Ryegrass is an annual tetraploid grass that has a cool, moist climate and is one of the best quality pastures in any cultivated pasture. In southern China, the main use of winter farmland, ditch side, pond base and other fertilizer and water conditions are better planting, sowing in late autumn, winter and spring mowing. It has the characteristics of rapid growth, high yield, high nutritional value, good palatability, long supply time, fertility, and promotion of post-cultivation. Its cultivation and management and use are as follows: 1. Seed rye grass seed germination temperature suitable for 13 °C -20 °C, less than 5 °C or higher than 35 °C germination is difficult. If you use winter farmland, you can sow before and after late rice harvest. The suitable sowing period in our province is from September to October. 2. Seeding method (1) Tillage sowing: Plough the soil first, and then press the width 1.5-2.0 meters, the groove width 0.3 meters, after the leveling, the sowing amount according to 1.5 kg / acre sowing or spacing by 20- 30 cm drill. After the seeds are sprinkled, the soil is reconstructed and repressed with nails so that the seeds are tightly integrated with the soil. The advantages of this sowing method are loose seedbeds, convenient drainage and irrigation, and high yield of fresh grass. (2) Paddy field planting: The ryegrass seeds are soaked in cold water for about 5 to 8 hours before the harvest of late rice, picked up and drained, and mixed with fine sand to sow. Seeding capacity 1.5 kg/mu. Cut as low as possible during harvest to avoid rice blasts affecting the harvest of ryegrass in the future. The advantage of this sowing method is that it can avoid ploughing, sowing in advance, extending the growth period, and saving labor. 3. Field management The field management of ryegrass should closely focus on the two links of water and fertilizer. Ryegrass is so wet and afraid of flooding, so it is necessary to open the ditch immediately after sowing, so that the ditch can be matched to facilitate timely drainage and waterlogging to prevent waterlogging. In addition, ryegrass is sensitive to nitrogen fertilizers, and fertilization combined with irrigation can greatly increase the yield and quality of ryegrass. Therefore, ryegrass must be applied to the base fertilizer before sowing, and can use 40-50 kg of compound fertilizer per mu. After emergence, fertilizer should be applied once in the three-leaf stage and the tillering stage, with 5-10 kg of urea per acre. Each time after cutting, it is necessary to top-dress one time. Mushi urea or compound fertilizer is 10-15 kilograms. In order to prevent cut rot, fertilization should be repeated 3-5 days after mowing. Rice ryegrass can be topdressed with compound fertilizer 40-50 kg per mu after cutting rice. 4. Harvesting and utilization When the ryegrass grows to a height of 40-50 cm, it can begin to cut the first time. After that, it is harvested once every 20-30 days. Each time the mowing is done, pay attention to the remaining 5-6 cm to regenerate. Cut grass can be directly fed cattle, sheep, pigs, ducks, geese, chickens and other livestock and fish. Unused fresh grass can be stored in silage for use. About 10 days before rice transplanting, the ryegrass was turned over and put in water to promote the rot of the ryegrass and promote the growth of rice. China Agricultural Network Editor
