Teaching of management skills in amaranth cultivation

1. For soil preparation and fertilization, we should select the land with flat terrain, convenient drainage and irrigation and few weeds, turn the soil deeply (and spray disinfectant and 800 times liquid of new high-fat film to disinfect the soil), combine with deep turning and apply sufficient base fertilizer to make flat beds. it is required that the ground is flat and the soil is fine to facilitate seedling emergence.

2. Sowing and raising seedlings should be sowed at the right time, and the seeds can be sowed directly on the seedling field (new high-fat film is applied to seed dressing before sowing), then a layer of plant ash is sprinkled, and topdressing is timely watering according to the weather and soil, and 800-fold liquid of new high-fat film is sprayed on the surface to protect soil moisture, prevent soil slabs and improve seed germination rate.

3. Field management, weeding should be done in time after emergence, water and fertilizer management should be strengthened to keep the soil moist. Topdressing should be sprayed with thin liquid fertilizer dominated by nitrogen fertilizer, and sprayed with 800-fold liquid of new high-fat film to improve fertilizer efficiency. In the growth stage, Zhuangtuanling should be sprayed to make the plant stalk stout, leaves fat, amaranth disease resistance, reduce the amount of pesticide and chemical fertilizer, reduce residual poison, and improve the natural taste of spinach.

4. to control diseases and insect pests, amaranth has strong disease resistance, and the main disease is white rust. Dysenmeng zinc can be used to control and spray 800-fold solution of new high-fat film to improve the utilization rate of effective components, and the main insect pests are aphids. Imidacloprid plus 800-fold solution of new high-fat film can be sprayed.
