1 density is too large. Because the plant spacing, the spacing is too small, or the seedlings are not timely and insufficient, the plants are too crowded, the light in the group is weak, and the photosynthetic products are few, resulting in slender stems, reduced hardness and toughness, elevated ear position, and easy to occur in the event of a storm.
