本文通过1988～1990年度的研究,明确了三类高产品种产量与其构成因素的关系,比较了三类品种的产量潜力和稳产性能,认为中间型品种具有较多的有利因素.在山东生态条件下,高产品种的产量结构,应在兼容大穗型、多穗型品种的前提下,着重走中间型的路子.
Through the research from 1988 to 1990, this paper clarified the relationship between the yield of three types of high-yielding varieties and their components, and compared the yield potential and stable yield of the three types of varieties, and considered that intermediate-type varieties had more favorable factors. Under the ecological conditions of Shandong The yield structure of high-yielding varieties should focus on the intermediate path under the premise of compatibility with large-spike and multi-spike varieties.
