通过对1984～1988年江苏省杂交粳稻区域试验中中粳组合六优1号和六优3-2的产量数据的分析,六优1号属于在中等或中等偏上肥力水平下表现高产稳产,在高把水平下抗倒性弱的组合类型,适宜于我省沿江两岸平原和丘陵地区中等偏上肥力水平的田块种植;六优3-2属于稳产性中等、在较高或高肥水平下产量表现突出的高产组合类型,适宜于我省长江中西部两岸平原和丘陵地区较高肥力水平的田块种植。这为大面积推广应用这两个组合提供了科学依据。
Through the analysis of the yield data of middle-season japonica hybrid rice combinations Liyou 1 and Liuyou 3-2 in the regional experiment of hybrid japonica rice from 1984 to 1988 in Henan Province, Liuyou 1 belongs to the field of high-yielding and stable yield under moderate or moderate upper fertility levels, In the high level of resistance to the combination of the weak type, suitable for our province along the plains and hilly areas on the mid-level upper fertility field plots; Liuyou 3-2 belong to the stable yield of medium, at higher or high fertilizer levels High yield under the outstanding performance of the following types of combinations, suitable for our province in the central and western plains and hilly areas of higher fertility field plots. This provides a scientific basis for large-scale popularization and application of these two combinations.
