Preservation technique of celery
The celery petiole is wide, thick and flat, with less fiber, more solid, light fragrance, and good quality. The north is cool in autumn and is suitable for the growth of celery. However, in the winter cold, small and medium arch sheds should be used for cultivation. After the cold, cold beds are used for the prosect storage. The storage period can reach 50-60 days. The supply will be listed on the market in the next 2-3 months, and the benefits will multiply, during the Spring Festival, the wholesale price. Between 0.6-0.8 yuan, the net income of Mu is 6000-8000 yuan. Now the cultivation time and the technique of pre-planting are described as follows: I. Cultivation techniques 1. Seeding and raising seedlings. The seedlings will be planted at the end of July and early August, and seedlings will be sowed after celery germination. The seedbed is leveled, and the seedlings are finely irrigated, and the cover covers fine earth O.5cm. Seedlings are grown when they are 4-5 leaves long. 2, cultivation points. Mushi basal fertilizer 5000g, deep turning, leveling. Row spacing by 2020cm. Two small waters are poured during the seedling stage and the seedlings are suitably planted. During the growing season, the soil should be kept moist, and the water should be poured carefully. At the same time, the fertilizer should be topdressed appropriately. The nitrogen fertilizer should be used as the top dressing, and the application of phosphorus and potassium fertilizers should be taken into consideration. Pre-frost cover film, when the temperature drops below 0°C, it is stored under preserving. Second, the preservation of storage technology 1, storage methods. Cold bed storage. The width of the cooling bed is about 1.5cm, and the depth is determined by the height of celery, usually about 1m. The distance between the top of the celery and the cover after the leave is 0.5m as a buffer space, and the use of thermal insulation, antifreeze and ventilation. 2, pretending technology. The celery was riddled with soil and rooted in a bed in clusters for ventilation and heat dissipation. Every 1m or so, a bunch of straw was placed between the celery and the water was immersed in the roots. Afterwards, the water was then 1-2 times depending on the soil conditions. After planting, the bed is covered with straw or roof covering. Leave vents at all levels and maintain a temperature of about 0°C throughout the storage period. Do not injure or get cold. When the temperature is too high, proper ventilation is required to reduce the temperature, and when the temperature is too low, grass is covered. Prevent the inflow of rainwater. Snow will be removed in time after snowing. This will be stored until the Spring Festival.
