Cultivation techniques and field management of celery

Celery is nutritious. It is determined that every 100 grams of edible part contains 0.7 grams of protein, 0.1 grams of fat, 5.0 grams of carbohydrates, 37.0 milligrams of calcium, 1.4 milligrams of iron, 45.0 milligrams of phosphorus, 11.03 milligrams of vitamin B11.03 milligrams and 21.20 milligrams of vitamin C10.0 milligrams. Spring is a good season for celery cultivation. Cultivating celery with Yifu source planting liquid is a method that can not only improve the soil, but also produce high yield.

Celery planting techniques in spring:

1. Prepare the land to make a bed

Celery is suitable for growing in loam or clay soil rich in organic matter, loose, fertile, water and fertilizer. Half a month before raising seedlings, the soil should be ploughed and whitened. Combined with ploughing, 4000-5000 kg of fermented organic fertilizer was applied per mu, proper amount of superphosphate and urine were used as base fertilizer, and some special compound fertilizers of wild vegetables containing phosphorus, potassium, calcium and trace elements (such as boron, etc.) were applied to supplement Peng and calcium nutrition to prevent the release of petiole crack disease and rotten heart disease. After finishing the land, make the border, the width of the border is 2 meters, and the surface of the border should be flat, thin and solid.

two。 Seed treatment and seedling raising

Before sowing, soak the seeds with Yifu source planting solution for 24 hours, keep it moist, and accelerate germination for 5-7 days at 18 ℃-20 ℃.

3. Sowing seeds

After sprouting, it can be sown, and the sowing amount is 50-100 grams for planting 1 mu of field. Pour enough bottom water before sowing, when the water seeps under the water and the soil is operable, use a hoe to ditch the border surface with a row spacing of 6-7 cm, spread the seeds evenly in the ditch, cover them with fine sand, with a thickness of 0.3-0.5 cm, and sow just one seedling bed (11 square meters) per seed. Sowing is best carried out on cloudy days or in the afternoon to prevent sunburn.

4. Colonization

After pulling the seedlings of the previous crops, the ground was leveled and 5000 kg of rotten organic fertilizer was fermented by Yifuyuan biological bacteria per mu and planted from the first ten days of January to the last ten days of January. Ridging, planting 2 rows per ridge, row spacing 35 cm, cultivating large trees, plant spacing 30 cm, hole depth 8-10 cm, planting 6000-7000 plants per mu; cultivating medium-sized trees, spacing 25 cm, planting 7000-8000 plants per mu. All of them are planted on a single plant, and the seedlings are watered and transferred in time after planting.

5. Post-planting management

In the initial stage of planting, we should try to improve the indoor air temperature and soil temperature, such as covering the planting ridge with thin film, building a small arch shed and so on. In the middle stage of celery growth, with the warming of the weather and the rise of room temperature, the small arch shed should be removed in time. When the room temperature is more than 25 ℃, it should be ventilated and cooled, ensuring that the room temperature is about 20 ℃-22 ℃ in daytime and 10 ℃ at night. In order to promote the growth and increase the yield in the later growth stage, the daytime temperature can be controlled by 20 ℃-22 ℃.

During the planting of celery in spring, Yifuyuan planting solution can be used to irrigate the planting water once with water, less or no slow seedling water, and loosen the soil once after slow seedling. In general, the ridge noodles are not watered when they are not dry, and when the ridge noodles are dry, they are only watered, and pay attention to ventilation and humidity reduction. During the early spring, it is appropriate to loosen the soil to increase the soil temperature, promote the seedling rooting and grow healthily. When the seedlings are as high as 15-20 cm and the true leaves are 5-6, celery enters the vigorous growth period, so fertilizer and water management should be strengthened. Generally 7-10 days, each mu with an appropriate amount of urea, such as planting bacteria solution 2-4 kg, with water topdressing. Irrigation for 3 times and topdressing for 2 times. Water should also be irrigated once a week before harvest.

The cultivation of celery in spring with Yifu source planting solution can improve the germination rate, improve the soil, inhibit bacteria, enhance the metabolic function of celery, and increase production and income.
