Sunflower cultivation, sunflower cultivation techniques

How to grow sunflowers.

Every time the sunflower is cultivated, the seeds can first be germinated, and then prepare the soil with high fertility and can help drain the water in time.

The seeds of sunflowers are very large, and the survival rate of planting is very high, but if the seeds of sunflowers are soaked in water for 6 hours, or soaked in carbendazim and rooting water for 5 15 minutes, this can prevent the seeds of sunflowers from suffering from diseases and insects during the sowing process. It's good to keep your eyes open.

Sunflower drought tolerance is relatively strong, and its roots are also more developed, to provide it with the need to prepare fertile soil, it is best to discharge the water in the soil in time, so as to make it grow better, generally can be used humus mixed with garden soil can be used as sunflower cultivation substrate.

In fact, the sunflower cultivation technology is very simple, sow the seeds of the sunflower into the soil, wait for a period of time after the seeds will germinate, and then water and fertilize it, in the process of sunflower germination, it needs to be placed under astigmatism care, and after germination, it needs to be placed in full sunlight.

When cultivating sunflowers, only 2 or 3 seeds can be sown in a pot, when the seeds germinate if they are not transplanted in pots, then it will affect their normal growth, usually after germination and breeding for one month, the smaller seedlings will be separated into the new potting soil, and fertilizer will be applied to the soil, which can make the seedlings grow rapidly. Hayamori.

Sunflower planting temperature is stable above 18 degrees and then sowing and cultivatingGenerally speaking, it is best to sow seeds at the end of April or early May, and if you sow now, it must be a little late, but if you sow seeds in the south, it doesn't matter if you sow seeds in summer and autumn in a place where there is no frost all year round.

Precautions for sunflower plantingSunflowers should be properly watered during the flowering period, and the rainy days should be drained in time, so that there is no drought or waterlogging, and too much water should be avoided, because it is easy to cause the plant to rot roots, and if it is not treated in time, it is easy to cause the plant to die, so we should pay more attention to it.

In the process of breeding sunflowers, people should pay attention to pests and diseases, because for any plant, the threat of pests and diseases is more serious, and it is necessary to prevent it appropriately, so in the process of breeding, it is necessary to spray insecticides or pesticides appropriately, so as to avoid the occurrence of fierce pests and diseases.

If you want to grow sunflowers, you can sow seeds between March and April in the spring. After the loose and fertile land is turned over, the seeds of sunflowers can be sown in the soil. After sowing, it is necessary to water the right amount, during the maintenance period, it is necessary to keep the soil moist, stabilize the temperature between 18 and 25 degrees, and generally after 5 7 days, the seeds of sunflowers will germinate.

The main propagation method of sunflower is sowing propagation, which is suitable for spring between March and April. Before planting, it is necessary to choose land with soft, breathable and easy drainage. Before sowing, it is necessary to loosen the land and weed, apply an appropriate amount of basal fertilizer, sow sunflower seeds in the soil, and water it appropriately.

During the curing period, the temperature of the environment should be stabilized between 18 and 25 degrees, and the soil should be kept moist. Under the conditions of suitable temperature and sufficient soil moisture, the seeds can germinate after 5 to 7 days. After the seeds germinate, they should be given sufficient light and water to make them grow better, and it is also conducive to the growth of leaves.

In the later stage, after the sunflower grows leaves, it can be supplemented with fertilizer, which is mainly nitrogen fertilizer, which can promote the growth of young leaves. During the maintenance period, reasonable maintenance should be carried out according to the growth habits of sunflowers. Sunflowers love light and should be given plenty of light, but the light is too strong in summer, so they need to be shaded.

Sunflowers need water during their growth, but they are not waterlogging tolerant and need to be watered in moderation. During the maintenance period, it is necessary to carry out reasonable irrigation, and it is necessary to increase the amount of watering for the flowers to grow before the flowering period. During the growth period, nitrogen fertilizer is the main fertilizer in the initial stage, and phosphorus and potassium fertilizer is mainly used before the flowering and fruiting stage, which is conducive to the growth of flowers and fruits.

Summary. Hello, dear. The method of planting sunflowers: planting time, choose to sow in March and April in spring to facilitate the germination of middle branches; In the germination process, the selected seeds are soaked to absorb water, and sown after being exposed.

Hello, dear. The method of planting sunflower row wheel in the tung type: planting time, choose to sow in March and April in spring to facilitate the germination of middle branches; Germination treatment, the selected seeds are soaked to absorb the water stalls, and the seeds are sown after being exposed.

1. There are many varieties of sunflower seeds, and you can choose the right excellent varieties according to your own needs and environmental conditions. Once you have decided on a good variety, you can go to a specialized seed store to buy good seeds. 2. Before sowing seeds, you can also do not treat the potato tremor, but in order to improve the germination rate, it is best to soak the seeds in warm water for a while in advance, so as to promote germination by absorbing water.

3. Soil selection of sunflowers should be counted before sowing and planting, and the soil should be sorted out first. If it is planted on the ground, it can be selected in a sunny place, and the place where the land is flat, the soil is loose, the fertility is medium, and the drainage is convenient, and the soil should be leveled in advance. You can also use the seedling tray to raise seedlings, prepare the appropriate size seedling tray, and prepare the soil to fill the seedling tray.

4. Sowing seedlings Sunflower is suitable for sowing seedlings in a suitable environment, and maintaining the temperature can promote the germination of seeds as soon as possible, and the time can be selected in about 3-4 months in spring. Once the soil is leveled, sunflower seeds are sown on the surface of the soil and covered with a thin layer of soil. After sowing, keep the temperature good, water properly to keep it moist, and keep it in a sunny place, and it will germinate and grow after about 3-4 days.

5. Transplanting plantingWhen the seedlings grow a few true leaves, they can be transplanted and planted, determine the planting place, take out the sunflower seedlings, and then transplant them to the soil, and water enough root water to promote rooting.
