Tall ryegrass is a medium-early-maturing tetraploid cultivar with a warm, cool and humid climate. It is cold-tolerant, moisture-resistant and salt-tolerant. However, it is resistant to high temperature and drought, and the optimum growth temperature is 10-28°C. It can be planted in various areas of our province. Many years of research and promotion have proved that: Our province uses the winter free field to plant multi-flowered ryegrass, which can produce high-yield and high-quality green fodder without affecting grain production, effectively alleviating winter The supply of high-quality green fodder is in short supply in the spring, and the development of livestock husbandry and aquaculture is promoted, and farmers' income is increased. Tallgrass ryegrass is the best ryegrass variety in our province to establish the "early rice-late rice-multi-flower ryegrass" grassland rotation farming system.

Compared with other ryegrass varieties, the benefits of planting ryegrass grasses are: First, fast growth, high yield. The first time the grass is cut after 45 days of sowing, and once every 20-30 days, the yield of fresh grass is as high as more than 5 months (up to 6 months in northern Fujian). 7000-10000 kg. The second is good palatability, high nutritional value, and significant feeding effect. The grasses of Tallgrass and ryegrass are soft and juicy, and their palatability is particularly good. All kinds of livestock, poultry, and herbivorous fishes are eager to eat. The feed intake rate is 100%, and the nutrition is abundant. After feeding geese with ryegrass for 70 days, the average weight of each goose was 0.1 kg more than the control group fed with vegetative leaves, and 4.1 kg of concentrated feed was saved. The day of growing pigs from 25-90 kg of “internal binary” was increased. Add 25% and 30% of Tall Dorsal Ryegrass to grain, increase daily weight from 584g of control to 610g and 600g respectively, and save 10% and 20% of concentrated feed respectively, and slaughter rate, lean meat percentage and meat quality There are no significant differences. It can also increase the milk production of dairy cows. The yellow level of eggs and eggs is about 5 grades higher than that of the control group. The third is to improve soil fertility. Post-production rice production increased significantly.

Cultivation techniques

1. The selection of highland ryegrass is not strict with the soil, but in order to obtain high yields and high quality, the land with loose texture and fertility and certain drainage and irrigation conditions should be selected, such as winter farmland, orchards, banks of fish ponds, beside ditch or mixed lands. Etc.

2. The optimum germination temperature of the seeds of multi-flowering ryegrass at the seeding stage is 13-20 °C, and it is difficult to germinate when the seeding period is lower than 5 °C or higher than 35 °C. Below 5°C, the growth of the aerial part basically stops. Therefore, the sowing period from south to north of our province can be followed by frost (from late October) to white dew (mid-September). It is advisable to stabilize the temperature below 30°C or above 13°C.

3. Seeding method

(1) No-tillage method This method can save a lot of labor, but the output is low. After low-yielding rice is harvested, drainage and irrigation trenches are to be excavated around the rice fields and in the middle. The seeds are soaked in cold water for 1-2 hours and then sown uniformly on wet rice fields. The amount per mu is 1.5-2.0 kg. And keep it moist for a week or so, the seeds can be seedling growth, or soaked seeds can be evenly sowed in wet rice fields 20 days before the rice is harvested. The rice should be harvested as low as possible to avoid rice blasting. The management and harvest of ryegrass in the future. In comparison, the latter is more suitable for the application of dry and dry areas.

(2) After plowing and sowing method, the land ploughs are leveled, and the width is 2 meters from the rake. The spacing is 25-30 cm, and the depth of cover soil is 1 cm after sowing. The seeding rate is 1.5 kg/day.

(3) Tillage sowing method After the land ploughs are leveled, press the width of 2 meters to start the shallow pod sowing. The distance between holes is 25-30 cm, 5-6 seeds per hole, 1 cm deep after sowing, and the seeding rate is 1 kg/mu.

4. Field management

Tall flower ryegrass hi wet and afraid of flooding, water stains, the growth process should be timely irrigation and drainage, to quit, not stain for degree; very sensitive to nitrogen fertilizer, combined with irrigation when applied nitrogen fertilizer, can greatly increase its yield and quality . Generally, 2000-3000 kg of organic fertilizer or 10 kg of compound fertilizer is used as base fertilizer per acre before sowing. Every 2-3 days after mowing, Mushi compound fertilizer 10-15 kg, be careful not to burn grass head, causing rot. Every time after top dressing, it should be irrigated to facilitate absorption of nutrients and to avoid fertilizer damage.

5. Harvesting and utilization

45-50 days after sowing, the height of the grass layer is about 40 centimeters, and the first time the grass can be cut. After that, depending on the growth and utilization, the grass is cut every 20-30 days. If it is used to feed large animals such as cattle and sheep, the interval between mowing the grass may be appropriately extended and the grass layer may be castrated at a height of 80-100 cm. Cut grass can be directly used to feed livestock and herbivorous fish. If it is used to raise pigs and raise poultry (goose), it can be shortened appropriately to increase the feed intake and reduce waste. Lolium multiflorum has a higher moisture content, and after harvesting, it must be sown and dried for a day before the grass wilts and then feed the livestock and poultry to avoid “rare leaching”.

6. Winter Management

When the temperature is lower than 5°C, the growth of the ground part basically stops and it enters into hibernation over winter. The mowing should be stopped 15 days before entering winter to facilitate wintering. After winter, when the average temperature reached 8°C on the same day, it began to turn green. At this time, field management, fertilization, irrigation, and growth of ryegrass should be strengthened to increase yield and quality.

7. Last mowing time

In order not to affect the post-crop rice production, it is recommended that the last harvest be carried out 15 days before rice transplanting, and plowing fields should be filled with water so that the rye grass roots and roots can be decomposed and converted into organic matter, which will facilitate the growth of the crops. In order to promote the rot decomposition of ryegrass and improve the acidic soil, 15-20 kg of lime per acre can be combined in the plow field, which can play a very good effect.
