紫花苜蓿是优良的豆科牧草,含蛋白质14—21.0％和多种维生素,是牲畜优良饲料,具有“牧草之王”的美称。苜蓿具有根瘤,能固定空气中的氮素,是改土肥地、轮作倒茬的重要绿肥作物。新疆种植苜蓿的历史悠久,是我国苜紫种植面积较多的省区之一。很多地区长期以来苜蓿种子产量很低,一般亩产只几公斤,有的地区苜蓿长势很旺,覆盖度大,花也很多。但留种时常常收不到种子。为了提高苜蓿种子产量,近几年来我们进行了试验及调查研究,现就提高苜蓿种子产量提出下列意见。
Alfalfa is an excellent leguminous pasture, containing 14-21.0% protein and a variety of vitamins. It is a good feed for livestock and has the reputation of “King of Forage”. Alfalfa has nodules, which can fix the nitrogen in the air. It is an important green manure crop that turns soil into fertilizer and turns crop rotation. Xinjiang has a long history of planting alfalfa, which is one of the provinces and autonomous regions in China with more alfalfa planting area. In many areas, the yield of alfalfa seeds has long been very low, generally only a few kilos per mu. In some areas, alfalfa grows very well with large coverage and lots of flowers. However, often not receive seed when you stay. In order to improve the alfalfa seed yield, we have conducted experiments and investigations in recent years, and now we put forward the following opinions on improving the alfalfa seed yield.
