| 摘 要： | 为了延长草方格沙障固阻流沙功效,在年降水量为70.95~133.25 mm的精河县境内的草方格沙障中开展罗布麻种植试验。结果表明:无灌溉条件下,罗布麻株丛平均萌发率为45%~88.75%;因无管护及抚育,至7月上旬,仅一处试验点有存活植株,平均保存率为58.65%,存活植株方格占比为95%。罗布麻对非生物逆境具有良好的适应性,为提高罗布麻保存率实现固沙目标,必须采取罗布麻生长维护措施。

| Abstract: | In order to prolong the sand-fixing function of the grass-grid sand-barrier,the cultivation experiment of Apocynum venetum was conducted in the grass-grid sand-barrier in Jinghe County with an annual precipitation of 70.95-133.25 mm.Under the condition of no irrigation,the average germination rate of A.venetum bushes is more than 45%,and the highest is 88.75%.Due to lack of management,protection and care,as of early July,only one test site have surviving plants,with the survival rate of 55%,and surviving plants grids accounting for 95%.A.venetum has optimal adaptability to abiotic stress,but in order to improve the survival rate of A.venetum to achieve the purpose of sand fixation,the growth&maintenance measures of A.venetum must be taken well. |
