Whatever the grass grassland people usually refer to, the grass is a wild grass that spontaneously extinguishes itself in its natural state. It is characterized by strong early spring germination, drought resistance, and resistance to earthworms, but it has low nutritional value, poor palatability, and low yield. The grass species now advocated refers to artificially cultivated forage quality herbages, characterized by weak early germination power and certain conditions for growth, but they have high nutritional value and high yield. For example, the high-yield, high-quality forage herbage chicory produces 10,000 to 20,000 kilograms of fresh grass per year and is rich in amino acids that are essential for many animals.
Wherever grasses of different species can be cultivated, the soil has different requirements. Saline-alkali land is only suitable for the cultivation of salt-tolerant pastures, such as sandgrass, ryegrass, and pods. In the orchard, interplanting must be done with shade-tolerant grasses, and neutral-alkaline soils are suitable for alfalfa, sand-dawn and so on. Acid soil suitable for planting red clover, white clover and so on. In hilly and lowland areas, where the soil quality is poor and the water resources are scarce, pastures that are resistant to flooding, drought, and good coverage should be planted, such as alfalfa, clover, tall fescue, and early maturing oysters.
Grasses do not need to be managed. Some breeders think that grasses do not need to be managed. As a result, pasture grass fields have less labor, thin fertility, poor seedling quality, and more weeds, which seriously affect the yield and economic efficiency of forage grasses. In fact, high-quality pastures, like rice, wheat, and cotton, have a whole range of scientific planting techniques. If grass is planted before the grass, the fields should be leveled and the soil fine. Since weed seeds have stronger germination power than pasture seeds, it is better to plant forage to select autumn sowing, so that they can accumulate nutrients in autumn and winter, promote spring growth, and strengthen weeding (weeds) at the initial stage of emergence to prevent weeds from forming. climate. Pasture also needs fertility support, so pay attention to fertilization. Therefore, planting pastures should strengthen field management in the growing season like rice, wheat, and cotton, so as to obtain expected benefits.
Pasture has low nutritional value The nutritional value of pasture is really better than that of rice, wheat and corn. Answering this question must be based on scientific analysis. Scientific analysis shows that forage grass has comprehensive nutrition, good palatability, and easy to digest. For example, alfalfa hay contains 14%~18% of crude protein, is higher than rice (8.3%~8.5%), wheat (10.8%~12.1%), and corn ( 8.6%). In addition, pasture is also rich in many kinds of vitamins and minerals, which is beyond rice, wheat, corn.
The purpose of planting grass is to grazing farm areas. After all, it is different from pastoral areas. Grazing grass is not suitable. In terms of feeding methods, instead of using grass substitutes, certain concentrates must be added to supplement the nutritional deficiency of pasture. In terms of feeding requirements, different livestock and poultry require different forages. For example, fresh grasses for pigs and geese must be cut short. Fresh grass for cattle and sheep should not be too short. Fresh grass for feeding rabbits should not carry water. , Hay feeding pigs, birds with grass powder is appropriate. Different breeds of animals have different requirements for pastures, such as ryegrass, alfalfa, milk vetch, arrow peas, and pine cone herb, which are suitable for feeding various types of livestock and poultry. Sudan grass and pennisetum are suitable for feeding cattle. Sheep and other grass animals and fish. In addition, the cultivation of livestock should be scientifically measured to ensure the maximum efficiency of planting and breeding. For example, each cow needs to plan to plant 1.5 mu of pasture, and planting 1 mu of ryegrass can raise about 150 vegetable geese or about 10 sheep. What must be reiterated here is that the proportion of planned grass-raising and livestock-raising is based on the season of high forage grass production.
The efficiency of grass is not high. Because it is difficult to commercialize pasture in a short period of time, it is difficult to achieve the benefits only by planting grass, but if grass is combined with livestock, the potential benefits of pasture can be effectively transformed and Value-added. According to the survey, the conversion of wheat and rice to two crops for forage grass crops, the development of dairy cows, can add 1476 yuan per mu.
