硼、锰、钼对紫花苜蓿生产性能的影响

The Effect of Boron, Manganese and Molybdenum on Alfalfa Production Performance

本试验研究了硼、锰、钼单施或配施对紫花苜蓿生产性能的影响。结果表明：硼、锰、钼单施或配施可以显著地（P〈0．05）增加苜蓿草层高度、提高干草产量和种子产量。尤其以硼、锰、钼3者配施株高、干草产量和种子产量最高，株高达76．3cm，比对照（CK）草层增高29．3％；干草产量达9993．7kg／hm2，比对照（CK）增产37．3％；种子产量达206．7kg／hm2，比对照（CK）增产34．4％。

In this article the effect of Boron, Manganese, and Molybdenum on alfalfa production Performance is described. The results showed that either individual application or combined application significantly （P〈0.05） increased grass layer height , dry grass yield, and seed yield. The effect was greatest with respect to plant height ,dry grass yield, and seed yield when combined of three fertilizers were applied. Plant height reached 76.3 cm, an increase of 29.3% as compared to the control; the yield of dry alfalfa was 9993.7 kg/ha, an increase of 37.3% compared to the control; seed yield was 206.7 kg. /hm2 , an increase of 34.1% compared to the control.
