How can celery be planted in winter to thrive?

Celery is very popular among people. The main cultivation methods are open field cultivation in spring, summer and autumn, and protected cultivation in autumn and winter. High quality, high yield and high efficiency were obtained when celery was planted in autumn and winter. Today we will talk about the planting techniques of celery in winter.

1. Release the seed from dormancy

Celery likes to be cold. If the temperature is higher than 25 degrees, it is very difficult for seeds to germinate. They can germinate successfully at 15 to 20 degrees, so summer sowing seeds must be treated at low temperatures. After soaking the seeds for 12 hours, they can be placed in a 10-degree refrigerator and treated at a low temperature for seven to eight days to release dormancy and then sow.

2. Shading and sowing

Choose the sandy loam with relatively high terrain and good conditions for drainage and irrigation as the seedling bed. The length of the seedling bed is 10 meters and the width is 1 to 1.5 meters. After sieving the rotten organic fertilizer, spread it evenly on the border surface, turn it into the soil, mix it evenly with the dung soil, then level the bed surface, pour water thoroughly, mix the treated seeds and fine sand evenly, sow it on the bed surface, and then cover the soil with fine soil two to three centimeters thick. 667 square meters require 50 to 80 grams of high-quality seeds and 30 to 50 square meters of seedbeds.

3. Pouring seedling bed water

After pouring the seedling bed water, the topsoil of the seedling bed should be kept moist. When the seeds are topped for seven to eight days, sprinkle water gently so that the seedlings can be unearthed smoothly and can be harvested within eight to ten days. When the seedlings have two or three leaves, pour water again.

4. Apply strong seedling fertilizer

Control three to four weed seedlings in time, apply a portion of available nitrogen fertilizer, and then apply fertilizer according to the situation. In summer, pay attention to foliar application of calcium fertilizer to prevent heart decay. As it is easy to die among celery seedlings in summer, after finishing the seedlings, the seedlings will grow together and the seedlings will be too thick. When the leaves are 02:00, the length of the second seedling is about one to 1.5 centimeters, the length of the third seedling is about four to five centimeters, and the distance between the seedlings is kept at three to five centimeters. The roots can be watered once after each seedling.
