Planting techniques of autumn potato

Planting autumn potatoes in autumn has the advantages of short production time, fast harvest and good benefit, so we must grasp the following technologies.

First, soil preparation and fertilization. Choose the land or field of loose sandy soil and sandy loam for planting. First use farm manure, human dung or fermented cake fertilizer as base fertilizer, sprinkle it on the ground, and then plough and flatten the box, which is 1 meter wide and 1.3 meters wide.

Second, accelerate germination and sow seeds. Choose non-rotten, egg-sized potatoes as seeds, cut horizontally into 4-6 pieces, each with budding eyes. After the seed block is cut, wash it lightly with cold water, dry it, mix it with a small amount of plant ash, and pile it in an indoor ventilated and cool place to sprout. When stacking, plant a layer of sand. After 10 days, the seed sprouted and spit root. When the bud grows to 1.5 cm, it can be sown. Sprout in the first ten days of October and sow in the middle and late ten days. Sowing according to 15 cm × 25 cm to dig holes or trenches, the depth of holes and grooves is 4 cm and 5 cm. When the soil is dry, it is wet with water first. The seed bud eyes are facing up, and the cover soil is 3-4 cm thick.

Third, field management. The seed block is sown and covered with grass. During drought, water is used to water through the mulch, or irrigation ditches to make the ground moist. After the seedlings come out, remove the mulch in batches. Weeding and weeding with loose soil at the seedling stage, and drenching with dilute dung water for 2 times, and then strengthen the management of fertilizer, water and soil cultivation as appropriate. It can be harvested in about 3 months.
