When is kale planted When is kale planted

"Kale is a cold-tolerant plant that prefers to grow in warm environments, and is usually sown in February to March every year, with the best time to sow in the afternoon, when the temperature is suitable for kale growth.

Kale is an annual herb of the cruciferous family.

The fat and tender flower tombs and young leaves are used for eating, and the quality is crisp and sweet. It is produced in Guangdong, China and other places.

Because the stem is thick and erect, the cell tissue is compact, the water content is less, and the epidermis has a layer of wax, so it is refreshing but not hard, brittle but not tough. Su Dongpo also wrote poems to praise it"Kale is like Juncao, and the crisp teeth and cheeks are ringing"。

February and March. Kale is one of the special vegetables in our country, which is usually sown in February and March every year, with a fast growth rate and can mature in June and October, and the medium and late maturing varieties can also be planted around November every year.

Kale is suitable for planting in several months, kale is one of the special vegetables in our country, usually sown in February and March every year, the growth rate is fast, it can mature in June and October, and the medium and late maturing varieties can also be planted around November every year.

Kale planting method land preparation and fertilization kale planting should choose fertile, good water and fertilizer retention soil, and then apply an appropriate amount of base fertilizer per mu, turn into the soil and mix evenly, the soil needs to be cultivated and leveled, and finally leveled to make furrows.

The best time to sow kale is from April to October every year.

Kale planting should be selected according to the climatic conditions of cultivation, and it can be planted in the open field in April and October. Water thoroughly before sowing and start sowing when the water has completely penetrated into the soil.

Kale likes mild climatic conditions, the temperature can grow well in the range of 10-30, can tolerate short-term -2 low temperature and light frost, avoid high temperature and hot weather, and is suitable for 15-25 during the whole growth period. The suitable temperature of the germination period is 25-30, and the germination is slow below 20.

The suitable temperature for seedling growth is about 20, and it can grow slowly under the conditions of high temperature above 28 or lower temperature below l0. However, it affects the normal differentiation of flower buds, and the appropriate temperature of flower bud differentiation is L0-20. The leaf growth period should be about 20, and the formation period of rapeseed should be about 15, and the temperature difference between day and night is required to be large, so as to facilitate the growth and formation of rapeseed.

Kale planting on light requirements Kale is a long-day plant, light does not tolerate shade, good light conditions, sufficient light, strong plant growth, thick stems and leaves, good development of rapeseed} If the light is insufficient, the light is weak, it will inhibit growth, resulting in weak growth, easy to be infected with diseases, poor quality of rapeseed, and low yield.

Yes, kale can be grown all year round.

Cultivation method: 1. Seedling sowing.

Chinese kale. It can be transplanted by direct seeding or seedling rearing. Kale seedlings should be selected loose and fertile and easy to drain and irrigate sandy loam or loam, during the planting period to keep the soil moist, can also be appropriately applied some thin fertilizer to promote the growth of seedlings.

The sowing amount is appropriate, pay attention to the seedlings, and avoid too dense to cause the seedlings to be thin and weak.

2. Field management.

The growth of kale is slow in the early stage, and weeds are easy to grow between the rows, so it is necessary to carry out weeding in time. In daily management, it is necessary to water the vegetable moss in time according to the temperature and humidity conditions.

During the formation and harvest periods, it is necessary to increase the frequency of watering and keep the soil moist frequently.

Base fertilizer and top dressing are equally important, top dressing with water, generally 3 4 days after the seedling is slowed down to apply a small amount of nitrogen fertilizer or sea meal fertile water-soluble fertilizer, and the appropriate fast-acting fertilizer or human feces are applied when the buds are pumped. After the main moss is harvested, to promote the growth of the side moss, top dressing should be reapplied 2 3 times.

3. Pest control.

Compared with other vegetables, the diseases and pests of kale are still relatively few, but black rot is prone to occur in high temperature and high humidity weather, which can seriously lead to plant death, and needs to be prevented and controlled in time.

Prevention and control methods: 1) Avoid cruciferous flowers.

vegetable continuous cropping; 2) If diseased plants are found in the field, they should be uprooted in time;

3) As soon as you find that you are sick, you can spray chlorothalonil immediately.

Dichlorpheazim, etc.

Fourth, harvest at the right time.

The harvest time of kale is generally selected in the morning on a sunny day, and the main flower sprout is harvested by cutting off the six leaves at the base of the plant. The harvest of the lateral flower sprout is cut at the base of the sprout at the 2 leaves. Be careful that the incision must be tilted so that the stagnant water does not rot.

Late-maturing kale. - More than 75 days from sowing to harvesting, strong winter, need a certain low temperature to sprout, suitable for winter and spring cultivation. The representative varieties are:

Late-flowered kale。The main sprout is 28 cm long, weighs 120 grams, has a medium branching capacity, and the flesh is tender and crispy.

Copper-shelled leaf kale。The plant grows vigorously, the leaves are relatively thin, the wax powder is relatively small, and the weight of the plant moss after harvest is more than 100 grams.

How to grow kale

When planting kale, it is necessary to retain water and fertilize it, and choose loose soil. With sufficient fertilizer moisture, the seeds of kale will germinate faster. Kale can be seeded or transplanted.

When sowing seeds, dig holes in advance, the distance between seedlings and seedlings is the most suitable to control at twenty or thirty centimeters, and put 3-5 seeds in each hole, which can effectively ensure the survival rate. Too much will prevent each seed from growing properly.

Time selection: It can be carried out all year round, cultivated in open field and protected land, and cultivated in the planting area from September to March of the following year.

1.Spring. 1) Medium-ripening varieties can be used for improved impotence.

Seedlings are sown in the greenhouse from late November to early January of the following year, and the seedlings are 35 days old. Planting is from early January to early February. About 70 days after planting, the harvest will be continuous for 40-50 days, that is, from the first to the middle of March to the second half of May.

2) Medium-ripe varieties are used in plastic greenhouses. Greenhouse seedlings are raised in mid-to-late January, planted in deficit from late February to March, and harvested from April to July.

3) Heat-tolerant and early-maturing varieties are used in spring dew land, greenhouse seedlings are raised from the first sentence to the next sentence in February, planted in the middle of March to the first sentence of April, and can be harvested more than 60 days after planting, and the harvest period is extended for 35-45 days, and harvested in the middle of July in May.

2.Summertime. In summer, plain areas can be cultivated with plastic trellis covered with shade nets. It is more suitable for open field cultivation in mountainous areas. Early-maturing heat-tolerant varieties are used, seedlings are raised from early to late May, planted from early to late June, and harvested from mid-July to late September.

3.Autumn. 1) Medium-ripening varieties were used in autumn dew land, improved Yangqi seedlings were raised in early to mid-June, planted in early and mid-July, and harvested from mid-to-late September to early November.

2) Medium-ripe seeds are used in plastic greenhouses, and seedlings are improved from mid-June to early July, planted from mid-July to early May, and harvested from late September to mid-November.

3) Medium-ripe varieties were used for improved yangqi, seedlings were raised from early to late July, planted from early to late August, and harvested from early October to late November.

4.Winter. Solar greenhouse, using cold-tolerant late-maturing varieties.

From early August to early to mid-October, seedlings are raised, sown in the open field in the early stage, and sowing in the later stage of improved and rapidly destroyed Shenyang furrow. Planting is from early to late September, or live broadcast from mid to late November, and harvesting can be from mid to late November to early March.

1. Kale has poor cold tolerance and likes to grow in a warm environment. Therefore, it is mostly sown in the spring, specifically in February and March, and after planting, it will mature between June and October.

2. When sowing, the soil should be turned deep and disinfected. Pay attention to the density of planting, not too dense and not too thin. After planting, water the soil appropriately to ensure that the nutrients are sufficient, and the travel finger should bask in the sun more, so that the growth in the later stage will be better.

<> kale is one of China's special vegetables, also known as kale, etc., is an annual herbaceous plant of the cruciferous family, Brassica is an annual herbaceous plant, the cabbage moss is tender, crisp, sweet, delicious, with fat and tender flowers and young leaves for eating, the cultivation history in our country is very long. Let's take a look at how and when kale is grown

1. Planting time.

Planting in the Beijing area can basically be anniversary**. Early-maturing varieties such as willow-leaved early kale are cultivated in the open field to ensure a ** in June and October. From September to March of the second year, sowing can be selected for medium flowering, medium and late mustard and other medium and late varieties for cultivation in protected areas, to ensure that from November to May of the second year, it should be noted that 7 September is the high temperature and rainy season in Beijing, and it is advisable to plant in a cool place.

2. Planting method.

1. Land preparation and fertilization: kale planting is selected to retain fertilizer and water, fine land preparation, 3000 4000 kg of rotted pig manure and compost are applied per mu, and 25 kg of superphosphate are applied to the soil. Furrows are generally made flat, but small high furrows should be made for summer cultivation.

2. Planting method: kale cultivation in the open field should be carried out in the afternoon, and cultivation in the protected area should be carried out in the morning. After the planting date is determined, the seedbed should be watered thoroughly in the afternoon before planting so that the seedlings can be dug the next day.

On the day of planting, the seedlings will be dug and then transported to the planting plot, and the seedlings will be planted according to a certain row spacing.

3. Planting density: the row spacing of early-maturing seeds is 25 cm 20 cm, the row spacing of medium-maturing seeds is 30 cm 22 cm, and the spacing of late-maturing seeds is 30 cm and 30 cm. The seedlings should not be planted deep, and the soil surface of the seedling mound and the furrow surface should be planted flat or slightly lower by 1 cm.

Once the seedlings are planted, they are watered to restore their growth.

4. Watering and fertilization: according to the temperature and humidity at that time, water the seedlings in a timely manner, and properly control the watering during the growth period of leaf clusters after the seedlings, and enter the formation period and harvest period of vegetable moss, increase the number of watering, and often keep the soil moist. Base fertilizer and top dressing are equally important, top dressing with water, generally 3 4 days after the seedling to apply a small amount of nitrogen fertilizer or chicken manure dilute, now bud moss when the appropriate fast-acting fertilizer or human feces.

After the main moss is harvested, to promote the growth of the side moss, top dressing should be reapplied 2 3 times.

5. Cultivating soil: Kale grows slowly in the early stage, and weeds are easy to grow between the rows, so it is necessary to carry out weeding in time. With the growth of the plant, the stem from fine to thick, the base is thinner, the upper part is larger, the formation is top-heavy, to combine the cultivation of Zen debate for soil cultivation, fertilization, it is best to apply 1000 2000 kg of organic fertilizer per mu.

6. Pest control: Kale has fewer diseases, and black rot is more common, which is a bacterial disease, which is easy to occur at high temperature and high humidity. The prevention and control method is to select disease-resistant varieties, avoid continuous cropping with cruciferous vegetables, find that the diseased seedlings are pulled out in time, and spray fungicides such as chlorothalonil when the disease spots are found at the beginning.

In addition, when the temperature is low and the humidity is high, the leaves, stems and peduncles of greenhouse cultivation are prone to downy mildew.

7. Timely harvesting: When the kale flower sprout grows to the height of the top of the leaf or close to the height (commonly known as the mouth flower), it is a suitable harvest period, and the harvest height is 15 25 cm. In order to maintain good commerciality, it is advisable to harvest early in the morning and organize the packaging.
