1, chestnut seed germination does not require special treatment, the key is to pay attention to winter storage, generally take sand storage, is the sand and chestnut seeds, 1:2 mix, and then in the winter does not waterlogged place digging pits, put it in the top of the mulch 40 centimeters, the best in the cover straw insulation, in the spring 3-4 months when sowing take out, sieve out the seeds.

2, sowing seeds to take monopoly sowing, on the ridge with a stiletto open ditch 10 cm wide, 10 cm deep, scattered bottom fertilizer, generally use diammonium or composite fertilizer, and then step on the foot to flatten, in the ditch cloth seed, twenty centimeters away, the seed is placed flat, the top mulch 5 cm, compaction can be.

3, pay attention to just sowing to keep the soil moist, selected to do the seed of chestnut is best to use 50-60 heads per catty, the seed is too small out of the seedlings will not be strong, 50 heads of seed in general that year the seedling rate can be more than 95, a seedling can be more than 60.
