1) Soil preparation and sowing:

Leveling the border surface, opening a border ditch with a depth of 23cm 1 cm on the border surface, evenly mixing the seeds with the fine sand by 5- 10 times, evenly spreading the seeds in the border ditch, and lightly covering the seeds with subsoil, wherein the seed consumption per mu can reach 500-700g. ..

2) Post-broadcast management

When the temperature is high and the moisture is suitable, the seedlings can emerge 2 ~ 4 days after sowing, and the amaranth grows slowly at the seedling stage. Pay attention to weeding. After sowing, after 10 days, when the seedlings grow to 3 ~ 4 cm high, the spacing between seedlings should be 5 cm. Sow in furrow, 20 days after emergence, when seedling height 15cm, seedling height 15cm, seedling spacing 10cm. Topdressing after thinning 1 double fertilizer, topdressing per mu 15kg ammonium nitrate, water application. During the growth period, topdressing 1 time after each harvest, watering with 300 times urea water, about 5 kg per mu, and watering for 2 ~ 3 times. Pay attention to weeding during growth.

2. Purslane weeding:

Herbs such as Gramineae and Gaicaoneng can be used for weeding, which has special effects on Gramineae weeds and has no effect on broadleaf seedlings.
