Celery is prone to hollow problems, how to prevent it?

Celery belongs to Umbelliferae. There are three kinds of celery: celery, celery and celery. Eating celery, especially celery leaves, is very beneficial to prevent hypertension and arteriosclerosis, and has an auxiliary treatment effect. Water spinach is a common physiological disease in celery planting. After hollow celery, the cellulose increased, the quality deteriorated and the yield decreased, which seriously affected the commercial and economic value of celery and dampened the enthusiasm of farmers for planting. Today we are going to talk about celery valley.

1. Land

Celery generally likes slightly alkaline or slightly acidic soil. Celery is prone to hollowing out in the land with strong salt content, high viscosity or high sandy nature and serious pests and diseases.

2. Insufficient fertilizer

Celery root system is not deep, and its ability to absorb fertilizer is not strong. So pay attention to the fertilization method of celery. Celery, for example, needs phosphate fertilizer in the early stage of growth, which will lead to the phenomenon of hollow stems in the later stage.

3. High temperature and drought

Celery likes cold and humid climate and is a semi-cold-tolerant vegetable. If you encounter high temperature and drought, especially in summer, the temperature difference between day and night is too small, the soil is short of water, and the respiratory consumption is too high, which is easy to cause hollowing out.

4. Temperature and light

Too low temperature, insufficient light or freezing injury will weaken the photosynthesis of leaves, hinder the absorption and operation of nutrients and water by roots, and cause cavities.

5. The harvest is too late

When celery is harvested too late, the root absorption capacity decreases, the cells are broken, the tissue is loose, and the petiole is easy to age and become empty.

6. Scientific seed selection

Seeds should be purchased from the formal sector. It is suggested to choose solid celery with strong disease resistance, strong growth and good quality.

7. Choose the right plot

It is best not to choose sandy loam for planting soil, but to choose sandy loam plots with thick soil layer, rich organic matter, strong water and fertility conservation and convenient irrigation and drainage. The pH value of soil is neutral or slightly acidic.

8. Temperature and humidity control

Celery likes cold and humid environment, and celery is cultivated in greenhouse. The daytime temperature is 15-20℃, and the temperature does not exceed 25℃. Keep it at 10℃ at night to reduce respiratory consumption and avoid empty drum, but it should not be lower than 5℃, otherwise freezing injury and early bolting will easily occur. Proper ventilation at ordinary times to reduce air humidity.

9. Strengthen fertilizer and water management

It is suggested that basal fertilizer should be applied to celery, supplemented by topdressing. Farmhouse manure or decomposed organic fertilizer is generally used as base fertilizer, and chemical fertilizer should be avoided when topdressing, and thin fertilizer can be applied.

10. Pest control

Deal with the diseases and pests in celery in time to ensure that celery has strong photosynthesis.

1 1. Timely harvest

Don't harvest too late. If it is too late, the petiole will age and become hollow.
