Detailed Explanation of the Key Cultivation Techniques for Edible Sunflower 363
Edible sunflower 363 has a well-developed root system and strong lodging resistance. It has a large flower head, a convex head, a 3-level inclination, and a high pollination seed-setting rate. Today we introduce the cultivation techniques for edible sunflower 363.
1. Land selection and preparation
Choose drip-irrigated land with medium-to-upper fertility; when preparing the land, use a driven harrow to achieve level ground, fine soil and good moisture, avoid continuous cropping, and achieve a 3-5 year rotation.
2. Seed treatment
For edible sunflower hybrids, the seed coating agent contains only fungicidal and nutritional components, with no insecticidal components. Do not be misled by the coating agent. In order to effectively prevent underground pests such as wireworms, cutworms and crickets, seed dressing treatment must be carried out before sowing.
3. Sowing at the right time
When sowing, avoid rainy weather to prevent soil crusting. If rainfall after sowing causes crusting, break it up promptly. Dig holes 2—3cm deep and cover with 2cm of soil. When machine sowing, adjust the machine in advance and check at all times whether the seed drop tube is blocked, so as to avoid missing plants and broken rows. Try to avoid the sowing method of dry sowing and wet emergence.
4. Fertilizer and water management
Water the first time in the middle of the bud stage, and it must be thoroughly watered to help the edible sunflower take root. The number of waterings should be determined according to soil conditions, soil moisture and rainfall. Stop watering in time at the maturity stage, otherwise the seeds will turn yellow. Apply fertilizer 3-4 times throughout the growth period. At the first bud-stage watering, apply 10 kg/mu of urea; at the second watering, apply 10 kg/mu of urea and 5 kg/mu of potassium fertilizer; at the flowering watering, apply another 5 kg/mu of urea and 5 kg/mu of potassium fertilizer; at the grain-filling watering, apply 5 kg of potassium fertilizer.
The above is the relevant introduction to the cultivation techniques for edible sunflower 363, and we hope it is helpful to everyone.
