1、 Soil

Millet does not have strict requirements for soil, but it is most suitable to grow in neutral soil with loose soil, thick black soil layer, good drainage and rich organic matter. Due to the poor salt tolerance of millet, if it is planted in saline alkali land, the planting amount should be appropriately increased

2、 Illumination

It is a crop that likes light and short sunshine. Insufficient light will lead to thin and high seedlings, less chlorophyll content and dry matter accumulation. Especially in the later stage of its growth, it needs sufficient light, because 92% of the dry matter accumulation of seeds comes from photosynthesis in the later stage

3、 Temperature

It likes temperature and has different requirements for temperature in different growth and development stages. In the growth and development stage, the average temperature should be 20 ℃, and in the germination stage, the minimum temperature is 7-8 ℃, and the optimum temperature is 24-25 ℃. When the temperature is lower than 7 ℃, proper insulation is required to avoid freezing injury

4、 Watering

Millet is a drought tolerant crop and generally does not need watering. However, in the jointing booting and grain filling period, in case of drought, it should be watered in time and followed up with booting fertilizer, which can promote the growth of ears, compete for the number of grains, and increase the seed setting rate and 1000 grain weight

5、 Fertilization

It likes fertilization, and generally fertilization is divided into three stages. The first stage is base fertilizer, which is mainly farmyard fertilizer, mixed with calcium superphosphate as base fertilizer, and applied into the soil when turning over the land or ridging. The second is planting fertilizer, which generally uses diammonium phosphate and a small amount of nitrogen fertilizer to promote the early growth and rapid development of grain seedlings. The third is topdressing. When the seedling height is 30-50 cm, apply nitrogen fertilizer
