How long is the general growth cycle of Chinese cabbage planted in summer?

In summer, there is plenty of sunshine and rain, and Chinese cabbage can be planted all year round, and summer planting can be planted in May and June, and the growth cycle is about 50 days.

Since the autumn and winter Chinese cabbage is sown in early autumn and harvested at the beginning of winter, the sowing period requirements are quite strict, and the time of sowing and harvesting is 1In the northern, northwest and northeastern parts of North China, autumn and winter Chinese cabbage is generally sown in mid to late July, and harvested in mid to late OctoberThe southern part of Northeast China, the central and southern parts of North China and the Huanghuai region are generally sown in early August, harvested in early and mid-November, and the cultivation of Chinese cabbage suitable for wintering is generally sown in mid-September or early October, and harvested at the end of the year or in January and February of the following year.

Chinese cabbage is a green leafy cruciferous crop, which is relatively simple to cultivate, and can be sown all year round in most parts of the country. Generally, about 500 grams of seeds are needed per mu, fertilization before sowing, land preparation to do furrowing, and the furrow surface is flat, and it is best to spray the furrow surface before sowing, and then sow the seeds. In summer, it is necessary to cover the shade net and uncover it in time after the seedlings emerge.

Maintain the humidity of the field at about 60 percent, and harvest about 20 days in summer after sowing, about 35 days in spring and autumn, and about 50 days in winter. Pay attention to prevent jumping nails, ape leaf muscles can be turned to distinguish snow glass grinding insects, cabbage insects

The appropriate planting of spring Chinese cabbage can effectively adjust the off-season in early summer and increase the variety of flowers in the market, which is of great significance to the anniversary of vegetables. However, the length of spring time is not the same, often the climate change is larger, it is difficult to be accurate, the period that is really suitable for the growth of Chinese cabbage is shorter, and the temperature change in spring is from low to high, which meets the needs of Chinese cabbage reproductive growth, but is not suitable for the needs of vegetative growth, so if the cultivation and planting of spring Chinese cabbage is not handled properly, it will often bring a series of difficulties and problems.

Summer Chinese cabbage, also known as early-maturing Chinese cabbage, has strong heat tolerance and short growth period, and only takes about 55 to 60 days from sowing to core harvesting. It is sown from mid to late July to August, and can be harvested from early September to mid-October. Because the growth period of summer Chinese cabbage is in the hot and dry season, it is necessary to water more and control various pests and diseases.

The insect pests are more serious to aphids, jumping capes, moths, and insects. The disease is the most harmful to soft rot, if not harvested in time, stop watering 5 to 7 days before harvesting, and wrap the core.

Eighty or ninety percent can be harvested and marketed, otherwise it will aggravate the harm of soft rot.

Autumn Chinese cabbage is sown late according to the growth and development law of Chinese cabbage and the requirements of environmental conditions, and is generally sown after the beginning of autumn, so as to avoid the high temperature period in late summer and early autumn, and the growth cycle is longer. The seedling stage is generally from the beginning of autumn to before the white dew, the core stage is from the autumn equinox to the beginning of winter, the rosette stage is from the white dew to the autumn equinox, and the core stage is from the autumn equinox to the beginning of winter. Generally, at the beginning of l1, that is, before the beginning of winter, when the minimum temperature drops to about zero degrees, cut vegetables in time, and when there is no serious frost climate, you can take measures to promote the heart of the vegetables, and appropriately postpone the date of cutting vegetables.

Although it can be grown at different times, Chinese cabbage also has a suitable growth cycle. Generally speaking, the planting period: the average monthly temperature suitable for planting is 15-18, the highest is 21-24, and the lowest is 7.

Germination period: generally in 20 25 germination fast and robust, 26 30 rapid germination but thin seedlings, higher than 30 poor growth. Seedling stage:

The suitable temperature is 22 25 and can also be adapted to 26 30. Rosette stage: the average temperature of 17 22 is the most suitable, too tall leaves are long, too low to grow slowly.

Bulging period: The optimum temperature is 12 22. Wrapping period:

Below -3, it is susceptible to frost damage. Storage: The temperature is 0 2, the relative humidity is 85% 90%, the temperature drops below -2, and the cabbage is frozen.

When is the best time to grow Chinese cabbage? Why?

Chinese cabbage is more suitable for planting in August and September, but there will be some differences in the planting time of different species. Some mature varieties will be sown in early August, while mid-early maturing varieties must be sown from mid to late August to early September, and late maturing varieties are more suitable in mid to late August. With the development of greenhouse technology, Chinese cabbage can now be sown according to the time period.

Spring cabbage should be sown in March and April in spring, summer cabbage should be sown in May and July, and autumn cabbage should be sown in August and September, and some areas will sow autumn cabbage as early as the end of July.

Chinese cabbage should be selected to be rich in organic matter, soft and rich sandy soil to sow seeds, before sowing must be subsoiled, tillage, leveled after furrowing, furrowing, and add sufficient base fertilizer. Before sowing, the soil should be watered with water from the bottom of the feet until the seeds germinate and are excavated, and the soil should be kept moist. After 2-3 leaves of the seedlings, a replenishment of seedlings should be carried out, diseased and weak seedlings should be pulled out, and weeds should be eliminated.

When 5-6 leaves of the seedlings have emerged, they can be planted and transplanted. After transplanting, the seedlings should be replenished with water in time to keep the soil moist and promote the survival of the seedlings. In the case of Chinese cabbage growth and development, a lot of chemical fertilizer is required, and in the case of abundant base fertilizer, appropriate ammonium sulfate must be topdressed after planting.

and properly watered; In the rosette stage, it is necessary to top dressing an appropriate amount of calcium carbonate.

and ammonium sulfate. <>

On the third day of planting, the second watering makes most of the buds excavated. Chinese cabbage is grown in most places in China, and Chinese cabbage is preferred in the cold natural environment.

Medium growth and development. The most suitable environment for development is between 15 and 22 degrees. If the ambient temperature is higher than 25 degrees, cabbage.

It will not be good. The growth and development of Chinese cabbage must have sufficient light.

If cabbage is grown in the open field, most of it is planted around the time of the cold dew in China. In fact, it depends on the variety of Chinese cabbage planted.

Chinese cabbage prefers a cold environment, and the suitable temperature for growth is between 15 and 22 degrees Celsius, but at the same time, Chinese cabbage also needs sufficient light to grow. In the north, sowing is usually done around mid-August, while in the south, where the temperature is a little warmer, it is delayed until around September, and early-maturing cabbage varieties are generally selected. Spring Chinese cabbage is generally grown in March and April.

It is in the spring, because the climate is suitable at this time, it is not very cold, and it is suitable for the growth of cabbage.

The best time to plant is in the spring, when the cabbage will be healthier and fatter and whiter and look greater.

The cabbage growth cycle has two months, generally the cabbage sown in July in autumn can be harvested from September to October, and the planting of cabbage should take the method of sowing, sowing the seeds with full grains in the soil, and watering a week later.

The seeds will germinate, and at this point they will be given well-rotted farm fertilizer to allow the cabbage to grow vigorously.

1. Growth cycle

The growth cycle of cabbage is in the range of fifty to sixty days. Cabbage is sown in July and August every autumn, and the plants will grow and mature in September and October, and when the cabbage is harvested, it is cut from the roots with a knife and the outer layer of rotten leaves is thrown away, leaving the inner leaves without damaging health.

2. Sowing and planting

When sowing and planting cabbage, the soil should be turned deep to dry, and the rotten organic fertilizer should be splashed to improve the fertility of the soil, and then the cabbage seeds with full grains and no pests and diseases should be sown in the soil and covered with fine soil.

3. Provide moisture

Cabbage has a greater demand for water, in the process of breeding, it should be watered every other week to keep the soil moist, but cabbage is afraid of waterlogging, in the rainy season should be loosened for it, drain the excess water, so that the plant grows healthily.

4. Supplement nutrients

Cabbage has a small demand for nutrients, but regular fertilization can make it grow more robust, so when breeding, it should be provided with rotten farmhouse fertilizer after the cabbage emerges, and nitrogen fertilizer and urea should be provided for the cabbage during the growing season.

and phosphorus and potassium fertilizers to allow the plants to absorb balanced nutrients.

There is no time limit for Chinese cabbage sowing, but it is best to choose it in August-September. It has a strong ability to adapt to the environment, and the general growth period is about 55 days, and it can be harvested and marketed when it is mature.

Cabbage Extension Material:

1。Sowing date.

Early-maturing varieties are generally sown before mid-August, medium-maturing varieties are generally sown in late August, and some late-maturing varieties are even sown in early September, and late-maturing varieties are suitable for sowing at the end of August and early September.

2。Key points of seedling felling.

The emergence time of Chinese cabbage is 3-4 days after sowing. It can be seen that the germination time of Chinese cabbage* is on the ground. When the Chinese cabbage has 2-3 true leaves, the first thinning can be performed. 5-6 leaves are the second thinning, and 7-8 leaves can be thinned.

3。Fertilization of the land.

Combined with cultivated land, apply sufficient amount of basal fertilizer in the field. It is advisable to prepare the land in time, plough evenly, rake finely, and plough about 30 cm. In addition to organic fertilizer as base fertilizer, it can also be mixed with chemical fertilizer as base fertilizer, which is recommendedWater-soluble fertilizer for sea mealsIt is completely soluble in water, and will not cause fertilizer damage even if it is used for a long time.

Generally, flat or high edge planting is used in the north, and high edge planting is mostly used in the south.

4。Field management.

After the Chinese cabbage seedlings emerge, the seedlings should be checked in time, make up for the shortcomings, and be carried out as soon as possible; After 3 days of emergence, a seedling thinning can be carried out, and when there are 3 to 4 true leaves, a second seedling thinning can be carried out to prevent excessive growth. After the four leaves are single-minded, the seedlings should be set in time to maintain healthy seedlings. At the seedling stage, it is necessary to pay attention to watering, do not dry, and at the same time carry out tillage and pine trees to achieve strong seedlings.

In order to obtain the best yield, nutrients must be supplemented at different growth stages. Generally speaking, the application of fast-acting nitrogen fertilizer at the early growth stage and heading stage has a better effect on increasing yield.

Chinese cabbage planting time.

There are many varieties of cabbage, and they can be sown all year round, but it is best to sow in March and April in spring or August and September in winter, which not only has a high survival rate but also a high yield.

Chinese cabbage growth cycle.

The growth period of Chinese cabbage is about 55 days, and the growth and development cycle is divided into two stages: vegetative growth and reproductive growth. Specifically, four stages are distributed: budding stage, seedling stage, rosette stage, and bulboding stage.

Chinese cabbage planting costs and profits.

Chinese cabbage has an average yield of about 10,000 catties per mu, which can be sold for more than 4,000 yuan per mu, with a cost of about 500 to 800 per mu and a profit of about 3,000 per mu.

Key points of Chinese cabbage planting technology.

1. Choose good varieties: When choosing varieties of cabbage, it is mainly necessary to consider according to the local climate and environment and market demand, and the varieties with high disease resistance are the most selected.

2. Soil preparation and fertilization: Before planting, cabbage should be ploughed, base fertilizer should be applied, and a cherry blossom should be used to make the ridge bush with fully rotted organic fertilizer and compound fertilizer.

3. Sowing method: cabbage can be sown and transplanted, if the time is relatively sufficient, direct sowing can be used, and direct sowing is about a week later than transplanting.

4. Field management: top dressing when planting cabbage is decided according to the growth cycle and growth of cabbage, try to choose nitrogen fertilizer and phosphate fertilizer, and water cabbage after top dressing.

Chinese cabbage planting time.

Chinese cabbage varieties are very juvenile and can be sown all year round, but it is best to sow in March-April in spring or August-September in winter, which not only has a high survival rate but also a high yield.

Chinese cabbage growth cycle.

The growth period of Chinese cabbage is about 55 days, and the growth cycle is divided into two stages: vegetative growth and reproductive growth. It is divided into four stages: germination stage, seedling stage, cluster stage, and fruiting stage.

The cost and profit of planting cabbage in Da Mo Qi Tong.

The average yield of Chinese cabbage per mu is about 10,000 catties, and it can be sold for more than 4,000 yuan per mu. The cost per mu is about 500 to 800, and the profit per mu is about 3000.

Key points of Chinese cabbage planting technology.

1.Selection of varieties: When selecting Chinese cabbage varieties, the local blind climate environment and market demand are mainly considered, and the varieties with strong disease resistance are the most selected.

2.Land preparation and fertilization: Before planting Chinese cabbage, it is necessary to plough and apply bottom fertilizer.

Generally, fully decomposed organic fertilizer and compound fertilizer are used. 3.Seeding Method:

Cabbage can be sown and transplanted. If you have more time, you can use live streaming. The seedlings emerge about a week later than transplanting.

4.Field management: Top dressing of cabbage planting depends on the growth cycle and growth of cabbage.

Try to choose nitrogen and phosphorus fertilizers, and water the cabbage after top dressing.

The growth cycle of Chinese cabbage is generally about 55-65 days, and the growth cycle of Chinese cabbage is generally about 90 days from sowing to harvesting. The growth period of different varieties is different, and the growth period of early-maturing Chinese cabbage is 50 to 60 days. Vegetable seeds grow rapidly, and cabbage sown in July in autumn can be harvested from September to October.

Chinese cabbage is relatively hardy and prefers a cold climate, so it is suitable for growing in the cold season.

Chinese cabbage growth rate.

Vegetable seeds grow rapidly, and cabbage sown in July in autumn can be harvested from September to October.

Germination Period:From seed germination to cotyledons, true leaves are revealed.

Seedling stage:From the appearance of the true leaf to the formation of a leaf inflorescence.

Romatic period:The plant exhibits 1-2 leaf inflorescences, which is the main period for the formation of individual yields. Flowering and fruiting period: The flower buds grow and bear fruit one after another.

Chinese cabbage growth cycle management.

Temperature Management:The resistance to low temperature is very strong, after the temperature reaches -3, if the temperature can gradually rise, it can also resume growth, but if it reaches -8, when the temperature continues to drop to about -11, it can not resume normal growth and suffer from frost damage.

Fertilization Management:15-20 nitrogen, phosphorus and potassium compound fertilizers were applied at the rosette stage; At the initial stage of balling, 667m2 was top-applied with 30-40kg of nitrogen, phosphorus and potassium compound fertilizer; No top dressing within 20 days before harvesting, combined with spraying in the rosette stage to start spraying 1 leaf let take the face fertilizer every 7-10 days, a total of 2-3 times, the use of urea and potassium dihydrogen phosphate mixture, at 16:00 to spray after the slippery Qi.
