The Latest Field Management Techniques and Methods Tutorial for Celtuce

Celtuce is one of the most common vegetables in our daily lives. Both its stems and leaves are edible, each with its own distinctive flavor. Celtuce has strong adaptability and is widely grown in China. So how should it be managed during cultivation? Let's take a detailed look together.

1. Fertilization

During the cultivation of celtuce, the demand for fertilizer is relatively high. In order to ensure its normal growth and obtain a higher yield, fertilization work must be taken seriously. Throughout the entire growth period, topdressing should be carried out three times. The first time is 10 days after transplanting, when mainly some urea or organic fertilizer is applied, generally by irrigation, so as to avoid excessively high concentration affecting the growth of the seedlings. The second fertilization is when celtuce has grown to 25 cm, still mainly with urea, to promote its growth, generally applying 30 jin of urea per mu. The third fertilization is when the fleshy stem expands, mainly with urea, combined with foliar topdressing by spraying 0.3% monopotassium phosphate to prevent stem cracking.

2. Cultivation and Weeding

After that, attention should be paid to weeding work. When we fertilize, we apply a large amount of chemical fertilizer, and it is mainly nitrogen fertilizer based on urea. At this time, besides celtuce growing faster, weeds also grow faster, so weeding must be done frequently to prevent them from competing with celtuce for nutrients. Long-term application of chemical fertilizers will lead to a decrease in the organic matter content of the soil, very easily causing soil compaction, which is unfavorable to the growth of underground roots and stems. Therefore, timely cultivation should be carried out to loosen the soil, increase soil permeability, and promote the growth of underground roots and stems.

3. Irrigation

Water management for celtuce is also extremely important. When the stem begins to expand, it should be watered in time, and a small amount of nitrogen and potassium fertilizer should be applied together with watering to promote rapid stem expansion and increase yield. However, watering should not be too early or too late. Watering too early will cause excessive leaf growth, consuming too many nutrients, which is unfavorable to stem growth. For low-temperature resistance, it is very prone to disease infection, and watering should also not be excessive. If celtuce lacks water, leaf growth will be inhibited. During long-term drought, encountering heavy rain can very easily cause stem cracking, so the soil should be kept moist in the middle and late stages of growth.

4. Pest and Disease Control

Pests and diseases are also one of the reasons harming the quality and yield of celtuce. The main diseases of celtuce include downy mildew and sclerotinia, while the main pest is aphids. Timely removal techniques should be used, removing old leaves and diseased leaves this time to prevent diseases. When disease occurs, spray Bordeaux mixture for control, spraying once every 7-10 days, with excellent results.
