Canh tác lúa đóng một vai trò quan trọng trong nền văn hóa và chế độ ăn của người dân Việt Nam và nó cũng cung cấp khả năng để giảm thiểu biến đổi khí hậu. Trang trại trên quản lý nước của ruộng lúa là một trong những yếu tố chính ảnh hưởng đến phát thải khí mê tan từ lúa. Bài viết trình bày các kết quả thử nghiệm về ảnh hưởng của nước chế độ trong lĩnh vực gạo về phát thải khí mê-tan từ lúa trên địa bàn tỉnh Hà Tây 2004-2006 | Vietnam Natip nal Commission On Large Dams INFLUENCE OF ON FARM WATER MANGMENT TO THE METHANE EMISSION IN THE RED RIVER DELTA AREA - VIETNAM Nguyen Van Tinh1 Nguyen Quang Trung2 Nguyen Viet Anh3 Abstract Rice cultivation plays an important role in the culture and diets of people of Vietnam and it also offers possibilities to mitigate climate change. The on-farm water management of rice field is one of main factors affecting methane emission from rice field. The paper presents the experimental results on influence of water regime in rice field on the methane emission from rice paddy in Ha Tay province from 2004 to 2006. Rural paysages in the Red River Delta North Vietnam I. Experimental Method - Experimental site the experimental research has been implemented in Hoai Duc District Ha Tay Province it is 13 km far to the west of Hanoi capital. The experimental measure of methane emission from rice field has been conducted in two different treatments such as continuous irrigation point A and intermittent drainage irrigation point B . These two treatments were used in order to assess the potential for methane reduction on rice paddy and to quantify the potential methane emission reduction in the irrigated rice field through water management on rice field. Each treatment is applied in the specific tank with the three dimensions of 1mx1mx1m. - Soil characteristics the soil of rice field is silly clay loam pH organic substance is total N is P2O5 K2O5 . 1Assoc.
