Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0020] Such as figure 1 As shown, in this embodiment example 1, the kiwi fruit with well-developed root system and strong growth is selected as the mother plant to obtain cutting shoots;

[0021] Putting the base of the cutting twigs into the growth regulator for soaking, and inserting the soaked cuttings into the cultivation dish with twig cuttings;

[0022] The survival rate of cuttings treated with activation was significantly higher, but most of the bases of cuttings only grew calluses but not roots, so the survival rate was significantly lower than that of hormone treatment. Among the single phytohormones, the effect of the lowest concentration of NAA (0.25g / L)...

Abstract

The invention discloses a rapid propagation and culture method of excellent kiwi fruit rootstock. The method comprises the following steps: rapidly propagating and culturing excellent rootstock, namely selecting actinidia kolomikta with a developed root system and robust growth as a stock plant to obtain cuttage twigs, and soaking the base parts of the obtained cuttage twigs in a growth regulator; and inserting the soaked twigs into a cultivation vessel in a cuttage mode; and culturing a to-be-disinfected culture medium prepared from vermiculite, coco coir, peat soil and garden soil are prepared in a mass ratio of 1: 2: 5: 3, and culturing the cuttage twigs with the culture soil which is the culture medium disinfected by formalin. According to the method, the actinidia kolomikta twigs are subjected to cutting culture, so that a large number of actinidia kolomikta cutting seedlings are rapidly obtained, the cutting seedlings serving as stocks can well achieve the characteristics of developed root system, drought resistance, water-logging resistance, cold resistance and the like of the actinidia kolomikta, and the quality of the actinidia kolomikta fruits can be improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation engineering, and in particular relates to a rapid propagation and cultivation method of excellent kiwifruit stock. Background technique [0002] Actinidia is a perennial deciduous fruit tree with climbing properties. Kiwi fruit is rich in nutrients. Its fruit is rich in dietary fiber, vitamins, proteins and minerals, among which vitamin C is extremely rich, known as the "king of fruits"; its roots, stems, leaves, etc. also contain a variety of biological The active substance has the effects of clearing away heat and promoting dampness, protecting the liver, reducing enzymes, and antitumor. Now, China's kiwifruit planting area and output both rank first in the world, and it is in a period of rapid development. [0003] Grafting propagation is the main propagation method of kiwifruit varieties. The difficulty of grafting and survival and the suitable stock and ear combination are the mai...
