Do you have to water the cabbage right after planting?

Chinese cabbage is a kind of vegetable that people often eat in their lives, and it is good to stir-fry and stew soupAlthough the climate varies depending on the season, it can generally be planted all year round, so you can buy the right variety.

Cabbage in the planting before the land to water the ground, and then planting, generally 3 to 4 days of time the seeds will emerge, if it is planted in summer, because the temperature is high, so you need to water more, to keep the soil moist, other times according to the wetness of the soil to water, even if the temperature is not very high, can not let the soil too dry. Do not water the cabbage before it sprouts to avoid overgrowth.

When the cabbage emerges, there is no need to rush to water, it should be watered immediately after planting, and it should be completely watered, and it should be watered once a day after 3-5 days of planting.

After that, the watering should be adjusted according to the climate, if the weather is very dry, you can water it frequently, to ensure that there is enough water in the land for the growth of cabbage.

Cabbage is a long-day plant, generally speaking, there is no need for shading treatment, but the temperature is too high, exposure to the sun is not conducive to the growth of cabbage, like the temperature in some areas in summer is more than 35, if it is not a heat-tolerant cabbage variety, it is necessary to do proper shading treatment, cabbage can grow well, and other seasons generally do not need shade.

With the growth of cabbage, the growth is inevitably uneven, some do not grow well, the leaves are withered, or diseased, and these leaves are not good if they continue to be kept, affecting the ventilation between the cabbage trees, the rot of the leaves is easy to be insected, and it is easy to become a hiding place for pests, and the insecticide is inexhaustible, so it is necessary to clean it up in time.

*Just after planting the cabbage, you need to water it immediately**. Because the cabbage is relatively shallow, the depth is about one centimeter, if the planting is not watered immediately, the cabbage seeds will not be dried and germinated, because the cabbage is planted in the dog days, the weather at that time is very hot, and the sun is still very poisonous, easy to dry. Therefore, when you plant the cabbage, you should water it immediately, and water it again the next day to let the cabbage seedlings grow.

However, it should be noted that the frequency of watering should be adjusted according to temperature changes.

Before planting cabbage, the soil needs to be tilled to increase the air permeability of the soilBefore sowing, bury the phosphorus and potassium compound fertilizer in the soil, and the burial time is best the day before sowingThe excellent cabbage seeds are germinated, covered with a layer of fine sand on the soil after sowing, and watered once in the morning and evening after 3 days, and cabbage seedlings can grow after 7 days.

1. Plough the land.

Before the cabbage planting technology, the planting soil needs to be ploughed, and the depth of the ploughing soil is about 5 cm to appropriately increase the air permeability of the soil; It is best to plough when there is sun, spray appropriate pesticides after ploughing, and clean up the germs and pests in the field.

2. Fertilize before sowing.

Fertilization before sowing can provide nutrients for cabbage growth, and also minimize the normal harm of fertilizer to cabbage when fertilizing at the seedling stage; Try to choose diluted phosphorus and potassium compound fertilizer for fertilization, mix the soil and fertilizer evenly, and the fertilization time is best carried out on the day before sowing.

3. Planting method.

Select the seeds of excellent varieties, and then put them in warm water for germination, pick them up and dry them after two hours, an acre of land needs about 150 grams of seeds, sow them out in the way of strip sowing, and use fine sand to spread evenly on the surface of the soil after strip sowing, and wet the soil with water.

4. Seedling planting.

Do not need to water for 3 days after sowing, wait for the seeds to adapt to the new environment; After 3 days, water once in the morning and evening, each time to ensure that the soil is moist, and seedlings can grow after about a week; The row spacing of seedlings should be kept at about 30*30 cm, so that they can be better illuminated.

Cabbage watering is particular, do a good job in watering management in these periods, cabbage grows strong and high-yielding.

After the cabbage is planted, it is followed by the management of the various growth periods of the cabbage, how to water the cabbage throughout the growth period is more conducive to the high yield of the cabbage, and it is also particular, Mr. Fu will share some management experience on cabbage watering.

1) First of all, the bottom water should be fully watered.

Growers should water the bottom water once according to the soil moisture before sowing to create moisture, and at the same time reduce the soil temperature, which is conducive to seed germination and reduces the probability of virus disease and downy mildew.

2) Watering at the seedling stage.

The cabbage seedling stage is small, the leaf area is not large, the transpiration effect is not strong, and the water requirement is also less, but the root system is not developed, and the deep soil water can not be used, and the temperature is still relatively high at this time, so it is necessary to water a little water frequently in the drought to make the soil moist, so that the seedlings can not only meet the need for water, but also reduce the ground temperature locally.

Generally, the watering of seedlings at the seedling stage is an effective measure to avoid the occurrence of viral diseases and cultivate strong seedlings. i.e. the first watering 24 hours after sowing; The seedlings are watered a second time when they have just been unearthed in small amounts; Water the seedlings for the third time after they are fully established; The seedlings grow to the pull cross stage, and the seedlings are watered for the fourth time after interspersing; The true leaves appear to about 10 pieces, and then water the seedlings again. At the same time, attention should be paid to the drainage of seedlings to reduce the occurrence of black rot and soft rot in the later stage.

3) Watering during the rosette period.

The rosette stage cabbage plants gradually grow, the growth rate is accelerated, the root system is also deepened, and the need for water is much greater than that at the seedling stage, and the water must be sufficient. However, at the same time, the water should not be too much, so as not to delay the bulbosetting period due to the growth of rosette leaves. Generally, the soil is watered thoroughly immediately after the application of fertiliser, and the soil is kept dry and wet during the rosette period.

If the plant grows in the late stage of rosette, it is necessary to take squatting measures. This is done by watering once 7 to 10 days before the balls are set, and then stopping the watering until the leaf color becomes dark green, thick and wrinkled, slightly wilted at noon, and the edge of the center of the plant is green. Watering should not be too much after squatting to prevent the petiole from cracking.

4) Watering during the balling period.

The balling stage is the fastest growing period of cabbage, which requires a lot of water, and often uses furrow irrigation or watering to increase soil moisture, and the frequency of watering can be determined according to the climate and soil moisture status. If there is no rain for a long time or the soil is dry, it should be watered to keep the soil moist as the standard. It rains a lot or the soil has a "night tide" characteristic, so there is no need to water the soil if it is wet.

Generally, after the first watering at the end of squatting, it is necessary to wait before the soil is yellow and moist, and then watered for the second time. After the second watering, water every 7 8 days until 7 8 days before harvest, watering evenly and consistently, keeping the soil moist.

Is it late to plant cabbage in September?

Cabbage is originally distributed in North China, and is widely cultivated throughout China. Cabbage is hardy, prefers cold climates, and is not suitable for planting on clay soil with poor drainage. When watering cabbage, choose the right time.

When setting seedlings, it is usually necessary to water them in time, and they also need to be watered once when they are thinning. When the cabbage is in the early rosette, it needs to be watered to promote the growth of the cabbage. Watering requires a small amount.

Water it sparingly, and when the cabbage begins to wrap the heart, it should be watered once. Chinese cabbage requires high soil moisture at the seedling stage.

2. The seedling stage is in the high temperature and dry season, and it is generally required to water once in 3 or 4 days, so as to achieve "three water seedlings, five water trees".

3. Chinese cabbage is generally "squatting" for 4 6 days after the seedling water, combined with top dressing and watering 1 time, and then generally watering once every 6 7 days to keep the soil moist.

4. The rosette stage of Chinese cabbage is the period when the outer leaves enter the period of rapid formation and development, and the roots are diluted 200 500 times with more than 5 kilograms of roots per mu or applied with watering.

Before planting cabbage, the ground is thoroughly watered, and then planted, after planting, pay attention to covering and moisturizing, and then watering after the seeds germinate, and then watering the seedlings when watering, and so on after the seedlings are planted, you can flood irrigation, but after the flood irrigation should be used with a watering can.

It can be watered, but it is best to do so in the morning or evening; After the seedlings emerge, the second seedling is thinned at the stage of 2-3 true leaves. Leave 8-10 plants and 3-5 plants each time, and set seedlings when 6-8 true leaves. In high temperature and drought years, the seedlings should be set late to make the seedlings denser to cover the ground to reduce the ground temperature and reduce the occurrence of virus diseases;

In low temperature and rainy years, the seedlings should be set early, so that the seedlings are evacuated, and the sunlight is more acceptable, so that the seedlings can be stretched as much as possible. The following principles should be mastered for seedlings and seedlings: leave strong seedlings to weak seedlings, leave seedlings in the middle of the row to go to the seedlings of the ridge state, leave the color of the positive seedlings to remove the variegated seedlings, and leave the good seedlings to the eccentric seedlings and seedlings without growth points.

If this time is in the high temperature season, it is necessary to water once to reduce the soil temperature, and apply 4-5 kg of urea with the water, and water it in the morning or evening. When the cabbage grows to 6-8 true leaves, the seedlings should be fixed. Due to the drive of interplucking seedlings, the root soil of the seedlings left behind is moved, and it should be watered once in time to prevent and avoid wind damage to the roots, so as to facilitate the root system to be strong and develop and grow.

Cabbage is not too late to need to be watered every day, seedlings when the cabbage 3-5 days watering can be, spring is the growing season of cabbage, at this time do not need to be too frequent watering, keep the soil moist, to the summer about 2 days to water, autumn 3-4 days watering, winter greenhouse planting to keep the soil moist, spring and summer watering as far as possible to choose the afternoon, at this time the temperature is not high, conducive to root absorption, autumn and winter can be watered some time in advance, the water source is mainly well water.

Cabbage does not need to be watered every day, under normal circumstances, wait for the cabbage seedlings to emerge 3-5 days after watering on the line, the specific watering time needs to be decided according to the season, spring and summer, mostly high temperature and rainy season, pay attention to drainage in the rainy season, dry weather about 3 days to water once, autumn and winter weather gradually cooler, watering times gradually reduce on the line.

If the weather is better and the climate is drier, the watering interval should be shortened as much as possible, if it is rainy, there is no need to water in a short time, and then water after the soil is dry, and the water source can be well water, river and lake water.

The correct way to water bok choy.

1. Planting season.

Chinese cabbage is generally planted in spring and the season that is about to enter autumn, and the spring cabbage is called early cabbage, and the autumn cabbage can be eaten next to the chop after winter.

2. Watering after planting.

Usually change the pot or just planted cabbage only need to water a small amount of water, and then wait for the soil to dry slowly, and then water some water after drying, not too much water and then wait for the cabbage to grow.

3. Water when you grow up.

When the cabbage grows out, water it properly, remember that the water should not be too large, so that after the cabbage is loosened, the cabbage is easy to fall with the wind.

4. Water control. After the cabbage is bigger, it is necessary to let the cabbage dry for a period of time to let the cabbage's roots deeper, you can also draw water for irrigation, and then wait for the cabbage to grow up and use the soil to accompany the cabbage around.

Cabbage is overwatered and handled.

Lodging phenomenon will occur after excessive watering of cabbage, at this time it is necessary to loosen the soil and discharge excess water in the soil, or you can put the cabbage in a well-ventilated environment, use the wind to evaporate water, and in the later stage of maintenance, you can water the cabbage after the soil is dry, and suspend the water supply when the soil is wet.

Water every 5-7 days in spring and autumn to ensure that the watering must be thorough. Water every 2-3 days in summer, and in winter when the weather is cold. Cabbage has different watering requirements in the growing period of different hail widths, when the sowing is completed, it needs to be watered immediately, and this watering should be watered thoroughly to ensure that the water penetrates into the bottom layer of the soil.

Then wait until the cabbage plants grow to 5-10 cm, and then water.
