Barley green plant refers to the general term for the green biomass material on the ground after the emergence of barley to the late maturity. With the deepening of the structural reform of the agricultural supply side, the traditional consumption pattern of barley grain is far from meeting the needs of the development of herbivorous animal husbandry in the agricultural area. According to the results of research on barley green feeding technology in recent years and the practice of popularization and application in various places, the Institute of Agricultural Sciences of the Provincial Academy of Agricultural Sciences summarized the utilization methods and techniques of grazing, silage and hay modulation of barley green plants.
Barley seedlings
After sowing in autumn, barley grows fast, has many tillers, and is resistant to grazing. It is a high-quality grazing pasture and one of the grasses with high yield of digestible material in grasses. Often unicast or mixed with a variety of pasture crops, legumes such as milk vetch, white clover, red clover, medlar, medlar, broad beans, peas and so on. Cattle, sheep and horses especially like to mix grass, not only increase the length of meat, but also produce more milk. According to the practice of Maanshan and other places in our province, cattle, sheep, geese, etc. can be grazing once in about 1 month after the barley is planted and emerged. After that, it can be grazing every 20 days or so. It can be grazing about 5 times before the Spring Festival. The grazing adopts the method of rotational grazing, which should be carried out in zones to prevent repeated grazing. The feed intake per grazing is controlled to be 60%-70% of the total amount of fresh grass. Generally, about 10 sheep can be grazing per acre. After each grazing, it is necessary to topdress 3-5 kg ​​of urea per acre. In the southern part of Huanghuai and the middle and lower reaches of the Yangtze River, grazing continues until the second half of February of the following year, and the barley is stopped after the jointing of barley, and in the late stage of milking, the barley, silage and hay can be prepared according to the needs. The use of barley grass for grazing is suitable for small and medium-sized herbivorous livestock and poultry farms and family farmers.
Barley green plant silage
Barley green plant silage can solve the problem of seasonal imbalance and regional imbalance in supply and demand. It can also solve the difficulty of preparing hay in the rainy season of mid-southern forage in China, and obtain silage with better quality than barley corn. material. Silage should be castrated in the middle and late stages of milk ripening and cut into sections 3-5 cm, which should be stored while cutting. If silage is in advance and the water content of barley plants exceeds 75%, dry matter such as soybean dry straw, peanut dry straw, and bran should be added. The fermented silage barley feed has a strong aroma of sweet and mellow fruit and is the best winter and spring feed. Barley silage is suitable for large-scale breeding of cattle, horses and sheep.
Barley green plant hay making
The hay made from green plants in the middle and late stages of barley growth, yellow-green color, aromatic smell, good palatability, high protein and low crude fiber, can provide high quality roughage in winter and spring. In combination with the application practice, in sheep breeding, it is generally possible to choose a sunny day of cutting at the end of the booting stage to the beginning of the heading, and spread it on a thin layer for more than 3 days, and when the water content is below 15%, it will be piled into a pile or made into a grass block. , grass cakes, etc., for winter and spring feeding. If conditions permit, it can also be made with the aid of drying equipment. This method of brewing barley hay is particularly suitable for feeding ewes. In the breeding of cattle, horses, sheep, etc., if the varieties of the toothed barley are delayed, the hard and difficult to digest may lead to a decrease in palatability. Therefore, the hay production should be carried out before the heading stage; no mang, hook, and light barley varieties Hay production can be carried out from the heading stage to the mid-milk stage. The barley green plant is made of hay and is suitable for breeding cattle, horses and sheep of various scales.
