白三叶草(Trifolium repens Z),在我省海拔1000米左右的山区种植,生长很好。在低海拔丘陵种植,夏秋干旱时,适时灌溉,也能获得理想的产量,是我省重点推广的优质高产豆科牧草之一。为探明化肥对豆科牧草的增产效益,我们对白三叶草进行了增施钾肥的试验,取得了显著的经济效益。 White clover (Trifolium repens Z), grown in the mountainous areas around 1000 meters above sea level in our province, grow very well. In the hilly low altitude planting, summer and autumn drought, timely irrigation, but also to obtain the desired yield, is the focus of our province to promote high-quality and high yield legumes. In order to find out the benefits of chemical fertilizers on the yield increase of leguminous forage grass, we conducted the experiment of increasing potassium fertilizer on white clover and achieved significant economic benefits.
