牧草是放牧地和采集地中,以禾本科和豆科牧草为主,供放牧和刈割的草类。日本的牧草都是从国外引入的,和当地的野草截然不同。由于来源和栽培区域环境条件的差异,可分为寒地型牧草和暖地型牧草。牧草应具备的特性为多年生,再生力强、喜光抗寒,保持水土,改土肥田,饲料价值高,生产性能良好。多年牧草的栽培原则是选择优良品种,合理施肥,细致镇压,充分利用抗寒性,合理放牧和刈割。栽培的是牧草,围绕着牧草的是环境,大气环境的主要因子是温度,水分和光照。寒地型牧草0℃就能发芽,最高发芽温度35℃,出苗后20—25℃发育最好,而暖地型牧草10℃以上才能发芽,35℃以上发芽良好,出苗后
Pasturage is grasses and legumes grazing grass and mowing grasses in grazing lands and gathering grounds. Japan’s pastures are imported from abroad, and the local weeds are completely different. Due to differences in environmental conditions between source and cultivation areas, it can be divided into cold-type grass and warm-type grass. Herb should have the characteristics of perennial, strong regeneration, hi light cold, soil and water conservation, soil fertilizer, feed high value, good production performance. Years of forage cultivation principles is to choose good varieties, rational fertilization, careful suppression, take full advantage of cold hardiness, reasonable grazing and cutting. Cultivation is pasture, around the pasture is the environment, the main factors of the atmospheric environment is temperature, moisture and light. Cold pasture can germinate at 0 ℃, the highest germination temperature is 35 ℃, the best is 20-25 ℃ after emergence, whereas the warm pasture can germinate more than 10 ℃, germinate well above 35 ℃,
