Planting point:
It is not recommended to use seeds, which will be slow and thin, with fewer leaves and fewer flowers. Claw roots are recommended. There are many fakes on Taobao. A claw root is broken into n parts, and the color is wrong. I saw a shop with many colors and beautiful colors. It was probably Suqian goods from other place names.
It is suggested to sow claw roots in September-65438+10 to accelerate germination. This part is the key to success. Many people bury their claw roots directly in the soil and then water them, and the results will rot or sprout for a long time. You can use paper towels or sand to accelerate germination. I didn't have any sand, so I used paper towels. Paper towels are wet, but they don't accumulate water, so keep them moist and don't soak them in water, or they will rot. Put it in the refrigerator and germinate slowly at low temperature to avoid rapid water absorption at high temperature and direct explosion of cells. When it slowly absorbs water at low temperature, it will become moist and plump, and then it can be transplanted into the soil.
morphological character
prevent
Herb, 5~ 15 cm high, with creeping stems, developed walking stems, slender stems, creeping to the ground and taking root step by step.
The perennial leaves of celery are fleshy, nearly round or kidney-shaped, with V-shaped notches. The leaves are 2~3 cm long and 1.8~2.5 cm wide, with 5~7 lobes at the edge, which are blunt and serrated. The lobed leaves are about equal to the sawtooth depth, the base is heart-shaped, the palmate veins are 7~9, and the leaves are sparsely short bristles. The petiole is 5~ 15 cm long and densely pilose on the stalk; Stipules membranous, obtuse or lobed at the top, 0. 1~0.2 cm long.
flower
Flowers are winding inflorescences scattered in the axils of leaves. Peduncle longer than petiole, 5~ 15 cm long, pilose. There are 18~26 flowers in the cluster, forming a spherical head. The pedicel is very short, with a length of 0. 1~0. 15 cm, and there are membranous, ovoid or obovate small total bracts at the base of the pedicel. Calyx-free teeth; Petals, acuminate, white or milky white; The style swells when it is young, bends outward after flowering, and the base protrudes. The flowering and fruiting period is from April to165438+1October.
fruit
The fruit is free, with a length of 0. 12~0. 15 cm, a width of 0. 1~0. 12, oblate, heart-shaped and smooth at the base. Mature often yellow-brown, with prominent middle and trailing edges. There are two antenna-shaped styles at the top of the fruit.
The soil is breathable and loose, add some base fertilizer. Slowly emerge, don't be impatient, don't always want to dig out or give up directly. It is much easier to wait for the buds to grow, and then they can be divided into plants with stems. See dry and see wet, because there is base fertilizer, light fertilizer can be used at seedling stage. I like half-yin and half-yang, but I can't be exposed to the sun, but it's okay to throw it outside the balcony, hehe. Don't let it grow in vain, or it will fall down.
This celery flower blooms in April-May and can last for more than a month. The flowering time of different batches and colors is slightly different After the flowers are in full bloom, they can be cut and kept in vases for a longer time. If you don't cut it off, the flowers at the back may not be as big as the first one. More water is needed when flowers bloom. See dry and wet, the soil should be loose and breathable, and there should be no stagnant water, otherwise the leaves will turn yellow and water will fall down. According to the fertility of the soil, apply 1-2 times of phosphorus and potassium fertilizer at the time of flowering, and then apply 1 time fertilizer after cutting the flowers, so as to cultivate the roots and reduce the amount of water until watering is stopped. Ranunculus ternatus will hibernate in summer. In order to save space, I will dig out the roots, clean them, dry them naturally, and then store them in sand or dry soil. It was not until the end of September of the following year 10 that it was dug out and put into the refrigerator to break the dormancy.
Variety classification
Benqin
This variety has strong growth potential, late bolting and few branches. Solid petiole, good quality, disease resistance and wide adaptability. The average plant weight is 0.5 kg, and the average yield per mu is 6000 ~ 10000 kg, which is suitable for open field and protected cultivation all over the country in spring and autumn.
Dongqin Jinnan
This variety has thick petioles, light green and delicious fragrance. The plant height is 90cm, the weight of each plant is 0.25Kg, and there are few branches, which is most suitable for winter production in protected areas.
Hard celery
The plant is tall, the leaves are dark green and shiny, the petiole is green, and it is seedling or semi-seedling. The weight of each plant is 0.25 kg, and the yield per mu is about 5000 kg.
celery
King of California
The plant is tall and strong, with a plant height of more than 80cm. Strong resistance to Fusarium wilt and boron deficiency. It can be listed 80 days after planting. The weight per plant is above 1Kg, and the yield per mu is above 7500Kg.
Soaking the root tuber with warm water for 2 ~ 3 hours before planting is beneficial to germination. Choose a sunny and well-ventilated place to plant on the ground, water frequently during the vigorous growth period to keep the soil moist, but avoid water accumulation, otherwise it will easily lead to yellowing of leaves; Apply thin fertilizer frequently before flowering, and then apply 1 time fertilizer after flowering. In the hot summer season, when plants enter dormancy, root tuber can be dug out, mixed with sand, stored in a ventilated and dry place and kept slightly dry until autumn cultivation. If the temperature and humidity are high during the growing period, it is easy to cause white growth, yellow leaves and stem base rot. In September ~ 10, the plant was divided, and the tuberous roots with rhizomes were broken and planted. There is a great difference between sowing and propagation, and it is often used for breeding and mass propagation. It germinates 30 ~ 40 days after sowing, and it needs cold protection when the temperature drops to 5 degrees Celsius. Transplanting when the seedlings grow three true leaves in the second year, keeping them moist and fertilizing once every 7 days. Remove early buds in time to promote seedling growth. Ranunculus ternatus completed the seedling stage from sowing to dormancy in the following summer, and then it can be propagated with tuberous roots. Planted in early September, the row spacing of ground plants is 20cm. Use pots with a diameter of 18 ~ 20 cm, and choose mixed fertile soil. From 165438+ 10 month, apply dilute liquid fertilizer 1 time every/kloc-0 day, and once every 7 days from February next year, and increase the fertilizer concentration. At the initial stage of budding, 3 ~ 5 robust buds are selected for each plant, and the rest are all removed for centralized nutrition. By promoting cultivation, flowers will bloom at the end of the year. The method is to bury bulbs in wet sawdust, treat them at a low temperature of 8C ~ 10C for 30-40 days, break the dormancy in summer, and then plant them in late September ~ 10C, and keep the temperature around 10C in winter.
Farming season
Celery is cultivated in the open field in North China, and the climate suitable for celery growth is the longest in autumn, so the yield, quality and cultivation area are also the largest. Celery can also be planted in various protected areas to achieve annual supply. Generally, 65438 is planted in greenhouse in spring+0 ~ February, planted in late March ~ mid-April, harvested in late May ~ July, planted in autumn, planted in mid-June ~ early July, planted in spring in early August ~ mid-September, and harvested in June+08 ~ 65438+February. Generally speaking, protected cultivation is mostly planted in early July, mid-July to early August, planted in improved greenhouse or solar greenhouse in September ~165438+1October, and harvested in June ~ March.
Sowing and management
Celery is difficult to emerge, so sandy loam with high terrain, convenient irrigation and drainage, loose soil and fertile soil should be chosen as seedbed. It is necessary to apply sufficient decomposed base fertilizer and more ring fertilizer to loosen the soil. In order to achieve rapid, complete and uniform emergence, seeds can be soaked 7 ~ 8 days before sowing to accelerate germination. Sowing in the middle and late June, first soak the seeds in cold water 12 ~ 14 for 24 hours, wash the seeds, dry them in the shade for a while, wrap them with a wet towel when the surface of the seeds is dry, and put them in the shade (15 ~ 20) to accelerate germination. Seeds can be sown when they are bare, and wet sowing method is often used, that is, the bottom water is poured first and then mixed with sand for sowing. Build a shade shed on the seedbed to cool down, prevent sun and prevent heavy rain.
