Can kale be grown in the north, and when is kale grown

First of all, my personal opinion: this year's temperature is relatively low, resulting in a decrease in the germination rate of tea trees, affecting the yield of tea trees, and it is indeed very annoying, so improving the germination rate of tea is fundamental, in order to ensure that the branches are strong and the fertility is sufficient, use some foliar fertilizers containing plant growth regulators (such as: brassinolide (such as Yunda-120 and Jinyunda-120)), spray several times, should be good for promoting budding.

There are also some manufacturers such as Sichuan Guoguang's tea diluted beauty, you can also, it is recommended that you go to the local plant protection station to consult, and buy some to try, and then use it in a large area.

It seems that it cannot be cultivated on a large scale.

Tea trees grow on acidic soils, northern soils. Water is alkaline and not conducive to growth, but it can be planted on a small scale, and the economic benefits of large-scale planting will not be too good.

Dou Meishi, Jin Qi Yifei, and the coupons went to see the three Ruixi.

Kale is one of the special vegetables in our country, and it is usually sown in February and March every year

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 sowing in autumn or early spring, and the best sowing effect is in mid to early March, when the temperature has risen to more than 15 degrees Celsius, which is conducive to its seed germination and plant growth, and can complete the seedling development before the rainy season, and quickly grow into a mature body.

Kale cultivation method.

1. Soil preparation and fertilization.

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

2. Handle tubers.

Kale can be sown by seedling transplanting, and the southern region can also be seeded in the open field, and the land for seedlings is best sandy loam, and the front stubble of this planting land can not be cruciferous vegetables.

Points to note when planting kale.

1. After the kale is planted, it is necessary to properly control the watering during the leaf cluster growth period, and increase the number of watering when entering the harvest period, and it is best to keep the soil slightly moist.

2. Kale will grow slowly in the early stage and is prone to weeds, so it is necessary to carry out weeding in time, and at the same time, it is necessary to combine soil cultivation and fertilization, and the fertilizer is best based on organic fertilizer.

Kale can be planted in February to March every spring, the healthy seeds can be sown in the soil, after planting, the kale should be watered once a day, and after the seeds germinate, nitrogen fertilizer and urea need to be applied to it to promote the growth of seedlings, and provide full sunshine for the kale, so that the plant can grow vigorously.

1. Sowing time

Planting kale can be carried out in the spring, when the temperature gradually rises, which is more suitable for the germination and growth of seeds, but at this time it is suitable for planting early-maturing varieties, and if you want to plant late-maturing varieties, you can sow them in July and August every autumn.

2. Sow seeds and raise seedlings

Sowing kale should use full seeds, and soak and disinfect them, wait for the seeds to expose the white part, you can take them out, drain the water, and then sow them in a loose and breathable, sunny and ventilated field, after the seedlings grow, the seedlings with thin growth should be removed, and the planting density should be reduced.

3. Watering and fertilizing

Kale has a certain demand for water and fertilizer, in the process of breeding, it is necessary to apply rotten farmhouse fertilizer to it, improve the growth rate of the plant, and water the kale every other week to keep the soil slightly wet, when the temperature is too high, the evaporation of water is accelerated, at this time it is necessary to spray water mist to kale to improve the environmental humidity.

4. Provide light

Kale is suitable for growing in a sunny environment, in the case of insufficient light, its growth will deteriorate, it is best to put the kale in the sunny place when breeding, to provide full sunshine for it, but when the light is too strong in summer, it is necessary to pull a shade net for the kale, so as not to sunburn the leaves.

1. Planting method: Kale is planted in fertile soil mixed with superphosphate and covered with a thin layer of soil. 2. Watering:

Water every 3 days at the seedling stage of kale, control the amount of watering during the growing period, and increase the water supply after the kale enters the rapeseed stage. 3. Loosening the soil and pulling weeds: When cultivating kale, regularly cultivate and pull weeds to avoid weeds and plants competing for nutrients.

1. Planting method

Kale is suitable for growing in fertile sandy loam soil, when planting kale, you need to apply superphosphate and well-rotted pig manure fertilizer in the soil, and then plough the soil to make the fertilizer and soil fully mixed, and then you can sow the seeds of kale on the soil surface, wait for 7-10 days, and the kale will emerge.

2. Watering management

During the growth of kale, it is necessary to control the frequency of watering, so as not to grow the plant in the form of rapeseed, and when the kale enters the formation period of rapeseed, it is necessary to increase the frequency of watering to increase the yield of the plant.

3. Loosen the soil and pull weeds

The growth of kale in the early stage is slow, when breeding kale, it is necessary to cultivate and pull weeds in time, so as not to rob the weeds of the nutrients of the plant, and when the upper part of the kale is thicker and the base is finer, the soil is loosened for it, so that the plant grows roots, and it is necessary to apply well-rotted organic fertilizer for the kale to make it grow vigorously.

<> 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.

Different varieties, sowing time is also different, Hong Kong white flower kale, willow leaf early kale and other early-maturing varieties in mid-April to early August sowing, selected flowers, medium late mustard and other late maturing varieties in September to March of the second year to ensure that November to the second year of May **, pay attention to July to September in the north is a high temperature weather, should choose a cool place to plant.

Kale is the strongest among cabbage vegetables due to its mild climate and strong heat resistance. The suitable temperature for seed germination and seedling growth is 25 degrees Celsius to 30 degrees Celsius, and the growth is slow when it is below 20, and the suitable temperature for leaf cluster growth and vegetable moss formation is 15 degrees Celsius to 25 degrees Celsius, and it likes a large temperature difference between day and night.

When sowing, you can use direct seeding or seedling transplanting, and the northern region uses more seedling transplanting, 70 grams to 100 grams of seeds per mu, and the seedling land should be selected to be convenient for Pai's irrigation sandy loam or loam. When preparing the land, it is necessary to apply more well-rotted organic fertilizer and sow seeds by sprinkling.

Summary. Hello dear, kale is a vegetable with high temperature requirements, and there are fewer cases that require higher temperature in southern Zhejiang, so it is generally not suitable for planting. It is rainy and humid in southern Zhejiang, and the temperature is low, and the temperature in spring and summer is low, so it is not suitable for planting kale, and can only be planted in autumn.

Hello dear, kale is a kind of vegetable with higher temperature requirements, and it is generally not suitable for planting in southern Zhejiang. It is rainy and humid in southern Zhejiang, the temperature is low, the temperature is low in spring and summer, and it is not suitable for planting kale, and Sun Mozhan can only be planted in autumn.

Is the temperature high or low required? Thank you!

Kale requires a low temperature. Kale is hardy and can be grown in temperatures ranging from -8 to -3 degrees Celsius, with the optimum temperature usually between 1 and 4 degrees Celsius.

Is it because the humidity is too high to plant?

You can try planting in late February, or from early July to late August.
