When is the best time to grow bok choy? What season is the best season for bok choy?

Chinese cabbage can be divided into spring cabbage, summer cabbage, autumn and winter cabbage according to the difference in planting time. For which kind of cabbage has a stronger taste, I think that the taste of cabbage planted in autumn and winter is stronger, because there are as few cabbage pests and diseases as possible in winter, and many vegetables and fruits in winter belong to off-season vegetables and fruits, the taste is not very good, and at this moment you will feel that the cabbage in winter is particularly delicious. Autumn and winter cabbage is generally grown from September to December in South China, from early August to October in the Zhuhai region, and in Northeast China.

Generally, it is gradually planted up and down the cold dew, left and right.

Chinese cabbage grown in season is the most delicious. Mainly because Chinese cabbage also has its own growth and development regularity, and also has its most suitable growth cycle time, in which the natural environment.

Temperature is the most critical element, which determines when Chinese cabbage should be planted, and under which temperature standards will sprout, grow seedlings, set balls, cor and obtain. The average monthly temperature suitable for Chinese cabbage planting is in the middle of 15 18, the maximum temperature is 21 24, and the minimum temperature is around 7.

In general, the seeds sown in the middle of 20 25 in the natural environment germinate quickly and the seedlings are strong, and the germination is rapid in the middle of 26 30, but the weak seedlings after the seedlings are weak and harmful to the growth in the middle and late stages, and the seedlings produce poor growth after the premise of more than 30. The natural environment temperature in the middle of 22 25 is a suitable prerequisite for the growth of seedlings, and the temperature within 30 has little effect on the growth of seedlings. Natural ambient temperature 16 22 It is most suitable for the growth of cabbage in the rosette stage, if the temperature is too high.

If the temperature is too low, it will lead to stunted growth.

Cabbage belongs to the cruciferous family.

Green plants are grown in most places in China. Cabbage likes to grow in wet and cold climates, and the most suitable growing temperature is between 15 degrees and 22 degrees, beyond which the temperature will lead to poor growth of cabbage. At the beginning of autumn, the temperature in most areas has dropped to less than 25 degrees Celsius, which is very beneficial to the growth of cabbage.

From the growth habit of cabbage, it can be seen that it is in dog days.

Growing cabbage is very correct, only if it grows well, Chinese cabbage can be delicious.

I think that planting Chinese cabbage in the spring and then harvesting it in late autumn is the best way to grow Chinese cabbage.

In general, autumn is the best time to grow Chinese cabbage. Chinese cabbage is the best in winter.

I think Chinese cabbage grown in early summer is more delicious. It is best to plant it in early summer and harvest it in late autumn.

Early-maturing varieties are generally sown in early to mid-August, and some are sown as early as late July. Medium-ripening varieties can be sown in late August to early September. Late-maturing varieties should be sown in late August.

Timely sowing is the key to the bumper yield of Chinese cabbage, and the temperature is too high in the early stage of sowing, which is easy to be harmed by diseases and insects. In the later stage, it will also have premature aging, and it is not necessary to increase production. If the sowing is too late, the growth period is short, and the effective accumulated temperature is insufficient, and the yield will be reduced due to insufficient "irrigation".

After experiments, the timely sowing dates of various Chinese cabbages in eastern Hebei are as follows (other regions can refer to the climate delay or embankment in eastern Hebei region): the timely sowing dates of green walnut and Yutian Baojian Chinese cabbage are from August 5 to 7; Walnut cabbage should be from August 6 to 9; Green baotou cabbage should be on August 2-4.

Yes, the timing of the sowing period mentioned above is not fixed, and in hot years, the sowing date can be postponed by a day or two. In cooler years, you can sow a day or two earlier, which refers to the direct seeding of cabbage, if you plant transplanted cabbage, the sowing date should be two to three days earlier.

Pest control

Principle: prevention first, comprehensive prevention and control, give priority to agricultural control, physical control, biological control, and chemical control. Pesticide application strictly implements the provisions of NY T1276-2007 and all parts of GB).

Agricultural prevention and control selects excellent varieties, cultivates strong seedlings, sows seeds in a timely manner, rotates crop stubble, strengthens management, and cleans the countryside. [5]

Physical control

Yellow sticky insect boards are used to trap and kill aphids, whiteflies and other pests.

Sweet and sour liquid booby-trapping: The sweet and sour liquid is prepared with 3 parts of sugar, 3 parts of vinegar, 1 part of high liquor, 10 parts of water, and 90% of crystal trichlorfon, mix evenly and put it into a large bowl, place 1 per 80 square meters, cover it during the day, open it at night, and change the sweet and sour solution for 1 time in 10-15 days. [5]

Biological control: release of natural enemies, such as predatory mites, parasitic wasps, etc.; the use of biopesticides such as Bacillus thuringiensis, avermectin, etc.; Apply biological fertilizer inch,Chemical control

Aphids and whiteflies should be alternately sprayed with 10% imidacloprid wettable powder 1000-1500 times, or 10% acetamiprid 1000-1500 times, sprayed 2-3 times, paying attention to the back of the leaves. Brassica and Spodoptera exigua were sprayed alternately with cypermethrin 2000 times or cyhalothrin 3000 times before the 3rd instar.

For downy mildew, 1500 times of 25% di-alkynylamide suspension, or 600-800 times of 72% frost urea manganese-zinc wettable powder, used in rotation, sprayed once in 7-10 days, and continuously controlled 2-3 times. Soft rot is sprayed with 4000 times of 72% agricultural streptomycin sulfate wettable powder, or 1000 times of 3% Zhongshengmycin wettable powder.

Due to the different regional climates, the planting time of autumn cabbage is also different, but under normal circumstances, it is a good time to plant autumn cabbage 3-5 days before and after the beginning of autumn.

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 weather conditions this year, the autumn cabbage planting time this year can be postponed to mid-August. 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.

The planting time of Chinese cabbage varies greatly depending on the region and the season. Autumn Chinese cabbage sowing time in the north. 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 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.

Under normal circumstances, the planting time of autumn cabbage is best sown 3-5 days before and after the beginning of autumn, and the high temperature year 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.

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 sowing date: generally in late March and early April.

Suitable sowing date for summer cabbage: generally sowing in mid-May and early July.

Autumn cabbage sowing date: generally sowing 3 to 5 days before and after the beginning of autumn, but also according to the actual weather conditions, can be appropriately postponed or advanced.

Cabbage prefers a cool climate, with an average temperature of 18-20 and sunny conditions to grow best. -2 -3 can safely overwinter. Above 25, the heat is weak and susceptible to viral diseases, and only a few heat-tolerant varieties can be cultivated in the summer.

Cabbage planting season and time.

Chinese cabbage is divided into three planting stages: spring, summer, and autumn. The sowing time of spring Chinese cabbage is from late March to early April, summer Chinese cabbage is from mid-May to early July, autumn Chinese cabbage is about 3-5 days after the beginning of autumn, the best time to plant Chinese cabbage in the open field is from August to September, and greenhouse Chinese cabbage is planted in mid-February in spring.

Cabbage harvest season.

Spring cabbage is harvested in the spring of the second year; In summer, cabbage can be harvested continuously; Autumn and winter cabbage is harvested in stages in southern China until February of the following year, while in the Jianghuai region, it is harvested before freezing.

Cabbage planting steps and methods.

1.Seed selection: select the variety of seeds according to the planting area to ensure the shelf life of cabbage seeds; 2.

Soil: Choose a piece of loose and fertile soil with good air permeability for planting, turn the soil deeper, and then apply a certain amount of base fertilizer; 3.Sowing:

The seeds are germinated by the trembling beam before sowing the acacia seeds, and after germination, they are sprinkled into the soil, and then covered with a thin layer of soil.

Sowing in March and April in the spring, or August and September in the winter.

Chinese cabbage growth cycle

The growth cycle of Chinese cabbage is about 55 days, which can be divided into two kinds according to the development stage: vegetative growth period and reproductive growth period, among which, the vegetative growth period is divided into germination stage, seedling stage and rosette stage; The reproductive growth period can also be divided into two types: the pregnancy bud period and the flowering and fruiting period, and each growth period is crucial.

Methods and steps for growing Chinese cabbage

1. Sowing

The sowing of Chinese cabbage is very important, about a week before sowing Chinese cabbage, we have to plough the land, because the need for environmental conditions is the key to harvesting, and then spread the seeds evenly on the soil surface, covering with a layer of fine soil.

2. Seedlings

Chinese cabbage should be planted in fertile and soft soil, the seedling period is about 20 to 25 days, when the temperature is relatively low, the growth rate of seedlings will be slow, and it takes about a month and a half to emerge.

Chinese cabbage planting should be planted within 10 days after August 15, so that it can be more conducive to the monitoring and growth of Chinese cabbage. However, there are also Chinese cabbages planted out of season, and due to environmental and other factors, their taste is also incomparable.

Chinese cabbage is also a very common vegetable in rural areas, in the countryside, villagers will grow some cabbage more or less every year, most of them are not for sale, usually to satisfy their own family food.

If you want to say when the Chinese cabbage planted is the best to eat, according to the growth law of Chinese cabbage, the Chinese cabbage planted in season is the best.

Today's vegetable cultivation is not as good as it used to beNo matter what the season is, as long as scientific planting management measures are taken, even in winter, vegetables can be grown in greenhouses

However, the same vegetable species, different planting and management methods, the taste is indeed completely different, so there is nothing wrong with saying that Chinese cabbage is the most delicious when planted in season. So when should Chinese cabbage be planted in season?

It may be different depending on the climatic conditions of each region, and the time period of cultivation may also be different. There is a saying in the seasonal time of Chinese cabbage planting in my hometown: "Toufu radish, Erfu mustard, and Sanfu can grow cabbage with jujubes."

It means that,The first volt is the time to plant radish, the mustard greens should be planted in the second volt, and the Chinese cabbage should be planted during the third dog period

This year's dog days started on August 15, that is to say, Chinese cabbage planting should be planted within 10 days after August 15, so as to be more conducive to the growth of Chinese cabbage. The dog days have already entered autumn, and after the dog days, the temperature will gradually drop.

For the northern season, the best time to grow cabbage is from late July to early August. Friends in the south can try to sow cabbage in spring, summer and autumn.

Chinese cabbage is actually a relatively hardy plant, and its growth process is basically completed in autumn, even in winter, when the weather is not too cold.

Some villagers let the Chinese cabbage grow in the yard, even a few degrees below zero, and the Chinese cabbage is also delicious.

This is because Chinese cabbage has its own growth and development law, which can allow it to grow naturally, and it can grow naturally within a sufficient growth cycle, subject to environmental changes and suitable temperatures.

Chinese cabbage absorbs sufficient nutrients and can grow benignly, so the Chinese cabbage after ripening and harvesting is indeed very delicious.

Chinese cabbage can be eaten raw or fried, raw sweet and crisp, cooked soft and fragrant, this is the Chinese cabbage grown and grown in the natural environment.

However, there are also Chinese cabbages planted out of season, and due to environmental and other factors, their taste is also incomparable.
