Seed planting method and time of water celery in dry land

Seedbed: water celery likes shade and needs relatively loose and fertile soil to facilitate drainage and irrigation. Land preparation: the general width is about 1 meter, applying 2 kilograms of manure per mu. Sprouting: the seeds were soaked for about 2 days. Sowing: sowing in autumn from August to early September and in winter from September to late October. Management: in dry weather, water should be irrigated once in the morning and evening. After the seedlings grow together, they should start to fertilize and pay attention to pest control.

Recently, the price of water celery is not very low, but as there are many large growers, we do not have to worry too much. Even if the price is very expensive, you can choose to grow water celery yourself, because the method of growing water celery is similar to that of ordinary vegetables, but the requirements for moisture are more stringent, so how to grow water celery in the end? Let's take a look.

Planting method and time of water celery seed

I. seed planting method of water celery

1. Sowing and raising seedlings: the seed coat of water celery is relatively thick, which is not easy to sprout, so it is generally used to raise seedlings and transplant. when sowing in spring, do you need low temperature to deal with it? If you choose to sow seeds in autumn, you need to be treated at a low temperature. generally, you need to soak them in clean water for a day and a night before sowing, then take them out to dry, wrap them with gauze, and put them in the refrigerator to promote seedlings, or you can use the most traditional method to hang in a well, 40 centimeters above the water surface to promote germination, and when the seeds are 50% white, you can sow seeds, or you can use 5 mg / kg gibberellin soaking seeds to promote seedling germination.

2. Prepare the seedbed: apply base fertilizer at the bottom of the soil. Before sowing, the soil needs to be flattened and watered. When the water reveals all the soil, sow the seeds, then mix some fine sand to cover 3 to 4 mm of nutritious soil. The soil should not be too thick. Finally, cover with a film, which can play the role of heat preservation and waterproof.

3. Transplanting seedlings: 6 to 7 days is the fixed seedling period. At this time, fertilizer needs to be applied once a week. One mu can be 10 to 15 kilograms of urea or ammonium sulfate. It needs to be watered one day in advance before transplanting, which is convenient for transplanting. In this way, you can transplant with soil. The time of choice is probably fine weather. It is best to transplant when there is not much sunshine, such as after 4: 00 p. M. When transplanting, we need to pay attention to its distance, not too dense, the depth should not be exposed to the root, and finally pour some water.

2. Planting time of water celery seeds

1. Planting time of celery seeds in spring water

In cold areas, such as the northeast, seedlings are usually raised in 1 to 3 months, and the time to set seedlings is about March to April, while May to July is the harvest. The most suitable sowing time in the Yangtze River basin is March, if sowing prematurely, such low temperature is not conducive to growth, if sowing too late, it will affect the quality and its yield.

2. Planting time of summer water celery seeds

It is not appropriate to plant water celery seeds in summer, because the summer weather is relatively hot and rainy, which will affect growth, cause dead seedlings and reduce yield.

3. Planting time of autumn water celery seeds

Autumn is planted in the north, usually in the first ten days of June to July, seedlings can be raised, seedlings are fixed in the first ten days of August and September, harvest is from October to November, and the south is sown from July to early September, and the delivery time is from October to December. if late sowing is chosen, it can be harvested from March to April of the following year, when the south can be planted in the open field, while the north needs a greenhouse.

Planting technique of water celery in dry land

First, sowing and raising seedlings

1, nursery bed choice: water celery is like a cool climate, seedbed is a need for relatively loose soil, but also need to have a certain degree of fertility, convenient drainage and irrigation, in which one mu can be poured into 100 kilograms of lime to turn the soil.

2. Soil preparation: the general width is about one meter. Two thousand kilograms of manure can be fertilized per mu and then dried. Finally, the soil will be leveled and broken up, and a thousand kilograms of carbofuran needs to be added to eliminate earthworms in the soil.

3. Seed soaking and sprouting: put the seeds in a cloth bag, hang the cloth bag with a rope, hang it into the well, soak it for two days and two nights, or hang the seed 0.5 meters above the water surface for germination, usually it can sprout in 3 to 4 days, if there is no well, you can use the freezer to promote germination, that is, soak it in clean water for one day and one night, and then put it in the refrigerator.

5. Sowing at the right time: sowing according to the season, water celery in autumn needs to be sowed from August to early September, while in winter, it is basically sown from September to late October.

6. Seedbed management: good weather needs to be watered once every evening, while in relatively dry weather, water needs to be irrigated in the morning and evening. After the seedlings grow up, they will begin to be fertilized and once every 5 to 7 days. At this time, insect control is needed.

7. soil preparation and fertilization: to cultivate water celery, sandy soil is usually needed to retain water. 150 grams of quicklime is added to each mu of soil to turn the soil. then add 20 kg of urea, 10 to 15 kg of potash, 40 to 50 kg of phosphate, stir well, sprinkle it into the soil or water, flatten it, and wait for 4 to 5 days to plant.

Water celery is usually a place with a lot of water, and the cool climate is very suitable for the cultivation of water celery. If you want water celery to grow vigorously and have a high yield, there is no doubt that it is necessary to have good planting skills and control the planting time. It's very important for water celery.
