Detailed Tutorial on High-Yield Sunflower Cultivation Techniques and Methods

Sunflowers not only have high edible value, but are also a very important oil crop, and their flower language is also very meaningful. Sunflowers represent “silent love, loyalty”, and their ornamental value is also very high. Fields upon fields of sunflowers make people feel relaxed and happy. But most people grow them to make money, and to improve their own economic benefits, they need to increase sunflower yields. So how should sunflowers be planted to achieve high yields? Let's take a look together below!

1. Land selection

Sunflowers are not very strict about soil requirements and have strong adaptability. They can quickly adapt to soil pH, moisture and fertility. However, they are still not suitable for planting on land prone to waterlogging where standing water is difficult to drain away. Fertile soil can also allow sunflowers to grow better, which is conducive to increasing sunflower yields and raising the oil content of sunflowers. Therefore, when selecting land, we should try to choose plots with deep, loose soil and strong fertilizer and water retention.

2. Sowing

Choose excellent varieties. For example, varieties such as Hungarian No. 4 have the advantages of good disease resistance and lodging resistance. However, we must decide the sowing time according to factors such as different varieties and soil fertility. For example, Hungarian No. 4 should have its sowing time appropriately delayed. This is because doing so can effectively increase yield, reduce the phenomenon of empty seeds, and also lower the incidence of pests and diseases, providing a good growing environment for sunflowers.

3. Weeding

About three weeks after sunflower seedlings emerge, field management should be carried out promptly, and work such as thinning and spacing seedlings should be done well. But as the seedlings grow, weeds will also begin to grow rampantly, so timely weeding must be carried out to prevent too many weeds from growing. This is because too many weeds will compete with the seedlings for nutrients, affecting seedling growth. Proper weeding can also promote root growth and enhance nutrient absorption. Be careful not to damage the roots when weeding, which would produce the opposite effect.

4. Pruning branches

Different sunflower varieties have different growth patterns, but all have the characteristic of branching. Sunflowers have a strong branching ability. Although branches can grow flower discs, they will compete with the flower disc on the main stem for nutrients. The harm is the same as that of weeds, causing poor nutrition in the main stem's flower disc, preventing the flower disc from expanding, and increasing the phenomenon of empty seeds. Therefore, during the flowering period, we should remove all excess branches. The plant only needs to keep the flower disc on the main stem to ensure nutrient absorption and growth and development of the main stem's flower disc.

5. Pollination

Sunflower flowers are divided into male and female flowers. Usually pollination is carried out by insects such as bees, but this pollination method has a high probability of failure and increases the chance of empty shells. Therefore, we should carry out artificial pollination or keep an appropriate number of bees for pollination. After sunflowers bloom, rubbing adjacent flower discs face to face against each other can achieve the purpose of pollination. Doing this about 3 times is enough. Try to choose the morning for pollination, which can improve pollination and reduce empty seeds.

The above are the high-yield cultivation techniques for sunflowers. To obtain high-yield sunflowers, management needs to be strengthened. The things that need to be done during the cultivation process are certainly not limited to these aspects mentioned above. More places still require everyone's careful observation. Many small details are overlooked by us, which is why in many cases we fail to reach our ideal yield. That is all for today's introduction.
