First, hard treatment Before sowing legumes, hard seeds should be dealt with. Treatment methods are: First, scratch the seed coat. Roller mills can be used for roller compaction or roller compactors. Legume grass seeds can also be mixed with a certain amount of crushed stone and gravel and placed in a stirrer to oscillate until the surface of the seed is rough and rough, but the seeds are not crushed. should. The second is variable temperature soaking. This method is applicable to places where the soil is moist or well-irrigated. Usually the seeds are soaked in hot water for 24 hours and then removed. They are exposed to the sun during the day, cool to the night, and often add some water to keep the seeds moist. When most of the seeds expand slightly, they can be sowed. . The third is to use acid treatment. Add 3%-5% dilute sulfuric acid or dilute hydrochloric acid to the seed and stir it evenly. When the seed coat cracks, rinse the seed in flowing water and dry it with a little drying.
2. Inoculation treatment Legume forages were planted for the first time in Xinyi land, and the same legumes were planted again on the same plot, or Legumes were planted on overly arid and high-acid plots, all of which were inoculated with root nodules. The commonly used inoculation methods to increase the number of nodules by bacteria are: (1) Dry tumor method. The root of the leguminous pasture was selected during the flowering period, washed with water, and slowly dried in a sheltered, dark, cool place. The seeds were ground and dressed before sowing. (b) Fresh tumor method. The rhizobial bacteria or ground roots are diluted with a small amount of water, mixed with cooked soil, and incubated at 20°C to 25°C for 3 to 5 days. The fungicide is mixed with the seeds to be sowed. (3) Rhizobium dressings. The rhizobia agent was sprayed on the seed according to the instructions. The seed was mixed with 5 g rhizobium agent per kilogram of seed. When rhizobia are inoculated, they must not be mixed with pesticides, and they must not be seeded in direct sunlight. The seeds that have been mixed with Rhizobium do not come into contact with quicklime or a large amount of fertilizer. Inoculation with rhizobia is effective, while inoculation of different families is ineffective.
Third, to Mansard treatment For some grasses forage seeds to go mansing treatment. Going to the mansard can be done with a mansard or with a ring roller for cutting and screening.
4. Soaking seed Seeds of Lycium and Compositae herbage are soaked in warm water for a period of time before sowing. Seeds of pine cone herb are soaked in water at 30°C for 12 hours before sowing, and then sowed; Rumex is Before sowing, the seeds should be soaked in water at 40°C for 6-8 hours, then left to dry and germinated at 25°C-28°C for 15-20 hours. 70%-80% of the seeds are shelled. When you sow. Of course, under conditions of better lyrical conditions, all kinds of pasture seeds can also be broadcast live, but the soil should be kept moist.
