Detailed Explanation of Super-High-Yield Cultivation Techniques for Single-Season Rice in Northern China
(1) Use plastic film and special non-woven fabric to cover dry-raised rice seedlings, with the seeding rate controlled within 200 grams per sq m. (2) Transplanting spacing in the paddy field: 30 cm x 16.7 cm to 20.0 cm sparse planting, or (40 cm + 20 cm) x 16.7 cm wide-ridge double-row sparse planting. (3) Apply 60-70 kg of standard nitrogen per mu, 10 kg of diammonium phosphate, and 10 kg of potassium sulfate. (4) Intermittent water-saving irrigation in the paddy field alternating shallow water, wet, and dry conditions. (5
