How much profit is it to plant camellia trees per mu? is there a subsidy for mountain forests to grow camellia trees?

Camellia is a kind of common tree in our country, its fruit can be made into camellia oil, which is very popular with people. Nowadays, there are also a lot of people planting camellia, but before planting, many people want to have a comprehensive understanding of its profits. If you want to know more, let's look down together.

How much is the profit of planting one mu of camellia

Based on the 15 jin fruit yield per plant and the conservative market purchase price of 1 yuan / jin, the fruit yield per mu is about 1650 jin, and the output value per mu is about 1650 yuan. After deducting the annual input of 450 yuan / mu, the gross income per mu is 1200 yuan.

Is there a subsidy for planting camellia trees in mountain forests?

The camellia tree is generally planted as an economic crop and can produce camellia oil. in this case, there should be a subsidy in the policy of returning farmland to forests, but the requirements vary from place to place. For example, the Neijiang government in Sichuan requires that it return farmland to forests to plant bamboo and lemon. If it is included in the land, you can enjoy the policy of returning farmland to forest. You can consult with the local forestry bureau.

How to plant camellia trees

1. Planting density: the planting density is determined according to plot, slope, light intensity and management level. In the flat land with deep and fertile soil layer, the row spacing is 3 × 3 m, 74 plants per mu, 89 plants per mu at the foot of slope and gentle slope, and 2.5 × 2.5 m at the slope above 20 degrees, 108 plants per mu.

2. Land preparation: remove all the weeds and shrubs on the mountain. The size of the pond is 40 × 40 × 30 cm. The area with thin soil layer can be bigger. If possible, each pond can be filled with 1kg of calcium magnesium phosphorus or 5kg of 10kg farm manure mixed with soil as base fertilizer. Unconditionally, the surface fertilizer should be collected from around the pond and filled into the pond, and the backfill should be 20 cm above the ground.

3. Topdressing management: young tree stage (1-5 years): topdressing is mainly nitrogen fertilizer. Each plant needs about 2 taels of urea per year, which is applied 4-5 times, with more and less amount each time. Dig a hole from the four directions of the seedling for application, about 10 cm away from the seedling.

4. Soil management: all the Camellia oleifera forests were dug up in winter, and large stones and malignant weeds were found, and the weeds were spread in the tree ponds. The dug clod should not be knocked fine and let it be weathered naturally. Weeds should be weeded 2 or 3 times a year, and the grass should not be burned, allowing it to rot naturally in the field and increase soil organic matter.

Common diseases and insect pests of camellia and their control

1. Grey spot of camellia. Removal of diseased leaves in the early stage of the disease to reduce the source of infection, including the removal of disease and fallen leaves before overwintering, deep burial or burning. After the new leaves grow, spray 70% mancozeb 600x solution or 70% methyl thiophanate ultra-fine wettable powder 1000 times solution, 1 160200-fold Bordeaux solution, once every 10 days, a total of 4-5 times between June and September.

2. Camellia spot disease. Remove the diseased leaves and spray 75% chlorothalonil 600 times, or 0.15% potassium permanganate solution.

3. Tea yellow moth: when the larvae are clustered, the leaves can be removed. Don't touch the poisonous hair when picking. At the initial stage of larval occurrence, the larvae were sprayed with 1000 times of any insecticide, 2000 times of 80% dichlorvos EC, or 3000 times of 2.5% deltamethrin EC.

4. Tea aphid. Winter combined with pruning, cutting off egg branches or damaged branches to reduce the population base of overwintering insects. Pick the heart or wipe the buds during the growing season to remove the killed and irregular shoots. Reduce the diet of aphids to reduce the number of aphids. In the season of high temperature, fast reproduction and large number of natural enemies, the protection and utilization of natural enemies should not be sprayed or less sprayed as far as possible, or selective pesticides with low lethality to natural enemies should be sprayed to avoid killing natural enemies. Or focus on spraying aphids as seriously harmful trees to protect natural enemies. On trees with a small number of natural enemies, aphids can be artificially diverted and released, such as ladybugs and lacewings.

Whether camellia is subsidized or not mainly depends on the policy of each place, so it should be consulted locally. As long as the camellia tree is planted well, the profit is still considerable. When planting, we must pay attention to the density, but also need timely topdressing and control of diseases and insect pests.
