Ryegrass is soft and juicy, and is eaten by a wide range of livestock, poultry, and herbivorous fish. The feed intake is above 95%. During the vegetative growth period, 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, an average of 24 kg of fresh grass can raise 1 kg of live rabbits, 20 kg of fresh grass can increase 1 kg of live geese, and 18 kg of fresh grass can produce 1 kg of livestock. Fish, 28 kg of fresh grass can increase 1 kg of live lamb. One acre of high-lying ryegrass has more than 100 geese in winter. According to tests 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 add 1 kg of fresh milk. Ryegrass can also increase fertility and promote post-crop growth. According to the test of Professor Yang Zhongyi of Sun Yat-Sen University, planting multi-flowered ryegrass in winter slack field can also increase soil fertility, increase soil organic matter by 27.1%, increase available nitrogen, phosphorus, and potassium by 11%, 25.5%, and 57.2%, respectively. The volume increased by 38%, and the post-planting of rice was significantly improved in plant height, panicle length and 1000-grain weight, and the average yield was increased to 10%. Grassland seed industry, grassland ecological construction, animal husbandry, forage and forage production, landscaping, water and soil conservation, technology development and technical consulting, business services, the main business of Yunnan Lusheng Midland Technology Industrial Co., Ltd. operates Ryegrass, a tetraploid 1-year-old ryegrass cultivated for the US Green Group, is characterized by good cold resistance, low lodging, rapid germination, rapid regeneration, and high yield. Its seedling growth is very strong. After 45 days of sowing, the first fresh grass can be harvested, and then it can be cut once every 15 days. The test results in Yunnan indicate that the area below 1800 meters is suitable for sowing after rice is harvested, and can produce more than 7 tons of fresh grass per mu within 5 to 6 months before planting rice in the coming year; the middle altitude area (1800-2100 meters), It can be planted in summer and autumn, and can be cut and used for many years. The annual output can reach more than 20 tons. First, sowing time. After many years of practice, the suitable sowing date for low-lye ryegrass in Yunnan is from late August to late September, that is, after the rice is harvested, it is ploughed and sowed. It is suitable for summer sowing in an area with an altitude of over 1,800 meters, and the sowing time is 5 From the month to the end of June (the rain is suitable for a week). Second, sowing method. There are two kinds of methods for sowing ryegrass, that is, no-tillage sowing and tillage 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. Third, field management. Ryegrass is characterized by its high level of sensibility and fear of water immersion. Therefore, field management should be closely linked to watering and fertilizing. Before planting, sufficient basal fertilizer should be applied. Conditional farmers should apply 5-10 kg/mu urea or compound fertilizer to seedlings at the 3-leaf stage or tillering stage after emergence. After each mowing, topdressing 10-15 kg/mu urea or compound fertilizer, and 3-5 days after mowing, so as not to burn grasshoppers, grass tips, causing rot. 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. Fourth, castration use. After 45-50 days of sowing, it can be castrated. When the first time the grass is cut, it must be castrated regardless of whether it is good or bad, and it must not be less than 3 cm in order to facilitate the tillering. 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. In order not to affect the production of post-cropping rice, 15 days before transplanting, plowing will be conducted after the harvest, and 15-20 kg of lime will be sprinkled per acre to accelerate decomposition of grass roots. 3 Layers Earloop Disposable Face Mask Bacteria Protection Face Mask,3 Ply Breathable Face Masks,3D Stereo Face Mask,3 Layers Earloop Disposable Face Mask Dongguan Keyutai Mask Co., Ltd. , https://www.maskkytai.com
