A field preservation method for the vitality of ancient poplar cuttings

Abstract

The invention belongs to the technical field of asexual reproduction, and discloses a method for preserving the vitality of ancient poplar cuttings in the field, comprising: cutting the cuttings of ancient poplars with full lateral buds in the field; Bundled into bundles; bundled ancient poplar cuttings are wrapped in moist cotton gauze during daytime transportation, sprayed with water to moisturize from time to time according to needs, and placed in a cool place; transported the next day, bundled into bundled ancient poplar cuttings at night Soak the lower end of the cuttings morphology in the mixed solution, take out the cuttings during daytime transportation, spray the cotton gauze until water droplets can be wrung out, completely wrap the cuttings, spray water from time to time according to the need, and keep the cotton gauze moist all the time. Try to put it in a cool place; the cuttings are transported to the nursery for cutting in time. The invention has the advantages of simple operation, simple and convenient process, reduced cost, prolongs the preservation time of ancient poplar cuttings, greatly improves the survival rate of ancient poplars, and brings great convenience to the work of cutting seedlings of ancient poplars.

Description

technical field [0001] The invention belongs to the technical field of asexual reproduction, in particular to a method for preserving the vigor of ancient poplar cuttings in the field. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Poplar has the characteristics of wide distribution, strong adaptability, fast growth, easy reproduction and wide application, so it is regarded as an excellent afforestation tree species for papermaking, shelter forest and short-term rotation, and has made significant contributions to forestry production and regional ecological governance. The geographical and climate types in Southwest China are complex and diverse, and the genetic resources of Poplar are very rich. It is one of the natural distribution centers of poplar in my country. Due to the unique geographical and historical conditions, this area contains rich ancient poplar resources, which are distributed in natu...

AI Technical Summary

Problems solved by technology

[0009] (1) prior art, operation is complicated, and process is loaded down with trivial details, and cost is high;

[0010] (2) The vitality of ancient poplar cuttings is preserved for a short time, and they are easily polluted during long-distance transportation, which affects the rooting of cuttings and greatly reduces the survival rate of ancient poplars

[0011] (3) The existing technologies and methods are aimed at young and middle-aged poplars, and many ancient poplars have entered the advanced age, the tree vigor is very weak, the cuttings have low vigor, and some are more seriously damaged by diseases and insect pests, so conventional preservation The technology does not solve the problem that the vitality of ancient poplar cuttings is significantly reduced during the transportation process, resulting in a lower survival rate of cuttings and a higher incidence of disease during cutting seedlings

[0012] In the prior art, when multiple samples are collected, plus the time required for cutting cuttings collection, the time from cuttings leaving to cutting near the seedbed is as short as one or two days, and as long as about 7 days. However, using conventional methods, only It can be stored for 1-2 days. Therefore, how to prolong the time of vigor preservation after the cuttings are separated from the mother plant has become a key technology for cutting seedlings
