Problems solved by technology

[0004] In the 1980s, Taiwan alder was introduced to mainland China for cultivation, and performed well. With the rapid development of alder pulp and paper, the market demand for Taiwan alder clone seedlings is increasing, but the increase in Taiwan alder There is no report on the cutting production technology of excellent clones of wood at home and abroad

Abstract

The invention discloses a process method which can improve Taiwan alder favorable clon grain strip output, which comprises the procedures that firstly, the clon planting density is 5000-10000 trunks / hm 2, secondly, the height of the trunk is regulated to be 30-100cm, thirdly, the lateral branch pruning intensity is that 25-35% of the length of the branch is pruned, fourthly, opsonizing soil, wherein, the pH value is 6-7, when the pH value is lower than 6, lime is used to opsonize, and the fertilizer amount of a single plant is 500-1000g, fifthly, weeds and arborets are controlled by adopting manual removing or chopping miscellaneous shrubs, and the height is controlled below 20cm. The invention can not only improve the Taiwan alder favorable clon grain strip output, but also improve the rooting rate of grain strip cuttage, and provides technique safeguard for scale breeding of Taiwan alder favorable clon seedlings for promoting development of Taiwan alder industrialization.

Description

technical field [0001] The present invention relates to the treatment method that improves the scion production of fine clone of alder alder, particularly relates to ~ one kind of processing method that improves the scion yield of the good clone of alder alder in Taiwan. Background technique [0002] Taiwan alder (Alnus formosana) is an arbor, with a height of more than 30m in the original place and a diameter at breast height of 40cm. Shaped, with two bud scales. Leaves elliptic to oblong-lanceolate, less ovate oblong, 6cm-12cm long, 2cm-5cm wide, apex acuminate or sharp, base round or broadly cuneate, margins with irregular fine serrations, Both surfaces are nearly glabrous, sometimes with sparse hairs in the axils of the lower veins, 6 to 7 pairs of lateral veins; petiole is thin, 1.2cm to 2.2cm long, densely covered with brown pubescence along the groove. Flowering in October, 3-5 male inflorescences grow side by side, about 8cm long, bract scales glabrous, 1-6 inflore...
