Wandering through the fields, you will find a verdant ocean, that is, Gaodan grass. Godangrass is a high-quality forage that is characterized by rapid growth, high yields, and rich nutrients. Gaodan grass, also known as hybrid Gaodan grass, is the latest hybrid combination of forage sorghum and Sudan grass after multiple generations of selection, and also combines the common advantages of both, not only retaining the characteristics of tall, thick stem, wide leaves and high sugar content of sorghum, but also absorbing the advantages of sultan grass tillering power, strong regenerative power, large leaf amount, low lignin content and so on. When it comes to field management, Gaodan grass also has its own unique features.
First of all, the growth rate of Gaodan grass is very fast, generally after spring sowing, it only takes about 50 days to reach the harvest period, and then every 20 days or so can be harvested again. In order to ensure the high yield of fresh grass throughout the year, therefore, in the field management, it is necessary to pay attention to timely harvesting, so as not to overgrow and lead to a decrease in nutritional value, top dressing after each harvest, and urea 8-10 kg per mu can be topdressed. At the same time, the growth of Gaodan grass also needs sufficient sunlight and water, so it is necessary to pay attention to irrigation and fertilization during field management to ensure the growth quality of Gaodan grass.
Secondly, the yield of Gaodan grass is very high, which can be harvested 4-6 times a year, and the yield per mu can reach more than 5000 kg. This also means that when managing the field, attention needs to be paid to timely harvesting and storage to avoid waste. When feeding large animals like cattle and sheep, harvesting at a plant height of about 1.5 meters, this time palatability is good, cattle and sheep eat is good digestion and absorption, if used as small animals such as rabbits, geese, ostrichs and other animals, can be harvested at a plant height of 70-100 cm, this height can be harvested 8-10 times throughout the year. At the same time, the yield of Gaodan grass also needs to match the number of livestock to avoid excess or underage.
Finally, the nutritional value of high dangrass is very rich, rich in protein and minerals, crude protein content can be as high as 8%-15%, crude fat is higher than Sudan grass and sorghum, the leaves are wide and long, the leaves are tender. The stems are sweet and palatable, can be harvested directly and fed, and can also be used for silage or blended into hay, so it is necessary to pay attention to protecting the nutritional value of Gaodan grass and avoiding excessive loss in field management. At the same time, it is also necessary to pay attention to the reasonable combination when feeding livestock to ensure the health and production performance of livestock.
Finally, once again remind everyone to pay attention to the need to pay attention to the fact that Gaodan grass seedlings contain the toxic substance hydrocyanic acid, so before the height of 50 cm, do not graze or green feed, to prevent hydrocyanic acid poisoning, each feeding livestock do not let livestock eat on an empty stomach, to prepare sufficient water to supplement salt or minerals, which can reduce the harmful effects of hydrocyanic acid, in the process of silage or preparation of hay, most of the hydrocyanic acid volatilizes, so it will not cause livestock poisoning, can be eaten with confidence.
In short, Gaodan grass is a high-quality forage that is characterized by rapid growth, high yield, and rich nutrients. In terms of field management, attention needs to be paid to timely harvesting, irrigation and fertilization to ensure the growth quality and yield of Gaodan grass. At the same time, it is also necessary to pay attention to protecting the nutritional value of Gaodan grass and feeding livestock reasonably to ensure the health and production performance of livestock.
