Reasonable fertilization of chrysanthemum, how to water chrysanthemum and how to fertilize chrysanth

If you plant chrysanthemum, it is generally best cultivated in 2 5 months in spring and 7 9 months in autumn, it is best to select seeds for germination treatment, cover them with thin soil after planting, keep the temperature at about 17 20, start watering after the emergence of seedlings, and apply urea every 25 days.

Fertilizer is optimal. 1. Planting time.

There are many friends who do not know about the time and method of planting chrysanthemum, in fact, it is generally best in 2 to 5 months in spring, and it can also be cultivated in 7 and 9 months in autumn, and it is best to sow later, and it is best to plant in April and May in spring, and it can also be planted in August and September in autumn.

2. Choose seeds.

If you want to plant chrysanthemum, you generally choose the seeds that are relatively healthy, full and full for cultivation, and then dry them for 2 hours before germination management, keep watering every day, and germinate in 3 to 5 days.

3. Soil configuration.

Artemisia chrysanthemum likes fertile soil with good loose air permeability, generally using garden map, humus soil, pond mud according to the ratio of 3:2:1 for mixed preparation, and then apply a small amount of organic fertilizer as a substrate, pour in a small amount of water.

4. Planting management.

Artemisia chrysanthemum sowing can be sown or strip sowing, covered with thin soil after sowing, gently compacted, and keep the row spacing at about 10cm, pour a small amount of water after cultivation, and maintain a good ventilation environment is the best.

5. Cold protection and moisturizing.

The growth temperature of chrysanthemum is 17 20, it is best to cover the surface with a layer of plastic film in early spring, wait for the weather to warm, and then uncover the film, when the temperature exceeds 25, it is necessary to strengthen the surrounding ventilation best.

6. Watering and fertilizing.

The seedlings of chrysanthemum should be watered after they emerge from the soil, generally keeping the soil moist, and adding urea solution every 25 days, and applying an appropriate amount of nitrogen, phosphorus and potassium every other month.

Fertilizer is sufficient. 7. Seedling weeding.

When the seedlings grow to 10cm, they are generally cultivated separately, keeping the row spacing of 3 5cm, remembering not to be too dense, and cleaning up the weeds on the soil in time to maintain a good maintenance environment.

Raising chrysanthemum in spring is the fertilization method, and farmers must learn it.

Artemisia chrysanthemum seedlings should be watered after they are unearthed, and the watering time and frequency should be flexibly mastered to keep the soil moist as the standard. 10 15 days before each harvest, 15 kg of potassium nitrate and about 8 kg of urea per mu.

The growth of chrysanthemum requires a large number of nutrients, with the highest proportion of nitrogen, phosphorus and potassium requirements. The main edible part of chrysanthemum is the young stem, and the demand for nitrogen is large in the planting process, so we should mainly use nitrogen fertilizer when fertilizing, with an appropriate amount of phosphorus and potassium fertilizer. The seedling stage of chrysanthemum does not require much nutrients, but when it grows to about 9 true leaves, the fertilizer requirement gradually increases.

Therefore, we need to adjust the water and fertilizer management according to the growth of chrysanthemum to ensure that chrysanthemum grows with sufficient nutrients, and when the plant grows to about 19 cm, it can be harvested.

The growth period of chrysanthemum is relatively short, and the root ability is strong, but the distribution is not deep, and it has strong fertilizer tolerance. Therefore, before planting, it is necessary to apply sufficient base fertilizer, control the amount of base fertilizer according to the planting area, and the base fertilizer is mainly based on fully decomposed farmhouse fertilizer, and then add an appropriate amount of compound fertilizer. Spread it evenly on the top layer of the soil before proceeding with the preparation.

If you use arch shelter planting, then you need to apply base fertilizer in the autumn of the first year to ensure that the soil can fully absorb the fertilizer nutrients and improve soil fertility.

The growth cycle of chrysanthemum is about 40 days, so our top dressing work is very important. Although the growth cycle is short, it should be topdressed about three times during the whole growth period of chrysanthemum. For the first time, chrysanthemum seedlings grow to about 9 cm, and the fertilizer is mainly ammonium sulfate, etc., which improves the growth of seedlings and enhances resistance.

Then when the seedlings grow 3-5 true leaves, they are topdressed again, and the fertilizer is mainly available nitrogen fertilizer. Finally, when the seedlings grow to about 11 cm, top dressing is carried out together with watering, and the fertilizer is mainly compound fertilizer. Because chrysanthemum can be harvested multiple times, we need to top fertilize every time we harvest it, and the frequency of top dressing should be kept at about 1 week to avoid reducing the quality of chrysanthemum.

Summary. Top dressing is applied once each harvest of chrysanthemum, and 20-30kg of Tianji calcium nitrate fertilizer or 15-20kg of Tianji phosphorus and potassium nitrate fertilizer (20-9-9) are applied per mu each time. It is better to apply thin fertilizer frequently, but the next harvest should have an interval of more than 7-10 days between the last fertilizer application to ensure product quality.

In the case of sufficient basal fertilizer, fast-acting fertilizer should be applied once after each harvest to facilitate subsequent growth.

More application of farmhouse well-rotted organic fertilizer and some water-soluble fertilizer, water and fertilizer integration is better.

Do I need to apply calcium fertilizer to grow chrysanthemum?

Hello, yes. However, if you want to eat it yourself, it is best to use organic fertilizer.

Although it may be thinner, it is an organic vegetable after all.

Is calcium fertilizer bad for chrysanthemum?

There are no disadvantages.

It can grow stronger.

Did you grow it yourself and eat it yourself?

You can use some compound fertilizer.

No, it's for sale.

Yes, calcium fertilizer can improve the soil.

Calcium fertilizers mainly include calcium nitrate, chelated calcium, sugar alcohol calcium, etc., and there should be a difference when choosing.

Top dressing is applied once each harvest of chrysanthemum, and 20-30kg of Tianji calcium nitrate fertilizer or 15-20kg of Tianji phosphorus and potassium nitrate fertilizer (20-9-9) are applied per mu each time. It is better to apply thin fertilizer frequently, but the next fertilization should have an interval of 7-10 days to hold the orange on the last fertilization to ensure product quality. In the case of sufficient basal fertilizer, fast-acting fertilizer should be applied once after each harvest to facilitate subsequent growth.

The hall skin digging more farmhouse decomposed organic fertilizer and some water-soluble fertilizer, the integration of water and fertilizer is better.

1 Prepare the land. Select sandy loam soil, plough in time, and apply a small amount of dry manure as base fertilizer, the ground should be watered thoroughly before sowing, and at the same time spray new high-fat film to protect moisture and waterproof evaporation, prevent soil layer compaction, and isolate the source of diseases and insects.

2 Seed treatment. Soak the seeds in warm water for 24 hours, remove them and dry them for a while to promote germination under 15 20 conditions, and mix the seeds with a new high-fat film before sowing to form a protective film, which can repel underground diseases and insects and improve the germination rate of seeds.

3 Field management. According to the growth needs of chrysanthemum, watering, fertilization, weeding, pest control should be timely watering, fertilization, weeding, pest control, in the growth stage of chrysanthemum should be sprayed in a timely manner to strengthen the stem of vegetables, so that chrysanthemum leaves are thick, the leaf color is fresh and tender, so that chrysanthemum natural taste is strong, and at the same time can improve the disease resistance of chrysanthemum, so that chrysanthemum is of high quality and high yield.

Artemisia chrysanthemum belongs to shallow rhizome vegetables and fruits, which grow and develop faster, sparsely planted, and the total area of nutrients in a single tree is not largeAlthough the regulations on the soil layer are not too strict, it is better to use the rich soil layer, and the chrysanthemum is based on the leaf and stem as a commodity, so the fast-acting basal fertilizer should be the dominant fertilizer. The base fertilizer of chrysanthemum is closely combined with organic fertilizer and inorganic fertilizer, fertilizer and tillage are closely combined, 2000 3000kg of high-quality farmhouse fertilizer per mu of medium-level fertilizer efficiency land, 1000 2000 cm of high-quality farmhouse fertilizer per mu of land with high fertility, and appropriate compound fertilizer is matched with each other.

Artemisia chrysanthemum sprouts 3 cm up and down watering, 10 cm up and down gradually fertilization, with fermented organic fertilizer and fast-acting base fertilizer closely combined, after each picking, can be applied 15 20 kg of urea solution per mu. The chrysanthemum planted in the reserve is generally in good weather when 8 leaves are up and down, mixed with watering, and 15 20kg of ammonium sulfate per mu, or 10 kg of urea solution. Artemisia chrysanthemum is a leafy vegetable and fruit with fast natural nature, in order to better grow and develop fast, good quality, fertilizer should be integrated with watering, with fast-acting base fertilizer as the leading, can be carried out with organic fertilizer of manure.

Artemisia chrysanthemum can be planted on average a year, the best natural environment is spring 2-4 months, autumn 9-11 months, before planting the seeds can be carried out to promote teeth, improve the germination rate, (chrysanthemum has strong adaptability, generally immediately sown can), the seeds are soaked in 50 degrees warm boiling water for 10min, and then refrigerated to 20 degrees soaked for 24 hours, scooped up and drained water, put into the greenhouse to promote teeth, and the buds can be planted when they leak white. When planting, make the ground into furrows, rake them finely and flatly, sow them evenly immediately, cover them with a thin layer of soil, and water them immediately. Budding can occur within a week after planting.

According to the size of the leaves of chrysanthemum, chrysanthemum is usually divided into two types: pointed leaves and twigs. Among them, Artemisia macrophylla has weak cold resistance, but the material is soft, suitable for planting in the northern region, and the twigs are also called flower-leaved chrysanthemum, which is characterized by strong cold resistanceThe material is slightly less smooth than the large-leaved species, and it is mostly planted in North China.

When fertilizing, the soil needs to be fertilized first, and the soil must also be disinfected and sterilized. When chrysanthemum grows to a certain height or after germination, top dressing is required.

It is very important to fertilize chrysanthemum in the process of planting, and it is necessary to choose the right time to do right and wrong, and to water it, so that it can grow better.

Peers can choose boron fertilizer, potassium fertilizer, nitrogen fertilizer, phosphate fertilizer, or natural fertilizer manure according to the characteristics of the soil; When topdressing, the amount should be selected according to the pH and absorption degree of the soil, as well as the degree of sunlight exposure.

The planting techniques and management methods of chrysanthemum are as follows:

1. Prepare the land and make furrows

The planting plot is generally a slightly acidic soil with loose and fertile soil with good drainage, and neutral soil is also acceptable. Before sowing, the basal fertilizer should be applied well, so that the fertilizer and the soil are fully mixed evenly. When making furrows, the width of the furrow is generally to, and the length can be determined according to the actual size of the planting area.

2. DipSeed germination

Germination is generally about three to four days before sowing, first put the chrysanthemum seeds into 30 degrees of warm water to soak for a day, and then wash and dry, and then can be diluted 300 times by Yifuyuan planting fungus solution for two to three hours, placed in 25 conditions to promote germination, wash once a day, spray 3 times a day to plant 300 times dilution of the fungus solution, seeds can be sown after 3-4 days of germination.

3. Transplant in a timely manner

When transplanting, you can use a sickle to raise seedlings, put them into the prepared pots, and then transplant them into the planting ground, the plant row spacing is generally about four to six centimeters, after the transplanting is completed, the planting ground will be watered thoroughly, and nitrogen fertilizer will be applied once in the 20 days of the transplanting hall.

4. Reasonable top dressing

When the chrysanthemum seedlings grow to 10 to 12 centimeters, they should be topdressed once, and then they should be topdressed once every time they are harvested. Top dressing is generally used with water top dressing, the fertilizer is evenly sprinkled at the water inlet, and the water is directly irrigated, and the fertilizer can not be directly sprinkled in the ground, so as not to burn the chrysanthemum leaves. During the growth period, 1-2 times of available nitrogen fertilizer should be chased with water, and 15-20 kg of urea per mu should be used each time.

5. Pest control

Reasonable fertilization and watering, avoid big and small; The hidden management of temperature traces does not fluctuate high and low, creates a good ecological environment, promotes the healthy growth of plants, reduces the harm of pests and diseases and pesticide application, and maintains the ecological balance.

6. Harvest at the right time

When the plant of chrysanthemum is about 20 cm high and has 12-13 true leaves, it should not be harvested too late, so as not to affect the quality. When harvesting, you can use a knife to leave 2-3 leaves at the base of the stem to cut off, then remove the yellow leaves, and tie the chrysanthemum into small handfuls**. Generally, it can be harvested once in 20-25 days, and each stubble can be harvested 2-3 times.
