First, choose good breeds. Good selection of locally grown hybrid generation seeds with good yield, high oil yield, and strong disease resistance, such as the United States short large head 567DW, 667DW and so on.
Second, the election and site preparation
1, the election. You should avoid heavy tricks and pay attention to rotation. Continuous crop disease is serious, the plant is short, the flower disk is small, and it is prone to premature aging, and there are many empty grains, which can reduce the yield by 5-20%.
2, site preparation. Deep-spotting the land preparation and timely protection. Dip 20-25cm deep before planting. According to the conditions of fertility, 2-3 square meters per acre Shinongjiafu, 20-25 kg of superphosphate, 10-15 kg of ammonium bicarbonate, 10-15 kg of potassium sulfate. Or Mushi Sanyuan compound fertilizer 30-40 kg.
3, timely broadcast. The oil sunflower is very resistant to low temperature and should be sown as early as possible under the condition of ensuring seedling emergence. Plastic film coverage was performed in early March (before and after convulsions). Bare sowing dates from late March to early April, summer sowing in late June to early July. Plants are generally planted at equal intervals, with a 60-foot row spacing and a 30-33 inch spacing. According to soil conditions, suitable soil density is 3300-3500 plants/mu, suitable soil density is 3500-3800 plants/mu, and sowing method is better. The on-demand seed amount is 400-500 grams per mu. The sowing should not be too deep. Generally, it should be controlled at 3-5? When the sensation is good, the seeding depth should be 3cm; when the sensation is good, the seeding depth should be 5cm. Poor soil moisture can be sown.
