Planting cabbage in autumn, the harvest is particular, how to harvest the most correct?

Generally speaking, the cabbage wrap is seven or eight percent ripe, and it can be harvested in spring.

The earlier the spring Chinese cabbage is marketed, the higher the profit. General North China Plain area: when the core is seven or eighty percent, it can be harvested and marketed one after another.

Spring Chinese cabbage planted in the shed can be marketed in early May, seedlings transplanted in the open field cover film to cultivate Chinese cabbage in mid-May, and open field live broadcast can be harvested and marketed from late May to early June. If the harvest is delayed, the temperature is high and it is easy to rot, and the production value is reduced. High altitude cool areas:

As the altitude increases, the harvest lasts from early August to mid-September. Chinese cabbage varieties suitable for spring planting generally have poor storage tolerance, and it is not recommended to store them in winter in cold areas at high altitudes.

The harvesting standard of Chinese cabbage is based on the compact leaf balls. Generally, spring-sown and summer-sown Chinese cabbage must be harvested in time because the harvest period is in the high temperature season.

When planting cabbage, be careful to spray it with vinegar. Not only can it increase the yield of cabbage, but it can also remove insect pests.

The main thing is to wait for the next spring to be harvested when the cabbage is formed and undamaged.

When the fruit is ripe, it is usually harvested in the spring of the following year.

It is necessary to decide how to harvest cabbage based on the weather and rainfall experienced by planting cabbage this year.

Cabbage is planted in autumn, it is not like cabbage planted in spring, which is picked in a special way at harvest time.

When picking, it is necessary to choose the right time and pay attention to the technique so as not to destroy the integrity of the dish.

It should be harvested according to scientific methods, otherwise there will be a bad harvest.

Hello, autumn cabbage is generally sown 3-5 days after the beginning of autumn, if it is a high temperature season, it can be postponed in mid-August.

Water and fertilizer management: After the Chinese cabbage enters the balling stage, it needs the most water, so it is necessary to water it once after squatting. Then water again a second time every 2 3 days.

Water every 5-6 days thereafter to keep the soil moist.

Chinese cabbage yield is high, the amount of fertilizer is large, on the basis of applying enough water-soluble fertilizer in the sea and Weihai meal, it can be temporarily not topdressed, and the topdressing needs to be determined according to the different growth conditions and seedling stages of Chinese cabbage.

Autumn cabbage is generally planted around the beginning of autumn, if it is planted in the open air, it should be sown 5 to 6 days in advance, if it is planted in greenhouses, it can be planted about three days before and after the beginning of autumn.

The north can be compared to the same temperature reference.

Autumn and winter cabbage is generally small cabbage, which can be seeded live, and the process of seedling is the process of harvesting. Seedlings can also be transplanted, the sowing period is generally in August to December, the Yangtze River basin and the Huaihe River basin are generally harvested before the freeze, and South China can last until February of the following year.

Generally speaking, autumn cabbage with early maturing stubble should choose varieties with strong heat tolerance, good early maturity, outstanding high yield, and high disease resistance.

2. Sow seeds at the right time.

The sowing period of early-maturing autumn cabbage is generally around late July to early August, and about ten days before the beginning of autumn is the best, because it can be marketed before the National Day.

When the seedlings grow to 5-6 leaves, they can be planted or planted. The standard of strong seedlings is: plant height 10-15 cm, dark green leaf color, 5-6 leaf whorls and symmetrical, developed root system, no pests and diseases and mechanical damage, and no mixed varieties.

Thick plastic cloth cover tightly, surrounded by corn stalks to block tightly, when on the big freeze, when in the autumn cabbage all down, moved to the house, so that the autumn cabbage stored after harvest is very good, the cabbage to help you not break it will never take off. Harvested at the beginning of winter,Therefore, the requirements for sowing time are quite strict. The seedling stage is generally from the beginning of autumn to before the white dew, the rosette stage is from the white dew to the autumn equinox, and the heart stage is from the autumn equinox to the beginning of winterGenerally, it is harvested in time when the minimum temperature drops to about 0 before the beginning of winter.

High temperatures, heavy rainfall, weak seedling growth, poor root development, and susceptibility to diseases and pests. In addition, due to the rapid senescence of the root system under high temperature conditions, the senescence of the root system will cause the premature senescence of the whole plant, so that the dead leaves will increase in the later stage, and the shedding will be serious during storage. In this way, if the temperature is about minus 10 degrees, press a layer of plastic sheeting on top of the grass, so that it is okay, and this storage method can make the cabbage retain more moisture and freshness.

Basically, the rice can be planted after harvesting, and it can be advanced or postponed according to the climate temperature of the year. It's a month or two in the north than in the south. In addition, there is a difference between mountainous and plain areas, and the temperature in the mountainous areas drops early, which can be a little earlier.

Some of them are individually crushed and molded to be packed. If it is a medium-sized or small cabbage, the number of plants per mu is 2,000 or 3,000, and the seeds should be scattered in the same row, and the buried soil should be shallow and not more than half a centimeter.

Some of them are individually crushed and molded to be packed. If it is a medium-sized or small cabbage, the number of plants per mu is 2,000 or 3,000, and the seeds should be scattered in the same row, and the buried soil should be shallow and not more than half a centimeter. Cabbage radish has simple requirements for the geological environment, sufficient bottom fertilizer, and good moisture, as long as these two requirements are met.

For the autumn cabbage planting time in the countryside, it varies from place to place, and some places plant immediately after the beginning of autumn, while in our hometown of Hunan, this time is still the peak period for planting autumn cabbage.

Autumn cabbage does not need to be broken, because autumn cabbage is a naturally ripe variety, and every cabbage has already grown, so there is no need to break it manually.

Need, so that the cabbage can be more mature, so that the growth and development of the cabbage is better, so as to avoid frostbite of the cabbage.

It's best not to break the gang, if you break it, it is not easy to preserve, and you can save it for a longer time without breaking the cabbage gang.

Summer Chinese cabbage can be sown in May-June and harvested in July-August.

Since the autumn and winter Chinese cabbage is sown in early autumn and harvested in early winter, the sowing period requirements are quite strict. The time of sowing and harvesting is:

1.In the northern, northwest and northern parts of North China, autumn and winter Chinese cabbage is generally sown in mid to late July and harvested in mid and late October.

2.The southern part of Northeast China, the central and southern parts of North China and the Huanghuai region are generally sown in early August and harvested in early and mid-November.

Suitable for overwintering Chinese cabbage cultivation 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 cannot be cropped in succession or rotated with other cruciferous vegetables, which is one of the important measures to prevent pests and diseases. After the harvest of the previous crops, it is necessary to fertilize the land in time, and 4000 kg of organic fertilizer and 5000 kg of organic fertilizer, 25 kg of nitrogen, phosphorus and potassium compound fertilizer can be applied per mu.

Cultivation method: 1. Sowing. Sowing is divided into two types: direct seeding and seedling transplanting, which generally depends on the harvest of the previous crop. If the previous crop is harvested early, and the land can be prepared in time for furrowing, the direct seeding method can be used, otherwise the seedling transplanting will be used.

The seeding is 5 days later than the transplanting of seedlings and the sowing is carried out 6 days later. Chinese cabbage is generally cultivated in two modes: high ridge and flat furrow. High ridges are generally planted in a row per ridge, and the ridge height is 12 cm to 15 cm; Two rows of flat furrows are planted per furrow, and the width of the furrow depends on the variety.

There are two methods of live broadcasting: hole casting and channel broadcasting. Hole sowing is in the row or at the top of the ridge according to a certain plant spacing to open the hole, early varieties row spacing 55 cm 60 cm, plant spacing 40 cm 50 cm, about 3000 plants per mu; The row spacing of medium and late maturing varieties is 65 cm 70 cm, and the plant spacing is 55 cm 60 cm, with about 2500 plants per mu. The width of the hole is 8 cm 10 cm, the depth is about 1 cm, each hole is sown 5 grains 6 grains, and each mu is about kilograms.

Strip sowing is according to the row spacing to open 5 cm 10 cm deep ditch, first along the ditch watering, water infiltration, the seeds are evenly sprinkled in the ditch, and sprinkled with 1 cm thick fine soil, the amount of seeds per mu is about kilograms. After the young shoots of Chinese cabbage are unearthed, they should be watered frequently to keep the ground moist and reduce the surface temperature. In the absence of rain, it is usually watered on the day of sowing or the next day to ensure that the ridge surface is soaked through.

On the third day of sowing, the second water is poured to cause most of the young shoots to emerge.

2. Seedling management. After the seedlings emerge, the seedling work is carried out at the cotyledon stage, the cross stage, the 3-leaf and 4-leaf stages, and the seedlings are separated from the concurrent, overdense, crowded, diseased, insect, weak, and residual seedlings. Seedlings are set at 5 leaves and 6 leaves, and the seedling spacing is 10 cm.

In high temperature and drought years, the seedlings should be set late appropriately, so that the seedlings are dense, cover the ground, reduce the ground temperature, and reduce the occurrence of diseases. In addition, late seedlings also have the opportunity to uproot early-onset plants and prolong the selection time. When thinning seedlings, the seedlings in the overly dense place can be transplanted in the lack of seedlings.

Seedling replenishment should be carried out in the cool afternoon, and watering should be carried out in time after replenishment. After each seedling thinning and seedling, it should be watered immediately to prevent wilting due to the shaking of the seedling root system. This period is in the late rainy season, and disastrous weather such as heavy rain, high temperatures, and drought are more likely to occur during this period.

Plants grow rapidly at the seedling stage, but the root system is small and the absorption capacity is weak. Therefore, it is essential to top dressing and watering in a timely manner. In times of drought, water should be poured once every 2 days or 3 days to keep the ground moist.

In addition to replenishing water, watering also has the effect of reducing ground temperature, preventing high temperature from burning the root system of seedlings and inhibiting the occurrence of viral diseases. In high temperature and dry weather, in addition to timely watering, it can also be temporarily shaded and cooled at noon.

1.Select the variety. Generally, the plots with good fertilizer and water conditions are selected as tall, late and medium-ripening varieties; Dwarf and early-maturing varieties are selected for plots with poor fertilizer and water conditions.

2.Fertilize the land. Land preparation should be fine, combined with land preparation, apply 5,000 kg of high-quality farm fertilizer, 20 kg of diammonium or 50 kg of superphosphate, 25 kg of potassium sulfate or 30 kg of ternary compound fertilizer per mu.

After the land preparation is completed, the width of the ridge is 30 cm, the width of the ditch is 30 cm, and the height is 15 cm.

3.Sow at the right time. The sowing date of autumn Chinese cabbage should be determined according to the local climatic conditions and varieties, and the disease will be more serious if it is too early, and the yield will be reduced if it is too late. Live broadcast on the ridge according to the plant spacing of 35 cm (live broadcast does not need to slow seedlings).

4.Field management. Seedling management. Watering after sowing, and watering in time according to the weather conditions after the seedlings are set to prevent high temperature and drought from affecting the growth of seedlings. Cultivate in time after watering or after rain.

Rosette period management. Apply 10 kg of urea per mu, water in time after fertilization, and master the principle of seeing dry and wet in the future.

Pitching management. Apply 15 kg of urea per mu and water every 5 or 6 days to keep the soil moist and the moisture even. Stop watering 8 days before harvest to avoid excessive moisture in the spheres and cause rot.

5.Control pests and diseases. Prevention and control of Chinese cabbage diseases.

500 times of virus No. 1 oil emulsion for the prevention and treatment of viral diseases; Use 40% ethyl phosphorus aluminum 300 times solution to prevent and control downy mildew; 150 mg kg of agricultural streptomycin sulfate for soft rot control; Spraying manganese sulfate to prevent and control dried heartburn of Chinese cabbage.

Chinese cabbage pest control. Use 90% trichlorfon 100 times liquid to control jumping beetles; 10% imidacloprid 1500 times solution to control aphids; Use BT emulsion to control cabbage worms.

The best time to plant Chinese cabbage in autumn and winter is within five days before and after the beginning of autumn, and if there is plenty of rain at the beginning of autumn, it can be delayed by five days.

You can also choose the best planting time according to the planting varieties of Chinese cabbage in autumn and winter, if the varieties that need to be planted belong to the late-maturing varieties with a long growth period, they can be sown a few days in advance, on the contrary, if the planting varieties belong to the medium-ripening varieties with a short growth period, they can be appropriately delayed for a few days of sowing, and at the same time, they should be evenly sprinkled with rotted farmhouse manure in the process of land preparation before planting.

In the growth period of autumn and winter Chinese cabbage, apply potassium-containing fertilizers and maintain sufficient irrigation, so that the leaf bulbs of autumn and winter Chinese cabbage are full and full, and the plant bundles are tall, thereby increasing the weight and quality of the whole Chinese cabbage, so as to ensure a bumper harvest of autumn and winter Chinese cabbage and increase farmers' income.

In various regions, the specific planting time is slightly different, generally around mid-July, the local folk have, the head of the radish, the second cabbage said, the autumn cabbage can not be planted, according to the date of the solar calendar to plant, the specific planting of varieties, and the climate of the land is also related, the Northeast region July 20 to 23 planting is the best, planting too early, love to get sick.

In general, the best planting time for autumn cabbage is 3-5 days before and after the beginning of autumn. In addition, disease-resistant late-maturing varieties with long growth period can be sown early, and medium-maturing varieties with short growth period can be sown a few days late.

According to the production situation in recent years, the high temperature in the early stage is not conducive to the growth of seedlings, and the early harvest period is not conducive to storage. If the varieties selected are not with a long growth period, it is best to plant them a few days later after the beginning of autumn, combined with high ridge cultivation, which can significantly reduce the disease.

The best time to plant autumn cabbage in the Yangtze River Delta is in mid-September, because the seasonality and regionality of vegetables in this region are strong, and Zhejiang can be sown in mid-September at the latest, and early and medium-ripening varieties are selected.

The sowing period in North China and Beijing-Tianjin is about August 3 and 8, and it is mature and ready for market in early November.

Autumn cabbage is generally sown 3-5 days before and after the beginning of autumn, and high temperature years can be postponed to mid-August. Late-maturing varieties with disease resistance and long growth period can be sown early, and medium-maturing varieties with short growth period can be sown a few days late.

Choose the best varieties. There are many varieties of Chinese cabbage, which can be divided into three basic ecological types: straight type, original head type and oval type, but due to the reasons of the growing season, the middle and late maturing varieties that are resistant to disease, cold-resistant, high-yield and storable must be selected in the selection.

Preparation before sowing. Chinese cabbage cannot be cropped in succession or rotated with other cruciferous vegetables, which is one of the important measures to prevent pests and diseases. 5-10 cm deep ditch, first watering along the ditch, after water penetration, the seeds are evenly sprinkled in the ditch, and sprinkled with centimeter thick fine soil, the amount of seeds per mu is about kilograms, and the Chinese cabbage is unearthed, take measures to water water frequently, keep the ground moist and reduce the surface temperature.

In the absence of rain, water once on the day of sowing or the next day to ensure that the ridge surface is soaked, and water the second time on the third day of sowing to cause most of the young shoots to emerge.
