The invention relates to a modern agricultural planting technology and in particular to a method for planting spinaches in an artificial light type plant factory. According to the method for planting the spinaches in the artificial light type plant factory, high-quality spinaches are highly efficiently obtained via synergistic effects of synergizing the light quality, light intensity, light period at each growth stage with environmental factors, such as temperature, humidity and fertilizers , based on the growth habits of the spinaches. In the method for planting the spinaches in the artificial light type plant factory, the growth habits of the spinaches are fully utilized, not only are leaf areas, fresh weight and plant height of the spinaches increased, but also the content of protein in the spinaches is increased, so that the spinaches are high in nutritional value, the content of tannin in the spinaches is increased, the astringency of the spinaches during eating is effectively reduced, and the content of nitrate in the spinaches is also reduced; furthermore, influence of seasons on spinach planting is avoided, and the method for planting the spinaches in the artificial light type plant factory is significant to large-scale indoor production of edible spinaches.
