摘　　要：针对水稻一季产量15 t/hm^2可遇不可求、复制难、重演性差的现状,笔者认为问题的关键在于未培育出具有高产潜力的农田土壤和未对水稻株型调控引起足够的重视。据此,笔者提出"三足鼎立"超高产栽培技术:选用超大穗、强耐肥抗倒、营养生长不易过旺的偏粳型品种,在当地生态条件下产量潜力可达15 t/hm^2;培育水肥气热高水平供应协调,基础产量在10 t/hm^2以上农田;采取以控制营养生长过旺为突破口的超高产株型栽培。并对有关原则性技术进行了讨论。In view of the fact that the rice yield of 15 t/hm^2 in single season is not easy to obtain and has poor repeatability. Comprehensive summary the reflection, the key to the problem lies in not paying enough attention to cultivation farmland soil of high yield and the regulation of rice plant type. Based on this, the author proposed "tripod stands"super high-yield cultivation technology: selecting partial japonica varieties with super large ears, strong fertilizer resistance and lodging resistance, and the vegetative growth is not easy to overgrow, the yield potential of 15 t/hm^2 under local ecological conditions;cultivating farmland with high-level supply coordination of water, fertilizer, gas and heat, and the basic grain yield is above 10 t/hm^2;adopting the"tripod stands"super high yield plant type cultivation which could control the excessive growth of nutrients as a breakthrough. The principled techniques were dis-cussed in this paper.
