Summer season is the golden season for grass sowing. However, the germination rate of the live grasses is often low, which not only causes the waste of seeds, but also affects the amount of grass production per unit. If the pre-planting treatment can be properly performed according to the different characteristics of different pastures, not only will it greatly increase the germination rate, but it will also contribute to the growth of forage grass, which will increase the amount of grass production per unit area by more than 30%.
1. Hard treatment Because the seed coat of Leguminosae grasses such as alfalfa, rhinoceros, etc. has a tight array of Martens cells, it is difficult for water to infiltrate directly after sowing, which directly affects germination. Before planting leguminous herbage, it should be hard-treated. Methods are as follows: 1. Rub the seed coat. Roller can be used roller or roller mill treatment, can also be mixed with a certain amount of gravel, gravel, legume, gravel, gravel, stirring, stirring stirring, until the surface of the seed rough hair, the strength of the seed is not crush should. 2 Variable temperature soaking. It is generally used where the soil is moist or well-watered. Usually the seeds are soaked in water for 1 day and night and then removed. They are exposed to the sun during the day and cool at night. Water is often added to keep the seeds moist when most of the seeds are inflated. When you can, you can sow according to the public opinion. 3 add acid treatment. Add 3% to 5% of dilute sulfuric acid or hydrochloric acid to the seeds, stir evenly, and then when the seed coat appears cracks, clean the seeds with water, and add seeds for drying.
2. Inoculation treatment legume grass can symbiotic nitrogen fixation with rhizobia, but the formation of legume nodules is closely related to the number of rhizobia in the soil, especially for the first time in Xinyi land planted legumes, or replanted on the same plot The same type of legume herbage, or legumes grown on excessively arid and high-acid lands, must be inoculated with rhizobial bacteria to increase the amount of soil in order to increase the yield and quality of leguminous herbage. At present, there are mainly three kinds of inoculation methods: 1 dry tumor method. The roots of the leguminous pastures at the flowering stage were selected, washed with water, and allowed to dry slowly in places sheltered from the wind, cool, and inaccessible to the sun. The pasture was ground and dressed before sowing. 2 fresh tumor method. The rhizobia 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 days to 5 days. The fungus is then mixed with the fungicide. Species. 3 Rhizobium dressing method. The rhizobia agent was sprayed onto the seeds according to the instructions. The standard proportion of commonly used seed dressings was 1 kg seed with 5 g of the bacterial agent. When inoculating rhizobial bacteria, it is necessary not to use seed dressing together with pesticides, and not to inoculate directly under direct sunlight. Seeds that have been seeded with rhizobia are not exposed to quicklime or large amounts of fertilizer, so as not to kill Rhizobium. This method should pay attention to the mutual inoculation of Rhizobium with the same family and different groups of vaccination is invalid.
3. Soaking seedlings for seedlings such as Polygonaceae and Compositae must be soaked before sowing by soaking the seeds in warm water for a period of time. The water temperature and soaking time can be determined according to the characteristics of the seeds. For example, seedlings of pine cones are soaked in water at 30°C for 12 hours before sowing, and then sowed; Rumex K-1 is soaked in cloth and put in 40E water for 6 hours to 8 hours before sowing. After drying and drying, the germination is carried out in the environment of 25°C to 28°C for about 15 hours. About 70% to 80% of the seeds are sown and then sown. 4. Many mango grasses often have burrs, glumes, and other appendages. These appendages are not easily removed during harvesting and processing. To increase the germination rate of the seeds, a man-made machine or a circular repressor after pressure screening method should be used to carry out mango processing.
