Cultivation techniques of cornflower with the effect of "monitoring sulfur dioxide"

Cornflower was originally a wild flower from Europe. After years of cultivation, the "wild" nature of corn chrysanthemum gradually decreases. Today's cornflower flowers are larger and colorful, of which purple and blue are the most valuable. Let's take a look at the planting and cultivation techniques of corn chrysanthemum together with the editor of Huinong Network.

1. Monitoring efficacy

Cornflower can monitor sulfur dioxide. When the concentration of sulfur dioxide in the air is high, the corn chrysanthemum will lose water and become dry and cannot blossom normally.

two。 Planting technology

(1) selecting basin

Planting cornflower should not choose plastic basin or porcelain basin with poor air permeability, which can easily lead to rotten roots, so it is best to choose mud basin.

(2) soil selection

Cornflower is suitable for growing in soil with fertility, loose soil, smooth drainage and sandy soil, and the basin soil should have good ventilation and drainage.

(3) cultivation

First of all, select the plant before cultivation, the young plants of corn chrysanthemum had better choose those that have grown 6-7 leaves, and then transplant to the flowerpot. Prepare fertile and loose soil in the flowerpot, gently compact the soil at the root base of the young plant, pour enough water, and put the flowerpot in a warm and ventilated place for normal maintenance and management.

(4) Lighting

The growth environment of cornflower must meet the conditions of good ventilation and sufficient light, otherwise, it will die because of the dark and humid environment.

(5) temperature

Cornflower likes to grow in a cool and cool environment, has a certain degree of cold resistance, even in cold winter, as long as the indoor temperature is suitable, the suitable temperature is generally 8-15 ℃.

(6) watering

It is usually watered once a day. Summer is prone to drought, need to be watered in the morning and evening, in order to maintain the wettability of the basin soil, but also to cool the basin soil, but the amount of water can not be too much, not allowed to have stagnant water. Because the cornflower can not grow normally in a dark and humid environment, it must be watered properly every time during the growing season. Too much water will lead to too much moisture in the basin soil and cause the root system of the plant to rot.

(7) fertilization

Before planting, you should apply base fertilizer to the cornflower once, and then apply liquid fertilizer once a month to ensure the normal growth of the plant, until the emergence of buds, stop fertilization.

(8) Reproduction

The propagation method of cornflower is sowing, which can be carried out in both spring and autumn, and it is appropriate to sow in autumn.

(9) pruning

The stem of Chrysanthemum morifolium is thin and weak, so the coring treatment should be carried out at the seedling stage in order to make the plant grow low and promote the sprouting of lateral branches.

(10) arrangement and arrangement

Cornflowers like light, can be planted or placed in the balcony, windowsill and other sunny places, can also be used as a cut flower decoration restaurant, living room, study.

The above is the planting and cultivation techniques of cornflower sorted out by Huinong net Xiaobian. Have you learned all these? The corncar chrysanthemum is in full bloom with beautiful flowers and bright colors. Passionate flower friends can try to breed.

How to cultivate cornflower? Cultivation and maintenance skills of cornflower

Corn chrysanthemum has the characteristics of elegant plant type, beautiful flower pattern, rich flower color and very good ornamental value. it is understood that this flower originated in Europe and is currently the national flower of Germany, and later it was introduced in many areas of our country. Here are the detailed cultivation and maintenance skills of corn chrysanthemum. You can try it.

Environment

Cornflower is more adaptable, like the sunny, cool environment, more cold and afraid of heat, not resistant to shade and waterlogging. Like loose, fertile, well-drained sandy soil; choose a location with plenty of sunshine and good drainage, otherwise it will often lead to death due to dampness. Potted cornflower was cultivated in a pot with a mixture of garden soil, rotten leaf soil, plant ash and river sand.

Administration and Management

The seeds of cornflower can be propagated by self-sowing, have strong adaptability and are easy to cultivate. In the south, the seeds were sown in August, planted in September, and flowers could be produced in February of the following year. The north can sow seeds in early spring and blossom in June. Cornflower cultivation should not be too dense, need to pick the heart after planting, can promote more branches, can blossom more; if there are too many branches, you can pick part of the lateral buds, so that the flowers are larger. And maintain a ventilated environment.

Water and fertilizer

Corn chrysanthemum likes fertilizer, afraid that the soil water will rot, keep sufficient water and fertilizer during the growing period, apply nitrogen, phosphorus and potassium water fertilizer every 20 days, stop nitrogen fertilizer in flower buds, water can be irrigated in the morning and evening in the hot summer, timely drainage in the rainy season, and sprinkle water to cool down in the high temperature period. Water control in winter.

Sunshine

The cornflower likes light and can shine all day in other seasons except the hot summer. Only the water and fertilizer are enough to make the flowers of the plant large and beautiful. Cornflower is not only sown in spring and autumn and summer. The seeds are sown from April to May and can blossom from July to October of that year. The corn chrysanthemum planted in the north is shielded or moved into the flowerpot with mulch in winter, and the flowerpot is placed in a sunny position indoors in late October, keeping the room temperature at 8 degrees to survive the winter.

Corncar chrysanthemum flower color has a very good ornamental value, generally can be planted in potted plants or flower beds. Can also do cut flowers, worthy of your love of flowers and plants to plant yo.

Detailed explanation of the cultivation techniques of corn chrysanthemum!

The hometown of cornflower is in Europe, it was originally a kind of wild flower, after many years of cultivation, its "wild" nature is less, the flower is bigger, the color is more, there are purple, blue, light red, white and other varieties, of which purple and blue are the most valuable. It can be found everywhere in Germany's hillsides, fields, watersides, roadsides, front and back houses, and it is regarded as the national flower by Germany. Today, I would like to briefly introduce the cultivation techniques of corn chrysanthemum. Cultivation techniques of cornflower chrysanthemum like sunny, cool climate, avoid hot summer, suitable for fertile and loose soil. Because of the straight root, it is suitable for live broadcast. Autumn sowing is early flowering, overwintering in a cold bed, and flowering at the end of spring. Cornflower is not tolerant to transplant, so it must bring soil mass when transplanting, otherwise it is not easy to slow down the seedlings. After the planting survived, the feces and urine of mature people with 5 times water were applied every 10 days or every month, and the fertilization was stopped in March of the following year to wait for flowering. If the pot culture of cornflower is used, the pot soil should be loose and fertile, and it is best to use garden soil rotten leaves, plant ash and so on to mix the soil. When the seedlings have six or seven leaves, they should be transplanted for the first time. In the future, it will be changed to at least three pots, because the cornflower has straight roots, and the big seedlings are not resistant to transplanting. Winter can be continuously buried in the soil for the winter, wait until the first ten days of March to take out, fertilization should be diligent, to stop fertilization when buds appear. Cornflower has strong cold tolerance and can be planted in open land in East China, but it must be covered in North China to survive the winter. Like fertile and loose soil, like plenty of sunshine, self-sowing. It is adaptable and easy to cultivate. Cut flowers are usually cultivated in greenhouses, sowed in August, planted in September, and can produce flowers in February of the following year. The warm land in the customs is generally sown from August to September, the open field is covered with overwintering, it is planted in early spring of the following year, and blossoms in early summer. The northeast is sown in spring in the greenhouse. Because the root of cornflower is taproot and the lateral root is very few, so transplanting should bring soil into the seedling, and if the seedling is large, it is not easy to survive, so it is often direct seeded in spring. Cornflower can also be self-sowing and reproduce, in addition, cornflower likes close planting, otherwise it will grow poorly. The corncar chrysanthemum is rich in color and unique in shape, so it is a good material for ground planting, potted plants and cut flowers. In order to prolong the flowering period of cornflower, spring sowing and summer sowing can be used in addition to autumn sowing. If it is sown from April to May, it will blossom from July to October of that year. Wait until July, sow with the mature seeds of that year, generally can blossom after September, if you cultivate corn chrysanthemum in open field, it can last to Frosts Descent. The ground-planted plants were transplanted into flowerpots in mid-late October to spend the winter, or sowed directly in the pot in August and entered the house before entering winter. As long as the room temperature is kept at 8 ℃ 15 min in winter, proper watering and a small amount of rarefied compound fertilizer can also make the cornflower blossom. This method of sowing in stages and batches can effectively prolong the flowering period of cornflower. Matters needing attention in cornflower culture, cornflower stems are thin and weak and are easy to lodge, so the planting distance should not be too dense. It is necessary to prevent overdense growth and poor ventilation. In the seedling stage, it is necessary to top and pick the heart to promote more branches and dwarf the plant, so that it blossoms more and the plant shape is beautiful. During the growing period, liquid fertilizer should be applied once every 20 days, but it should be noted that more nitrogen fertilizer should be applied, and more phosphorus and potassium fertilizer should be applied properly to make the stem firm and the flower color bright. At the same time, watering should be moderate, not too much, and we must pay attention to timely drainage in the rainy season, otherwise it will cause rotten roots and affect the normal growth of the plant.
