Causes of crack stem stems occur in the harvest period, the reasons are: First, related to water and fertilizer, uneven supply of water and fertilizer, sudden drought, especially when the fleshy stem mature, the skin has been lignified, at this time a lot of water, Sudden enlargement of the fleshy stem, the epidermis can not be enlarged and split; the second is uneven heat and cold; and third, in the absence of boron, the content of vitamin C in lettuce is reduced, and plant resistance to stress and disease resistance is reduced.
Preventive measures First, we must strengthen fertilizer and water management. During the meat enlargement period, the water and fertilizer are increased, the ground is slightly dry, the watering is even, the amount of water must be moderate, and flooding should be strictly prevented. When the ground energy enters, shallow loose soil is broken, combined with watering, and then top dressing 1 or 2 times, spraying poly-boron 1500 times for 1 time to prevent stem cracks from appearing. Second, timely harvest. When the top of the main stem of the lettuce stem is flat with the tip of the tallest leaf, it is suitable for harvesting. At this time, the fleshy stem has been fully expanded, the quality is crisp, and the cracked stem is not easy to appear.
