What is the method of growing watercress, and when is the best time to plant watercress?

Watercress is also called watercress, water mustard, watercress mustard, watercress planting method is also relatively simple, watercress is also a good choice when planting vegetables on the balcony, watercress taste very good has the effect of clearing heat and moistening the lungs, watercress contains a variety of vitamins have a good anti-aging effect.

Sow. WatercressThe watercress that can be bought in the vegetable market can be used directly for cuttings, and it is better to use the old stems, and it is easier to survive if there are adventitious roots. Cut the stalk of the watercress into small pieces of about 1 o 1 5 cm, each segment is about 3 5 knots.

Insert the cuttings diagonally into the soil to a depth of about 3 5 cm, preferably semi-lying, so that the stems are as close to the soil surface as possible, and water thoroughly, preferably maintaining a water level of about 1 cm. If you want to divide the plants, do it about 1 month after cuttings, with a spacing of about 1 o cm.

Day-to-day management. Watercress likes moisture and avoids drought, and often needs to be watered to keep the soil moist, and it is best to grow watercress when it is hydroponic, and the water level should be relatively shallow.

More fertilizer is needed, but it is best to apply all-element fertilizer, and spray 1 decomposed organic fertilizer every harvest. Watercress has fewer pests and diseases, and it is mainly eliminated by hand in a timely manner. If the insect infestation is severe, you can also add water to flood the plant, drown the pest and then drain the water.

Harvest. The watercress can be harvested at about 20 cm.

Precautions for watercress planting.

The main insect infestation of watercress is foliar pests. We can't use pesticides on our balconies, and we also want to grow pollution-free green organic vegetables, so we can use chili powder to repel insects and kill insects. To quickly cull a large number of pests, you can use aerosol insecticides that kill cockroaches and mosquitoes at home every day, with low toxicity and no residue.

For root pathogens, it can be watered with pepper water.

Watercress is afraid of both cold and heat. Below 15 degrees Celsius, watercress grows slowly, and the temperature is close to freezing, and it can freeze to death. When the temperature is higher than 30 degrees Celsius, watercress also grows slowly, and will age rapidly, with excessive fiber, and the color turns purple and red, with a strong bitter taste.

Therefore, when the seasons change, it is necessary to pay attention to cold and heat protection.

It is planted in the spring, because the light is better at this time, which is suitable for the growth of watercress.

The best time to grow is from August to September, if it is planted in the north, we must ensure that the temperature is sufficient, many people will choose to plant in greenhouses, if you want to grow watercress in the open field, the temperature must be suitable for the growth of watercress, otherwise it will reduce the yield of watercress, and it may also cause death.

Watercress is planted in March to May every year at a very opportune time, as the weather at this time is warmer, which is perfect for sowing.

Watercress can be grown in the following ways:

1.Sow. Watercress, which can be purchased at the vegetable market, can be used directly for cuttings, and the old stems are better. If there are adventitious roots, it is easier to survive.

Cut the watercress stalks into small pieces of about 10 to 15 cm, each slice has about 3 to 5 knots. The cuttings are inserted into the soil to a depth of about 3 to 5 cm, preferably semi-recumbent, so that the stems are as close to the soil surface as possible, watered, preferably at a water level of about 1 cm. If you are planting ramets, you should do it about a month after cutting, with a spacing of about 10 cm.

2.Day-to-day management. Moisten the cress to avoid drought. It is often necessary to water the soil to keep it moist. When growing watercress, it is best to plant water, while the water level is relatively shallow.

More fertilizer is needed, but it is better to apply all-element fertilizer, with one decomposed organic fertilizer per harvest. There are fewer pests and diseases in paddy fields, and manual elimination is one of the main reasons. If the pest is more severe, the plant may be flooded, and after the pest has drowned, the water will be drained.

3.HarvestCress can be harvested at about 20 cm.

Watercress is grown from late August to September in the following ways:

1. Planting selection.

1. Generally, you can choose to plant in paddy fields or dry land with convenient irrigation conditions, and the soil fertility of the planting place should be sufficient, and the fertilizer and water retention should be strong, so the soil is clayey soil or sandy land is not suitable for planting.

2. There should be appropriate shade around the watercress planting ground, which can reduce the labor and cost of building a shade shed, the paddy field should be ploughed, and the dry land should be deeply cultivated, and the foot fertilizer should be applied, and after the furrow is done, wait for sowing.

2. Field management.

1. Watercress has very high requirements for water and fertilizer, so there are certain differences in the management of paddy field planting and dryland planting.

2. If it is planted in a paddy field, then after planting, it is necessary to put shallow water in the field in time, generally with a depth of about 2cm, and then gradually increase the water level with the growth of watercress, and the water level in the field should not exceed 5cm.

3. If you plant on dry land, you need to water it after planting, and then water it once every 3-4 days, which is conducive to maintaining the humidity of the soil.

3. Harvest and retain seeds.

1. When harvesting watercress, it is necessary to harvest in batches, generally after planting, when the watercress grows to about 30cm high, you can harvest the first batch, and you need to fertilize once after harvesting, mainly with urea.

2. There are generally two types of watercress, namely seed propagation and asexual reproduction, seed propagation is to use seeds to retain seeds, and asexual reproduction is to select and retain plants, generally in May, the fruit of watercress will begin to enter the maturity period, and then you can leave seeds.

Watercress is generally planted in autumn and harvested in winter. From late August to September, when the temperature drops to 25, seedlings are planted or sown, planted in September and October, and harvested about 30 days after planting. In the Yangtze River Basin, after harvesting and replanting 2 3 times, when the temperature drops to 5, it needs to be moved to the large and middle sheds or protected areas for false planting for wintering, and then transplanted in the open field in March of the following year and harvested in April and May.

Watercress is also called watercress, and watercress mostly uses vegetative propagation, which is propagated by ramifications and cuttings. The nodes take root and survive quickly. The row spacing of the planting plant is 6cm 9cm, and after one month, the seedling grows 15 to 20cm, and when the stalk is thick, it can be planted separately.

After planting, maintain a certain water level or a moist state to facilitate germination and rooting. If the temperature exceeds 30, cool water should be poured in the afternoon to avoid scalding the shoots. After the plant grows up, the water level can be deepened according to the requirements of the landscape.

In the growing season, weeds should be removed in time, and top dressing should be applied 1 2 times in combination with weeding.

Varieties of watercress.

1. Guangdong small-leaved watercress: leaflet type, plant height 30-40 cm, stem thickness of about centimeters, 2-3 pairs of leaflets on both sides, apical leaflets oval, long cm. Centimeter wide, brown, flowering in late April, but not bearing fruit, only vegetatively reproduced.

2. British large-leaf watercress: large-leaf type. The height of the plant is 40-50 cm, the stem thickness is about cm, the leaflets on both sides are 1-3 pairs, the apical leaflets are round or nearly round, long cm, wide cm, green, cold hardy, and still do not change color at low temperatures and in winter.

It blooms and bears seeds in spring, with good quality and fresh taste.

3. River two-leaf watercress: large leaf type, plant height of about 40 cm, stem thickness of about centimeter, 1-3 pairs of leaflets on both sides, apical leaflets long ovate, 3 cm long, cm wide, leaf green, leaf veins red, do not change color in winter and low temperature conditions, flowering and seeding in spring. This variety is highly resistant to stress and cold, but contains relatively more fiber.
