近年来,引黄灌区的胡麻播种面积有所下降,糖油争地的矛盾日益突出,为了解决这一问题,我们于1986～1987年进行了胡麻套种甜菜试验,取得了较好的效益。一、胡麻套种甜菜的优点 1.充分利用光热和土地资源。胡麻具有前期生长迅速的特点,可较多地利用前期光能。胡麻7月份收获后,甜菜继续生长到10月底,可充分利用后期光、温。套种与单种相比,甜菜亩产不减,还能多收100公斤胡麻籽。
In recent years, the sown area of flax in Yellow River Irrigation Area has declined, and the conflict between sugar and oil has become increasingly prominent. In order to solve this problem, we conducted the beet intercropping beet experiment from 1986 to 1987 and achieved good benefits. First, flax beet interplanting advantages 1. Make full use of light and heat and land resources. Flax with rapid growth of the early characteristics, can make more use of pre-light energy. Flax harvested in July, beet continue to grow until the end of October, can make full use of late light and warm. Compared with a single species intercropping, beet per mu yield diminished, but also take over 100 kg flaxseed.
