On July 21, more than 200 meat geese, big or small, took a leisurely stroll in the lush green ramie, and occasionally ate a few tender stems and leaves. Recently, modern agricultural industrial technology experts gathered in Changsha to observe the ecological meat goose breeding technology developed by the Institute of Materia Medica of the Chinese Academy of Agricultural Sciences. The expert group led by Liu Xu, an academician of the Chinese Academy of Engineering, believes that the technology can save about 50% of concentrate feeds while maintaining stable production performance, significantly reducing the cost of breeding.
Ramie is a special crop in China, but the traditional production of harvested fiber is the only product, and its original hemp accounts for less than 20% of the above-ground biomass. It is imperative to increase the use of ramie and broaden its industrial chain. The Institute of Materia Medica of the Chinese Academy of Agricultural Sciences has developed the first ramie variety “Zhongyouyu No.1†for feed, which has a crude protein content of more than 20%, and has strong regenerative capacity and large biological yield. Herbivore for more than 8 months. By integrating core technologies such as high-yield and high-efficiency ecological cultivation, grazing grazing, full-price feed, and resource recycling, this technology will increase the utilization rate of ramie resources from 20% to over 70%, giving full play to the feeding value of ramie. Achieving an efficient combination of planting and farming. Two years of trials have shown that 80 to 120 meat geese can be carried per acre of grass gardens per year. After adopting this technology, Ningyuan County’s professional cooperatives, which use the Qingbo-type Ma Yang Goose farmers, can earn at least 35 yuan more per goose than the goose fed the feed.
It is reported that in the multi-purpose use of hemp crops, the Institute of Materia Medica of the Chinese Academy of Agricultural Sciences has also made a number of research progress. In the past, silage mixed with unused hemp bone and hemp leaves has become a fertile ground for oyster mushrooms and beef. The mulch film and the hemp film also have obvious advantages.
