通州市每年种植中稻3.8万公顷左右,随中稻抛秧面积迅速扩大,研究本地区“287—3”中稻抛秧合理施肥在生产上有重要意义。1995年我们在二甲、纱场乡布点试验,探索不同土壤上“287—3”中稻抛秧氮磷钾化肥的最佳用量。
Thirty-eight thousand hectares of medium-sized rice are planted in Tongzhou every year. With the rapid increase of the area for throwing young rice, it is of great significance to study the rational application of the “287-3” medium-sized rice in thriving rice cultivation in this region. In 1995, we arranged the tests in Xiajia and Shachang townships to explore the best dosage of NPK fertilizer for “287-3” middle-season rice in different soils.
