人工种植牧草作为农业结构调整、农民增收的重要途径在全国各地得到较大面积推广。目前一些报刊对牧草的品种、栽培技术报道较多,一些农民朋友对刈割与调制知识知之较少。笔者对此作一简单介绍。一、牧草的刈割1.适宜刈割期:牧草应确定在单位面积营养物质总收获量最高时期进行刈割。禾本科牧草宜在抽穗到开花期刈割,豆科牧草宜在现蕾或初花期刈割。2.刈割高度:刈割过高,会降低产量;刈割过低,会影响牧草再生能力。一般上繁草刈割可高些,留茬5～6厘米;下繁草应低些,4～5厘米。土壤、气候条件好、管理水平高的地方刈割可低些,反之应高些。冬前最后一次刈割留茬10厘米左右,以利安全越冬。3.刈割次数:多年生牧草一年要刈割几次,因 Artificial planting of forage as an important component of agricultural restructuring and an important way for farmers to increase their incomes has been widely promoted across the country. At present, some newspapers and periodicals have reported more on pasture varieties and cultivation techniques, and some farmers’ friends have less knowledge of cutting and modulation. I make a brief introduction to this. First, the pasture grazing 1. Suitable for the cutting period: pasture should be determined in the highest per unit area of ​​total nutrient harvest for cutting. Grass grasses should be heading to the flowering flowering mowing, legumes should be cut or flowering in early flowering. 2. Cutting height: cutting too high, will reduce the yield; cutting too low, will affect the forage regeneration capacity. In general, the mowing of cutting grass can be higher, stubble 5 ~ 6 cm; under the grass should be lower, 4 to 5 cm. Soil, good climatic conditions, high levels of management cutting can be lower, on the contrary should be higher. The last mowing before winter stubble 10 cm or so, in order to facilitate safe winter. 3. Mowing times: perennial grass to mow a few times a year, because
