A spraying system for improving the fixing rate of leguminous forage and a method of using the same
By using a spraying system to apply inhibitors and sow leguminous forage seeds in high-coverage natural grasslands, the problem of weak seedling competitiveness was solved, the seed setting rate and survival rate of leguminous forage were improved, and the grassland's forage supply capacity and the sustainable development of animal husbandry were enhanced.

AI Technical Summary
The weak seedling competitiveness and low establishment rate of leguminous forage in high-coverage natural grasslands have limited the large-scale promotion and application of reseeding technology in high-coverage natural grasslands. This has resulted in a low proportion of leguminous forage in natural grasslands, low crude protein content, and poor quality, which restricts the supply capacity of natural grasslands to high-quality forage.
The spraying system applies inhibitors to both sides of the no-till reseeding rows. By combining the seeding mechanism, spraying mechanism, and restriction mechanism, the competitive inhibition of native vegetation is reduced, providing a window of time and space for the growth of reseeded leguminous forage seedlings. This includes the design of the seeder, spraying mechanism, and restriction mechanism, spraying inhibitors and sowing forage seeds, using the tillage assembly to pre-plow the seeding rows, and the pressing wheel to ensure close contact between the seeds and the soil.
It significantly improved the establishment rate of reseeded leguminous forage grasses, avoided competition between native vegetation and reseeded seedlings for nutrients, water and light resources, improved the survival rate and growth rate of leguminous forage grasses, and enhanced the sustainable development capacity of grasslands.
