药物处理水稻大苗不带土抛秧采用脱根剂(2甲4氯)、矮化剂(多效唑)、促根剂(萘乙酸)等化学药物处理,取代纸筒、塑料软盘等专用设备,且突破了同类研究根盘带土抛植的习惯做法,提高了水稻抛秧技术的实用性。研究表明,该项技术具有立苗快、植伤轻、积累多、分蘖迅速、群体协调、产量提高等生产特点,是抛秧方式与农艺措施有机结合,调动水稻内在生长潜力的完整技术组合,在水稻大苗栽插地区有着广泛的应用价值。 Drug treatment of rice seedlings without soil throwing seedlings with rooting agent (2 A 4 chlorine), dwarfing agent (paclobutrazol), rooting agent (naphthalene acetic acid) and other chemical treatment, instead of paper drums, plastic floppy disks and other special equipment, and Break through the same kind of study of the root pan with soil throwing habits, improve the practicality of rice throwing technology. The research shows that this technology has the characteristics of fast seedling emergence, light planting, more accumulation, rapid tillering, population coordination and yield increase. It is a complete technical combination of throwing seedlings and agronomic measures to mobilize the inherent growth potential of rice, In the rice planting area has a wide range of applications.
