sunny slope. Land preparation is divided into flat land and cultivated land. All flat land must be plowed, while sloped land does not need to be plowed. Only the plots that need to be planted can be plowed.

3. Reasonable planting

Usually Camellia oleifera is planted in February or October every year, and the planting density is generally about 100 trees per mu. The distance between plants is about 2 meters, and the spacing between rows is about 3 meters. The main sowing methods include seedling cutting and grafting.

4. Scientific fertilization

There are three main stages of fertilization, namely the seedling stage, the three-year fruiting stage and the period of more years. During the seedling stage of Camellia oleifera, nitrogen fertilizer is mainly applied. Nitrogen fertilizer can make Camellia oleifera grow better. Apply fertilizer three times during the three-year fruiting period, namely in spring, flowering period and fruiting period. Apply growing fertilizer in spring, flower-stimulating fertilizer during flowering period, and fruit-strengthening fertilizer during fruiting period. Apply maintenance fertilizer when the growth period is long. The specific time for fertilization is after the camellia oleifera is harvested.

5. Field management

The specific work content of field management mainly includes cultivating and weeding, pest control, branch and leaf pruning and garden cleaning. The frequency of cultivating and weeding is three times a year. Cultivating and weeding can improve the resistance of Camellia oleifera. Pest control is mainly divided into prevention and treatment. When preventing, spray an appropriate amount of Bordeaux mixture or carbendazim, and when treating, spray an appropriate amount of trichlorfon solution. When pruning branches and leaves, vigorously growing branches and leaves should be properly removed, and all weak branches, dead branches, and diseased branches at the bottom should be removed. The time for garden cleaning is after the camellia oleifera is harvested. All debris and dead branches left in the field should be removed, and lime should be used to disinfect the camellia oleifera garden.
