为了探索水稻高产规律,我们在吴县龙桥大队老农教师和省农科所工人、科研人员的指导下,今年用中籼南京11号作高产栽培试验。试验田设在所内703—707号田,面积13.77亩,土壤肥力较好,其中703号田的前茬是蚕豆,其他都是红花草,土壤有机质含量3％左右,含氮量0.15％左右,速效磷105—120ppm,土壤酸碱度中性。实收产量平均每亩1113斤,其中有2亩单产1200斤。
In order to explore the law of high-yield rice, we Longnan Brigade in Wuxian farmers and the Provincial Agricultural Institute workers, researchers under the guidance of this year with high yield indica rice Nanjing 11 for cultivation experiments. The experimental field is located in the No. 703-707 field with an area of 13.77 mu and the soil fertility is good. The former crop of No. 703 field is broad bean and the others are safflower grass. The soil organic matter content is about 3% and the nitrogen content is about 0.15% Phosphorus 105-120ppm, soil pH neutral. The actual yield of 1113 kg per mu, of which 2 acres yield 1200 pounds.
