Cultivation of amaranth is still dominated by seed reproduction, and high-quality varieties can be selected. Soak seeds with about 55 degrees of hot water before planting. Soak it in warm water for 12 hours, and germination for 2 days to 3 days at a temperature of about 25 degrees. Spring sowing is before and after the Qing dynasty to Qingming, and the autumn is broadcast before and after the cold dew. The seedbed should be selected from loamy or well-drained loam or sandy loam soil, and the base fertilizer should be used to make sorghum. After planting to survive, look at the soil moisture and growth, carry out cultivating and weeding, timely irrigation, topdressing and rare manure or urea and water pouring. In order to make the new planting leek grow vigorously, it can be harvested when the leek is about 25 cm in the next year. In the application of fertilizers, the pollution-free leeks should be applied more with farmyard manure, and the unfertilized human excrement and nitrate nitrogen fertilizer should be banned. Note that it is forbidden to use 10 days to 15 days before harvesting.
If the leek is continuous, it will cause serious pests and diseases and poor plant growth. The main problems are: the disease is dark green water-immersed lesions, and the medicine can be rooted or sprayed with 600 times of "creaming copper wettable powder" or 600 times of "ethylphosphorus aluminum" 600 times. Rust can be controlled by 15% "triazole copper" 2000 times liquid or 25% "powder rust" 1000 times liquid, 50% "quickling" 1500 times liquid. The mites can be treated with 40% "Lego" emulsifiable concentrate 1000 times solution and 50% "anti-èšœå¨" 1500 times solution. Amaranth can be sprayed or rooted with pyrethroid pesticides, and can also be rooted with 40% "phoxim".
