What is the sowing mechanization technique of pasture?
1) Seeding methods: (1) Arable land with high land flatness, good surface and large area should be sown by machinery. (2) Mechanical drills are suitable for the treatment of various land parcels to be treated according to the arable land requirements. Draw spacing can be controlled between 15 to 30 cm. (3) Artificially spreading small plots or intercropping methods. 2) Sowing volume: The control sowing volume should be controlled according to the needs of different pasture varieties. The adjustment of the amount of sowing is to adjust the sowing rate by changing the rotation speed of the driving wheel and the seed wheel according to a specific operation instruction by changing the seed wheel and the seeder with a speed regulation seeding amount. For seeders with a fixed transmission ratio, the sowing rate is adjusted by changing the effective length of the row of grooved wheels. 3) Depth of sowing: The sowing depth should be controlled according to the needs of pastures of different species. The adjustment of sowing depth of the implements is carried out according to the operating instructions of the specific model of the sowing machine. 4) Post-planting treatment: (1) After sowing with no repression device, the following treatment measures should be taken according to the soil moisture conditions: Debris - suitable for spring sowing, and the soil moisture is poor. Repression - suitable for arable land. Defective land - suitable for sowing in summer, soil moisture content of 15 to 20%, according to the changes in the surface surface of the soil and seed germination situation to take the next step to suppress the follow-up measures. (2) Work Tools: The cookware is a short-tooth-type nail file. The weight of the cooking utensils is about 5 kg, which can be replaced by round logs and iron pipes that are slightly longer than the seeder. The cooking utensils can be planted after the planter and the seeding can be completed in one operation.
