Field management of sunflower

Golden sunflower is a kind of edible plant with very high nutritional value. It is also the most edible and medicinal variety among more than 200 okra plants. In China's market is relatively large, planting sunflower is relatively simple, but we need to do a good job in field management. There are also many people who fail to plant because of poor management. So how do you manage the cultivation of sunflower? Let's take a look at it together with Xiaobian below!

1. Timely topdressing

The plants of sunflower are relatively large, with strong growth ability, and the demand for nutrients in the growth process is relatively large. Therefore, we should apply sufficient base fertilizer when planting, and also do a good job of topdressing. The base fertilizer is mainly decomposed farm manure, and then topdressing should be done at least twice during the growth period, especially during the flowering period. And every harvest to chase a fertilizer, supplement due to harvest and loss of nutrients.

2. Reasonable watering

As mentioned earlier, the plants of sunflower were large and their leaves were plump, so their demand for water was also relatively large. Water at least twice during the seedling stage of the sunflower. When it reaches the flowering stage, the water demand rises, so water frequently to keep the soil moist. In summer, when the weather is hot, it is also the harvest season of golden sunflower, this time should be kept regular watering. However, water should not be too much, encounter rainy days or excessive watering, to timely drainage, to prevent excessive water caused by waterlogging dead seedlings.

3. Cultivation

Sunflower root ability is relatively strong, so we plant in order to promote the development of sunflower roots, at least two times before the bud stage of the plant to carry out more than two times of cultivation work. And after flowering, we should also do a good job of intertillage. Proper intertillage can not only prevent soil hardening, affect root respiration and nutrient absorption, but also achieve the purpose of weeding and prevent grass shortage. Finally, soil cultivation should be done well before sealing the rows to improve the lodging resistance of sunflower.

4. Plant adjustment

In order to improve the permeability of the field, pruning should be done when the plants are too lush. Cut off the lateral branches at the base of the plant in time, and thin out the aged and yellow leaves. If there is excess nutrition, twist the leaves properly and bend the petioles to prevent excessive vegetative growth. Then in the middle and later stages, the old leaves should be removed in time to reduce nutrient consumption and reduce the incidence of diseases and insect pests.

5, pest control

The disease resistance ability of sunflower is relatively strong, the incidence of disease is low, but the occurrence of pests is more. Different pests appear at different stages of growth, such as aphids and borers, which are more harmful during seedling and flowering stages. Therefore, we should strengthen the prevention and control of diseases and insect pests, avoid crop rotation, improve the disease resistance of seedlings, deep tillage, rational fertilization and so on. Then use light trap, artificial killing method to eliminate pests, serious when the rational use of chemicals for prevention and control.

The growth period of sunflower is about 3 months, and the harvest period can also reach 3 months. Therefore, attention should be paid to nutrition supplement when harvesting to prevent insufficient nutrition from affecting subsequent harvest and reducing planting efficiency.
