According to the Xiaonong.com, the celery is not only delicious, but also has high nutritional value and medicinal value. In addition to rich in various vitamins and minerals, it also has the effects of lowering blood pressure, lowering blood fat, reducing swelling and diuresis. Such healthy vegetables are of course frequent customers and hot-selling products in the vegetable market. They are also the dishes that vegetable growers choose to grow. In order to eat healthy celery all year round, Huinong.com has specially prepared the cultivation techniques of celery. . Planters have a quick look!
The greenhouse celery is generally implemented in summer breeding, autumn planting, winter insulation, New Year's Day, harvest before and after the Spring Festival, celery is like a cool and humid climate, not resistant to high temperatures, the main technical points when planting:
1. Breeding of breeds
For cultivation of celery in greenhouse, it is advisable to use solid celery varieties that are cold-tolerant, rich in flavor, high in yield and good in resistance. At present, varieties suitable for planting in China such as American celery, Dutch celery, Ventura celery, Shuanggang celery, Tianjin solid Celery, California celery and so on. Green celery cultivation technology has long known
2, nursery
The greenhouse cultivation of celery is in the summer, facing the climatic conditions of strong light, high temperature and rainy, so the seedbed is prepared to have the conditions of shading and rain protection.
Before sowing (the seeds are first soaked in 15-20 °C water for 24h, then washed with water for 3-4 times, mixed with fine sand to germination in the environment of 15-18 °C, remember to turn and water every day, keep it moist, about a week It can be germinated. First, the seedbed is poured into the sole water, and then the germinated seeds are evenly spread.
Before seeding, the soil of the seedbed should be kept moist. Before the emergence, the straw should be covered with straw or erected on the surface to prevent direct sunlight and reduce the moisturizing effect. Note that the temperature of the celery seed bed should not be too low throughout the growth period, and the light intensity should not be too weak, otherwise it is easy to twitch in advance to reduce the yield and quality.
3, colonization
Before planting, it is necessary to apply the base fertilizer to the ground. The application of the base fertilizer is mainly organic fertilizer, which can be combined with the application of a small amount of chemical fertilizer, especially phosphorus and potassium fertilizer. Before the seedlings, it is necessary to pour the seedbed into the water so that the seedlings can be uprooted. When planting, pay attention to the tiller planting. The row spacing is 15-20cm, the plant spacing is 10cm, the planting is single planted, the depth is suitable, and the shallow root is not exposed, and the depth is not Degree, planting water immediately after planting.
4, management
The celery seedlings just after planting are in the slow seedling stage, need to be ventilated, maintain proper temperature and humidity, and spraying foliar fertilizer is conducive to promoting the production of new roots.
During seedling growth, the daytime temperature is suitably controlled at 15-25 °C, and the nighttime temperature is suitably controlled at about 10 °C. When the room temperature exceeds 25 °C, the air is required to adjust the temperature. In the late growth stage of celery, the temperature can be appropriately increased. During the daytime, the temperature is controlled at 20-25 °C. As the outdoor temperature decreases, the temperature of the greenhouse at night will also decrease. If it is lower than 10 °C, it is necessary to strengthen the insulation to prevent freezing damage.
After planting for survival, it takes 1-2 weeks for seedlings to be planted. After that, it is necessary to pay attention to keeping the ridge surface dry and wet, laying a good foundation for rapid growth in the middle and late stages. When the celery seedling grows to 6-7 leaves, it begins to enter a prosperous growth period. This is the period of product organ formation and the peak of nutrient absorption. It is necessary to strengthen water and fertilizer management. Under normal circumstances, water is poured every 5-7d, and the fertilizer is chased once between the two waters, that is, two waters are chased by one fertilizer. Each time, 20mL of diammonium or 15kg of urea is chased per acre, and the plants are sprayed without water droplets, and then watered. It can also be combined with irrigation. As the temperature drops and the temperature in the greenhouse decreases, the watering interval is appropriately extended, and water is poured from 10-7 days to 10-15 days. Watering should be carried out in the morning. After watering, it should be strengthened to prevent the humidity from being too large, causing the celery to grow and be sick. The most suitable air humidity for celery is 80% and the soil moisture is 80-90%.
The above-mentioned technical points of planting celery in the small sheds compiled by Huinong. The growers have to learn quickly, and they know that celery is not good enough!
