多点田间试验及盆栽试验结果表明,淮北平原和长江中下游地区的砂姜黑土、黄棕壤及黄潮土,芝麻施硼增产幅度为1.1—33.7％,平均增产13.1％,其中底施硼肥平均增产10.8％,喷施平均增产17.8％ 施硼提高芝麻含油量,降低蛋白质含量;亚油酸显著增加,其它脂肪酸无明显变化。在缺硼的条件下,芝麻植株矮小,下部叶片增厚,倒卷,严重时植株生长受阻,顶端坏死。
The results of multi-field experiments and pot experiments showed that the yield of boron application increased from 1.1 to 33.7% in the areas of Huaibei Plain and the middle and lower reaches of the Yangtze River, increasing by 13.1% The yield was increased by 10.8% and the average yield was increased by 17.8%. The application of boron increased the oil content of sesame seeds and decreased the protein content. The linoleic acid increased significantly while the other fatty acids showed no obvious changes. In the absence of boron conditions, sesame plants dwarf, lower leaves thickening, rewinding, severe plant growth retardation, the top necrosis.
