我县中稻“691”无论种植面积和总产都居粮食作物首位。但湖田因地势低洼,排水条件差,常年淹水受涝的面积大,单产较低。如1980和1983这两年,因特大涝灾使中稻“691”不同程度减产的面积占60％左右,平均收获面积只占插秧面积的87％,亩产只771斤,淹水严重的田块一般只200—500斤,和正常的1981和1982两年比较,收获面积要减少12.8％,亩产减少81斤,总产减少20.9％。 My county middle rice “691” irrespective of planting area and total output are the first place in food crops. However, due to low lying terrain lake, drainage conditions are poor, perennial flooding by flooding the area, lower yields. For example, in 1980 and 1983, about 60% of middle-grade rice “691” was cut by different degrees due to extra-large floods. The average harvested area only accounted for 87% of the area planted, with a yield of 771 kg per mu and a flooded block Only 200-500 jin. Compared with the normal two years of 1981 and 1982, the harvested area should be reduced by 12.8%, the yield per mu reduced by 81 kg, and the total output decreased by 20.9%.
