Abstract
The invention discloses a rapid salix-chaenomeloides-twig cutting-propagation technology, relates to the field of forest improved-variety breeding and realizes the purpose of rapidly propagating salix-chaenomeloides seedlings. The rapid salix-chaenomeloides-twig cutting-propagation technology has the advantages that 1) the excellent characteristics of salix-chaenomeloides female parents can be kept; 2) the survival rate reaches more than 95 percent; 3) the purpose of propagating salix chaenomeloides in batches is realized.
Description
Technical field
The present invention relates to high quality tree species and breed field, be i.e. a kind of gland willow spray rapid cuttage propagation technique.
Background technology
Gland willow (formal name used at school: Salix chaenomeloides Kimura) dungarunga.Branch crineous or bronzing, glossy.Capsule ovum shape ellipse, long 3-7 millimeter.April at florescence, really May phase.Mainly be distributed in North of Yangtze River area.Be born in by 1000 meters of following (only tens meters of Liaoning height above sea level) gully water of height above sea level more.Happiness light, not resistance to the moon, more cold-resistant.Like moist fertile soil.Rudiment power is strong, resistance to pruning.Be suitable for doing around lake, pond, the identical woods green tree species of shelter forest of two sides, river.
Due to comparatively difficulty of gland willow seedling-wood breeding, the ripe cuttage technique of being also correlated with at present, Sterile culture method is difficult to realize in batches breeds, and the gland willow of Sterile culture is uneven of poor quality, how to solve its propagation technique, is the key that gland willow is applied.
Summary of the invention
The object of the present invention is to provide a kind of gland willow spray rapid cuttage propagation technique.
In order to complete object of the present invention, a kind of gland willow spray rapid cuttage propagation technique the present invention relates to is specific as follows:
(1) nursery is selected: should select physical features smooth open, soil layer is deep, the plateau tableland of fertile soil, flood land, and tool irrigation conditions.
(2) method of soil preparation: after thawing for northern area soil (the general 2 annual the end of month of south), carry out immediately whole ground, in conjunction with whole ground, every 667m
2execute farmyard manure 800～1500kg, apply appropriate superphosphate, composite fertilizer, the dregs of fat etc. simultaneously, and fertilizer is evenly sprinkled into earth's surface ploughs deeply, then make bed.Bed surface specification is wide 80cm, high 15～25cm, bed spacing 20～35cm, in bed a little more than edge of bed, cross section arch.Last whole fine earth earth, covering film, in order to cuttage.
(3) plant bar collection: generally with 1～2 year raw branch as cutting, preferably select annual stump bar, or annual germinating bar, make immediately cuttings after adopting bar.Cuttings specification is: fringe footpath 1～2cm, long 15～20cm.Planting bar should be the gland willow of robust growth.Adopt bar (north is generally in the time that soil thaws) in annual March.
(4) cuttings is made: under cuttings, tangent plane is 45 ° of angles with kind bar, and upper edge is vertical with kind bar, 1～1.7cm place lower cut above eye.Tangent plane requires smooth.
(5) tying up of cuttings: the cuttings of making, by position thickness grading, flat mouth, angle are forbidden to put upside down, and every 100 are bundled into a bundle.
(6) cuttings processing: before cuttage, the cuttings of having tied is put into clear water and soak 2～4 days.
(7) cuttage technique: generally carry out in spring (early or mid April).Each seedbed is along bed cuttage two row, by the equidistant fixed point of gage.Adopt the cutting of straight cutting method, when loosing soil, cuttings is directly inserted to seedbed, cuttings is with getting with inserting.Cutting density should be determined according to the object of cultivating nursery stock, and general line-spacing 40～45cm, spacing in the rows 25～30cm, with every 667m
2cuttage 4500～6000 strains are advisable.Cuttage angle, i.e. cuttings and ground inclination 30～45 degree, by cuttings to center, seedbed oblique cutting.The cuttage degree of depth should expose 2～3cm with cuttings top is advisable, and the plastics of cutting hole is pushed down with fine earth, in case burn rudiment.
(8) transplant: cuttage moves into land for growing field crops by cuttage seeding in 20～100 days, and water permeablely for it, shade 2～3 days, transplanting density is 5000～10000 strains/hm
2, Routine Management thereafter.
The present invention adopts a kind of gland willow spray rapid cuttage propagation technique, has realized the object of Fast-propagation gland willow seedling, and its advantage is: the good characteristic that 1. can keep gland willow female parent; 2. survival rate has reached more than 95%; 3. realized the object of breeding gland willow in batches.
Embodiment
Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Case study on implementation
(1) nursery is selected: within 2013, select forest farm, Beijing physical features smooth open, soil layer is deep, the plot of fertile soil is as nursery, and is furnished with irrigating facility.
(2) method of soil preparation: mid-March, soil carried out whole ground immediately after thawing, in conjunction with soil effort, every 667m
2execute farmyard manure 1200kg, apply appropriate superphosphate, composite fertilizer, the dregs of fat etc. simultaneously, and fertilizer is evenly sprinkled into earth's surface ploughs deeply, then make bed.Bed surface specification is wide 80cm, high 18cm, bed spacing 25cm, in bed higher than edge of bed 3cm, cross section arch.Last whole fine earth earth, covering film.
(3) plant bar collection: adopt 2 years raw branches as cutting.Cuttings specification is: fringe footpath 2cm, long 18cm.Plant bar from somewhere, middle reaches, the Changjiang river.Adopt bar at late March.
(4) cuttings is made: under cuttings, tangent plane is 45 ° of angles with kind bar, and upper edge is vertical with kind bar, 15cm place lower cut above eye.
(5) cuttings processing: before cuttage, the cuttings of having tied is put into clear water and soak 3 days.
