利用1986～1993年河北省水稻区试资料,根据8年区试对照品种冀粳8号的产量,得出该品种在全省范围内的高产潜力和一般亩产。利用本文提出的有关产量实现率、年成指数、高产潜力、一般亩产等估算公式,估算各年份,反映环境对产量影响的两项指标,即产量潜力实现率和年成指数,从而估算参试品种在我省的产量潜力。估算结果表明:该估算方法具有一定的准确性、可行性、科学性。
Based on the data of Hebei area from 1986 to 1993, the high yield potential and general mu yield of this variety in the whole province were obtained according to the yield of the 8-year regional trial variety Jijing 8. Using the proposed production yield, annual average index, high yield potential and general mu production estimated by this paper, we can estimate the annual output and reflect the impact of the environment on the yield of the two indicators, namely the yield potential and the annual index to estimate the parameters Test varieties in our province’s yield potential. The estimation results show that the estimation method has certain accuracy, feasibility and scientificity.
