How to choose the suitable grass species
With the deepening of the structural adjustment of animal husbandry and the need to control the cost of livestock and poultry farming, pasture cultivation has gradually been valued by a large number of farmers. In the face of numerous advertising campaigns for the species, the introducer must not havetily introduce some pasture without a thorough understanding. What kind of pasture is suitable for planting, but also a comprehensive consideration of livestock breeding species, local climate conditions and soil conditions and other factors.
1, according to the selection of livestock and poultry breeding species. Different livestock and poultry breeds have some differences in feeding characteristics, nutritional needs, etc. The first consideration is the pasture that is suitable for their own cultured species. In general, ruminants prefer to eat high-grass, relatively large amounts of crude fiber content of pasture, such as forage corn, Emperor bamboo grass, Sudan grass, Leymus chinensis, Bromus, Elymus, Stellariae, etc., Among them, Sudan grass is particularly suitable for raising dairy cows. Its fresh stems and leaves are also excellent forages for fish farming; pigs, chickens, geese and rabbits prefer pastures with high protein content and tender leaves, such as Rumex K-1. Hybrid sorrel, chicory, comfrey, white clover, red clover, etc. In addition, alfalfa, winter grazing - 70 rye, ryegrass, etc. are suitable for all livestock and poultry, and ryegrass is also a good forage for fish farming. Grain pods are more suitable for raising pigs, bitter leeks are more suitable for geese.
2, according to the geographical and climatic conditions. The growth of pasture requires a suitable climatic condition and regional scope. If grass is planted in violation of natural laws, its growth ability will decline or even fail to grow. In cold regions, it is possible to plant cold-resistant alfalfa, converging grass, Rumex K-1 hybrids, alfalfa grass, Dongmu-70 rye, bromegrass, schisanthin, and sandgrass; drought The area can be planted drought tolerant alfalfa, sudan grass, sand chaowang, grain alfalfa, Rumex K-1 hybrids, L. chinensis, Bromus, Elymus, etc.; hot areas can be planted Herbs such as vanilla, sudangrass and bitter leeks are not suitable for planting awnless bromegrass, elymus, white clover, red clover, and synthetic grass; in warm and humid regions, ryegrass, sudangrass and forage maize can be grown. White clover, red clover, pine cone herb, bitter leeks, grassy grass, elephant grass and so on.
3, according to the selection of soil geology. Pasture is closely related to the soil on which it relies, and the introduction of pasture requires full consideration of the local soil geology. Alkaline soil can be considered to introduce alkali-resistant alfalfa, winter grazing -70 rye, pine cone herb, sand wangwang, Rumex K-1 hybrids, grass hibiscus, sudan grass, yew, osmotherium Wheat, Elymus, etc.; acidic soil can be introduced acid-resistant series of pine cone herb, white clover, etc.; barren soil can be introduced to the poor and resistant sand-wang, alfalfa, grass, alfalfa, Bromeless, Elymus, etc. The species with high soil moisture may be selected from white clover, red clover, turfgrass, and Elymus genus, but alfalfa, yew, grass, etc. should not be planted.
4, a variety of pasture complementary options. One is that grasses are mixed with leguminous pastures. 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, when feeding ruminants, it can also prevent the occurrence of hernia caused by eating a single legume grass. Commonly used combinations include: Festuca arundinacea + white clover or alfalfa, ryegrass + clover, sudan grass + red clover, bromegrass + alfalfa, grass hibiscus + ryegrass, etc.; second, different growing seasons The pastures are paired with varieties to achieve long-term supply of grass. In the warm spring, you can choose to use ryegrass, red clover, white clover, alfalfa, etc. In the hot summer, you can choose to use sudangrass, chopped pine herb, bitter leeks, etc. In the cold winter, you can choose to use winter Grazing - 70 rye, or silage and hay.
5. Combine local resources development options. The agricultural resources in various parts of China are abundant, and their potential for utilization is huge. If we consider the combination of local resources development when planting pastures, we can often avoid unnecessary construction and produce comprehensive development benefits that can do more with less. In areas rich in wild grasses and convenient in use, it is possible to reduce or eliminate the need to artificially grow pastures; when wild grasses are mainly used for grasses, some leguminous grasses can be properly planted; wild grasses can be used mainly for legumes, such as ruminants Some gramineous forage grasses can be properly planted; when silages such as milk vetch, potato stems, squash vines, and watermelon vines are to be silaged, they can be enriched with fodder corn, ryegrass, Sudan grass, etc. Carbohydrate herbage prepared for mixed silage. When planting pasture projects, consider cooperating with units or experts with scientific research strength to avoid being taken or detours.
