.Early ripening longans at Ne Chau Longan Cooperative, Hong Nam Commune (Hung Yen City)

Due to mastering the technique for longans to flower and fruit early, from mid-March of the solar calendar, Mr. Trinh Ngoc Tiep's family in Ngoc Dong village, Ngoc Thanh commune (Kim Dong) has harvested longans, and traders are busy coming to the garden to visit and order longans. Mr. Tiep shared: With nearly 5 acres of longans, I adjust the flowering and fruiting time into 3 crops, including: Early, middle, and late time by calculating the time of tree zoning and branching to change the flowering time. Along with that, I has to adjust the care of longans to suit the weather, so the longan has a beautiful appearance, and the quality of the fruit is fragrant and sweet. Currently, early ripening longan is sold as a gift, with the selling price in the garden is 35-40 thousand VND/kg, the retail price is 55-60 thousand VND/kg, the supply is not enough to the demand.

Currently, Hung Yen city has over 1,000 hectares of longans, in which, the area of early ripening longan accounts for about 10%, concentrated in the communes: Hong Nam, Quang Chau, Tan Hung. Gardeners apply the techniques to adjust flowering and fruiting in the season, mainly Huong Chi longan, because this is a variety of longan that is evaluated as "pure", easy to care for.

The longan cooperative in Ne Chau, Hong Nam commune (Hung Yen city) has 30 hectares of longans, the area of early ripening longan is about 1 hectare. This year, the cooperative's output of early ripening longan is estimated to reach at 200 tons. Mr. Bui Xuan Su, Deputy Director of Ne Chau Longan Cooperative, said: Currently, the cooperative is associated with a number of growers in Kim Dong and Phu Cu districts to consume early ripening longans with a selling price of 40,000 - 60,000 VND/kg, depending on the time. Although early ripening longan is of high economic efficiency, it is difficult to expand the area because longan cultivation is highly dependent on the weather; people mainly apply care measures to adjust some traditional longan varieties to flower and fruit in different time, there are no early ripening varieties that are resistant to pests and diseases, adapt to the weather, so the yield of early ripening longans of the cooperative is not guaranteed over the years.

In this year's longan crop, the province has nearly 5 thousand hectares of all kinds of longans; in which the area of early ripening longans accounts for about 7%, concentrated in districts: Kim Dong, Tien Lu, Phu Cu and Hung Yen city. According to the evaluation of gardeners, the time of longan flowering encounters adverse weather when the drizzle lasted for many days, the air humidity is high, so the fruiting rate is low. At this time, households producing longans are actively monitoring the changes of weather and pests and diseases on longan trees to actively use preventive medicine. To affirm the brand and improve the production value of longans, the professional industry recommends that people actively apply science and technology to longan cultivation, expand the area of VietGAP longan; cooperate to establish longan cooperatives and cooperative groups to ensure area, unify production processes in order to form safe longan production areas, and expand export-oriented consumption markets. Currently, early ripening longan in the province is easy to consume, the price is high, gardeners need to actively take care of it, ensure the isolation period before harvesting and only harvest when the longan ensures the quality of the fruit.
