- 摘要:
- 为筛选黑龙江省北部高寒区小粒大豆适宜的施肥方式，提高其产量及品质，以3个小粒大豆的稳定品系为试验材料，每个稳定品系设置3个不同的施肥处理：T1（不施肥）、T2（N 13.5 kg?hm-2+P2O5 34.5 kg?hm-2+K2O5 20 kg?hm-2）、T3（N 18 kg?hm-2+P2O5 46 kg?hm-2+K2O5 25 kg?hm-2），在收获期测定小粒大豆的株高、单株荚数、单株粒数、产量、百粒重、蛋白质含量和脂肪含量。结果表明：施肥处理可以增加小粒大豆的产量、蛋白质含量和脂肪含量，提升小粒大豆的品质。不同施肥处理对小粒大豆产量及品质的影响因品种特性而不同，在种植密度为60万株?hm-2时，小粒大豆最优施肥处理为T2。黑X-9在最优施肥处理条件下表现为产量显著增加，黑X-1和黑X-14在最优施肥处理条件下表现为品质显著提升。
- Abstract:
- In order to screen out the suitable fertilization methods for small-seeded soybean in the northern high cold region of Heilongjiang Province and improve its yield and quality,in this paper,three stable lines of small-seeded soybean were selected as experimental materials,and each stable line was set with three different fertilization treatments: T1(no fertilization),T2(N 13.5 kg?hm-2+P2O534.5 kg?hm-2+K2O520 kg?hm-2),and T3(N 18 kg?hm-2+P2O546 kg?hm-2+K2O525 kg?hm-2),the plant height,pod number per plant,seed number per plant,yield,100-seed weight,protein content and fat content of small-seeded soybean were determined at harvest time.The results showed that fertilization could increase the yield,protein content and fat content of soybean,and improve the quality of soybean.The effects of different fertilization treatments on the yield and quality of soybean were different according to the variety characteristics.When the planting density was 600 000 plants?hm-2,the optimal fertilization treatment was T2.The results showed that the yield of Hei X-9 increased significantly under the optimal fertilization treatment,and the quality of Hei X-1 and Hei X-14 increased significantly under the optimal fertilization treatment.
