苜蓿温室扦插,国外巳有报导。本文是在甘肃农业大学牧草站接近大田条件下扦插进行试验的.试验结果指出:苜蓿在孕蕾之前到孕蕾初期扦插较好。一般成活率可高达85%,而且幼苗生长发育快。开花期以后成活率显著下降。苜蓿插条必须带有一个叶节,否则,在大田条件下没有成活率。一个枝条上,下部节成活率高,但有个别例外,还需要进行试验.上部节的幼苗,生长发育较快。扦插幼苗比种子幼苗生长发育快,扦插当年较早的时候,就能收到种子。扦插幼苗的成活,有几个关键性问题:保证充足的光照;扦插前期的饱和湿度;适时的锻炼.
Alfalfa greenhouse cuttings, foreign countries have been reported. In this paper, the grazing station of Gansu Agricultural University near field trials to cuttage.The experimental results show that: alfalfa before pregnancy bud to bud early pregnancy better. The general survival rate can be as high as 85%, and seedling growth and development. After flowering, the survival rate decreased significantly. Alfalfa cuttings must have a leaf knot, otherwise, there is no survival rate under field conditions. A branch, the lower section of high survival rate, with a few exceptions, but also need to test the upper section of the seedlings, grow faster. Cutting seedlings grow faster than seedling growth, cuttings earlier that year, you can receive seeds. The survival of cutting seedlings, there are several key issues: to ensure adequate lighting; pre-saturation of moisture; timely exercise.
