What to Do About Hollow Lettuce? Detailed Explanation of Causes and Prevention Measures
Celtuce is a relatively popular vegetable with a crisp texture and good flavor, deeply loved by people, but farmers have found hollow celtuce occurring during production, bringing relatively large economic losses. So what causes hollow celtuce? Let's take a look together with the editor.
1. Related to variety
Different varieties of celtuce have different resistance. Varieties with higher resistance are less prone to hollowing and stem cracking, but the less resistant European varieties are extremely prone to hollowing.
Prevention measures: Before planting, select celtuce varieties with strong resistance and low susceptibility to hollowing according to local conditions, so as to fundamentally prevent hollow lettuce.
2. Improper fertilizer and water management
During the growth period of lettuce, if fertilizer and water management is improper and the supply of fertilizer and water is uneven, the stems of lettuce are extremely prone to cracking, and the hollowing phenomenon is relatively severe. Especially at the mature stage of lettuce, the outer skin gradually lignifies. If watering is excessive at this time, the fleshy stem of celtuce will absorb water and expand, but the lignified outer skin cannot expand accordingly, and at this time hollowing and cracking will occur. In addition, if boron is lacking during the growth period of lettuce, the vitamin C content of lettuce will decrease, and the disease resistance and stress resistance of the plant will both decrease, thereby causing hollowing.
Prevention and control measures: Strengthen fertilizer and water management during the growth period. When the stem begins to expand, apply fertilizer together with watering. After watering, the stem expands faster and the demand for fertilizer and water is large. At this time, pay attention to the amount of watering; flood irrigation is not suitable. After watering, cultivate in time to increase soil permeability and avoid soil compaction. During the fleshy stem expansion period, it is recommended to spray boron fertilizer 1-2 times, which can very well prevent lettuce stem cracking and hollowing.
3. Too late harvesting
After celtuce matures, it should be harvested at the appropriate time. If harvesting is too late, the fleshy stem of celtuce is extremely prone to hollowing, seriously affecting its marketability and edible value.
Prevention measures: Therefore, after lettuce matures, harvest and bring it to market in time, so as to avoid unnecessary economic losses caused by too late harvesting.
