摘要
通过采用"全光喷雾"设备,对新疆南疆3个地理种源的4种大沙枣插穗在不同扦插基质下以GGR 6号生根粉浸泡作为处理,以清水浸泡作为对照,进行硬枝扦插育苗试验。试验优选了提高大沙枣硬枝扦插苗生根率及成活率的方法。试验结果表明:用生根粉处理的插穗中喀什1号沙枣的平均成活率最低,仅为72%,最高的是和田1号和阿克苏1号,为91%,但均比用清水处理的生长率高;GGR 6号生根粉的最适质量分数为1.0×10-4,最佳基质为A基质(40%黄土+30%细河沙+10%炉灰+10%锯末+10%羊粪);采用GGR 6号生根粉浸泡处理4 h以上,可以有效地提高扦插的成活率。
Using equipment of full illumination spray, 4 kinds of sticks of Elaeagnus moorcrofiii among 3 geographical provenances in south Xinjiang were soaked with different matrix and amount of GGR No. 6 rooting powder for the control; hardwood cutting tests were conducted. The methods for improving rooting rate and survival rate of hardwood cuttings of Elaeagnus moorcrofiii were optimized. Result shows that：the average survival rate of Kashi No. 1 treated with rooting powder, which is the lowest,is only 72% ;the average survival rate of Hetian No. 1 and Aksu No. 1 ,which are the highest and higher than that by clearwater treatment,are 91% ;the optimum amount of GGR No. 6 rooting powder is 1.0 × 10 ^-4 ;the best matrix is the A matrix （40% Loess ＋ 30% fine sand ＋ 10% furnace ash ＋ 10% sawdust ＋ 10% sheep manure） ; GGR No. 6 rooting powder which are soaked more than 4 h can effectively increase the survival rate of cutting.
