The best sowing date of sorghum

Sorghum should be planted in Guo Qian County, Songyuan City from May 15 to June 5, depending on the spring temperature. The temperature is 5- 10 cm below the ground, and only after 10- 12 degrees, can the local corn be planted, that is, before and after emergence. Because sorghum seeds are easy to pollinate, resulting in uneven emergence, it is necessary to master the ground temperature and not sow it too late. At present, the maturity of high-yield sorghum seeds is long, so it is necessary to sow them early in time while ensuring the emergence of seedlings.
