“林草、果草间作技术”是利用林业和果业田地的空闲土地,见缝插针,进行人工种植牧草。据山东烟台资料,间作的紫花苜蓿,1年可收割8茬,干草亩产高达1100.56公斤,平均亩产干草723.5公斤,干草中蛋白质含量达17～22%;每亩苜蓿蛋白质含量达17～22%;每亩苜蓿含蛋白质128公斤以上,相等于1600公斤玉米或320公斤花生饼中蛋白质的含量。用苜蓿草代替部分饼类饲养畜禽费用降低40%以上,而且苜蓿根瘤有固氮养地之用,每亩苜蓿固氮含量相当95公斤标准氮肥,较好地改良
“Forest grass, intercropping technology” is the use of forestry and fruit fields of idle land, see the pin, artificial cultivation of forage. According to Shandong Yantai, alfalfa intercropping, harvesting 8 crops a year, hay yield as high as 1100.56 kilograms, an average of 723.5 kilograms of hay per mu, hay protein content of 17 to 22%; alfalfa protein content per acre up to 17 to 22 %; Alfalfa per acre containing more than 128 kilograms of protein, equivalent to 1600 kg of corn or 320 kg of peanut cake in the protein content. Alfalfa grass instead of replacing part of the pie to reduce the cost of livestock and poultry more than 40%, and alfalfa nodules are used for nitrogen fixation, nitrogen per acre of nitrogen equivalent to 95 kg of standard nitrogen fertilizer, better improved
