Expert suggestion: forage can replace grain for animal husbandry in China (10.31)

OA show ('918 '); on the 26th, many experts at the International Symposium on the comparison of Chinese and foreign agricultural modernization held here suggested that forage could replace grain with grass in China's animal husbandry Experts agree that the situation that animal husbandry uses a large amount of food is an important reason why China still cannot be optimistic about the supply of rations With the increase of income level, the per capita direct consumption of rations in China has been decreasing at an average annual rate of 1-2kg, and this trend will continue The reduced rations could have provided enough for the new population in the future However, as feed grain now consumes about 30% of the total grain output, the government still has to be nervous about the problem of "food security" Not only that, Huang Qinghe, an expert from the development research center of the State Council, also pointed out that grains are obtained from scarce cultivated land and fresh water resources, and it is also uneconomical to use large quantities of grains as feed Since the late 1980s, experts have begun to study the transformation of planting structure from the dual structure of "grain + economic crops" to the triple structure of "grain + economic crops + feed crops" However, because the third element of "feed crop" is competing with grain for area and output, it conflicts with the original agricultural management objectives and performance evaluation indicators, which makes it difficult to implement In recent years, some provinces in the southeast coast of our country have begun to use non cultivated land to grow forage Guangdong Province introduced legume forage from Australia and planted it among hills and mountains In five years, the area has reached more than 60000 hectares, making up the gap of feed grain of 1-1.5 million tons The winter wheat planted in Fuyang City, Zhejiang Province, has a lot of rain at maturity, low yield and poor quality, but its branches and leaves are very lush After calculating the account, the farmers simply cut the wheat in batches and fed it to the cattle in stages to develop the dairy industry, and the benefits are greatly increased Experts pointed out that in the future, China's grain production mainly depends on cultivated land, and the number of cultivated land is very limited However, there are various countries in China that can provide various forms of feed nutrients The area of grassland and Grass Mountain is about 400 million hectares, which is three times of the cultivated land The potential of intensive management is huge Another part of the "grain for grass" arable land can also become a new pasture The authoritative investigation and analysis also found that although the nutrients of various grasses are different and the digestion ability of animals is also different, it can be generally calculated and replaced by one kilogram of grain per 10 kilogram of green feed Then, it is possible to double or even more the expected output rate of the land when planting appropriate forage crops than when planting grains Moreover, compared with grain cultivation, forage has a stronger adaptability to bad weather, and its growth is less limited by land resources Therefore, experts believe that no matter from the perspective of China's land and resource structure, land productivity, or the type of Forage Nutrition of cultivated land, China's Forage structure can minimize its dependence on food, focus on the development of herbivores, and drive the development of artificial green forage industry, so as to slow down the pressure of food and improve the utilization rate and efficiency of land China feed industry information network KDU (author:)
