When is the best time to harvest Chinese cabbage?

Generally speaking, it is better to harvest Chinese cabbage in autumn, and it is better to harvest it in mid to late November every year, when the nutritional value of Chinese cabbage is relatively high and more lush.

In the north, it is best to harvest at a time near the solar term of light snow, so that the yield will be relatively high, and then the nutritional value will be relatively high, and at the same time, the Chinese cabbage at this time will also grow very lushly.

I think it's usually in the fall, and it's just the right time when the weather is cold and the weather is good, and it's easy to preserve, and the cabbage grows better.

The timing of the Chinese cabbage harvest is very important. If it is harvested too early, its yield will be greatly reduced, and the quality of its nutrients will be very low.

I think it's okay to harvest it before it freezes, because at that time the cabbage is strong enough to hold it.

Chinese cabbage in the north is not planted for a long time, and it can be harvested in mid to late October in autumn.

Northern cabbage is planted in the spring and method.

1. Planting time.

The north is suitable for planting Chinese cabbage in autumn, early and mid-August varieties can be planted, mid-late varieties can be planted from late August to early September, and late-maturing varieties can be planted in late August.

2. Planting method.

1) Soil preparation and fertilization.

Cabbage is generally suitable for planting in sandy loam plots with loose and fertile soil and rich organic matter content, and the front crop should not be cruciferous.

Crop. 1 week before sowing, deep plough the soil and rake finely, then level the furrow, dig the furrow to facilitate drainage and irrigation work, and apply sufficient decomposed manure or trim fertilizer in the furrow.

2) Sowing seedlings.

Select the seeds with strong cold resistance and stress resistance, no disease for sowing, sowing can be used in strip sowing, hole sowing, machine sowing these three ways, each sowing hole can be put into 3-4 seeds, the amount of seeds per mu is about kilograms. After sowing, it is necessary to water 1 time in time to keep the soil moist.

3) Colonization.

After the seedlings enter the 5-6 leaf stage, they begin to transplant and plant, and the transplanting work can be carried out in the afternoon of sunny weather, and the light is stronger at noon, so as to improve the survival rate of seedlings.

The transplanting density can be determined according to the soil, Chinese cabbage varieties and other conditions, and the transplanting plant spacing is generally about 20 cm, and it is necessary to water in time after transplanting, so as to facilitate the slow seedling.

4) Scientific management.

1) At the rosette stage of cabbage, nitrogen fertilizer was applied once and ammonia fertilizer was applied. At the balling stage of cabbage, ammonia fertilizer is mainly applied and nitrogen fertilizer is supplemented.

2) If you are affected by noctuidae and aphids during planting.

and other insect pests, you can spray low-toxicity drugs.

3) If weeds appear in the field, they can be pulled out manually, and herbicides should not be used as much as possible.

4) If anthrax occurs.

At the beginning of the disease, 40% polysulfur suspension 600 times or 50% carbendazim can be sprayed.

500 times liquid, or 80% anthrax Fumei 800 times liquid, or polyoxymycin 1000 times liquid, spray 1 time every 7-10 days, 2-3 times in a row.

The northern Chinese cabbage harvest time is generally from late October to early November.

Cabbage in the north is generally harvested in late October and early November before the beginning of winter.

The cabbage in the north is generally harvested at the end of October, and the frost is downgraded and lost.

Winter is the best time to harvest Chinese cabbage.

When the leaves of Chinese cabbage grow to the peak, and the ball is tight but not loose, it is generally the period when the yield of Chinese cabbage is the highest.

There are at least three kinds of Chinese cabbage, one is 90 days, and it takes nearly 3 months after sowing seeds to be harvested after wrapping; the other is 60 days, which can be harvested with a little heart; There is also a 50-day one, which is the fastest harvest, and it can be marketed in less than 50 days after sowing.

Chinese cabbage should be harvested late at the right time, but when the temperature is below minus 2 degrees, it will be damaged by frost. Therefore, it is necessary to harvest before the first frost damage.

Cabbage is resistant to low temperature, very resistant to low temperature, after the temperature reaches -3, if the temperature can gradually rise, it can also resume growth, but if it reaches -8, the temperature continues to drop to about -11, it can not resume normal growth and suffer from frost damage.

When is the northern cabbage planted properly:

The time for planting cabbage in the north is generally autumn, mainly concentrated in August, and not later than late September, otherwise it is easy to suffer from frost damage and affect the yield. The specific planting time is related to the varieties of cabbage, and the medium-ripening varieties with a short growth period can be sown a few days late, and the late-maturing varieties with disease resistance and long growth period can be sown early.

1. Early-maturing varieties: generally planted in early August.

2. Medium-ripening varieties: generally planted from late August to early September.

3. Late-maturing varieties: generally planted in late August.

Cabbage is suitable for planting in loam, sandy loam and black loess with fertilizer and water retention and rich in organic matter, not suitable for planting in sandy soil that is easy to leak water and feces, and not suitable for planting in clay soil with poor drainage, and the soil moisture content should be controlled between 40-80% during the whole growth period.

Chinese cabbage can be divided into spring Chinese cabbage, summer Chinese cabbage, and autumn Chinese cabbage according to the season.

Spring Chinese cabbage is planted from late March to early April, and early-maturing varieties with short growth period, low temperature tolerance, and good bulb formation are selected, and leaf bulbs are formed before the high temperature in summer.

Summer Chinese cabbage is planted from mid-May to early July, and the summer cabbage planting time is relatively free, and the harvest is in the off-season of vegetables, which is high, but high temperature and rain are not conducive to the formation of leaf balls, and there are many pests and diseases.

Autumn Chinese cabbage is planted 3-5 days before and after the beginning of autumn, and can be sown a few days early or a few days later according to the actual local weather conditions, 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. The exact timing of sowing varies across the country

1. The autumn Chinese cabbage sowing time in northern, northwest and northern North China is mid to late July.

2. The sowing time in the southern part of Northeast China, the central and southern parts of North China and the Huanghuai region is in early August.

3. Southern Fujian, Liangguang, Yunnan, Hainan and other provinces should sow overwintering Chinese cabbage in mid-September or early October.

Cabbage can be planted in July and August, and can be planted in November at the latest until next year.

Answer: The latest time to plant cabbage depends on the weather in the region. If it is in a cold region in the north, the planting time can be selected in early August, otherwise the temperature will be low in the later stage, and the germination of cabbage will be hindered and it will be easy to be frostbitten. If it is in the warm southern region, the planting time can be around September, when the climate is suitable and the cabbage will grow faster.

Spring cabbage planting time.

Spring cabbage refers to the cabbage sown in spring, which is an early-maturing or medium-early maturing type of crop with weak short-light light, which is cultivated in various parts of China, and the timely sowing of cabbage is generally broadcast in late March to early April.

Summer cabbage planting time.

Summer cabbage is between summer and autumn to market Chinese cabbage, at this time it is the off-season of vegetables, the economic benefits are considerable, summer cabbage is generally sown in mid-May to early July.

Autumn cabbage planting time.

Under normal circumstances, the autumn cabbage planting time is best sown 3-5 days before and after the beginning of autumn, but according to the actual weather conditions, the autumn cabbage planting time can be appropriately postponed or advanced, in addition, the disease-resistant, long-growing late-maturing varieties can be appropriately sown early, and the medium-ripening varieties with a short growth period can be appropriately sown a few days late.

The harvest time of different varieties of cabbage will also be different, if it is summer cabbage, it is best to harvest it in July and August, and if it is autumn cabbage, it is best around mid-November.

Summer cabbage is a more suitable environment for the growth of cabbage whether it is sown or harvested. The purpose of summer cabbage cultivation is mainly to meet market demand, and it is generally planted in May and June and harvested in July and August.

Autumn cabbage has a short growing period and sets balls quickly, but its harvest time is relatively strict. If the harvested cabbage needs to be stored in winter, it can be done in light snow.

Harvesting takes place around the time of the solar term, and the environment is better in mid-November.

Harvesting at this time will prolong the growth period of cabbage, and harvesting in late November can prevent frost damage to cabbage, so it is more suitable. However, the temperature at the time of harvest should ensure that all harvests are above minus 3 degrees Celsius to avoid frost damage.

Precautions for cabbage harvesting

If you want cabbage to have a high profit, you can harvest it when the cabbage leaf balls are not completely compacted and go on the market. For mid-to-late varieties of cabbage, the longer the growth period, the more mature the leaf bulbs will be, and the yield will also increase.

However, it should be noted that cabbage can only tolerate light frost, and if it encounters sub-zero temperatures, it will be prone to frost damage.

Chinese cabbage is usually planted in autumn, generally sown 3 5 days before and after the beginning of autumn, but also in late March to early April in spring or mid-May to early July in autumn, the best harvest time for Chinese cabbage is generally around mid-November, the specific time also changes according to its local climate change, but in some places Chinese cabbage can be harvested in September.

Chinese cabbage planting time.

Chinese cabbage is usually planted in autumn, generally sown in 3 5 days before and after the beginning of autumn, wide hail can also be appropriately delayed or advanced according to the actual weather conditions, and Chinese cabbage can also be sown in late March to early April in spring, or sowing in mid-May to early July in autumn.

Chinese cabbage harvest time.

The best time to harvest Chinese cabbage is generally around mid-November, depending on the local climate change, but in some places it can be harvested in September, and the longer the mid-to-late varieties grow, the better they will taste and the higher the yield.

Key points of high-yield planting of Chinese cabbage.

1. Tidy up the soil

Chinese cabbage can be grown in both the north and south, has a wide adaptability to the soil, and can grow in many soils, in order to promote growth, it is best to provide rich organic matter, loose and fertile sandy loam soil, prepare the land in advance, and apply well-rotted organic fertilizer.

2. Prepare the seeds

Before sowing Chinese cabbage, seeds should be selected, requiring disease-free, stress-resistant, cold-tolerant seeds, dried for 1-2 days before sowing, prepared with warm water of about 55 degrees Celsius, soaked in seeds for about 15 minutes, and sterilized and disinfected with chlorothalonil clean seeds.

3. Carry out sowing

The sowing methods used in Chinese cabbage are strip sowing, prudent sail hole sowing, machine sowing, commonly used to sow Chinese cabbage seeds, pay attention to the planting density, cover with fine soil after sowing, and keep it moist with watering.

4. Field management

When Chinese cabbage grows 4 to 5 true leaves, do a good job of thinning seedlings, replenishing seedlings, and cleaning weeds, and transplant and colonize when the seedlings grow to 5 to 6 true leaves.

Cabbage is more common in North China in China, and it is generally harvested in November every year, but the specific time is still determined according to the climate and environment at that time, and in some areas it can be harvested in September every year. In general, the longer the mid-to-late varieties grow, the higher the yield and the better the taste.

Cabbage harvest time.

Cabbage is generally harvested in November every year, but the specific time is still determined by the climate and environment at that time, in some areas it can be harvested in September every year, under normal circumstances, the longer the growth time of the mid-late varieties, the higher the yield, and the taste is also good.

Cabbage cavity with origin.

Cabbage likes a cool growth environment, it is more common in North China in China, the main production area is in the south of the Yangtze River, it is more common in Hebei, Shandong, Shanxi and other places, and the adaptability of cabbage is relatively strong, so in addition to winter, other seasons can be planted, so there is basically a harvest throughout the year.

Cabbage planting time and points.

Cabbage is planted in July and August every year, and it prefers a cold climate, so it is not suitable for planting in hot weather, but it is also necessary to avoid too cold season.

2. Deep ploughing of the soil:Before planting, cabbage needs to be deeply turned into the soil, and some stones, weeds and plant rhizomes need to be removed, which can increase soil porosity and fertility.

3. Planting method:After the soil is treated, the cabbage can be planted, and it is necessary to use relatively full seeds, and the seeds need to be disinfected before planting, and they need to be watered once after sowing.
