What should be guarded against greenhouse celery management?

Greenhouse celery management should be hollow. Prevent celery from appearing hollow. When planting, choose non-sand soil cultivation. The base fertilizer should be applied with decomposed organic fertilizer. During the growth and development process, the celery should be topdressed according to the growth trend. When the color of the leaves is shallow, when the fertilizer is removed, the fertilizer should be applied in time. Topdressing application of photosynthetic nutrient film fertilizer (light fertilizer), advanced environmentally friendly compound film, can help plants absorb a lot of light fertilizer, light energy, light, nutrients, and supply plant growth and development to the limit.

Greenhouse celery management should prevent cracking of the petiole. The temperature and humidity in the shed should be maintained, the soil should be deeply cultivated, and organic fertilizer should be applied to promote the normal growth and development of the root system and enhance its ability to resist drought and cold. When planting celery, borax can be used as the base fertilizer. Once a slight crack is found, the borax solution can be sprayed with foliar spray, and the vegetable stalk can be sprayed on the celery regularly to make the stems of the plants strong, the leaves are thick, the leaves are fresh and tender, and the plants are planted. Lush, natural taste is strong. Linyi Fertilizer Network Copyright
Greenhouse celery management should be protected against heartburn. The celery has a heartburn, it should be started from the management, so that the temperature and humidity are suitable. For the acidic soil, the lime and the soil acidity should be applied, and the pH of the soil should be adjusted to neutral. In the early stage of the disease, 0.5% calcium nitrate aqueous solution + tree guard general can be used to prevent the spread of pathogens. Linyi Fertilizer Network Copyright
Greenhouse celery management should be protected from bitterness. Many farmers in the production habitually apply urea to increase nitrogen fertilizer. This practice is wrong, because the application of urea in celery often makes it high in fiber content, prone to aging, bitterness and reduced food value. Therefore, in the production should pay attention to the application of nitrogen fertilizer to improve the taste of celery. Linyi Fertilizer Network Copyright
