Embodiment 1

[0025] A method for improving the survival rate of hardwood cuttings of quinces, the method comprising the steps of:

[0026] S1. Making cuttings: before and after the Qingming Festival, when the winter buds begin to expand, select the robust lignified quince branches grown last year, and cut them into section-shaped cuttings with branch scissors. Each cutting is 12-13cm long. Two pairs of healthy buds are reserved for cuttings, and the ports are flat and oblique; the whole cuttings are soaked in 0.5% potassium permanganate aqueous solution for 0.5h, and then soaked with 600-700ppm IBA auxin and 50mg / L vitamin B1 solution Base 1h; before selecting quince branches, fertilize the mother tree once at the beginning of August of that year, and remove miscellaneous and weak branches;

[0027] S2. Preparation of culture substrate: Carbonized rice husk, waste fungus sticks, and peat soil are used as the main ingredients of the substrate configuration. The ratio is reasonably controlle...

Embodiment 2

[0039]A method for improving the survival rate of hardwood cuttings of quinces, the method comprising the steps of:

[0040] S1. Making cuttings: before and after the Qingming Festival, when the winter buds begin to expand, select the robust lignified quince branches grown last year, and cut them into section-shaped cuttings with branch scissors. Each cutting is 14-15cm long. 3 pairs of healthy buds are reserved for cuttings, and the ports are flat and oblique; the whole cutting is soaked in 1% potassium permanganate aqueous solution for 1 hour, and then the base of the cutting is soaked in 700ppm IBA auxin and 75mg / L vitamin B1 solution for 1.5 hours ; Before selecting quince branches, fertilize the mother tree once at the beginning of August of that year, and remove miscellaneous and weak branches;

Abstract

The invention discloses a method for improving the hard branch cutting survival rate of cydonia oblonga. The method comprises the steps of preparing cuttings, preparing a culture medium, treating theculture medium, treating the cuttings, managing cutting seedlings and the like, wherein when the cuttings are prepared, robust lignified cydonia oblonga branches growing in the last year are selectedbefore and after the Qingming festival and when winter buds begin to expand, after the cuttings are cut into segment-shaped cuttings by using a branch shear, the length of each segment of cutting is 12-15 cm, and 2-3 pairs of healthy buds are reserved for each segment of cutting. The method has the advantages that the cuttings are selected when the temperature is proper before and after the Qingming festival, and growth regulating substances during cutting are treated, so that the moisture content of the cuttings is increased, the conversion of sugar and nitrogen compounds is promoted, the elimination of rooting inhibiting substances in the cuttings is facilitated, the respiration intensity is obviously improved, the formation of calluses and the differentiation of adventitious root primordia are promoted, and the rooting survival of the cuttings is further promoted; and during seedling management after cuttage, an arched shed and a sunshade net are arranged more reasonably, so that the survival rate of the cuttings is further increased.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a method for improving the survival rate of hardwood cuttings of quinces. Background technique [0002] Quince is a small deciduous tree. Young branches tomentose. The leaves are ovate or oblong, dark green on the surface, and densely tomentose on the back. Flowers solitary on branch tops, white or pink. Fruit pear-shaped, yellow, fragrant. The flowering period is April-May. Likes light and can tolerate half shade. Strong adaptability and cold resistance. The soil requirements are not strict, and it can be cultivated in generally well-drained land. It can be propagated by sowing, cuttings or layering. [0003] Grafting is the use of part of the plant's vegetative organs to graft onto other plants. The branches used for grafting are called scions, the buds used are called grafts, the grafted plants are called rootstocks, and the seedlings after grafti...
