Many leguminous seed coats have a layer of closely packed long columnar Martensitic cells that are not easily penetrated by water and impede water swelling and sprouting. The hardiness rate of alfalfa is 10%, and that of rhinoceros is 39%. Therefore, hard seed must be treated before planting leguminous pasture.
Hard treatment 1. The seed coat can be crushed with roller mills or treated with a roller compactor. Legume grass seeds can also be mixed with a certain amount of crushed stone and gravel and put into a stirring shaker to stir and oscillate until the seed surface. Rough fluff, but it is better not to crush the seeds.
2. Variable temperature seed soaking can be used in places where the soil is moist or well-watered. Usually the seeds are soaked in hot water and soaked overnight. Exposure to the sun during the day, cool to night, and often add some water to keep the seeds moist. When most of the seeds are inflated, they can be sown according to the lyrics.
3, acid treatment Add sulfuric acid or hydrochloric acid to the seeds and stir it evenly with the seeds. When the seed coat cracks, put the seeds into running water to clean, and add a little drying to sowing.
The inoculation of leguminous forage legumes together with rhizobium solidifies ammonia, but the formation of legume nodules is closely related to the number of rhizobia in the soil, especially for leguminous forages for the first time on Xinyi land, or on the same plot. Planting the same leguminous herbage again or planting leguminous herbage on excessively arid and high-acidity plots requires inoculation of rhizobial bacteria to increase the number of root nodules and improve the yield and quality of legume herbage.
When leguminous grasses are inoculated with rhizobia, the type of rhizobia must first be determined based on the species of herbage, and the scientific inoculation method must be followed. Inoculation method is currently used in the actual combat more than three kinds: dry tumor method, bright tumor method and bacterial seed dressing method.
1. The dry nodule method is to select the root of leguminous herbage at the flowering stage, rinse it with water, place it in a place sheltered from wind, darkness, coolness and sunlight, and make it dry slowly. Grind dressing and dressing before forage sowing.
2. The method of bright tumor is to immerse the rhizobial bacteria or ground roots in a small amount of water and mix them with cooked soil and mix them at 20Â°C-25Â°C for 3-5 days. Seed dressing.
3, rhizobium agent seed dressing is the rhizobial product manufactured in accordance with the instructions bactericidal liquid sprayed on the seed, the standard proportion of seed dressing rhizobium is 1 kg of seeds mixed with 5 grams of bacteria. When inoculating rhizobial bacteria, it is necessary not to mix seeds with pesticides and inoculate directly under direct sunlight. Seeds that have been seeded with rhizobium do not come into contact with quicklime or a large amount of fertilizer to avoid killing and killing rhizobia and inoculating the same family with rhizobia. Mutual vaccination is invalid.
In addition, some of the seeds of grasses often have appendages such as awns and glume. These appendages are not easily removed during harvesting and processing. In order to ensure the seed quality of the seeds and the smooth progress of the drying and cleaning, the seeds should be treated with awns. Going to the mansard can be done using a mansard machine or after pressing with a ring-shaped suppressor.
For the germination of other forage grasses, both the Polygonaceae and the Compositae herbage are generally soaked with germination before sowing. The method is to soak the seed in warm water for a period of time. The temperature of the water and the length of the soaking time can be determined according to the characteristics of the seed. For example, seedlings of pine cones are soaked in water at 30Â°C for 12 hours before sowing, and then sowed; Rumex will sow seeds in cloth soaked in water at 40Â°C for 6-8 hours before sowing. After drying, the seeds were germinated at 25Â°C-28Â°C for 15-20 hours. When the seed embryos were about 70Â°C-80Â°C, they were sown. Under good conditions, it can be broadcast live.
