There are many people who grow kale now, do you know what planting skills kale has?

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.

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.

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.

1. Soil: Kale does not have many soil requirements for the planting site, but it is best not to carry out continuous cropping, and the planting land where the previous crop is cruciferous is not suitable for planting kale. If you want kale to be productive, it is best to choose sandy loam or loam soil with abundant organic matter, strong water and fertilizer retention, and moderate pH.

Do not plant in heavy clay and sandy soils, which are too permeable.

2. Fertilization: The growth of kale has a large demand for nutrients, but we must carry out reasonable topdressing. During the growing period of kale, there are not many nutrients required, so there is no need for top dressing when the basal fertilizer is applied sufficiently.

After the seedlings are well developed, when the flower sprouts slowly grow, we need to carry out top dressing, mainly with nitrogen, phosphorus and potassium ternary compound fertilizer for top dressing, of which the proportion of potassium fertilizer should be the largest, because kale has the strongest absorption capacity for potassium. Of course, if there are conditions, it is best to use a combination of organic fertilizer and chemical fertilizer to deliberately improve the quality of kale.

3. Temperature: Kale has requirements for temperature. The germination of kale seeds is generally in an 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 development of kale, and may even cause the plant to wilt, so it is best to physically cool down in the summer.

4. Moisture: Kale has a large demand for water during the whole growth period, because it has the characteristics of loving moisture and not being drought tolerant. Then we should water frequently in the growth process of kale, keep the soil moist, the humidity in the field is best controlled at about 85%, of course, the amount of watering each time is not too large, although it has a strong resistance to waterlogging, but if there is too much water, it will also cause the root rot of the plant.

5. Light: Kale is a vegetable that is extremely intolerant to shade, so it needs to have sufficient light during its growth. Although it does not require the duration of light, it is necessary to maintain uniform light every day, and there can be no shortage of light, otherwise the development of kale will be relatively slow, and it is easy to stunted.

Kale is suitable for planting in several months.

Kale is one of China's specialty vegetables. Generally, the repentant skin is sown in February and March every year, the growth rate is fast, and it can mature in June and October. Medium-late maturing varieties can also be planted around November each year.

1. Soil preparation and fertilization.

To plant kale, it is necessary to choose fertile soil with good water and fertilizer retention, and then apply an appropriate amount of basal fertilizer per mu, turn it into the soil, and mix well. The soil needs to be tilled and leveled, and finally leveled to make a border.

2. Handle tubers.

Kale can be sown by transplanting seedlings or directly in the open fields in the south. The land on which the seedlings are raised is preferably sandy loam, and the front stubble of this planting site should not be cruciferous vegetables.

Points to note when planting kale.

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

2.Kale grows slowly in the early stages and is prone to weeds. Therefore, it is necessary to carry out weeding in a timely manner, and at the same time, it is necessary to combine soil tillage and fertilization. The best fertilizer is organic fertilizer.
