First, the root preparation: You can use the old amaranth roots that have been eliminated or discarded. You can also cultivate the annual new amaranth root. The former produces yellow leaves with wide width, but the yield is low. The latter leaves are narrower, but the yield is high.
Second, excavation pool: choose the leeward sun, digging things to the pool, the pool is 14 to 17 meters long, the pool is 2.7 meters wide, the pool depth is 0.8 to 1 meter. In the pool, it is divided into 2.7 by 1.7 meters and 8 to 10 small pools. In the northern half of the big pool, half of the roof is set up with wooden frames, covered with corn stover or two layers of straw felt. Set up a wind barrier on the north side of the ground.
3. Roots into the pool: Squeeze the roots that have been stored and stored in the pond, plant them in the pool, level them and then water them. After 4 to 5 days, lay a layer of 3.3 to 5 cm thick horse manure on the roots of the roots. Cover with 3.3 cm thick bristles for germination. After 2 to 3 days, the horse manure began to heat up, and the temperature rose to 20 to 30 degrees in 6 to 7 days. When the amaranth grows to about 3.3 cm, the horse dung is immediately taken out to lower the temperature. The yellowing grows slowly; if the temperature is too high, it is prone to burn out the amaranth. If the temperature exceeds 40 degrees, all the amaranth may be burned out.
Fourth, post-fertilization management: generally 4 to 5 days after the dung, water is poured. Temperature management pays attention to the first high and then low; temperature adjustment is carried out by uncovering the grass felt, and uncovering the grass felt, it should be determined by the weather conditions and the growth of the leek. The weather is good, and the leek grows faster and strengthens the air. Cover the plastic film when drying. Pay attention to the drying time from the short time to the lengthening, in order to refine the seedlings.
