1974年初冬,我们在浅水层育萍过程中,发现萍田中露田之处,绿萍长势比有水层的好。我们在12月中旬将萍田中的水放掉,实行露田育萍。结果绿萍长的又快又好,在多风低温的冬季仍能以7天翻一番的速度增殖,并夺得了放养50天亩产8,000斤冬萍的高产。1975年 In the early winter of 1974, during the process of Yiping in the shallow water layer, we found that the fields in the Pingtian area were open and that the development of Luping was better than the water layer. We will release the water in Ping Tin in mid-December and implement Yu Tian Yu Ping. As a result, Luping grows faster and better and can still grow at a rate of doubling in 7 days in wintertime with low wind temperatures, and has won the high yield of 8,000 kg of winter ping stockpile for 50 days of stocking. 1975
