不同修剪措施对平欧杂交榛苗木繁殖的影响

Effect of Different Pruning Measures on Seedling Breeding for Corylus heterophylla×Corylus avellana

试验以章古台地区沙地栽培的3个品(系)平欧杂交榛(Corylus heterophylla×C.avellana)为试材,研究了重剪、轻剪、自然生长3种修剪措施对平欧杂交榛植株繁殖苗木的数量、基径、高度的影响。结果表明:不同修剪处理都可以提高平欧杂交榛的苗木繁殖数量;重剪处理虽然可以显著提高植株的繁苗数量,但繁殖的苗木基径明显小于轻剪处理,繁殖的苗木高度也显著低于自然生长的植株;不同品(系)的平欧杂交榛植株繁育情况也有差异,82-11繁育数量明显高于84-226和84-254。

Taking three strains of Corylus heterophylla ）〈 Corylus avellana （82 11,84-226 ＆- 84-254） cultivated in Zhanggutai sandland as test materials, effect of three kinds of pruning treatments （heavy cut, light cut 〉 natural growth ） on number, basal diameter and height of breeding seedlings for Corylus heterophylla X Corylus avellana. Result shows that： different pruning treatments can improve breeding quantity of seedling of Corylus heterophylla X Corylus avellana;although heavy cut treatment can significantly increase number of reproducing seedlings of plant,basal diameter of breeding seedlings are significantly smaller than that with light-cut treatment; height of breeding seedlings is also significant lower than that of the naturally grown plants;reproducing condition of different strains for Corylus heterophylla X Corylus avellana are also different;breeding numbers of 82-11 are significantly higher than that of 84-226 ＆ 84-254.
