The latest course of high-yield cultivation techniques of sunflower

Sunflower not only has a high edible value, but also a very important oil crop, its flower language is also very meaningful. Sunflower represents "silent love, loyalty", the ornamental value is also very high, a piece of sunflower field makes people relaxed and happy. But most of them are planted in order to make money, and if you want to improve your own economic interests, you have to increase the output of sunflowers. So how can sunflowers be planted in order to produce high yields? Let's take a look at it with the editor.

1. Select the place

Sunflower is not strict to the soil, has a strong adaptability, to the soil PH value, moisture and fertility can quickly adapt. However, it is still not suitable to plant on the land where waterlogging is easy to occur and the stagnant water is not easy to discharge. And the fertile soil can make the sunflower grow better, which is beneficial to the increase of sunflower yield and the increase of sunflower oil content. So when we choose the land, we try to choose the land with deep and soft soil layer and strong water retention and fertilizer retention.

2. Sowing seeds

The selection of excellent varieties, such as Hungary No. 4, has the advantages of good disease resistance and lodging resistance. However, we have to decide the sowing time according to the different varieties, the fertility of the soil and other factors. For example, Hungary No. 4 should appropriately delay the sowing time. Because this can effectively increase the yield, reduce the phenomenon of empty grains, but also reduce the incidence of diseases and insect pests, and provide a good growth environment for sunflowers.

3. Weeding

When sunflower seedlings emerge about three weeks after the timely field management, do a good job of seedling thinning and other work. However, with the growth of seedlings, weeds will also begin to grow, so it is necessary to weed them in time to prevent weeds from growing too much. Because too many weeds will rob the seedlings of nutrients, so that the growth of seedlings is affected. Proper weeding can also promote root growth, enhance nutrition absorption, pay attention to weeding do not hurt the root, play the opposite effect.

4. Cross

Different sunflower varieties will have different growth patterns, but they all have branching characteristics. The branch growth ability of sunflower is strong, although the branch can grow disk, but it will compete with the disk on the main branch for nutrients, the harm is the same, resulting in the main branch disk malnutrition, disk can not expand, empty grain phenomenon increased. Therefore, when we are in flowering, we should wipe out all the excess branches and keep the disk on the main branch immediately to ensure the nutrition absorption and growth and development of the disk.

5. Pollination

Sunflower flowers are divided into male and female flowers, usually pollinated by bees and other insects for pollination, but this method of pollination will have a high probability of failure, increasing the chance of empty shell. So we have to carry out artificial pollination or raise the right number of bees for pollination. After the sunflower blossoms, the adjacent disk faces can be rubbed against each other to achieve the purpose of pollination, about 3 times, pollination time as far as possible in the morning, can improve pollination and reduce empty grains.

These are the high-yielding planting techniques of sunflowers. If you want to get high-yielding sunflowers, you need to strengthen management. The things that need to be done in the planting process are definitely not only the aspects mentioned by the editor, but also need to be carefully observed in more places. Many small details have been ignored by us, so very often we can not achieve our ideal output. That's all for today's introduction. If you want to know more about it, please continue to follow us!
