Buckwheat head planting

1. Cultivation season

In the southern part of the Jiangnan region, generally in mid-August to early September sowing. Sowed too early, high ground temperature, rainfall, seed Sheng easy to rot; too late, the growing period is short, reducing yield.

2. Sowing

Before sowing, each hectare of well rotted organic fertilizer 45000 ~ 60000 kg, deep turning, harrowing. Then make a small raised bed 2~2.5 meters wide. Allium is mostly propagated by bulbs. Before sowing, choose neatly shaped, fat bulbs with few tillers and no rotting or deteriorating bulbs for seed. Eliminate the small, rotting, disabled. Seed bulbs to remove dry leaves, cut off the long roots, retaining 1.6 centimeters long.

In the raised beds according to the row spacing of 25 centimeters open ditch, ditch depth of 8 ~ 10 cm. When planting, if 1 seed per hole, hole spacing 7~8 cm; if 2~3 seeds per hole, hole spacing 15~16 cm. After planting, cover with a thin layer of soil to slightly expose the top of the stubble stalk. After planting the whole bed, spread a thin layer of grass, while pouring a layer of rotting stable fertilizer, about 15000 kg per hectare.

3. Field management

After the emergence of seedlings began to chase the fertilizer, every 15 ~ 20 days once, each time per hectare after the rotted human urine 15000 kg, or 225 ~ 300 kg of compound fertilizer. Until the next year's pre-harvest help days. Growing period often keep the soil moist, no rain 3~5 days a water. Pay attention to drainage after heavy rain to prevent long-term flooding.
