Technical Tips for Farming Rafts in Mountain Areas (1)
In Yangshan County, Guangdong Province, which introduced breeding in 2000, some farmers have achieved poverty alleviation through breeding of alfalfa, but some farmers have suffered serious losses from breeding. In order to find out more about the adaptability of alfalfa farming in mountainous areas and the main points of its breeding techniques, the county science and technology department conducted research and technical guidance for most of the county's farmers. According to our experience, the following technical points must be mastered in mountain farming: First, the venue selection is perfect, and you like to dance and roll on a wide field. Under artificial breeding conditions, there must be enough sports venues and require good drainage, and no water accumulation, so as to avoid unhealthy water and cause illness. The site is selected to be flat or slightly sloped in the south or southeast direction. The soil is preferably loam or sandy loam. It is far from the village and it is easily accessible. There are no other livestock and poultry farms nearby to avoid the cross-contamination of diseases. The sheds should be well ventilated, easy to clean and disinfect, and each 100 rakes should have a shed of 100 square meters and a playground area of ​​250 to 300 square meters. Second, feed requirements 1. Concentrated feed: to meet the nutritional requirements of various stages of earthworms, crude protein content needs to reach about 17% to 20%, metabolic energy of 2650 ~ 2700 kcal / kg. 4 to 6 months of age for the long shelf phase, should increase protein, calcium, phosphorus and vitamin D supplement. Pay attention to the quality of raw materials. Peanut bran and minced meat should be fresh and must not be fed mildewed feed. 2. Green fodder: It is better to use forage grass, black grass, grassy grass and leguminous weeds, bamboo grass, cattle hay, water lotus, Fanzmiao, twigs, leaves, etc. can also be fed . If a variety of green materials can be mixed and fed, it will help enhance the disease resistance of alfalfa.
