日本片山制作所研制了一种流体播种机。它可将发芽的种子放入高吸水性、高分子凝胶体——FS内进行播种,既能作到不伤种子,又可均匀地播种,还可节省间苗时间,加快作物生长,使收获期提前。可播发芽长度达5～10毫米的种子。高吸水性、高分子凝胶体——FS是由住友化学工业公司专为流体播种研究的高吸水性、高分子化合物,可吸收并保持相当于自重几百倍的水分,吸水后 Japan Katayama Institute developed a fluid seeder. It can germinate seeds into high water absorption, polymer gel body - FS for sowing, not only do not hurt the seeds, but also sowing evenly, but also save seedling time, speed up crop growth, so that harvest Advance in time. Can sow bud length of 5 to 10 mm of seeds. Superabsorbent Polymer Gel - FS is a superabsorbent, polymer compound designed for fluid seeding research by Sumitomo Chemical Industries, Inc. It absorbs and retains moisture equivalent to hundreds of times its own weight. After absorbing water
