摘要
1986~1987年在晋东南对大面积生产用种进行了引种比较和若干生理指标的测定,发现晋谷14号无论在引种比较和肥试结果中产量都表现较高,其增产原因主要是晋谷14号具有生育期较长、干物质积累多,对氮素利用率高,根系活力强,后期光合势大等生理特点。无论在瘠薄地上,还是高肥条件下都有较大的增产潜力。从而为肯定晋谷14号作为主干谷种提供了理论依据。
In the southeast Region of Shanxi Province from 1986 to 1987, the introduction of varieties was given a comparison and certain physiological indices were tested with the varieties used in large area under crops. The Jingu Millet No. 14 turned out to have the higher yields in either the introduction of varieties comparison or the fertilizer test. The main reason of high yields is that the Jingu millet No. 14 is provided with such physiological charaters as longer growing period, more accumulation of dry matter, higer N ptake rate, stronger vitality of root system and maximum photosynthetic efficiency in late phase of plant growth. The Jingu Millet No. 14 has great capacity of increasing output, whether it is planted on the barren land or the high fertility soil. The facts, therefore, provide a theoretical basis for determining the Jingu Millet No. 14 as major popularization variety of millet in Shanxi province.
