Description
Technical field
The present invention relates to improve the processing method of alder choiceness fringe bar output, particularly relate to～kind improve the processing method of Taiwan alder choiceness cutting orchard fringe bar output.
Background technology
Taiwan alder (Alnus formosana) is an arbor, reaches more than the 30m in the original producton location height of tree, and diameter of a cross-section of a tree trunk 1.3 meters above the ground 40cm, the bark taupe, the branch puce does not have hair, tool bar rib, sprig is dredged by pubescence, and bud tool handle is avette, two pieces of perulas of tool.Elliptic leaf shape is to square circle lanceolar, less ovum shape square circle, long 6cm～12cm, wide 2cm～5cm, the top is point or sharp point gradually, the circular or wide wedge shape of base portion, the irregular serration of edge tool, the two sides does not all closely have hair, the sparse hair worn in a bun or coil hair of tool between Xia Mian arteries and veins armpit sometimes, 6 pairs～7 pairs of lateral veins; Petiole is carefully thin, and long 1.2cm～2.2cm is close by the brown pubescence along groove.In October at florescence, 3 pieces～5 pieces of male inflorescences are also given birth to, and are about 8cm, and bract scale does not have hair, and 1 piece～6 pieces of infructescence are lined up total shape, ellipse, and long 1.5cm～2.5cm, total stalk is about 1.5cm, and the long 3mm～5mm of preface stalk is all more sturdy, the long 3mm～4mm of fruit bud.The nutlet obovate, long 2mm～3mm, the wing of tool ground paper matter, wing is wide to be 1/4～1/3 of fruit.
It is comparatively extensive that alder original producton location, Taiwan distributes, and to height above sea level 3000m natural distribution arranged all from low height above sea level, 21 ° 50 '～25 ° 15 of north latitude ' and, 120 °～122 ° of east longitudes.Alder original producton location, Taiwan weather warm and moist, the rainfall abundance, 10.6 ℃～22.5 ℃ of year sammings, extreme lowest temperature-7.6 ℃, soil is mountain region yellow earth, yellowish soil and brown earth, neutral slant acidity soil.The Taiwan alder often is born in small stream limit, river valley, wasteland, becomes pure forest sometimes, happiness light, and the wet and moisture-proof of happiness, barren-resistant, and the certain drought-resistant ability of tool.In the high altitude localities, Taiwan, the Taiwan alder is most important pioneer's reproducting tree species.
The eighties in last century, the Taiwan alder is carried out and is introduced a fine variety China mainland cultivation, show good, fast development along with the alder pulping and paper-making, market is increasing to the demand of Taiwan alder clone breeding nursery stock, but the technology that just improves production volume of choiceness clon spike strip of Taiwan alder there is no report at present both at home and abroad.
Applicant of the present invention has carried out the management exercise of alder (Alnus cremastogyne Burk) cutting orchard clone tree body, by to alder clone cutting orchard clone plant heading height, branch is pruned experimental studies such as intensity, think that the total bud number of spray and clone plant heading height and the branch pruning intensity etc. of alder clone plant are closely related, alder clone plant heading height is advisable with 90cm, and the clone branch should adopt light cutting back, so both can improve the total bud number of clone plant spray, enlarge tree crown again, strengthen tree vigo(u)r, guarantee the stable high yield of cutting orchard plugged ear, simultaneously, alder cutting orchard clone plant damage by disease and insect is studied, to the chrysomelid food leaf that waits of alder, trunk borer, adopt flolimat, insecticides such as Belmark are prevented and treated, to diseases such as sooty moulds, adopt mancozeb, bactericide such as carbendazim or thiophanate methyl is prevented and treated, and has received very good effect.
Applicant of the present invention has carried out the influence of alder (Alnus cremastogyne Burk) clone plant different disposal to the tender sprout number, adopting epicormic branch cuttage is to improve the grow seedlings effective way of planting percent of alder clone, set up alder clone cutting orchard, help improving clonal reproduction coefficient and planting percent, the variation of research alder clone plant tender sprout number, changing definite its spray plugged ear output by it is the variation of stachys-producing rate, in order to instruct the scientific management of alder clone cutting orchard, to improve the fringe bar output of clone plant.Alder clone characteristic and its tender sprout number are closely related, but clone plant planting density also has considerable influence to the tender sprout number.Individual plant tender sprout number changes with the variation of standing area, and cutting orchard clone plant planting density is preferably 1m * 2m.The test of alder clone plant heading height shows: to do the high best results of 90cm surely, it is one of effective measures that improve individual plant tender sprout number that appropriateness is pruned clone plant branch, different its differences that influence of intensity of pruning to individual plant tender sprout number, by clone plant branch is pruned, can increase branch quantity, thereby improve individual plant tender sprout number, branch is pruned intensity with light, middle cutting back best results.Though alder is a nitrogen fixing tree, but its young age grade section nitrogen fixing capacity relatively a little less than, alder is had relatively high expectations to soil nitrogen, nitrogen fertilizer application can significantly promote alder clone plant strain growth, increase branch length and branch quantity, reduce degree of lignification, improve individual plant tender sprout number, fertilizing amount is executed urea 0.2kg with every strain and is advisable.
Zhou Xiaoling (the science and technology committee deputy managing director of Hu'nan Prov. Academy of Forest-Sciences, researcher) etc. studies the main photosynthesis characteristics of alder (Alnus cremastogyne Burk), 4 years living young growths of Taiwan alder (Alnusformosana). and the result shows: the photosynthesis diurnal variation of (1) two kind of alder has two types of unimodal and bimodal curves, Sichuan alder photosynthesis diurnal variation June, September Net Photosynthetic Rate be the bimodal curve type, April and October, November, Net Photosynthetic Rate was the unimodal curve type; Taiwan alder Net Photosynthetic Rate diurnal variation is the bimodal curve type in April, June, October and November, and September, the Net Photosynthetic Rate diurnal variation was the unimodal curve type. the Net Photosynthetic Rate peak value with June in a year is the highest, reach 18.68 and 23.51 μ mol/m2.s respectively, October or November are minimum. and (2) two kinds of alder intensity of illumination diurnal variations become unimodal curve all the time, the just asynchronism(-nization) of peak value appearance, in April, June and September, intensity of illumination peak value 12:00～13:00 at noon occurs, illumination in October intensity with noon 12:00 the highest, November, 13:00 was the highest; In 1 year, intensity of illumination peak value June the highest (1800 μ mol/m2.s), the minimum in November, only 1260 μ mol/m2.s.
At present, the development of Taiwan alder afforestation is rapid, and supply falls short of demand for its clone nursery stock, and the production technology exploitation that improves production volume of choiceness clon spike strip of Taiwan alder is extremely urgent.Applicant of the present invention has carried out going deep into system research to the technology that improves production volume of choiceness clon spike strip of Taiwan alder, has found the Changing Pattern that it is special, has proposed to improve the technology of production volume of choiceness clon spike strip of Taiwan alder.
Summary of the invention
