1. Site preparation. The saline-alkali viscous soil is suitable for autumn irrigation and winter irrigation. The top of the soil is shaved so that it can be well-disturbed before sowing. Seeds should be full, uniform, uniform, strong germination potential, and strong ability to excavate soil. Spring sowing should avoid low temperatures, not earlier than in early May. The amount of mu will be required according to varieties, such as low bud rate, low germination potential, or insufficient lyricism. Or the quality of the site preparation is not good, the amount of sowing should be increased. When sowing, due to the small amount of sowing, the seeds are small, the sowing feet are easy to be blocked, and the hopper box should not be placed too much seeds in order to judge whether or not missed sowing by observing the change of the seed stock. Depth 3-4 cm, timely suppression after sowing. 2. Chemical weeding. The sorghum is sensitive to herbicides and should be used with safety in order to avoid phytotoxicity. Chemical weeding should be based on pre-planting soil treatment. Use Metolachlor (Dore) or Metolachlor (Dore) plus Atrazine to uniformly spray water on the soil surface. Do not leak. Avoid post-emergence stems and leaves as much as possible Treatments, such as serious seedling damage due to grass, in the 3-5-leaf sorghum period, atrazin spray uniform weed stems and leaves, control of annual and biennial broadleaf weeds and monocotyledonous weeds. 3. Control pests. The main pests that harm sorghum are aphids and panicle aphid pests. The latter poses a great danger to the tight panicle type and has a strong concealment. It is a deadly pest of sorghum. Sorghum is very sensitive to various drugs such as trichlorfon, lime sulphur, and safrole, and it is necessary to pay more attention when spraying so as not to cause phytotoxicity. It is better not to control locusts Yichi, the early eradication of the central pupa strain, the use of high-efficiency cypermethrin, imidacloprid control effect is better. Prevention and control of ear aphid pests in the egg hatching or larvae before the 2nd instar, is also before the sorghum flowering and early filling stage, with a peacekeeping salt or Bai tree, deltamethrin, cypermethrin and other pyrethroid insecticide spray ear Good control effect. 4. timely harvest. The best harvesting time is generally at the end of wax ripening stage and early maturing stage. At this time, most of the grains of the whole panicle have been fixed and hardened, and show the inherent color of the variety. The grains at the base of the ear solidify into a waxy shape, and there is no white pulp.
