沿海防护林木麻黄优良品种采穗圃营建技术的研究

通过对福建沿海防护林木麻黄采穗圃的营建与生产技术的试验研究,确定了木麻黄采穗圃的母株定植密度以0.8 m×0.5 m较为适宜;以40 cm截干高度的母株所采的木麻黄穗条为最多;1年生母株的穗条水培的出根率达90%以上;第3年穗条的出根率仍在50%以上,木麻黄采穗圃作为无性快繁水培苗可持续使用3 a以上;共培育了速生抗病木麻黄2号(P10-33)、3号(粤501),抗风抗虫的惠1、C38、C44等抗逆无性系的出根苗600多万株。

Establishment of Cutting Orchard of Improved Variety for Coastal Protection Forest of Casuarina spp.

Establishment and production technology for the coastal protective forest of Casuarinn spp.in Fujian was studied.Results showed that the suitable relatively plants density of the maternal plant is 0.8 m×0.5 m.The scions of Casuarinn spp.cutted from the 40 cm truncation are the most.The hydroponics rooting of scions cutted from the 1-year-old maternal plant is up to 90%.The 3-year-old rooting was still up to 50%,so the hydroponics seedlings in the cutting orchard of Casuarinn spp.can be continue used more than 3 years.More than 6 million fast-growing and anti-disease Casuarinn spp.No.2(P10-33),No.3(Yue 501),Hui 1 with wind-resistance and pest-resistance,C 38,C44 saplings were cultivated together.
