| 摘 要： | 在土壤瘠薄、盐碱较重的地段研究微肥、稀土对苜蓿产量及品质的影响,结果表明:喷施微肥及稀土对苜蓿有明显增产作用,200 g/kg稀土液产量最高,为16 708.40 kg/hm2,比对照高24.74%;施肥后粗蛋白含量明显提高,100 g/kg稀土液效果最好,两茬分别为22.14%、23.30%,比对照提高35.99%、30.75%;喷施微肥及稀土可增加苜蓿种植的经济效益,200 g/kg稀土液,净增收1 979.52元/hm2。

| Abstract: | The influence of trace element fertilizer and rare earth element on alfalfa's yield and quality was studied on barren,heavily salted place. The results indicated that: trace element fertilizer and rare earth element can raise alfalfa's yield,the solution of 200 PPM rare earth element is the highest,the yield is 16 708.40 kg/hm~2,higher than the antitheses 24.74%;the protein content of alfalfa raises after fertilizing,the solution of 100 g/kg rare earth element is obvious,the content of protein is 22.14%,23.30% respectively,more than the antitheses35.99%,30.75%;to raise the income of alfalfa plant,the solution of 200 g/kg rare earth element is the highest,being 1 979.52 yuan/hm~2. |
