在沈阳、铁岭地区,谷子是适期早播好,还是适期晚播好,在生产上一直是个争论问题。为了在这两个地区寻求谷子的适宜播期,我们于1980～1981年,在沈阳农学院院内连续进行了谷子分期播种试验。不仅从形态上进行细致观察,而且采用生长分析法进行了数量分析,揭示不同播期对谷子同化产物的分配过程和产量形成的生理基础的影响,了解谷子生长发育规律及其与内外因素的相互关系。试验结果表明,在沈阳、铁岭地区,谷子适宜播期以4月15日至5月5日为好,4月25日左右播种尤为适宜。
In Shenyang, Tieling, millet is suitable for early sowing good, or good late broadcast good, in the production has been a controversial issue. In order to seek suitable sowing dates for these two areas, we conducted a continuous crop trial of millet staging in Shenyang College of Agriculture from 1980 to 1981. Not only the morphological observation was carried out but also the quantitative analysis was conducted by using the growth analysis method to reveal the influence of different sowing dates on the physiological process of the assimilation product distribution and the yield formation of millet and to understand the law of millet growth and development and its interaction with the internal and external factors relationship. The test results show that in Shenyang, Tieling region, millet suitable sowing April 15 to May 5 is better, about April 25 planting is particularly appropriate.
