Many vegetable farmers have such a misunderstanding when planting celery, that is, celery is not easy to water, because it is easy to cause the soil temperature to fall, thus affecting the growth of celery. However, lack of water can easily lead to the hollowness of celery.
How does celery prevent hollow disease? Linyi Fertilizer Network Copyright
As long as the watering is suitable, it will not affect the normal growth of celery. Generally, watering once every 15 days, the amount of water should not be too large, and the water can be slid. Especially in the period of strong growth, we must ensure sufficient water supply, about 15 days before harvest, watering should be sufficient. Linyi Fertilizer Network Copyright
Control the appropriate temperature celery is a cold-tolerant vegetable, requires cold and humid environment conditions, cultivate celery in the greenhouse, the temperature during the day is preferably 15 ~ 23 ° C, the highest should not exceed 25 ° C. At night, it should be kept at about 10 °C to reduce nutrient consumption and avoid hollowness. However, the minimum temperature should not be lower than 5 °C, otherwise it is prone to freezing damage and convulsions. Linyi Fertilizer Network Copyright
Fertilizer management is based on the application of the base fertilizer. The long-term topdressing is mainly based on quick-acting nitrogen fertilizer. Combined with the application of potassium fertilizer, the application rate is 20-25 kg per time, and it is chased once every 15 days. Foliar spray application with 0.3% to 0.5% borax solution has obvious effects on preventing the occurrence of hollow disease. Linyi Fertilizer Network Copyright
Harvesting the greenhouse in the timely harvest can not be harvested too late, the harvest period is too late, often cause the senescence of the petiole, the leaf photosynthesis ability declines, the ability of the roots to absorb nutrients will also weaken, the nutrient deficiency will also make the petiole thin wall The cells rupture, causing a hollow phenomenon.

Smart Film Raw Materials
Building use safe glass, can resist the hurricane of 100 kilometers per hour with gravel, special safety glass can resist the bullet shoot, prevent the thief home invasion and shielding high-energy rays (e.g., x-rays), to prevent the spread of fire, and other functions, the main body of glass structure of modern architecture is of special significance, Common safety glass tempered glass, laminated glass, bulletproof glass, film glass, etc., film glass as a new technology, has been included in the national "eleventh five-year" promotion project.
Due to the adoption of the manufacturing process of Switchable Laminated Glass, the safety of intelligent electronically controlled dimming glass is improved. Privacy Dimming Glass has good sound insulation effect. Generally, 5+5 dimmable glass can block noise greater than 35dB.
The dimming glass is made of original toughened glass, which has strong impact resistance and is not easy to break. Electrochromic PDLC Smart Glass made of electrochromic materials not only do not require a backlight, but also save energy as long as the displayed content does not change after displaying a static image.
