How profitable is growing kale? What are the precautions for cultivation?

The profit is still very good, but when planting, you must pay attention to the control of temperature and nutrition, which is also the details of this plant.

The profit is considerable, in the cultivation season, all over Shandong, kale can be cultivated in spring and autumn. Spring stubble is sown in February and March, and the harvest period is May and June; Autumn stubble can be sown in July and August, and harvested in October and November.

The profit margin of growing kale is relatively large. When cultivating, pay attention to the key matters of fertilization time, watering amount, and soil ratio.

Now the profit is still very good, there is a big gap in the market, when planting, we must learn the geographical environment, as well as the climate, try to water as much as possible, fertilize more, and reduce pests.

In fact, the profit of planting kale is very high, the first point should pay attention to its water must achieve the purpose, the second point should also be timely fertilization, so that it can, the third point should be timely watering, so as to achieve a very ideal effect.

There are not many soil regulations for kale, but it is better not to carry out continuous planting, and there are also planting areas where the previous crop is cruciferous is not suitable for growing kale. If you want to increase the yield of kale, it is best to choose sandy soil or loam soil with a moderate pH value that contains a variety of organic substances, has good water retention and soil fixing. It does not have to be planted in heavy clay and sandy soils, and the permeability is very poor.

The growth of kale requires a large amount of nutrients, but we must carry out topdressing scientifically and reasonably. During the growing season of kale, few nutrients are required, so it is not necessary to carry out top dressing when the base fertilizer is sufficient. Until the seedlings are well developed, slowly grow out of the flower sprouts, we must carry out top dressing, the key is to carry out top dressing with nitrogen, phosphorus and potassium fertilizer, in which the ratio of potassium fertilizer should be larger, because kale has the strongest adsorption capacity for zinc.

Naturally, if there is a premise, it is best to apply organic fertilizer and organic fertilizer together, so as to intentionally improve the quality of kale.

Kale has certain temperature regulations. The germination of kale seeds is generally in a natural environment with a temperature of 25 to 30 degrees, and the best temperature for kale to grow flowers is between 15 and 25 degrees, and it is best to have a large temperature difference between day and night, which is more conducive to the growth of kale. If the temperature exceeds 30 degrees, it is very bad for the growth and development of kale, and may even cause the plant to wither, so it is best to carry out physical fever reduction in the summer.

Kale requires too much water throughout its growing season because it is moisture-loving and drought-tolerant. Therefore, we should water frequently in the case of kale growth, always keep the soil moist, the environmental humidity of the farmland is best manipulated at about 85 percent, and the amount of natural watering each time is not very large, although it is very resistant to waterlogging, but if there is too much water, it will cause the plant rhizome to rot.

Kale is a very shade-tolerant vegetable and fruit, so it must have enough light when it grows. Although it does not require the duration of light, it is necessary to maintain uniform light every day, and there should be no shortage of light, otherwise the growth of kale will be very slow and it is very prone to undergrowth.

We must choose to dredge the fertile soil, and to properly turn the soil before planting, but also sufficient light conditions, to strengthen the management of water and fertilizer, appropriate watering and fertilization, but also to do a good job in pest control.

The suitable temperature for the growth and development of kale is 15 25 degrees, the temperature of seed germination is 25 degrees to 30 degrees, when the card is delisted in the spring, it is best to sow seedlings around March and receive them in June, and in autumn they can be sown in July and August, harvested in November, if in winter, you can use the electric hotbed greenhouse to set up the seedbed for pre-seedling, the soil conditions are not very strict, the fertile soil is the best, you can use some protective molds to protect the mulch, to do a good job in field management, covering and insulation, Adjust the indoor temperature according to climate change, and scientifically top dressing nitrogen, phosphorus and potassium compound fertilizers are best mixed.

It can be planted directly in the greenhouse, the temperature can not be higher than 30 degrees, otherwise it will be sunburned, you need to pay attention to the cooling treatment, and choose the right variety for the device.

Selection of suitable varieties: The cold resistance of different leek varieties varies greatly, generally speaking, the deeper the low temperature dormancy of a loss-bearing variety, the stronger the adaptability to severe winter low temperatures. Therefore, it is best to choose some dormant varieties for the production of open-field dry leeks in cold areas in winter, such as Fufeng No. 1, Jin Leek No. 1, Bamboo Pole Green, Big Bend Seedlings, etc.

Some non-dormant varieties can also be used in North China, but the corresponding cold protection work must be done.

You can refer to the practice of the vegetable farmer's first round shed, use plastic wrap to build a small shed, to achieve the purpose of heat preservation, tie a few vents, and water regularly and appropriately to ensure a good living environment.

Land preparation for furrowing: 2500 3000 kg of fully decomposed pig manure socks or chicken manure per mu of planting field, 50 kg of superphosphate and 25 kg of potassium sulfate compound fertilizer, deep plough and rake are flat, and the deep ditch and high furrow are made into a deep ditch with a wide meter of slippery ditch.

<> kale is a more nutritious vegetable in cabbage vegetables, which can be stir-fried, souped, or used as a side dish, and can be planted in many places.

Kale is suitable for planting in loam soils with fertile soil at 18-27 with a humidity of 70%-85%. The planting time is February-March in spring or September in autumn. During the planting period, when the seedlings grow 4 true leaf hail stalls, they can start transplanting and planting in the field, and the top dressing 2-3 times during the growth period can ensure the yield.

Kale can be planted throughout the year, because its varieties are early-maturing, mid-late maturing, of which the early-maturing ones need to be planted in the open field, and can be planted between June and October, if it is planted from September to March of the following year, it is necessary to use medium-late maturing varieties, and when sowing, seedling transplanting can be used, or live broadcasting.

Kale planting time.

Kale can be planted all year round in the stuffy bush, because its varieties are early-maturing, mid-late maturing, of which the early-maturing ones need to be planted in the open field, and can be planted between June and October, and if they are planted from September to March of the following year, medium-late maturing varieties need to be used.

Kale cultivation method.

1. Seeding treatment:Kale can be planted by transplanting seedlings or direct seeding, but before sowing, it is necessary to prepare the land and fertilize it to make the plot loose and fertile, and then it can be sown directly.

2. Seedling managementWhen kale is in the seedling stage, it needs to be fertilized in time, three quick-acting fertilizers need to be used, and seedlings should be thinned regularly to avoid seedlings growing too densely, otherwise it will grow.

3. Colonization method:When kale is planted in the open field, it needs to be planted in the Zheng shed in the afternoon, and the seedbed should be watered thoroughly, and there should be a suitable row spacing, not too dense, not too deep.

Precautions for kale planting.

Kale needs to be paid attention to when maintaining at the seedling stage, we must weed in time to avoid absorbing too many nutrients, and have a good ventilation environment during the maintenance period, as well as sufficient sunlight, which are more important for its growth and can make it have good growth.
