High-yielding Cultivation Techniques of Spring Wheat
Here is a revised and improved version of the original text in English, written in a natural, human-like style with added content to meet the 500-character minimum:

1. **Soil Preparation, Hoeing, and Fertilizer Application**
(1) **Site Preparation**: To ensure timely planting of seedlings in early spring, it's essential to apply agricultural fertilizers before winter. The soil should be well-tilled, fine, and free of weeds. This creates an ideal environment for healthy growth.
(2) **Field Layout**: For irrigated plots, the layout must match the canal system to ensure efficient water distribution. Typical dimensions are 1.2–1.3 meters wide and 20–40 meters long. Adjustments should be made based on land topography to ensure even irrigation.
(3) **Fertilizer Application**: Apply more than 3,000 kg of high-quality fertilizer per mu. Mix it thoroughly and perform continuous tilling to ensure even distribution.
(4) **Winter Irrigation**: During the period from the beginning of winter to the small snow, each mu should receive about 80 cubic meters of water. The upper soil layer should have 17–18% moisture, while the lower layer should contain around 20%.
2. **Selecting Quality Seeds and Seed Treatment**
Choose dwarf-resistant varieties for irrigated land and drought-tolerant ones for dry areas. Use wind or screen selection, or use saltwater (18–20%) to remove weak seeds. After selecting, dry the seeds properly before sowing.
Soak seeds 7–10 days before planting under sunlight for 2–3 days to dry them slightly. This helps reduce pests and improves germination rates.
Treat seeds with chemicals to prevent disease and conduct a germination test before planting.
3. **Timely Sowing and Improving Seedling Quality**
The optimal time for spring wheat planting in our province is between March 10 and 25, once the soil is thawed to a depth of 5 cm. If the weather is delayed, plant early to avoid cold damage. Avoid planting in April if possible.
Seed rate should be at least 400,000–450,000 plants per mu for irrigated fields, and around 350,000 for dry land, with approximately 20–22 kg per mu. Ensure proper spacing (25–20 cm) and sowing depth (3–4 cm). Use machine seeding to ensure even distribution and press the soil after sowing to promote strong seedlings.
4. **Scientific Fertilization**
If no fertilizer was applied during soil preparation, add 1,000 kg of high-quality fertilizer at sowing. Apply 10–15 kg of diammonium phosphate or 25–30 kg of compound fertilizer per mu. At the 2-leaf stage, apply 50–60 kg of nitrogen. During the booting stage, apply 10–15 kg of nitrogen. Spray 0.2–0.3% dipotassium phosphate or 1% urea solution (50 kg per mu) 1–3 times during the booting to flowering stages to improve leaf function and grain weight.
5. **Timely Irrigation**
In arid regions, spring wheat requires 4–5 irrigations during dry periods. The first irrigation occurs at the 2-leaf stage, followed by jointing, booting, and grain-filling stages. The final irrigation, known as "yellow water," is done just before maturity to improve microclimate and prevent heat stress.
After heading, avoid overwatering to prevent lodging. Watering should be done carefully, especially on windy days.
6. **Field Management**
Thinning seedlings when they have 2–4 leaves can help strengthen the crop. Press young seedlings 1–2 times to promote root development and tillering. Use chemical weed control and apply CCC (Chlormequat Chloride) to prevent lodging in dense or weak crops. Drain excess water before the grain-filling stage to avoid root rot.
7. **Timely Harvest**
The best time to harvest is during the wax ripening stage, when grains have maximum dry matter and flour quality is at its peak. Harvesting too late leads to nutrient loss and weak straw. Combine this with the rainy season, so quick harvesting and threshing are crucial to maintain yield and quality.
