黑麦草 (IRG)的栽培方式、播种量、施肥种类和施肥量是影响 IRG优质高产的主要因素。研究结果表明 ,高播量 (2 2 .5kg/hm2 )稻底撒播方式可以获得优质高产的 IRG,干物质产量 9183.4 5kg/hm2 ,粗蛋白质产量达 16 6 8.0 0 kg/hm2 ,因其节省劳力 ,且可以有效利用稻田水分 ,因此可作为稻田冬种 IRG的主要方式。中等播量 (15.0 kg/hm2 )育苗移栽方式也获得了较高的产量 (976 5.4 5kg/hm2 )和最高的 IRG粗蛋白质产量 (1730 .2 5kg/hm2 ) ,尽管该方式花费劳力较多 ,但节约种子并可以提早供草 ,可根据生产需要加以运用。在施肥管理上 ,使用复合肥 (N∶ P2 O5∶ K2 O=15∶ 15∶ 15) 150 0 kg/hm2的施肥管理方式最佳 ,应尽量避免单施尿素
The cultivation methods, seeding rate, fertilization type and fertilizer rate of ryegrass (IRG) are the main factors that affect the yield and quality of IRG. The results showed that IRG with high yield and high yield (22.5kg / hm2) could be obtained with high yield and good quality, dry matter yield was 9183.4 5kg / hm2, crude protein yield was 16 6 8.0 0 kg / hm2, , And can effectively use paddy field moisture, it can be used as the main form of winter rice IRG. The higher yield (976 5.4 5 kg / hm2) and the highest yield of IRG crude protein (1730.225 kg / hm2) were also obtained for medium sowing (15.0 kg / hm2) seedling transplanting, although this method was labor intensive , But save seeds and can be early grass supply, according to production needs to be used. Fertilization management, the use of compound fertilizer (N: P2 O5: K2 O = 15:15:15) 150 0 kg / hm2 fertilization management is best, should try to avoid urea alone
