For farmers in Qujing, money does grow on trees, since the local government enticed Joyvio Group to invest in plantations to grow health-giving blueberries. Wang Hao, Yang Feiyue and Li Yingqing report in Qujing, Yunnan.

Xu Huayuan is using pruning shears to trim blueberry bushes on a vast plantation in Yunnan province.

"You can try one of the blueberries that have turned dark blue on the bushes. They are sweet," says the 32-year-old. Blueberries have been acclaimed by experts as a health-giving superfood.

Xu is a contract worker on a blueberry plantation in the Qilin district of Qujing that is owned by Joyvio Group, the strategic investment arm for food and agribusiness of Legend Holdings.

He has been working for a year at the plantation, which covers 73 hectares, caring for its 240,000 blueberry bushes along with seven others.

His work includes keeping a record of the development of each blueberry bush in the area of the farm he is responsible for, monitoring the changes in temperature and water content on a daily basis throughout the year.

"My life is much easier and more stable now than it used to be," says Xu, who used to grow tobacco on his 0.7 hectare of land. "I had to dig into my own pockets to buy pesticide and fertilizer, do all the heavy lifting during the harvest and find buyers," he says.

His family could make up to 30,000 yuan ($4,500; 3,800 euros; ￡3,360) if there was a good harvest, but would lose it all when the weather wreaked havoc.

The city produces some of the best tobacco nationwide, and its output accounts for approximately 9 percent of the total nationwide.

"Tobacco is still a main industry. But we are trying to create other sectors, like organic farming, vacations and sports tourism, to take up a larger proportion, so that the industrial mix is healthier. Blueberries are our new hope," says Dong Baotong, mayor of Qujing.

Qujing is going all out to upgrade its economic development and industry structure, says Dong. Coal production has been halved compared with its peak period, steel capacity has been reduced, obsolete production equipment has been eliminated and the local government is striving to develop modern plateau agriculture.

As part of this initiative, the local government enticed Joyvio Group to develop its blueberry farms in Qujing in October 2014.

"We had experts determine whether the local climatic conditions were suitable for growing blueberries and offered a series of support measures for the company to settle here," says Zhang Zhen, a senior official with the Qilin district government.

The local climate and slightly acidic soil turned out to be ideal for growing blueberries, which ripen and appear in the market four to five months earlier than those from other parts of the country.

The Qilin government has also spent 12 million yuan building roads, greenhouses and refrigerated warehouses, and it provides the company with an annual subsidy of 1 million yuan.

In addition, local government representatives went door to door to introduce local farmers to the benefits of blueberry plantations, encouraging them to give some of their land for blueberries and to work for the company, according to Zhang.

As a result, more than 500 households agreed to lease some of their land to the company.

"Most of the land being leased was mainly used to grow corn and tobacco before," says He Chongyun, an official in the village where Joyvio is located.

The local farmers could make roughly 2,000 yuan in profit per mu (0.07 hectare) of land in the past if they grew tobacco, a few hundred if they planted corn, He says.

But now they get 1,200 yuan for each mu of land they rent out. The 100 local farmers who have become long-term employees of Joyvio can make 30,000 to 40,000 yuan a year, and those who work part time can earn 70 to 100 yuan a day, based on their responsibilities. During harvest season, the Joyvio facility needs more than 400 temporary workers.

"Moreover, the locals can help with the plantation whenever they have time, because their homes are close by," He says.

To date, Joyvio has also invested more than 400 million yuan in its blueberry plantations in Qujing and developed a standard blueberry cultivation demonstration area, a research and development facility, a seedling breeding base, a cold chain center and a recreational fruit-picking garden.

A seamless and transparent traceability system from cultivation to sales has taken shape. So far, the company has established 667 hectares of blueberry plantations in Qujing, which has enabled local farmers to earn 5.8 million yuan from leasing their land to the company and 9 million yuan from working on the plantations.

Qujing's blueberry growing potential has also attracted the attention of the International Blueberry Organization, which co-hosted an international blueberry conference in Qujing in early September to introduce the city to potential investors.

"I've talked to five enterprises specializing in cold chains, financing and agricultural equipment, which can help us develop the industry upstream and downstream," says Cui Xingguo, general manager of Joyvio Qujing Agriculture Co.

Joyvio will continue to work with rural cooperatives and capital funds, introduce new blueberry species, standardize blueberry growth practices and expand blueberry production in the future, Cui says.

The Qilin district alone has its sights set on developing a 2,000-hectare blueberry industry belt over the next five years, with the goal of producing 30,000 tons of quality blueberries and more than 3 billion yuan in output value.

Xu Huayuan is content to look after his blueberry bushes, but he still has 0.4 hectare of land on which his family grows tobacco.

The company has taught him certain blueberry plantation techniques, but there are still things that are difficult for him to understand.

"There's still a lot for me to learn. But hopefully I can learn all it takes to grow blueberries on my own land one day," Xu says.
