多年生黑麦草喜温暖湿润的气候,适于年降水量1000～1500毫米的地区,生长最适温度为20℃,不耐炎热,抗旱性差。多年生黑麦草要求肥沃、湿润和排水良好的壤土和黏土,也可在微酸性土壤中生长。多年生黑麦草发育迅速,一般寿命4～5年,因此要种植和利用好多年生黑麦草,解决好越冬是关键。适时收获确定多年生黑麦草的收获适期,不仅要考虑到黑麦草的产量和品质,同时还要考虑到有利于多年生黑麦草的越冬。一般情况下,收获后应该有1个月以上的生长期,才有利于多年生黑麦草的安全越冬。合理的留茬高度最后一茬多年生黑麦草收获时的留茬高度直接影响到再生草的生
Perennial rye like warm and humid climate, suitable for annual precipitation 1000 ~ 1500 mm region, the optimum growth temperature of 20 ℃, intolerant of heat, drought resistance is poor. Perennial ryegrass requires fertile, moist and well-drained loam and clay, and can also grow in slightly acidic soils. Rye perennial development is rapid, the general life expectancy of 4 to 5 years, so to grow and make good use of many annual ryegrass, to solve the winter is the key. Proper harvest Harvest of perennial ryegrass is determined not only by the yield and quality of ryegrass, but also by the wintering of perennial ryegrass. Under normal circumstances, after harvest should be more than 1 month of growth, it will help perennial safety of perennial grass winter. Reasonable stubble height The stubble height at harvest of the last crop of perennial ryegrass directly affects the growth of regenerated grass
