The application of high technology to agriculture has created an important breakthrough. Besides clean products, poly house farming has raised people's incomes and contributed to effective and sustainable new-style rural building.
The poly house was built in combination with an automatic monitoring, watering, and fertilizing system to save water and increase the efficiency of fertilizer use compared to traditional farming
Hi-tech agriculture has become a familiar concept to people in Pham Tran commune, Gia Loc district. Poly houses springing up one after another have not only increased people's incomes but also contributed to changing rural appearance.
This is also the locality having the largest hi-tech agricultural production area in the province with more than 72,500 m2 of poly houses.
Taking us to his poly houses in which muskmelons were about to be harvested, Tran Van Quang in Nam Cau hamlet said: "Muskmelon is now the most effective plant."
"Each muskmelon crop lasts about 2.5 months, and with a stable selling price of 30,000 VND/kg at present, we will make a profit of more than 20 million VND/sao (360 m2).
"With 7,200 m2 of poly houses for two muskmelon and one cucumber crops each year, I expect to make over 1 billion VND of profit this year, many times higher than open-air farming."
Quang's poly houses are among a few ones in Pham Tran commune. Soil remains unchanged, but modifications in cultivation have brought many breakthroughs to the local agriculture so that soil can "release gold".
Besides clean agricultural products, this model has also created jobs for many local laborers with per capita income of 8 – 9 million VND/month.
Flower and ornamental growing is also one of effective directions of poly house farming.
Knowing the advantages of poly house farming, Tran Van Du in Phu Lien hamlet, Hong Phong commune, Nam Sach district, has built four poly houses covering a total area of nearly 1,000 m2 to grow off-season chrysanthemums and gerberas for higher economic value.
On New Year occasions, he sells each cluster of gerberas for 100,000 VND, twice as high as open-air farming.
With more than 1,500 m2 of poly houses, it is expected that this crop, Pham Van Quyen (left) in Co Bi commune, Binh Giang district, will make a profit of over 100 million VND, much higher than open-air farming
According to the Department of Agriculture and Rural Development, in 2021, the value of cultivation in net and poly houses in the province reached 1 – 3 billion VND/ha/year, and profit averaged 550 million VND/ha/year.
The biggest advantage of poly house farming is slight dependence on the weather. Compared to open-air farming, the amount of plant protection products used for poly house cultivation is reduced by about 70%, and most of the products are rarely harmful to the environment.
The poly house model enables 3 – 4 crops to be produced a year with fewer investment and labor costs but many times higher productivity compared to traditional farming methods.
Products are safely created, meet strict standards of the market, and qualify for export.
With higher production value, people's lives in the region have improved.
Due to awareness about the advantages, the area of poly houses in the province has constantly increased in recent years.
To encourage the development of hi-tech agriculture, the provincial authorities support poly house construction with 100,000 VND/m2 in the 2021 – 2025 period.
By the end of 2021, there were more than 28 poly and net houses in the province, concentrated in Gia Loc, Nam Sach, Cam Giang, Thanh Mien, and Thanh Ha districts and Hai Duong city.
The provincial authorities have planned to assist the construction of 20,000 m2 of poly houses under the project "Developing hi-tech concentrated commodity and organic agriculture in the 2021 – 2025 period with orientation to 2030" in 2022.
