对牧草蔗闽牧 4 2进行了不同行距、不同留茬高度和不同施N水平的比较试验。结果表明 ,综合各种因素以行距 50cm、留茬高度 5cm、施纯N 12 0kg/hm2 为最佳栽培技术方案。根据对不同时期肥料报酬率的探讨 ,还提出了闽牧 4 2“轻、重、重、轻”的施肥原则
A comparative experiment was conducted on the pasture grass cane Minmu 4 2 with different row spacing, different stubble height and different N levels. The results showed that the combination of various factors to row spacing 50cm, stubble height 5cm, Shi Chun N 12 0kg / hm2 for the best cultivation technology program. Based on the discussion of the rate of return on fertilizers in different periods, the paper also put forward the principle of “light, heavy, heavy and light”
