National china
, olive oil began to grow on a large scale in China, the current national planting area of about 1.2 million mu, but low-yielding, inefficient state needs to be improved.
the development of olive oil in Qingchuan County, Guangyuan City, Sichuan Province, or can be regarded as a typical benefit to science and technology. Behind this is the efforts of a research team from the China Forestry Research Institute.
from the beginning of the
since 2000, Aokawa oil olive cultivation area has reached 91,000 mu. In 2018, qingchuan oil olive fresh fruit production reached 3800 tons, fresh fruit direct income reached 38 million yuan, farmers per capita income increased by 3198 yuan. However, Qingchuan oil olives have also walked a low-tech content, poor production efficiency of the road.
" before, Qingchuan olive varieties are very messy, farmers planted for four or five years also can not see the yield, fruit knots sparsely pulled, 1 mu can only pick 10 pounds of fresh fruit. Long Wei, an assistant researcher at the Institute of Subtropical Forestry of the Chinese Academy of Forestry, told China Science Daily.
olive plantations, because of the chaotic cultivation system, the proportion of cultivation area of suitable good species is low and the yield is low. At the same time, most olive groves due to lack of management, tree development age, tree decline, forest difference, group advantage can not be played.
Starting from 2013, Long Wei, as the project leader of "Oil Olive High Exchange Technology Research and Promotion of Productive Cultivation Technology", went to Qingchuan to support the sustainable development of oil olive industry by carrying out research on oil olive high-replacement technology, with a view to screening suitable birch grafting varieties and grafting methods to provide efficient grafting supporting technology;
first of all is high-replacement excellence. How different varieties of birch, spike, grafting method and time affect the graft survival rate require scientific research.
the study of the growth after grafting of various varieties, the researchers made it clear that the growth of "Leixing" "Zhongshan 24" and other high-growth varieties using "City Solid 32" as birch is better than "Foo". Branching is the best method of grafting, with an average survival rate of 97.88 per cent. "The survival rate and growth of birch butt spikes have obvious effects, and there are significant differences in spike length and crown length after grafting between varieties." Long Wei said.The
project also carried out research on seedling technology, analyzed from the ratio of light substations and the growth capacity between varieties, formed a more mature seedling technology system, screened out the two best light substation ratios, and mastered the differences in survival rate, root system and seedling height between varieties.
industry extends the benefits of
."Another reason for the impact on olive production efficiency is that management is not in place." Long Wei explained that olive oil, as an exotic tree species, has higher requirements for climate, soil and moisture. As far as water is concerned, the Mediterranean region is winter rain and our country is summer rain, which will have different effects on olive blossoming.
project to carry out research on the technique of abundant cultivation, in accordance with the principle of suitable trees, in accordance with the published "oil olives rich cultivation technical regulations", strengthen the soil, fertilizer, water, pruning and pest control management of oil olives, requiring the control of sperm control. In the construction of demonstration forest, the production management technology such as integrated tree control, formula fertilization and forest breeding is adopted to make it a demonstration base for the comprehensive application of new varieties and new technologies.
Through the guidance of scientific researchers, the output of high-replacement excellent demonstration forest increased year by year, in the 5th to 7th years will be higher than the existing forest (5 kg of oil per mu) increased by 3 to 10 times, in the fruit-rich period of mu oil production of more than 40 kg. According to the current market crude oil 50 yuan / kg calculation, 30 acres of demonstration forest olive oil sales value alone can reach 360,000 yuan.
project uses a combination of demonstration and training to promote radiation to the surrounding areas. "Focus on cultivating large growers and technical backbones, so that they can master the rich cultivation technology, high-replacement excellent grafting technology and high-efficiency soil and water-saving cultivation technology." Long Wei introduced, "We also hope that through technology-driven, so that farmers set up confidence in development." "
, the project screened out olive varieties with typical Qingchuan characteristics, with strong development value." The olive oil produced by the 'peeling' variety has a significant difference from the volatile substances in other producing areas, and the volatile substances of 'E-plant 8' and 'bean fruit' are also different from the composition of the same varieties in other main producing areas. Long Wei said.
if you want to drink olive tea, Aokawa has a large area of olive oil pruning produced leaves. "Ezhi 8" and "Corati" have a high total flavonoid content, can be used as a raw material for the development of olive tea.
to improve the overall economic benefits, the researchers also fermented the pulp content after the oil olive fruit was pressed, and then carried out back-to-the-field tests, which showed that it could significantly improve soil fertility.
addition to Sichuan, yalin researchers also in Zhejiang and other places to carry out oil olive industry research and technical guidance. "China's olive oil is in a period of rapid development, but industrial promotion can not be blind, the need for varieties and cultivation methods have a scientific understanding, research and guidance."
