Nowadays, Mr. Nguyen Dinh Tri’s family (resident in Nhon Son Township, Ninh Son District, Ninh Thuan) organizes grape harvest to supply Tet Market. Mr. Tri said that this year, the family still has grapes to sell during the rainy season thanks to the use of the greenhouse vine-growing method.
Accordingly, Mr. Tri’s family grows grapes of all kinds on approx. 1ha. In 2021, he was supported by the Nha Ho Institute of Cotton Research and Agricultural Development to move the technical process of grape production to a high-tech membrane house with an area of 2,500 m2.

For this process, Mr. Tri’s family built and designed the vine in the shape of a Y and a letter T. The garden is covered with insect nets and can be opened and closed by a pulley system. Mr. Tri’s family also used a plastic sheet to cover the top to cover the rain and prevent other elements of the weather.
Mr. Nguyen Dinh Tri confessed that the investment capital of membrane houses is about VND 250 million/1,000 m2 and brings very high efficiency. “For the past few years, every rainy season, the grapes have cracked, rotted… the damage has been very great. This year, thanks to the greenhouse system, the trees still have a high yield, beautiful fruit and good fruit quality in the rainy season. In particular, families with grapes harvested for Tet are selling at a high price,” Tri confided, adding that the application of a membrane house allows the family to harvest 2 grapes per year instead of 1 harvest as before.
According to Mr. Tri, thanks to the greenhouse system, the grapes are less affected by pests and diseases. Therefore, his family restricted the use of pesticides. This helps reduce investment costs and produce products that are safe for health and the environment.

In this year’s Tet harvest, 2,500 m2 of grapes in Mr. Tri’s high-tech membrane house harvests 3-4 tons of all kinds of fruits. NH04 – 102 grapes are sold by him at 200,000 – 250,000 VND/kg and NH01-96 grape varieties are sold at 300,000 – 350,000 VND/kg.
dr Mai Van Hao, director of the Nha Ho Institute of Cotton Research and Agricultural Development, said that in the past, the institute has studied the winegrowing process using high technology and has achieved good results. Currently, the institute has transferred production to a number of farmers in Ninh Thuan and Binh Thuan.
“After more than a year of planting, we have found that greenhouse-grown grapes have very good control of pests during the rainy season, produce safe products and minimize the use of pesticides. Most importantly, humans can harvest up to 1.5 tons of grapes per pole,” said Dr. hey
according to dr Hao greenhouse-grown grapes can limit pests and diseases, improving productivity and product quality. The model is effective, hence it has been learned and replicated by wine growers in Ninh Thuan Province such as Nhon Son Municipality (Ninh Son), Phuoc Thuan Municipality (Ninh Phuoc) and Khanh Hoa and Binh Thuan Provinces.

According to the Nha Ho Institute of Cotton Research and Agricultural Development, the results of the model point a new direction as a prerequisite for replication. The bold use of cutting-edge technology by winegrowers in production has helped improve grape quality and increase market competitiveness.
