Oil sunflower planting prospects

1. Oil sunflower planting cost

  Oil sunflower seeds are generally 30 yuan per catty. Planting about 5 catties of seeds per mu of land, and later fertilization and pesticide application, etc., costs about 500 yuan per mu of land, 20 yuan for sowing, 100 yuan for fertilizer, and 70 yuan for irrigation. The profit of one mu of oil sunflower is 1450-2650 yuan. Each mu of land can produce 700-800 catties of oil sunflowers, which can be sold for 3-4 yuan per catty, with a profit of 2100-3200 yuan, so the net profit after deducting the cost is 1450-2650 yuan.

2. Prospects of oil sunflower cultivation

  Sunflower is easy to grow, has good benefits, is widely used, and is a healthy trend. The oil extracted from sunflower is a recognized health oil and healthy oil. It is recognized and loved by everyone and is extremely beneficial to everyone's health. Moreover, sunflower is not a difficult crop to grow and maintain, and it has a strong ability to adapt to the environment.

It can also grow normally in arid and barren areas, which means it has no geographical environmental restrictions and there is no need to worry about planting failure after investment, so the prospects for planting sunflowers are still good.

How to grow oil sunflower with high yield

1. Seed selection: Use excellent varieties of oil sunflower, which should have high yield, good stability and excellent quality.

2. Land preparation needs to be meticulous: Land preparation is often a key factor in determining crop growth. Land preparation for oil sunflowers must be meticulous. Before sowing, deep plowing should be done about 23 cm, the ground should be harrowed and leveled evenly, and appropriate amounts of fertilizer should be applied according to soil conditions.

3. The sowing time should be appropriate: Spring sowing of oil sunflower can be carried out from March to early April, and sowing with mulch covering can be carried out half a month in advance. Summer sowing is in June-July. Spot sowing is the best sowing method, with 2 seeds placed in each hole. The spacing between rows of oil sunflower plants should also be appropriate.

4. Pruning branches and assisted pollination: When the flowers begin to bloom, remove the excess branches and leaves of the oil sunflower in time to promote the growth of the main stem flower disk. Artificial assisted pollination can increase the seed setting rate of oil sunflowers more than insect pollination.

5. Fertilizer and water management: Combine inter-row cultivation, weeding and thinning when there are three pairs of true leaves. Combine watering with 5 kg of urea per mu during the bud stage. During the flowering and filling periods, spray urea solution or diamine solution on the leaves.

6. Pest and disease control: Borers should be sprayed with insecticide during the budding period and after flowering and pollination. Do not spray pesticides within 15 days of flowering and flower withering to avoid killing bees and other insects and causing poor pollination.
