大豆是需水较多的作物。近几年来,由于干旱时有发生,影响了大豆产量,使大豆生产效益降低,播种面积出现滑坡。为减轻干旱对大豆产量的影响,1989年起,我们开原市农业技术推广中心进行了大豆大垄双行栽培试验。 试验结果证明,这种栽培形式具有明显的抗旱增产作用。由于这种栽培方式有利于通风透光,有利于光合产物的积累,单株叶片干重比对照多1.18—3.42克,单株叶面积比对照增加
Soybeans are crops that require more water. In recent years, due to the occurrence of drought from time to time, affecting soybean production, reduce soybean production efficiency, sown area landslide. To alleviate the impact of drought on soybean yield, since 1989, we opened the Agricultural Technology Extension Center of soybeans big ridge double row cultivation experiments. The test results show that this form of cultivation has obvious drought-resistant and yield-increasing effects. As this cultivation method is conducive to ventilation and light, is conducive to the accumulation of photosynthetic products, leaf weight per plant more than the control 1.18-3.42 grams, leaf area per plant increased compared with the control
