Boron is an essential trace element for plant growth and development, playing a critical role in flowering, fruit setting, nutrient transport, and stress resistance in crops. Buckwheat is an important coarse grain crop, and its yield and quality are easily affected by boron nutritional status.
In order to identify the optimal concentration of boron fertilizer to maximize growth and yield of buckwheat, pot experiments and field trials were carried out at different mass concentrations of boron fertilizer solution: 0, 12, 24, 48, and 72 mg/L.
The results showed that 48 mg/L boron fertilizer solution promoted seed germination and seedling growth of Suqiao 1, whereas 24 mg/L boron fertilizer solution had the best effect on seed germination and seedling growth of 1412-69. Moreover, the levels of activity of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) of Suqiao 1 seedlings were highest under the 48 mg/L boron fertilizer treatment, and those in 1412-69 were highest under the 24 mg/L treatment. The highest grain yield and grain quality of Suqiao 1 were found at a boron concentration of 48 mg/L, whereas grain yield and quality of 1412-69 were maximized at a concentration of 24 mg/L.
In summary, boron fertilizer solutions at optimal concentrations can effectively stimulate buckwheat seed germination and seedling growth and thus enhance buckwheat yield.
硼是植物生长发育必需的微量元素，对作物的开花、坐果、养分运输和抗逆性起着关键作用。荞麦是一种重要的粗粮作物，其产量和品质易受硼营养状况的影响。
为了确定能使荞麦生长和产量最大化的最佳硼肥浓度，在不同质量浓度的硼肥溶液（0、12、24、48和72毫克/升）下进行了盆栽试验和田间试验。
结果表明，48毫克/升的硼肥溶液促进了苏乔1号的种子萌发和幼苗生长，而24毫克/升的硼肥溶液对1412 - 69的种子萌发和幼苗生长效果最佳。此外，苏乔1号幼苗的超氧化物歧化酶（SOD）、过氧化氢酶（CAT）和过氧化物酶（POD）活性水平在48毫克/升硼肥处理下最高，1412 - 69在24毫克/升处理下最高。苏乔1号在硼浓度为48毫克/升时籽粒产量和品质最高，而1412 - 69在浓度为24毫克/升时籽粒产量和品质达到最大值。
综上所述，最佳浓度的硼肥溶液能有效刺激荞麦种子萌发和幼苗生长，从而提高荞麦产量。
