近年来,我们根据油橄榄高床扦插育苗,存在着保温保湿较差,给育苗管理带来一定困难的问题,试验用低床扦插,取得了良好效果。自1975年起,共扦插43,261支插穗,成活率达91.6%,最高达94.8%,与普通高床扦插相比,提高成活率达8%,节约管理用工70%。所谓低床,实际上是把整个高床降到地面以下,使扦插床内的插壤面低于地面10厘米,床面仍用塑料薄膜盖住(见图示)。这样的插床排水性虽然不如高床好,但是插壤的温湿度稳定,即是在夏季插壤的温度变幅也只有23— In recent years, according to Olive high cuttage cutting seedlings, there is a poor insulation moisturizing, nursery management to bring some difficult problems, the test with low bed cutting, and achieved good results. Since 1975, a total of 43,261 cuttings have been cut, with a survival rate of 91.6% and a maximum of 94.8%. Compared with ordinary high-cuttings, the survival rate is increased by 8% and the management and labor-saving by 70%. The so-called low bed, in fact, is to lower the entire high bed below the ground so that the inserted bed in the cutting bed is 10 cm below the ground and the bed is covered with a plastic film (see illustration). Such a drainage bed, although not as good as high-bed drainage, but the temperature and humidity in the interception of the soil stability, that is, in summer plunging temperature changes only 23-
