What are the planting methods of sunflowers? And its planting conditions?

Sunflowers represent sunshine and hope, the flower of light, giving people a good sense of hope. Looking at the sunflower, I feel that life is full of faith and vitality. Imagine what a wonderful feeling it is to be full of sunflowers. When it comes to the planting method of sunflower, first of all, we have to consider its planting conditions, let's take a look!

I. planting conditions of sunflowers

1. Temperature: sunflowers facing the sun, like the sun very much. Sunflower seeds begin to sprout when the soil temperature is above 3 degrees. But it takes 6 degrees to take root and sprout. To maintain normal growth, you need to keep the temperature at 11 degrees.

2. Moisture: sunflower has strong heat resistance, so it has a great demand for water. Compared with corn, it requires twice as much moisture as corn. But in the whole growth process of sunflowers. The amount of water required for each growth stage is also different. The best solution for watering on demand.

3.Illumination: sunflowers grow toward the sun and are not afraid of sunlight. Even in the seedlings. Both the disk and the leaves yearn for light. The stems and leaves are luxuriant when there is plenty of sunshine. The rate of fruit will also increase. Sunflower seeds grow fuller. So choosing a place with plenty of light to grow sunflowers is a necessary condition.

4. Soil: sunflowers have relatively less strict requirements on soil. Because the root system is developed toward the sun. I like the sun and have strong resistance to drought. The ventilation performance of the rhizome of sunflower is also very good in the process of growth. It can be planted even in places with plenty of water.

Second, the planting method of sunflower

1. Land selection and preparation

Although sunflowers do not require so much soil. But it is necessary to choose a good piece of soil to plant. From the point of view of soil type, either clay or light sandy soil is OK, but its acid and alkali resistance is 5.5-8.5. If the acid-base performance is too large, it will affect the growth of sunflowers.

Flat land with relatively deep soil layers is needed. When repairing the land, it should be done in detail. The hard soil needs to be broken. The stones need to be removed. When sowing, the new high-fat membrane can be stirred evenly. This prevents pests. Increase the germination rate.

2. Seed selection treatment

When you choose a seed, you must choose a good variety. It grows faster this way. The ability to resist the virus is also stronger. From the appearance, the particles need to be full. The color is good. After selecting the seeds, expose them to the sun for 2-3 days, and remember to turn them in time. At the same time, attention should be paid to disinfecting the seeds.

3. Sowing time

The temperature in March and April is 1926 degrees, which is the most suitable time to sow seeds. However, some varieties that have requirements for the season can be considered according to the actual situation. After sowing for 6-8 days, it can sprout.

4. Check the fields and replenish the seedlings

Sunflower belongs to a dicotyledonous crop, if you encounter overcast and rainy weather when breaking the soil and coming out of the shell. If the soil is consolidated, it will not grow. Therefore, it is necessary to replenish the seedlings, and those that do not grow should be replenished.

5. The seedlings are fixed

If the sunflower seedling is too dense, it will affect its growth, so the need for inter-seedling also needs to be fixed.

6. Ploughing and weeding: soil planking will affect the growth of sunflowers. So it is important to loosen the soil. Ploughing and weeding should be done once when two true leaves are grown, and once again a week after the seedlings are fixed. We have to plough and weed again before sealing the ridges. At the same time, it also needs to fertilize, cultivate soil and open ditches.
