First, the soil anti-freezing is poor in the quality of the whole field, and the large root loquat seedlings can be soil-fertilized for soil anti-freezing and seedling protection.
2. Water and fertilizer management Early watering Early watering should be applied to wheat fields with frozen leaves and young ears, so as to prevent dehydration of young ears.
Topdressing nitrogen fertilizer should be applied to the frozen wheat fields with young ears. Accelerate nitrogen fertilizer. Apply 10-13kg of ammonium nitrate or 20-30kg of ammonium bicarbonate per mu. Combined with watering, ploughing and loosening the soil to restore frozen wheat seedlings as soon as possible. Grow.
Increasing application of phosphate fertilizer can promote tillering and root growth. For phosphate-deficient wheat fields, urea and diammonium phosphate can be mixedly applied.
3. Spraying growth regulators When wheat plants are frost-damaged during the wintering period, spraying wheat seedlings with a solution of 0.3% -0.5% chlormequat solution can inhibit plant growth, resist or reduce the occurrence of frost-damage. In addition, spray the "new high-fat film" emulsion 800 times, once every ten days or so, to prevent freezing, cold, and restore the physiological vitality of wheat.
