Last Updated: 2024/11/08, When to sow sorghum the planting of sorghum can be divided into spring planting and autumn planting. Spring sowing time is about the end of March to mid-April of the lunar calendar, the time should not be too early, because the early sowing temperature is low and the growth is slow, it is easy to die in the cold, while autumn planting is chosen under the fifth month of the lunar calendar.

When will sorghum be sown?

The planting of sorghum can be divided into spring cropping and autumn cropping. The sowing time of spring planting is about the end of March to mid-April of the lunar calendar, and the time should not be too early. Because of the low temperature and slow growth in the early stage, it is easy to wither and die in the cold spell, while autumn planting is chosen to sow between late May and late June of the lunar calendar, and the time should not be too late, so as not to encounter low temperature in the middle and later stages of growth, affecting the growth and delaying the mature period.

Planting density of sorghum

The plant density varies in different regions, but the range is 90 ~ 120000 plants per hectare (grain sorghum) or 70 000 ~ 90 000 plants per hectare (sweet sorghum). The general principle is that early-maturing varieties should be denser and late-maturing varieties should be sparse; varieties with strong lodging resistance should be densely planted and varieties with poor lodging resistance should be sparsely planted; the density of high-fertility plots is higher and that of low-fertility plots is lower. But the general principle is reasonable close planting, which is an important prerequisite for high yield.

Planting environment of sorghum

Because sorghum is drought-resistant, waterlogging-resistant, saline-alkali-resistant and barren, sorghum can be planted in low-lying, barren and dry saline-alkali land. As long as the corresponding cultivation techniques and measures are taken in farming, a better yield can still be obtained. Reasonable crop rotation has a great effect on yield. Soybean stubble is the most ideal previous crop for sorghum planting, followed by wheat and corn stubble. Because the root system of sorghum is deep in the soil, has a wide range of expansion, and absorbs a lot of water and nutrients, resulting in the decline of soil fertility, the best follow-up crop is soybean stubble.
