福州地区春大豆基因型,播期对产量的效应

本文分析了基因型的播种期对春大豆产量及其构成因素的效应,结果表明,播期对春大豆产量及饱粒重的效应大于基因型,而对总荚数的效应较小,因此,必须重视春大豆的播种期,尽量使结荚鼓粒期提前在高温干旱到来之前完成,乃是春大豆高产的关键。不同基因型对环境的反应略有不同,因此要根据不同的前作物和春大豆的播种期,选择合适的基因型。

THE EFFECT OF SOYBEAN GENOTYPES AND SOWING TIME ON YIELD IN FUZHOU AREA

Studies on the effect of genotypes and sowing time on yield and its components were under on spring soybean. The results of the experiment show that the effect of sowing time are larger than genotype effect on yield and plump grain weight, and less on the number of total pods per u-nitarea. The key for high yield per unit area of spring soybean in Fujian is that the sowing time can let soybean to be to have well finished pod and full grain befor the arrival of high temperature and drought season arrived. We use different soybean genotype according to different preceding crop because the effect of various genotypes on environment is different.
