苜蓿 Cultivation Techniques

1. Apply base fertilizer: Alfalfa has a large demand for phosphate fertilizer and potash fertilizer. Apply 1000 kg/mu of organic fertilizer, 20–30 kg/mu of phosphoric acid diamine, and 3–5 kg/mu of urea as base fertilizer before planting.
2. Site preparation: Deep plowing is required, and the depth of ploughing is 25 cm or more. Before the broadcast, it will be ready for broadcast without any rubbish, no weeds, good lyrical condition, no imaginary reality, and smooth surface.
3, sowing: can be sowed before the beginning of August. Drill or broadcast. The drilling distance is 20-40 cm, the seeding volume is 0.8-1 kg/mu, the seeding depth is 1-1.5 cm, and no more than 2 cm. Repression after sowing. Water once after sowing. Watering once every 7 days after emergence, evenly pouring 3 times to ensure full seedlings.
4. Weeding: Remove weeds after emergence. Manual weeding 1 or 2 times. Chemical control of grass. Before sowing, soil closure with Alachlor or trifluralin, 43% Alachlor EC 260-300 ml/mu, and 48% Triflura EC 80-100 ml/mu.
5, watering: watering each castration. The whole growth period irrigation 3 to 4 times. Anti-water.
6, dressing: the first year of rhizobial bacteria has not yet fully formed, need to apply urea 2 to 3 times, each time 3 to 5 kg / acre.
7, disease prevention and control: mainly downy mildew, powdery mildew, rust and so on. 70% thiophanate-methyl 1000-fold spray; 15% triadimefon 1000-fold spray; 75% chlorothalonil spray 600 to 800 times; 80% dexamethasone wettable powder 500 times spray.
8. Harvesting: The best cutting period is between budding and early flowering. Keep the height of 4 to 5 cm. The last cutting time should be 30 to 40 days before cessation of growth, leaving 5 to 10 cm.
