To make flat and smooth, 1.5 meters and 8 meters of flat rice, 5 to 7 kg of rotten chicken or pig manure per square meter, 8 kg of humic acid eco-fertilizer and 0.1 kg of urea. Line net 0.05 kg, 50% carbendazim WP 0.02 kg, soil and fertilizer mix, leveling.

Washed with water 2 times. 60% of the radicles are sown immediately when they are extended.
3. Seeding: spring sowing leek in early April to mid-April, the ground temperature is stable above 12 °C, the daily average temperature of 15 ~ 18 °C can be sown. Using drilling, seedlings per acre with 6 to 8 kg of dried seeds, can plant 6,000 square meters of vegetable fields, immediately after the film is covered with plastic film, insulation temperature. 70% of the seedlings were uncovered in the top soil.
4. Seed management: watering and fertilizing. Qi Miao until the seedling height of 16 cm, according to the flood season 7 to 10 days watering time, combined with watering, per acre red rot of human fecal urine or humic acid 50 kg. Before sowing, use 33% of Shi Tianbu 250 times liquid sprayed on the surface after emergence, artificially weeding 2 or 3 times.
Colonization
1. Timely colonization: general plants up to 18 to 20 centimeters have not been divided, colonization after the summer solstice.
2. Deep plowing and fertilization: After cultivating the medlar in front of the plant, plowing 20 centimeters deep and applying it into the mature quality circle per acre.
