摘  要:
通过3年的试验、观测与分析,初步探明了禾本科牧草施用6种不同配方专用肥的效果。与施用常规复合肥相比,等价值施用牧草专用配方肥,单位面积的鲜草、干草产量分别提高8.3%—28.2%与5.2%—12.9%,干草中的粗蛋白质含量提高0.5%—7.6%;每公顷草地产出的营养物质数量,粗蛋白质增加5.0%—15.4%,粗脂肪增加2.6%—9.0%,无氮浸出物增加4.4%—10.2%。综合评价6种不同配方专用肥的施用效果,禾本科牧草专用肥的N、P2O5、K2O配比,以14∶6∶5或14∶5∶6的较为合理。

摘  要:
The effect of six formulae of compound fertilizer for gramineous grass was studied for three years(2000-2002).Compared with conventional compound fertilizer application,the special compound fertilizer(with the same value cost) got a higher yield of fresh qrass and dry grass per unit area,increasing by 83%-282% and 52%-129%,respectively.Furthermore,the contents of crude protein in dry grass were enhanced by 05%-76%,respectively,while the total amount of crude protein,crude fat and nitrogen-free extract of per unit area increased by 50%-154%,26%-90% and 44%-102%,respectively.The comprehensive evaluation showed that the optimum ratio of N,P2O5 and K2O is 14∶6∶5 or 14∶5∶6 for gramineous grass cultivation.
