Seeds larger than seeds are usually seeded more than grain seeds; more sowing grassland is harvested than harvested grassland; sowing seed is more than drill seeding, drill seeding is more than seed sowing; low temperature in early spring or sowing in arid area, sowing rate should be higher than early spring Temperatures rise quickly or in wet areas; seed quality should be poor and soil conditions should be poor. Seeding methods include seeding, sowing, sowing with fertilizer and sowing of furrows. Drilling refers to sowing the seeds into rows at regular intervals and sowing the soil with the sowing method. In wet areas or areas with irrigation conditions, the line spacing is generally about 15 cm; in dry conditions, a 30 cm line spacing is usually used. The range of grass used for harvesting is generally 45-100 cm. Spreading seeds is to spread the seeds evenly on the surface of the soil and then gently cover the soil. In cold regions, the seeds can be sprinkled on the ground in the winter without covering the soil. The seeds are buried in the soil by the natural action of freezing and thawing. Fertilizer sowing is when sowing, the fertilizer is applied under the seed, the depth of fertilization is generally 4-6 cm below the sowing depth, mainly applied phosphate fertilizer. Furrow sowing can be used in arid and semi-arid areas where there is thicker surface soil. The method is to use machinery, animal power or manpower to open the ditch and spread the seeds on the wet soil layer of the furrows. The furrows will not be flattened and will be flattened by the pasture harvest or the end of the growing season. High-cold areas can also be sown by this method to increase the overwintering rate of pasture.

Early arrangement of pasture
The sowing time can be divided into spring sowing, summer sowing and autumn sowing. The specific time for sowing depends on factors such as temperature, moisture, the biological characteristics of the pasture, the degree of damage to the weeds in the field, and the purpose of use. When the soil temperature rises to the minimum temperature required for seed germination, it is appropriate to sow when the moisture is good, the weeds are few, and the pest and disease damage is light. In arid regions, the soil moisture content is mainly considered, while in cold regions, the overwintering nature of forage grasses is considered.
