Kale is a very popular vegetable, so what do you need to pay attention to when growing kale?

To choose high-quality seeds, to do a good job of seed seedling, planting must pay attention to the density, should also pay attention to the temperature, to ensure that the bottom fertilizer is sufficient.

Pay attention to the method of planting, pay attention to the nutrition of the soil, pay attention to the surrounding environment, pay attention to the weather, pay attention to the amount of water.

I think we need to pay attention to the soil problem, the planting problem, the weather problem, the fertilization problem and the water problem.

The first point is the choice of planting environment area, purple cabbage is a vegetable that prefers to grow in a mild environment, and the temperature requirements are not too high, as long as the temperature is not lower than minus 5 degrees or higher than 35 degrees. Cabbage prefers cold climatic conditions, the suitable growth temperature is above 10 degrees, below 20 degrees, the suitable temperature for seed germination is between 18 and 20 degrees, and the temperature is above 25 degrees, it will grow poorly. Cabbage prefers moist soil environments and grows well in moist soils.

Purple cabbage belongs to a kind of cabbage, the color is purple, the nutritional value is high, the price is expensive, you can also eat it coldly and raw, the taste is good, the planting time of purple cabbage is about the same as the time of planting Chinese cabbage, it is generally planted from September to early October, first seedlings, and then transplanted. Spray pesticides in time to prevent seedlings from being damaged by pests and diseases. 3. Post-autumn management technology When the true leaves grow to 7-8 pieces, the purple cabbage seedlings are planted upside down in the modified yang furrow or solar greenhouse according to the row spacing of 25-30 cm, so as to ensure safe wintering and raise strong seedlings for spring planting.

Cabbage is also called cabbage, cabbage, lotus white, according to the shape of the leaf ball, divided into three types: flat head, garden head and pointed head. The cabbage plant is small, the leaf bulb is small and pointed, resembling a heart, and the heart is generally loose, but it is early maturing and has strong winter. The 70-90 days from planting to harvest mainly refers to a cabbage variety that is sown in winter, planted in spring, and harvested in summer.

In general, it is recommended to choose early-maturing varieties with strong cold tolerance, and sow and raise seedlings in greenhouses in early February in some monoculture areas such as Northeast China, North China, and Northwest China.

The best time to plant is spring and autumn, April and September are the most suitable for planting, at this time planting will also have a very good harvest, and the planting period should also ensure nutrition, so that the harvest can also be very good.

Cabbage is more suitable for planting in autumn and winter, because cabbage has a higher sugar content and is in high demand in autumn and winter.

It is best planted in early spring, when the weather is more suitable and allows the cabbage to grow better.

1. Top dressing: cabbage has different requirements for various fertilizers at different growth stages. At the early stage of growth, more phosphorus and potassium fertilizers were applied to plant growth, and nitrogen fertilizer had the greatest impact on yield.

The first top dressing is carried out after the colonization survives. 1000 kg of human urine per mu. The second topdressing is about half a month away from the first topdressing; Half water and half manure, 1500 kg of manure per mu.

The third top dressing, at the beginning of seedling pumping, 2000 kg of manure per mu. At this time, phosphorus and potassium fertilizers can be applied as appropriate. When topdressing, do not spray manure on the leaves to avoid rotting.

2. Irrigation: After planting, irrigate once, and then suspend watering for 1-2 weeks to dry the soil slightly and promote root development. This method is called squatting.

After squatting, irrigation and top dressing were carried out once to promote the rapid growth of cabbage. After increasing the amount of irrigation, especially when the cabbage needs a lot of water. At this time, irrigation can increase yields and harvest earlier.

Stop irrigation before harvesting to avoid leaf cracking due to excessive water absorption. The frequency of irrigation depends on weather conditions.

3. Cultivating: Cultivating can loosen the soil, promote root growth, and reduce water evaporation. At the same time, weeding and soil culture can be used to promote the growth of adventitious roots and stabilize the plant.

After planting, the second top dressing and tillage are carried out, the hardened topsoil is hoeed, the planting hole is filled and the soil is cultivated. After the second topdressing, the second tillage was carried out, and shallow hoeing was carried out in the root growth area; Combine weeding and soil tillage. After the third top dressing, the third intercropping should be carried out.

Be careful not to break the stems and leaves in the cultivator. In the later stage of growth, the cultivator should not be too deep to avoid damage to the root system.

4. Pests and diseases and their control: cabbage is the most serious pest and disease month. Generally, it is sprayed with powder, 200 times 6% wettable 666 or 250 times 10% 666 emulsion.

When the larvae of Noctuidae first hatch, they gather on the back of the leaves and can be artificially killed in October and November, with the velvet white snail (green worm) being the most harmful. Chemicals can be sprayed, generally mixed with 228 and 666.

Black rot is prone to occur at high temperatures. The affected branches and leaves first turn yellow from the center of the leaf, then extend inward to the veins of the leaf, and gradually turn black. Eventually, all kale leaves will turn black, rot, and stink.

If a diseased plant is found, it should be removed immediately. The black dot is a small black dot at the beginning of the leaf. In wet weather, it quickly expands into grayish-white or even black dots with a black dot in the center.

The seed pods often start at the tip and change from light purple to brown in the affected area. In severe cases, the seed pods will wilt. Control with Bordeaux solution (prepared with 1 kg of lime, 1 kg of copper sulphate and 120 kg of water).

Field management needs to pay attention to the need to have enough moisture, to contact the rainwater irrigation, be careful not to use strong light, if the temperature is relatively high, it needs to be covered.

It should be noted that it must be watered 2 or 3 times a week, and top dressing must be carried out during field management, and the first top dressing must be carried out after planting.

It is necessary to pay attention to the time of field management, pay attention to the changes in the soil, pay attention to the condition of the cabbage, remember to kill insects, water, and fertilize.

Choose the variety, sow it properly, cultivate the seedlings, prepare fertilizers and pesticides, and water it more, so that you can do a good job in field management.

Cabbage is also called cabbage, cabbage, cabbage, etc., in our local area, people are used to calling it cabbage. Cabbage is very adaptable, has a strong heat and cold resistance, its disease resistance is strong, wide adaptability, in most areas of our country can be cultivated in the open field in spring, summer and autumn and overwintering cultivation in protected areas, the Yangtze River in the lower reaches and south of the region, and even can be cultivated all year round.

Cabbage cabbage has high nutritional value, and the eating methods are diverse, it can be fried or cold raw food, and can be processed into kimchi, pickled, dried, etc., and its market demand is very large, so it has attracted a large number of farmers to plant, especially the use of protected land for off-season planting, and the vegetables are listed in the off-season, which can be much higher than the peak season.

Purple cabbage, so when is the cabbage grown? The main cultivation seasons are as follows for farmers to learn from.

Spring cabbage refers to a type of cabbage variety that is sown in winter, planted in spring, and harvested in summer. Spring cabbage generally chooses early-maturing varieties with strong cold tolerance. In the Northeast, North China, Northwest and other single-main planting areas, seedlings are sown in greenhouses in early February, and seedlings are planted in cold beds or plastic arch sheds, and planted in the open field from late April to early May.

Kale transplanting. North China, Jinan and other double main cropping areas from the end of January to the beginning of February in the yang furrow sowing seedlings, or in early February in the greenhouse sowing seedlings, seedlings to the yang furrow. In the southern region, seedlings are sown in the open field in mid to late October, planted in late November to early December, and harvested in April and May of the following year.

Cabbage grown. Summer cabbage refers to a type of cabbage variety that is raised in spring and summer, and harvested in summer and autumn. Varieties with strong heat resistance, humidity tolerance and disease resistance are generally selected for planting. Summer cabbage is generally sown in early and mid-May, planted in the open field or under shade nets and insect-proof net facilities in early and mid-June, and marketed from early to mid-August to early September.

Not only the production cost is low, but also can solve the problem of the shortage of vegetables in Futian, and the market is generally good.

Cabbage grown. It refers to the cabbage-like varieties that are raised in late summer, planted in early autumn, and harvested in late autumn and early winter. It is mostly sown from mid to late June to early and mid-July, planted from mid-July to mid-August, and harvested and marketed from early and mid-October to mid-to-late November. High yield, play a definite role in solving the winter vegetable off-season, high economic benefits, is one of the main cultivation methods of Brussels sprouts.

Choose early-maturing varieties that are heat-tolerant and disease-resistant, or medium-late-maturing varieties that are heat-tolerant, moisture-tolerant, disease-resistant, high-yielding, and cold-tolerant.

A bumper harvest of kale. It refers to a type of cabbage variety that is raised in summer and autumn, planted in autumn and winter, and harvested from winter to early spring. Choose late-maturing varieties with high yield, disease resistance, cold tolerance and strong winter. Because the market time is during the New Year's Day or Spring Festival, it is relatively high, and the benefits are also very considerable, which is a new cultivation method to meet people's diversified consumption needs.

Different varieties of cabbage have different growth cycles, summer cabbage growth cycle is 45 days, and its bulb will be relatively small. The late-maturing variety of cabbage has a cycle of 90 days, and its bulbs are relatively large and the yield is high.

It is also called cabbage, cabbage, people are used to calling it cabbage. Different varieties of cabbage have different growth cycles, with a summer growth cycle of 45 days, while late-maturing varieties of cabbage have a growth cycle of up to 90 days, which has larger bulbs and higher yields.

The growth period of early-maturing cabbage is 50-60 days, which is suitable for seedling greenhouse planting in early January, seedling cultivation in early February, and the growth period of late-maturing cabbage is about 90 days, and seedlings are raised in early June.

Overwintering cabbage cultivars determine their yield, so choose a wintering variety that is suitable for planting in the local winter climate. Varieties must have the characteristics of strong cold resistance, low wintering, strong resistance, and long growth period. Cabbage has strong heat tolerance and can be sown in hot summer, more than late June to July, early varieties are sown early, late varieties are sown.

In summer, there is high temperature and drought, and sometimes there are showers, so when raising seedlings, it is necessary to choose the land with good drainage, fertile soil and close to the water source as the seedbed.

There are many varieties of cabbage, and different varieties are suitable for planting in different regions and times. Cabbage is cold tolerant and heat-tolerant, but its suitable temperature for growing is 20-28, so it is the best time to plant cabbage in April and September every year. Cabbage planting is to take the seeds to sow seedlings and then transplant and plant, take the seedlings of the vegetable field to plough the soil exposed to the sun and water enough water to make the seedbed soil finer, there is a certain degree of porosity, wetness, apply enough farm fertilizer as the bottom, farm fertilizer can be rotten dry manure farm fertilizer.

Make a seedbed: The seedbed should be selected with good ventilation, high terrain, convenient drainage and irrigation, no vegetables of the same family, and pollution-free plots close to the planting field. The formula of seedbed soil is 6 parts of field soil, 4 parts of well-rotted organic fertilizer, 1 kilogram of ternary compound fertilizer is added to each cubic meter of nutrient soil to select early maturing varieties with short growth period and high yield, and the weight of each fruit is about one kilogram as well, and it can be harvested about 45 days after planting.

Cabbage has strict requirements for the temperature of balling, which is generally controlled at about 17 degrees Celsius.

Cabbage has strong adaptability, and does not need to choose specific soil and soil quality to plant, it should be noted that Ganyan agitated blue can not be continuously cropped, otherwise it is prone to plague. Before planting, remove the debris in the field, turn the soil deeply, expose it to the sun for a few days, and then prepare the land to make furrows and dig drainage ditches. Cabbage sowing is generally carried out at noon on a sunny day, after leveling the seedbed, slightly suppressed, watered through the bottom water, sprinkled with a layer of fine nutrient soil, covered with soil after seed sowing, the thickness is 1 cm is appropriate, and do a good job of heat preservation and moisturizing.

Select varieties to choose early-maturing varieties with short growth period, a single ball weighs about 1 kg, and is about 45 days after planting to the harvest period, which is more suitable for the consumption habits of consumers, and does not affect the sowing period of the next stubble overwintering vegetables, such as Dutch varieties such as Switzerland. Sowing cabbage seedlings in time is not strict on the temperature of cherry rot, but the temperature requirements for the setting stage are very strict, which should be about 17, which is conducive to the formation and growth of leaf bulbs. Therefore, the summer sowing time is around late July.

3. Cultivate strong seedlings 1To make a seedbed: the seedbed should be selected with good ventilation, high terrain, convenient drainage and irrigation, no vegetables of the same family of Lihong have not been planted, and pollution-free plots close to the planting field.

First of all, it is necessary to choose early-maturing varieties, and to choose the right temperature and time for spine sowing, and then to do a good job of drainage and irrigation, and must do a good job of sowing and seedling, and then to strengthen management, and to spray pesticides in a timely manner, must be reasonable management and shouting wisdom, and then to choose September for harvesting.

Generally in July around the sowing of seeds, to choose a piece of soil is more fertile, ventilation is better, water seepage effect is better dry soil, this land is best not planted with the same family of vegetables, there is no pollution, to prepare a state of some organic fertilizer, but also to prepare some cracked compound fertilizer, keep a certain distance, and then plant it, the seeds should be planted after the work of insect control, cabbage can generally be harvested in September.

First of all, when planting, we must choose a more fertile and wide soil with a lot of soil, and use farmhouse fertilizer, do not use the fertilizer bought outside, water the plant more, and prevent the occurrence of pests and diseases.
