Can camellia oil be grown in Cambodia, can camellia oil be grown in those provinces of China

Of course, Cambodia has a variety of tea oil that is unique to the region.

The "tea tree" that produces tea oil and the "tea tree" that produces tea are two different plants of the same genus, and although the tea tree can also produce oil, it is generally not used to extract oil.

Tea tree (tea picker).

Scientific name: camellia sinensis (L.).) o. kuntze

Family: Camellia sinensis.

It is a perennial evergreen woody plant. It is generally a shrub, and there are also arbor type tea trees up to 15-30 meters in tropical areas, with a base tree circumference of more than 10 meters, and the age of the tree can reach hundreds to thousands of years. Tea plants are often cultivated by pruning to inhibit longitudinal growth, so the height of the tree is mostly between meters.

The age of the tea tree is generally 50-60 years. The leaves of the tea tree are oval in shape, with serrated edges, five-petaled white flowers between the leaves, and the fruits are oblate and triangular, and the seeds are exposed after the fruits are opened. In spring and autumn, the young leaves of the tea tree can be picked to make tea, the seeds can be pressed for oil, the tea tree material is fine, and its wood can be used for carving.

There are many varieties of the tea plant that are used to produce tea, mainly Assam, India, China, and Cambodia.

1. Hunan hybrid Camellia oleifera research has made great progress, the yield of camellia oil per mu can reach 35 kg, and the growth cycle of Camellia oleifera seedlings cultivated by two-line hybrid method can be shortened to 1-2 years, and the seedling cost is two-thirds lower than that of ordinary grafted seedlings. 2. The planting cost of camellia oil tree per mu for 3 years is about 600 yuan. 3. The yield of Camellia oleifera per mu can reach about 50 kg, and the output value per mu can reach more than 2,000 yuan.

Addendum: As an aside, I'm from Changsha, Hunan, hehe.

Hunan, Guangxi, buried in Jiangxi, Hubei.

All of them are tea oils that are more suitable for planting. Among them, Hunan is a major province of tea oil in China, accounting for 40% of the country's oil production.

The northern boundary of the distribution of camellia oil is on the first line of the Qinling Mountains of the Huaihe River; The southern boundary is roughly near the Tropic of Capricorn, and the eastern boundary is the southeast coast and Taiwan; The western boundary is the Nu River basin in Yunnan and the eastern edge of the Qinghai-Tibet Plateau chain. It is vertically distributed in the eastern region and below 800 meters above sea level, and can reach 2,000 meters above sea level in the western region.

1. The cultivation method is different

Wild camellia oil is pure natural wild and naturally grown, without pesticides, fertilizers and other harmful substances to the body, and the pressing process is also physically pressed, without adding any chemicals.

The planted camellia oil is an artificially cultivated sapling, and the roots of fruit trees need artificial care: chemical fertilizers need to be applied, pesticides need to be sprayed, so such camellia oil has pesticide and fertilizer residues; Preservatives, chemical decolorizers, etc. are also added during the processing process.

2. The height of growth is not the same

The wild Camellia oleifera trees are slightly tall and disorganized, and the artificial cultivation and pruning of the whole plant is slightly shorter, which will be more neat.

3. The life cycle is not the same

The life cycle of wild Camellia oleifera will be shorter, and the life cycle of artificial cultivation will be longer.

Camellia oleifera planting method.

Planting: When planting, the seedlings should be straightened, and the depth of the root system inserted into the soil layer should be moderate.

The soil is then compacted. Cover the oil tea plants with straw to protect them from overgrown weeds in the spring and exposure to the sun in the summer.

Fertilization: Camellia oleifera combined with tending fertilization can be used as base fertilizer with a pile of dry cake or chicken and duck pen manure, apply 5-10 catties, and can also be replaced by compound fertilizer, but pay attention to the amount. Bury some dead branches of legume plants around the Camellia oleifera seedlings as top dressing.

Pruning: Pruning of Camellia oleifera trees can promote flowering and fruiting, and ensure the healthy growth of Camellia oleifera trees, prolonging the fruiting years. The pruning intensity should not be too large, and the main pruning objects are dead branches, diseased branches, long branches, overly dense branches, etc., leaving strong branches.

Pruning is best done before spring shoots germinate, from December to March of the following year, and the pruning should be close to the trunk and the incision should be as smooth as possible. Pruned branches should be burned intensively to reduce the probability of pests and diseases.

Whether there are relevant subsidies for planting Camellia oleifera trees. How can an individual apply for a Camellia oleifera planting subsidy? As we all know, at the beginning of the development of the camellia industry, a huge amount of start-up capital is needed, for which there are support policies in various places.

The subsidy standard is different for each province and city. For example, some large camellia provinces must have policy preferences; Some places where there are no Camellia oleifera trees, Ken.

According to the test calculation, the construction of new varieties and new technologies with high yield Camellia oleifera base needs to invest 1522 yuan per mu (excluding land rental costs), including 460 yuan for land preparation and burrowing, 132 yuan for base fertilizer, 198 yuan for seedling materials, 60 yuan for planting, and 678 yuan for young forest management (1-3 years). In the construction of the high-yield Camellia oleifera base, a certain subsidy will be given, and the rest will be raised by enterprises or farmers. At present, the average yield of fresh tea fruit per mu in the peak fruit period of Camellia oleifera is 200-600kg, and the average yield of fresh fruit per mu of excellent varieties is 1500kg, calculated by last year's fresh fruit yuan kg (dry seed yuan kg), the income of 200kg per mu can reach 392 yuan, the income of 600kg per mu can reach 840 yuan, and the income of 1500kg per mu can reach 2100 yuan.

If deep processing is carried out, there is still a lot of room for appreciation, and the output value is still higher. Dongxiang County, Jiangxi Province ecological garden seedlings provide high-yield and good clones grafted Camellia oleifera seedlings (field bare root seedlings, container bag seedlings, cuttings seedlings, etc.).

seedlings 1 yuan per plant, 110 plants per mu, a total of 2200 yuan; 600 yuan per mu for land preparation, a total of 12,000 yuan; Fertilizers and pesticides are 200 yuan per mu per year, and a total of 20,000 yuan in the first five years; Loosening soil weeding twice a year, about 250 yuan per mu, a total of 25,000 yuan in the first five years; Rent 50 yuan per mu, a total of 5,000 yuan for five years. In the first five years, a total investment of about 60,000 yuan was made. If the land is your own, choose to bear fruit in 3 years, or work to loosen the soil and weed by yourself, the cost will be less, but the yield is not as high as that of 5 years of fruit.

Generally, the yield per mu can reach 50 80 kg of tea oil in about 10 years, and then slowly increase year by year.
