Sunflower planting techniques and matters needing attention

Sunflowers are loved by the majority of flower friends because of their large and colorful flowers and continuous blooming. Sunflowers bloom in the morning, evening and cloudy days, so they are also known as sunflowers and noon flowers. Today, the editor will talk about how to raise sunflowers. And matters needing attention for breeding sunflowers?

I. Culture methods of sunflowers

1. The best time to reproduce

The best sowing and propagation time of sunflower is in spring, summer and autumn.

2. The best growing soil.

Sunflowers are OK for poor and thin soil or general soil, of course, it is best to choose sandy soil with good drainage to propagate.

3. Growth temperature and humidity requirements

The amount of water should not be too much, just keep the soil slightly moist, take good drainage measures to prevent stagnant water; when sprouting, the temperature should be controlled at 21-24 degrees, about 7-10 will emerge, because the seedlings are relatively weak, so it is necessary to maintain a higher temperature, which is conducive to the rapid growth of seedlings and the formation of sturdy, fleshy branches and leaves.

4. The best growth light

Sunflowers are more like warm, sunny environment of the potted plants, so to ensure that enough light time, in the display, do not put in a wet place without light.

Matters needing attention in cultivating sunflowers

1. Spread fertilizer

Because sunflowers do not have high requirements for fertilizer, sunflowers are easy to deal with at the point of fertilization. Applying 0.1% potassium dihydrogen phosphate every half a month can make sunflowers bright and blooming.

2. Watering key points

A. growth stage: no frequent watering is required.

B, seedling stage: if the weather is not very hot, and the amount of water evaporation is small, you can not pour too much water.

C, flowering period: because the flowering period is in three days, the weather is hot and the water evaporation is large, so when watering, it needs to be watered thoroughly and fully absorbed.

3. Pruning essentials

In the seedling 3-4cm, cut off the tip of the main branch, soon the wound will grow new shoots, wait until the root branch grows to a certain length, it is also possible to cut off the branch tip, so that the sunflower plant shape becomes more beautiful.

4. Replacement of basin soil

A, base fertilizer: when moving the basin, you should first make the base fertilizer. You can use the expired sesame meal and fish intestines (fermented) as the base fertilizer.

B, culture soil: 3 parts of pastoral mature soil, 5 parts of yellow sand, 2 parts of rice chaff ash or fine sawdust, and then mix evenly with a little calcium superphosphate powder.

5. Main points of reproduction

A, sowing seeds

When sowing, it is best to choose when the temperature is above 20 degrees, cover with thin soil after sowing, and it will germinate after ten days. When the seedlings are planted, each plant is planted at a distance of 5 × 6cm, and liquid fertilizer is applied regularly. Under the growth environment of 15 degrees, it will blossom in about 20 days.

B, cuttage propagation

Choose double variety, in summer, the cut branches will be used as cuttings, and buds will appear after cutting and propagation. When cutting and transplanting, there is no need to carry soil with the plant, and the fruit will crack when it is ripe. At this time, the seeds are easy to fall, so it is necessary to harvest in time.

6. Disease and pest control

A, aphids

It mainly occurs before germination, so imidacloprid 4000 × 5000 times can be used during flower bud expansion period. After germination, imidacloprid 4000 × 5000 times and cypermethrin 2000 × 3000 times can be used to kill aphids, and aphids can be used 1500 times after fruit setting.

B. Coccinellidae

Before germination and in late May, 50-80 times of cloth oil emulsion was sprayed and 1500 times of Tilesbon was added.

Third, the experience of cultivating sunflowers

1. Seedlings overwintering

After Frosts Descent's solar terms, sunflowers need to be moved into the room where there is sunshine. After the Qingming Festival in the second year, sunflowers can be placed outside the window. If there is a lower temperature, sunflowers can be moved into the window for maintenance.

2. Peacetime maintenance

Although not often watering, but to maintain a certain degree of humidity, apply 0.1% potassium dihydrogen phosphate every half a month.

The planting method of Camellia

--

① cuttage: in the dry season from May to June, select the young mother tree, cut one-year-old twigs from the top, about 10cm, remove the lower leaves, flatten the lower leaves with a blade at the bottom of the node, keep one lateral bud at the top, and insert 2-3 leaves into the medium of river sand or gravel. After insertion, cover up the grass curtain to shade, enhance the foliar spray, adhere to the air humidity of the bed, and promote rooting. In order to improve the survival rate of cuttings, cuttings can be soaked in 50~100ppm 's ABT rooting powder solution for 8 hours and 12 hours.

② grafting: choose strong seedlings or camellia species that can easily survive by cutting as rootstocks, truncate at the ground diameter 4~5cm, split about 1.5cm deep through the pith, use 1-2-year-old branches as scions, keep 1-2 leaves in the upper part of the scion, cut into wedges in the lower part, and stab into the split of the rootstock, and the constituent layers on both sides should be closely joined, and then tied tightly with plastic belt.

After grafting, cover the scion with a plastic bag and tie it with a belt below, but not too tight, so as to form water droplets in the bag and drop on the rootstock from time to time. Add a packing paper bag to the outside of the plastic bag to cover the direct sunlight.

③ bud insertion: take each bud node as a segment, save a leaf, about 1.5cm, cut the lower part oblique, and then stab it into the medium, the depth is to cover the branches. This method can make full use of branches and is suitable for many reproductive needs.

④ potted plant: when potted Jinhua tea is planted, it is appropriate to choose rotten leaf soil or peat soil plus part of garden soil and river sand to prepare culture soil. In order to make it grow rapidly. It should be planted in a well-breathable tile basin. When planting, it is best to choose a deep and simple basin, first fill a layer of broken tiles at the bottom of the basin to facilitate drainage; then apply a small amount of rotten cooked cake fertilizer or bone powder as base fertilizer, and fill a layer of culture soil above the fertilizer; then put the seedlings into the center of the basin and fill them layer by layer into the culture soil layer by layer, fill them layer by layer while compacting, and finally leave about the first centimeter of the basin edge. After planting, it was watered and cultured in a semi-shady place, and the seedlings were slowed down and transferred to normal management. Conclusion: Golden scented tea has the laudatory name of "tea queen" and "giant panda in the plant world". It is called "imaginary yellow camellia" abroad, with drooping pedicels, beautiful shape, thick waxy petals, golden color, long flowering period and high ornamental value. it is an ideal garden tree species for greening and beautification of courtyards and parks in tropical and subtropical areas. it not only has high ornamental value, but also has high medicinal value.
