Sweet sorghum varieties should be selected for planting forage sorghum. Sweet sorghum stems have high sugar content, strong resistance to leaf diseases, tall plants and high yield. Sorghum should avoid continuous cropping. Continuous cropping will greatly affect the yield, because it consumes more soil fertility, reduces fertility and easily causes diseases such as smut. Sorghum is not strict with previous crops, and beans and leafy vegetables are better. Before sowing, apply sufficient organic fertilizer, dig deep and rake carefully, and level the ground; When sowing, apply a proper amount of seed fertilizer. Sowing can be done in row or on demand, with the row spacing of 60 cm, the sowing depth of 3 ~ 5 cm and the sowing amount of about 1.5 kg per 666.7㎡. After the emergence of sorghum, intertillage and weeding should be carried out, and irrigation and fertilization should be carried out 1 ~ 2 times if possible to prevent and control pests and diseases in time. Sorghum harvested seeds should be harvested after the shell turns yellow. For silage, the stubble is 7 ~ 10 cm when the seed is mature, and it is mowed when the plant height is above 1.5 m when it is used as green feed. Irrigation and fertilization after cutting sorghum can promote the regeneration of stubble without replay. Generally, the seed yield of sorghum is 200 ~ 300 kg /666.7 m2, and the stem and leaf yield is 4000 ~ 6000 kg /666.7 m2.
