Embodiment 1

[0029] A method for cultivating cherry rootstock seedlings, the steps are as follows:

[0030] (1), collection and processing of cuttings

[0031] (1) Collection of cuttings: In June of each year, cut the 10cm-long cuttings of the healthy cherry rootstock 'Gisela' that year, cut the bottom of the branches obliquely at 45°, and cut off the 2cm higher lignified part of the base. Keep the top 3 leaves;

[0032] (2) Cutting treatment: first soak the cuttings with 0.5% potassium permanganate solution by mass percentage for 1 hour, then soak the base of the cuttings with NaHS solution for 3 hours, then soak the base of the cuttings with ABT1 rooting powder solution for 2 hours;

[0033] The concentration of the ABT1 rooting powder solution is 400mg / kg.

[0034] (3) Treatment of the low-temperature groove of the top bud: the groove is arranged in a greenhouse without a film, the bottom of the groove is 70cm lower than the ground, and the surrounding is lined with a leak-proof film,...

Embodiment 2

[0046] A method for cultivating cherry rootstock seedlings, the steps are as follows:

[0047] (1), collection and processing of cuttings

[0048] (1) Collection of cuttings: In June of each year, cut the newborn 12cm long cuttings of the healthy cherry rootstock 'Court' in that year, cut the bottom of the branch at 45°, cut off the 3cm higher lignified part of the base, and keep top 2 leaves;

[0049] (2) Cutting treatment: first soak the cuttings with 0.5% potassium permanganate solution by mass percentage for 1h, then soak the base of the cuttings for 5h with NaHS solution, then soak the base of the cuttings for 3h with the ABT1 rooting powder solution, the concentration of the ABT1 rooting powder solution 500mg / kg;

[0050] (3) Treatment of the low-temperature groove of the top bud: the groove is arranged in a greenhouse without a film, the bottom of the groove is 70cm lower than the ground, and the surrounding is lined with a leak-proof film, and a treatment room is bui...

Abstract

The invention relates to a seedling breeding method of cherry rootstocks, belonging to the field of plant cultivation. The method comprises the steps of collecting and treating cutting slips, preparing a cutting bed, carrying out cuttage and managing after cuttage; the cuttage of the cutting slips of the cherry rootstocks is carried out in a greenhouse, and the cherry rootstocks can be obtained by controlling the illumination, the temperature, the relative humidity and the water content of a cutting medium. After the seedling breeding method of the cherry rootstocks is adopted, the rooting time of cutting seedlings of the cherry rootstocks is shortened to about two weeks, the survival rate reaches 98%, and the late growth potential is strong.

Description

technical field [0001] The invention relates to a seedling breeding method, in particular to a cherry rootstock seedling raising method. Background technique [0002] The big cherry is the earliest fruit tree species of deciduous fruit trees in northern China after the Chinese cherry. Therefore, it has long been known as "the first branch of spring fruit". It plays a special role in regulating the off-season of fresh fruit, balancing annual supply and meeting the needs of people's lives. Cherry fruit is rich in nutrients and has certain nutritional value for the human body. According to traditional Chinese medicine, cherry pick has the functions of regulating the middle and replenishing qi and dispelling rheumatism. Large cherry requires less management labor, low production cost, and high economic benefits. It is suitable for cultivation in Liaoning, Shandong, Shaanxi, Henan, Hebei, Guizhou and other places. [0003] The propagation method of large cherries is mainly gr...
