裕公公社农科所是1976年冬由生产队转建的。建所前的水田,地下水位高、深脚烂泥。种一季中稻时生长尚好。改种绿肥、双季稻后,由于泡水时间长、没有干耕晒垡的机会,虽施肥量逐年增加,土壤理化性状却渐趋恶化,早稻迟发现象严重。因此,1977年他们在制定早稻栽培措施时,围绕“水”字做文章,采取了四条控水措施:①深开水、旱分家沟,戴拦旱地的汇集水。②水田每隔60米开一条窄深沟,沟深2尺以上,低于稀泥层,
Yu Gongsong Agricultural Science Institute was the winter of 1976 by the production team to build. Before the construction of paddy fields, high water table, deep mud. A quarter of rice is still growing well. After re-planting green manures and double cropping paddy, there is no chance of dry-farming drying due to soaking in water for a long time. Although the amount of fertilization increases year by year, the physical and chemical properties of soil are deteriorating. Therefore, in 1977 when they formulated the early rice cultivation measures, they made four articles on water control around the word “water.” ② paddy fields every 60 meters to open a narrow deep trench, ditch deeper than 2 feet, below the slime layer,
