Excuse me, which variety is better, big fruit safflower oil tea or Cenxi soft branch oil tea?
Camellia oleifera from tengxian, also known as Camellia oleifera from tengxian, has a single fruit weight of 1-3 kg and a single plant of 60-300 kg. It originated from the deep forest in Tianping Town, tengxian, Wuzhou City, Guangxi Province, and has been cultivated and improved for a long time. The existing high-yield Camellia oleifera forest is about 1 1,000 mu, and Wuzhou TV Station and Guangxi TV Station,>. & lt& lt rural intellectuals >>& lt& lt planting and breeding >>. News media such as<& lt Southern Science and Technology News & gt made special reports, which caused a sensational effect and aroused widespread concern in society. It has attracted a large number of merchants from Camellia producing areas including Taiwan Province Province to visit and inspect, and some cities and counties in Guangxi, Guangdong, Hainan, Yunnan, Guizhou, Hunan, Jiangxi, Zhejiang and other provinces have established projects for development. If 1 100 million mu of camellia oleifera can be planted in the vast camellia oleifera producing areas in China, the annual economic benefits will be 654.38+000 billion ~ 300 billion yuan in a few years, and the economic benefits of comprehensive development and deep processing can be doubled. This kind of camellia oleifera has high yield, good oil quality and high benefit. It is the most potential camellia oleifera variety at present. If it is developed and planted vigorously, its social, economic and ecological benefits will be immeasurable. Tengxian Juguo Camellia oleifera has strong adaptability. Camellia oleifera can be planted in all producing areas, and it is resistant to-100℃ cold and 400℃ heat, with few pests and diseases, drought resistance, cold resistance and barren resistance; In recent years, Guangxi has blossomed and borne fruit as usual without rain in autumn and winter. Grafted seedlings bloom in 2-3 years, bear fruit in 4 years and have high yield in 6-7 years. Seedlings bloom later than grafted seedlings 1-2 years. Camellia oleifera is extensively managed, with a yield of 25-35 kg per mu, a moderate yield of more than 40 kg per mu, and a careful management of more than 75 kg per mu, which is more than five times higher than that of ordinary Camellia oleifera. At present, the price of tea oil in the producing area is 40 yuan per kilogram to 50 yuan, which is in short supply. The output value per mu 1000 to 3000 yuan, with considerable economic benefits. The unsaturated fat content of Camellia oleifera is about 90% by the quality supervision and inspection center of grain and oil products of the Ministry of Agriculture. It is rich in 17 kinds of amino acids and trace elements such as zinc and selenium, which are essential to human body, and its quality exceeds that of olive oil, the first oil in the west. Regular consumption of camellia oil can effectively reduce cardiovascular and cerebrovascular diseases, as well as reduce blood fat, blood pressure, anti-aging and prolong life. American authoritative experts ranked China camellia oil ahead of olive oil, and confirmed that camellia oil is the best edible oil in the world at present. Camellia oil is increasingly favored by people in developed countries and middle-and high-income citizens in China. Its development prospect is infinitely broad. Camellia oleifera was designated as the special edible oil for the 2008 Olympic Games. Tengxian Juguo Camellia oleifera is famous for its high yield, high quality and high benefit, and is known as the best Camellia oleifera in the world. Compared with common camellia oleifera, it can break six world records: first, the largest tea fruit: the average single fruit is more than 0.5 kg, and the largest is 1.8 kg; Second, the highest fruit yield: normal plants set 40 ~100 kg; Third, the oil yield is extremely high: the oil yield of dry seeds is 35-40%, and the oil yield of tea seeds is 55-62%; Fourth, there are many camellias: 1000 to 5000 bright camellias; 5. The longest flowering period:165438+/kloc-0 from early October to late March of the following year, *** 140 days; 6. Longest life span: During the growing period 100 to 200 years, old trees over 100 years will blossom and bear fruit as usual, 100 to 250 kilograms.

Camellia oleifera from Cenxi is an excellent variety selected by Guangxi Academy of Forestry after 15 years of seedling propagation and systematic variety comparison test. Mainly distributed in Cenxi, tengxian, Cangwu and other places in Guangxi, it belongs to a peasant variety of common camellia oleifera. At present, this variety has passed the national examination and approval of improved forest varieties. Experts believe that the improved varieties of soft branch Camellia oleifera in Cenxi have high popularization and utilization value.

The shoots of Camellia oleifera in Cenxi have the characteristics of fast growth, early fruiting, high and stable yield and strong adaptability. It blooms and bears fruit 2 ~ 3 years earlier than common camellia varieties, and its yield is 1 ~ 3 times higher. It blooms in 3 ~ 4 years after planting, and enters the rich period in 7 years. In good years, the yield per mu can exceed 60 kg, and the oil content is as high as 5 1.37%. Good oil quality, acid value 1.06~ 1.46, refractive index1.4672; According to the progeny test, all economic characters can be stably inherited. 1973, cenxi soft branch Camellia oleifera was identified as the first fine variety of Camellia oleifera in China by experts from the National Camellia oleifera Cooperation Group. 1978 won the National Science Conference Achievement Award and the Guangxi Science Conference Outstanding Science and Technology Achievement Award.

After being recognized as an excellent variety of Camellia oleifera, Cenxi Soft-branch Camellia oleifera was introduced and cultivated in more than 300 units in Guangxi and even South China 13 provinces (regions) in the mid-1970s. By 198 1, more than 300,000 mu had been planted. The regional experiment showed that the oil-tea tree in Cenxi grew well, grew fast, bore early fruits, had high yield and strong adaptability in all parts of Guangxi. Guangdong, Hunan, Fujian, Jiangxi, Guizhou, Zhejiang, Anhui, etc. 13 southern provinces (regions) have better introduction and cultivation, and also show excellent characteristics of fast growth, early fruiting and high yield.

In recent years, Guangxi has taken advantage of Nanning's unique geographical advantage as the venue of the ASEAN Expo to actively carry out technical cooperation and exchanges with ASEAN countries and advantageous enterprises. At the same time, around the forestry development strategies such as western development and returning farmland to forests, Guangxi has further increased the development and utilization of improved varieties of soft-branch Camellia oleifera in Cenxi, broadening the market space for the development of Camellia oleifera industry.

From 2005 to 2007, Guangxi Academy of Forestry, in the name of the people's government of the autonomous region, was responsible for presenting 42,000 high-quality seedlings and 2,750 kilograms of seeds of Camellia oleifera to Cenxi, Thailand, which could afforest more than 6,000 mu. According to the investigation, the high-quality seedlings of Camellia oleifera in Cenxi grow well in Thailand, and the afforestation preservation rate reaches 96%, and some plants have blossomed in the second year. In recent years, Guangxi Academy of Forestry has provided 50,000 seedlings 1.5 thousand plants and more than 50,000 kilograms of seeds to Thailand, Viet Nam, China, Guangdong, Zhejiang and Fujian provinces, with an afforestation area of 200,000 mu.

The main morphological characteristics of soft-branched Camellia oleifera in Cenxi are large branching angle, large leaves and soft branches, and large crown width. The angle between the main branch and the backbone branch is 60 degrees, and the angle between the branchlets and the main branch is 50 degrees. Because the branch angle of the main branch is large, it extends outward to form a "natural happy-shaped" crown. The density of branches is moderate, the light transmission condition is good, and the lateral branches grow vigorously, which is beneficial to the manufacture and distribution of leaf nutrients, can inhibit the apical advantage, and is more conducive to the growth of flowering and fruiting branches. In general, the angle between the main branch and the backbone branch, and the angle between the twig and the main branch is only 40 ~ 35 degrees. The crown is erect, the branches and leaves are dense, and the light transmittance is poor, which seriously affects the flowering and fruiting of trees.

Long-term planting has proved that more than 70% of the tender shoots of camellia have maintained the excellent branching characteristics of the female parent, showing high heritability and basically maintaining high-yield performance. The soft branches of Camellia oleifera are soft and drooping, which is more productive than the hard branches. This fine trait can also be inherited relatively stably, and its offspring can still reproduce the fine characteristics of early fruiting and high yield.

High and stable yield is a very important economic character in camellia oleifera seed selection, and it must be relatively unified as far as possible. High yield without relative stability is not a real thoroughbred, and vice versa. There are both soft-branch camellia oleifera in Cenxi. If the output of Camellia oleifera does not change more than 30% for three consecutive years, it is a sign of stable production. The experiment proved that the sustainable yield increase of Cenxi Camellia oleifera was 18 years, and the yield increase range was only 4.3%~28.7%, while that of other varieties was 9% ~ 52.6%. In addition, after 7 years of planting, camellia twigs will enter a wet season, which can last for 50 to 60 years. If intensive management can be carried out, it can be extended to 60 to 80 years. However, the common Camellia oleifera did not enter the rich period until 10 ~ 12 years after planting, and the rich period was only 30 ~ 40 years.

According to experts, the soft-branch Camellia oleifera in Cenxi has excellent economic characters, morphological characteristics or physiological characteristics, such as fast growth, early fruiting, high and stable yield, strong adaptability and good oil quality, and it is not only obvious in the contemporary era, but also can be stably inherited by future generations. Therefore, in the case of a small number of excellent families or clones of Camellia oleifera that have passed the examination and approval of national or local forest varieties, it can be popularized and applied in the afforestation of improved seedlings of Camellia oleifera in Cenxi City. At the same time, in order to improve the survival rate of afforestation, prolong the afforestation time, ensure the afforestation quality and accelerate the growth of seedlings, seed container seedling raising and afforestation should be vigorously promoted.

These two varieties are both good and can be planted. Camellia oleifera belongs to cross-pollinated plants, and many camellia oleifera forests are beneficial to pollination.
