Cultivation of special vegetable celery

Root celery, also known as root celery, bulbous root wormwood, etc., is a biennial herbaceous plant, introduced from Germany, the Netherlands and other countries. The crispy fleshy roots and petioles are used for eating. The nutritional value is better than that of ordinary celery, and the texture is crisp and fragrant. Its adaptability, low temperature resistance, resistance to storage, long supply time, is a promising new type of health vegetable.

Cultivate strong seedlings

In greenhouses or greenhouses and other facilities for nursery, the use of plug seedlings or nursery seedlings and other methods can be, but the seedlings seedlings easier access to strong seedlings. Because the celery seed skin is thick and hard, with oil glands, it is not easy to absorb water and germinate slowly and neatly. Therefore, seed must be soaked before sowing and rubbed by hand during soaking. Soaking when the water temperature 20 °C -30 °C, soaking time 8 hours -10 hours. Then wash the seeds, drain the water, mix well with the fine dry soil, and spread on the seedbed.

Ordinary seedbed nursery methods planting 1 mu need to nurse seedlings 15 to 20 square meters, with the amount of 15 grams -20 grams. Seedbed can be used flat or small sorghum, bed soil should be smashed and flat, fully applied fine crushing high-quality organic fertilizer 5 kilograms per square meter, must be poured first foot water. Seeds should be sown as thin as possible, sowing about 1 gram per square meter, which can save the separation of seedlings in order to reduce the damage to the root system. The optimum temperature for seed germination is 15°C-20°C. After the seed germinates, cover with "the seedbed net medicine soil (the seedling stage is easy to obtain the tripping disease), the thickness is 0.5 centimeters, does not need to water, prevents the soil from compacting, the seed develops by the bottom water of the nursery bed. After the young bud is unearthed and then waters, The principle of keeping the soil moist is to keep the soil moist.Plant seedlings are planted using 128-hole plug trays, with 1 grain per seed per seed, 2 seedlings, and 60 seedlings per acre for planting.

Generally after 10 days, the seedlings begin to sprout. Before seedlings must ensure that the seed parts are moist, and the seedlings for plug seedlings should pay attention to timely watering to keep the matrix moist. Summer shade must have shade measures. Before the emergence of surface drought, it is necessary to replenish water in a timely manner. When watering, it is necessary to slow down the small water and prohibit the flooding to prevent the seeds from being washed away. The conditions are suitable. After the seedlings grow on the soil, a layer of fine soil can be applied to protect the seedlings and solid seedlings. In the seedling stage, weeding, seedlings, and seedlings were separated by about 3 cm. The seedlings were applied 3 times to 4 times throughout the seedling stage and 0.2% of Baolifeng No. 1 was applied. Seedlings in seedlings were treated twice or three times with seedlings depending on soil fertility and seedling growth. At the seedling stage, we must pay attention to the prevention and control of aphids, whitefly, and thrips and other pests.

Soil fertigation

After harvesting the crops of the previous crop, the rotten leaves of the stubborn crops shall be promptly removed and transported to designated locations for ozone disinfection or harmless treatment such as high-temperature composting. Apply crushed fine-quality organic fertilizer 3000-4000 kg per acre. The soil should be intensively intensively cultivated, so that it should be flat, flat, finely crushed, and free of waste, and fertilize evenly. At a distance of 1.3 meters, it is made into 6 to 8 meters in length.

Colonization

About 60 days after sowing, the seedlings can be planted when they have 6-7 leaves, and they need to be watered one day in advance so that they will be less likely to injure the roots when planting, and they will be able to slow down the seedlings. Planting in flat ridges, planting 4 rows of 1.3 m wide pods with an average spacing of 30 cm to 40 cm, plant spacing of 25 cm, medium-early maturing cultivars, planting 5000 plants per acre and 6,000 planting plants, increasing plant spacing for late maturing cultivars, and planting 4,000 acre per acre About the strain. Colonization in summer and autumn should be better after 5 pm. When cultivating, the roots can be buried, and the roots of the celery seedlings can be buried too deeply. It is easy to cause the death of the seedlings. When the weather is hot, it is necessary to plant water while planting.

Field management

Management before root enlargement: timely cultivating tillage after easing seedlings, adjusting suitable temperature, timely ventilation and ventilation, seedling period is based on the principle of “less pouring and pouring”, leaf growing season, “land not irrigated, ground white” Only pouring, this stage for the period of flesh root swelling to play the foundation, combined with water once fertilizer, ample 200 kg of chicken manure per pound hole or nitrogen, phosphorus, potassium ternary compound fertilizer 15 kg. Applied around the roots, more than 5 cm deep.

Root enlargement to harvest stage management: The appropriate temperature is 15°C-22°C during the day and 10°C at night. It can also be seen from the morphology of the plant management temperature is appropriate, if the outer leaves of the root celery down rewinding, indicating that the root celery is growing roots, the temperature is reasonable. If the leaves grow upright and the new leaves grow rapidly, it means that the temperature, especially during the night, is high and the planting within the facility must be adjusted in time.

Into the root expansion stage requires more water, to keep the soil moist, with a small amount of ground water is appropriate, usually about 7 days pouring a water. Avoid flooding and prolonged drought. In the process of root enlargement, the lower leaves will cause the base of the leaves to crack due to the enlargement of the stem, and the old leaves, yellow leaves and lateral branches of the lower part of the plant may be promptly destroyed according to the growth of the leaves, and the lateral roots of the fleshy roots also grow. To be removed in time, is conducive to ventilation and light transmission, so that the main root hypertrophy, smooth surface, neat roots, and reduce the incidence of disease.

Harvesting

The bulb can be harvested when the coriander bulb grows to about 0.5 kilograms, and the big ball can grow to more than 0.75 kilograms. The big leaf of the outer layer can be picked up and the fibrous root can be cut off and sold. Due to the slow growth of celery, there are differences between individuals, which can be harvested at the time of harvest, leaving little to continue growing. The harvest period of genus is 1-2 months. If the cultivar is high in purity and grows neatly, it will be shorter. General mu production 2000 kg -3000 kg.
