Greenhouse celery management needs four defenses

Anti-hollow. To prevent celery hollow, cultivation should be selected non-sand soil cultivation, the base fertilizer should be more decomposed organic fertilizer, in the growth and development process, according to the celery growing trend timely dressing, found that light leaf color, de-fertilizer, timely fertilizer. Topdressing application of photosynthetic nutrient film fertilizer (photosynthetic fertilizer) to enhance photosynthesis production of nutrients and chlorophyll, high-level environment-friendly plants to increase fertilizer, increase production, increase color, leaf hypertrophy, dry stem strong composite film. Can help plants absorb a lot of light, light energy, light, compatible with conventional fertilizers, nutrients supply plant growth and development to the limit.

Anti petiole cracking. The temperature and humidity in the shed should be maintained, the soil should be ploughed deeper, more organic fertilizer should be applied, the normal growth and development of roots should be promoted, and their ability to resist drought and cold should be enhanced. When celery is planted, borax can be used as a base fertilizer. Once a slight cracking handle is found, the borax solution can be sprayed on the leaves and the stalks of vegetables can be sprayed on a regular basis. The stem stalks can make the stem thick, the leaves thick, the leaves fresh and the plants flourish. , strong natural taste.

Prevent heartburn. When celery appears to be boiled, management should be started to achieve proper temperature and humidity. Acidic soil should be applied with lime and soil acidity, and the pH of the soil should be adjusted to neutral. At the early stage of disease, 0.5% calcium nitrate aqueous solution + Hushu Grand General can be sprayed to prevent the spread of germs.

Anti-bitterness. Many farmers in the production are accustomed to using urea to increase nitrogen fertilizer. This is very wrong. Applying urea to celery causes bitterness when celery is eaten. Applying urea to celery often results in high fiber content and prone to aging. Another is the production of bitterness. Reduce food value. Therefore, attention should be paid to the use of nitrogen fertilizer to increase the taste of celery. And regularly spraying vegetables Zhuang Ti Ling can make plant stem thick, thick leaves, fresh leaves, plants lush, strong natural taste.
