贵州喀斯特峰丛洼地引种欧李扦插繁殖初步研究
|
摘要
以3年生贵州引种欧李——"欧李4号"嫩枝为插穗,采用不同基质、不同植物生长调节剂及浓度进行处理,分析比较春插、夏插欧李生长差异,探索喀斯特峰丛洼地引种欧李最适扦插方案。结果表明:在喀斯特地区,欧李春夏两季扦插表现趋势类似,但夏季扦插比春季扦插的效果更好,且所用植物生长激素均能促进插条生根。实验5﹑实验6和实验8的方案均为春夏扦插实验的最优方案,其中实验8的效果最好,即河沙+珍珠岩3:1为基质,并以500mg/L的ABT1生根粉溶液处理插穗1min效果最理想。
In order to find the optimal cottage programs of introduced Cerasus humilis in Karst peakcluster depression areas,the twigs of 3years old Cerasus humilis 4,an introduction of Cerasus humilis in Guizhou,were used as the cuttings and had been treated with different matrix,plant growth regulator and concentration to compare the difference between spring cuttings and summer cuttings.The result showed that the cutting performance of the two seasons is similar in Karst peak-cluster depression area,but summer cuttings are better.Four kinds of plant growth regulator can obviously promote the rooting of cuttings in summer.Experiment 5,Experiment 6and Experiment 8are optimal schemes for spring and summer cutting experiments,in which experiment 8has the best effect.Therefore,the best solution is the treat of matrix of river sand + perlite(3:1)and 1 minute of 500 mg/L of ABT1 rooting powder.
