I. Botanical properties of Ryegrass Ryegrass is a clustered annual grass crop. The roots are well-developed, with many branches and dense; the stems are 50-120cm in height, and the stems are erect, round, soft; the ability to deliver is strong, averaging about 60.
Second, the biological characteristics of Ryegrass Ryegrass is a warm and wet grass, cold resistance is not strong, can not resist the night cream, but its seedlings can tolerate the low temperature of 1.7-3.2 °C, the plant at day and night temperature 25 The fastest growth rate is at /12°C. Drought resistance is also very poor, and it is most suitable for growth where the precipitation is 1000-1500mm. Like fertile and deep loam or sandy loam, generally sticky soil can also grow, not long-term water.
Third, the economic value of special high ryegrass high ryegrass main characteristics are fast growth, strong tiller, regenerative, a growth season can be cut many times, usually 3-5 times a year, 5000 acres per mu - 6000 kg of fresh grass, when sufficient fertilizer is applied, it can reach 8000-9000 kg of fresh grass.
Ryegrass is razed during vegetative growth, and the crude protein content in dry matter is more than 20%, and it is rich in various minerals and trace elements. After livestock and poultry feed, daily gains have increased significantly. According to the information provided by the Ministry of Agriculture, after testing in Yunnan Province, 36.7 kg of ryegrass plus 1.7 kg of feed can increase 1 kg of live cattle, and 8 kg of fresh grass can increase 1 kg of fresh milk.
Fourth, the cultivation method
1. Sowing time: After many years of practice, the suitable sowing date for high-lying ryegrass at low altitude in Yunnan is from late August to late September, that is, tillage is sown after rice is harvested. But do not exceed October at the latest.
2, sowing method: There are two kinds of sowing method of high ryegrass, that is, no tillage sowing and tilling sowing, the yield ratio of these two sowing methods is about 0.9:1.1.
1. No-tillage sowing: This is the most extensive production method, which can save labor, but the output is low, generally not advocating.
2. Tillage sowing: There are three forms of ploughing and sowing, namely, drilling, sowing and sowing. After many experiments in Yunnan province, the best sowing is achieved. The method is to plough the field ploughs finely, and then press a width of about 2 meters to form a row with a spacing of 20-30 centimeters and a broadcast amplitude of 5 centimeters, 0.8-per-mu. One kilogram sowing amount, soaking with fine sand or calcium magnesium phosphate fertilizer, sowing soil 1 cm after sowing and irrigating water, in order to promote seed germination and conducive to seedling growth. Sporadic fields can be excavated, broken and flattened and then used for pond sowing. The distance between the ponds is 1515 cm. Per acre sowing rate of 1 kg, fine soil or calcium magnesium phosphate seed dressing seeding. Broadcasting is not easy to control and generally not advisable. However, whether the seedlings or sowing must be applied to the base fertilizer, fertilizer per acre Shinong more than 1.5 tons or 40 kg of calcium magnesium phosphate is appropriate, it is best to use 25 kg of special fertilizer for grassland.
3, field management: special high ryegrass is characterized by hi wet and afraid of water immersion, therefore, field management should be tightly around the watering, fertilizing these two links. The basal fertilizer should be applied before sowing, and after the emergence, topdressing of 5-10 kg/mu urea or compound fertilizer in the 3-leaf stage or tillering stage should be performed to strengthen the seedlings. After each mowing, topdressing 10-15 kg/mu urea or compound fertilizer, and 3 to 5 days after mowing, in order to avoid burning grasshoppers, grass tips, causing decay. After the topdressing, timely irrigation should be carried out, and there should be drainage of stagnant water in the field in time to avoid rot disease.
4. Castration and utilization: seeding can be carried out after 45-50 days of sowing. When the first cutting is performed, it must be cut regardless of whether it is good or bad, and can not be lower than 3 cm to facilitate delivery. Later, depending on the situation of pasture, we will mow once every 20-30 days. If used to feed herbivores such as cattle and sheep, they should be harvested at the jointing stage to improve the quality of available dry matter. Due to the high moisture content of ryegrass grasses, if livestock and poultry are found to have “dilatory†phenomena, they can be harvested one day in advance and spread out after drying and wilting. This can be avoided.
Rye ryegrass cultivation method
Ryegrass is an excellent pasture with an eating rate above 95%. Because of its tenderness and succulence, it is a pasture variety that many livestock, poultry, and herbivorous fish like to eat. Therefore, it is widely used in animal husbandry.
