According to the climate characteristics, select different varieties of pasture to adapt to different climatic conditions and regional scope. Cold areas can choose to plant cold-resistant alfalfa, Conghua grass, Rumex, grass hibiscus, winter grazing 70 rye, bromegrass, schisandra herb, sand wang, etc.; dry areas can be planted drought-resistant purple flowers Grasshoppers, Sudangrass, Sandaldgrass, Graingrass, Rumex, Leymus chinensis, Bromegrass, Elymus, etc.; hot-spotted pine herb, Sudangrass, bitter leeks, etc. may be grown in hot regions, but not suitable for planting Bromegrass, Elymus, Trifolium repens, Red clover, Synthetic grass, etc.; Ryegrass, Sudan grass, fodder corn, Trifolium repens, Red clover, Perfoliaceae, and bitter herbs can be grown in warm and humid regions. Leeks, grasses, grasses, etc. According to the type of soil, choose neutral alkaline soil suitable for planting strong alkali-tolerant varieties, such as alfalfa, sand, etc.; neutral acid soil suitable for planting strong acid-resistant varieties, such as red clover, white clover; Saline-alkali land is only suitable for planting salt-tolerant varieties, such as sandgrass, ryegrass, seed pods, leymus, alkali grass, sudan grass and so on. According to different uses, for the purpose of harvesting green forage, one should select a cultivar that has good growth in one year or two, early growth, high short-term harvest, and sensitivity to fertilizer effects, such as alfalfa, Dongmu 70 rye, red clover, and white three. Leaves, grass, Rumex and so on. If a certain area is planted for grazing, priority should be given to high-reproductive, high-density varieties such as perennial ryegrass, Dactylis, clover, Festuca arundinacea, and oxtail grass while considering high yields. Due to the large feed intake of pigs, it is required to have a low cellulose content in feeds, rich in carbohydrates and protein, and it is better for pig farmers to grow seed grains, feed vegetables, and Rumex, as well as chicory and feed corn. According to the preference of different livestock and poultry, different livestock and poultry have different palatability, and the poultry feed intake is small. It requires high protein content and less cellulose feed. It is better to plant bitter leeks and grains. Chickens should be based on bitter leeks; there are many varieties of pastures suitable for raising geese, with good palatability, high alfalfa production, such as alfalfa, winter grazing 70 rye, ryegrass, sudangrass and bitter leeks. Buckwheat palatability is best. Cattle and sheep have a large demand for feed, and have a strong ability to digest crude fiber. They should use high-yield, grain-feeding-cum-purposes and pastures such as Zigu, Yugu, Sudangrass and alfalfa, red bean grass, sand and woodgrass. Wait. In the future, the development of herbivores (cattle, sheep, etc.) will be implemented with more housing. The demand for forage grass feed will be more urgent and the selection of grass will be more scientific and reasonable. It is best to use the hay to grow cereals; use grass, it is best to plant alfalfa. In summer and autumn, the grass is fed in the form of 2:2 fodder corn and grain pods. After the autumn, corn stalks and grain pods are mixed with silage, and the cattle and sheep are fed in winter and spring. For dairy cows and dairy sheep, try to choose feed crops with high moisture content, high sugar content, and high protein content, such as grain sorghum, schizophyllum herb, and planted sweet sorghum and feed vegetables. Rabbits are omnivorous animals, require feed moisture, and contain a certain amount of cellulose, should be planted yarrow, cereals, and high-protein feed crops, such as grains, buckwheat, alfalfa, red bean grass, chicory and so on. A variety of grasses complement each other with a choice of grass and legume grass mix and match. With this method of sowing, the roots and leaves of the two grasses are distributed differently and the nutrients absorbed are also different. Grasses can also use the nitrogen provided by the legume legume rhizobia, thus significantly increasing pasture yield. At the same time, in the pasture field, when ruminants are grazing, they can also prevent the occurrence of airway disease due to the intake of single legume grass. Commonly used mixtures are: Festuca arundinacea and white clover or alfalfa, ryegrass and clover, sudan grass and red clover, bromegrass and alfalfa, grasses and ryegrass. The second is the matching of pastures in different growing seasons to achieve constant supply of grass. In the warm spring season, ryegrass, red clover, white clover and alfalfa can be used. In the hot summer, you can choose to use sudangrass, herb leaves, bitter leeks and so on. In the cold winter, you can choose to use winter grazing 70 rye or silage and hay. Combining local resource development options in areas where wild grasses are abundant and easy to use can reduce or eliminate the need for artificial pastures; when wild grasses are mainly used for grasses, some leguminous pastures can be properly planted; wild grasses can be used mainly for legumes At the same time, if ruminants are raised, some grasses may be properly planted; if silages such as milk vetch, potato stems, squash vines, and watermelon vines are to be silaged, forage maize and ryegrass may be planted. , Sudan grass and other carbohydrate-rich pasture to prepare mixed silage.
