Propagation method for rapid seedling formation of actinidia arguta

Abstract

The invention discloses a propagation method for rapid seedling formation of actinidia arguta. The propagation method comprises the following steps of 1, explant selection, specifically, in November every year, selecting a robust plant growing for 1-2 years, selecting a branch with the stem thickness of 0.5-0.8 cm and full axillary buds on the plant, and cutting the branch into cutting sections with the length of 15-20 cm, and enabling each section to be provided with 3-5 buds; 2, pretreatment, specifically, putting the cutting sections obtained in the step 1 into a K2SO4 solution with the concentration of 0.05-0.13 mg.L<-1>, and soaking for 30-40 minutes; and 3, induction culture, specifically, fishing out the cutting sections pretreated in the step 2, covering the cutting sections with wet cloth with the thickness of 3-5 mm, culturing in an environment with the temperature of 20-32 DEG C and the humidity of 60%-75%, and washing the cutting sections with water with the temperature of 25 DEG C once every morning and evening in the period to obtain rooting and sprouting cutting sections. The method is low in cost, efficient, rapid, simple and high in operability, and can be widely applied to rapid large-scale seedling propagation cultivation of the actinidia arguta.

Description

technical field

[0001] The invention relates to the technical field of kiwi fruit propagation, in particular to a method for rapidly growing seedlings of kiwi fruit. Background technique

[0002] Jujube kiwifruit, also known as Chinese soft jujube kiwifruit, soft jujube, rattan melon, dog jujube, golden fruit tree, kiwi pear, kiwi fruit, soft jujube, deep mountain wood Polygonum, vine pear, small foreign peach, etc., is a vine deciduous plant of the Actinidiaceae Actinidia . The fruit is edible, has high nutritional value, contains a lot of vitamin C, starch, pectin, etc., and can be processed into jam, juice, preserved fruit, canned food, wine making or used to make cakes, candies and other foods. It can also be used medicinally, and has the functions of strengthening, antipyretic, invigorating the stomach, and stopping bleeding; the root and root bark have certain therapeutic and inhibitory effects on digestive tract cancer; the oil content of the seeds is 35.62%, which i...
