以承豆6号为试验材料,设置不同地点、施肥水平与种植密度的处理,研究不同处理对大豆产量及产量构成和品质的影响。结果表明,张家口蔚县、秦皇岛抚宁、承德平泉地区适宜的施肥水平尿素、二胺、氯化钾达到149.6 kg/hm2、180 kg/hm2、149.6 kg/hm2,适宜的种植密度为19.5万株/hm2时产量最高。比较不同试验点的基本地力和气候条件,承德平泉地区与其他两地比较具有较高的碱解氮和速效钾,即使在速效磷和有机质含量偏低的情况下,仍然是承豆6号高产的适宜试验区,其脂肪含量最高,蛋白质含量最低。筛选了不同试验区大豆的适宜施肥水平和种植密度,通过对产量及产量构成和品质的显著性分析,探索出河北省北部山区大豆适宜的丰产高效栽培技术。
Taking Cheng Dou 6 as test material, the treatments of different sites, fertilization levels and planting densities were set up to study the effects of different treatments on soybean yield, yield components and quality. The results showed that suitable fertilization levels of urea, diamine and potassium chloride in Yuxian County, Funing, Qinhuangdao, Pingquan and Chengde were 149.6 kg / hm2, 180 kg / hm2 and 149.6 kg / hm2, respectively. The suitable planting density was 195,000 / hm2 when the highest yield. Comparing the basic geotechnical and climatic conditions at different test sites, Chengde Pingquan had higher alkali-hydrolyzable nitrogen and available potassium than the other two places, even though the contents of available phosphorus and organic matter were low, the yield of Chengdao 6 was still high Suitable test area, the highest fat content, the lowest protein content. The appropriate fertilization level and planting density of soybean in different experimental areas were screened. Based on the significant analysis of yield and yield components and quality, the suitable high yield and high efficient cultivation techniques for soybean in the northern mountainous area of Hebei Province were explored.
