Plum retraction and rejuvenation nursery stock cultivation method

Abstract

The invention discloses a plum retraction and rejuvenation nursery stock cultivation method, which comprises the following steps of: shearing aging and vertical branches and cultivating regenerated buds, pruning and controlling shapes; cultivating the regenerated buds: shearing the aging and vertical branches and spraying and washing the wounds with alcohol for 2-3 times; spraying with sterile water for 3-5 times; spreading bud regeneration promotion gel on the wound surfaces and peripheries, covering the wound surfaces completely, wrapping binding bags from the lower part to upper part of thewound surfaces for 2-3 days by using firm and elastic plastic film strips with a width of 1-2 centimeters, pruning and controlling the shapes when the regenerated buds grow to be 35-40 centimeters long. The bud regeneration promotion gel comprises the following raw materials: chitosan, polyhexamethylene biguanide, calcium chloride, salicylic acid, indolebutyric acid, modified starch, polyhexamethylene biguanide, calcium chloride, indolebutyric acid and salicylic acid which are prepared into a mixed solution; modified starch and chitosan are mixed to obtain the gel, the gel is mixed with the solution and stirred, and sterilizing is carried out to obtain the final product. The method effectively stimulates the extraction of the retracted and regenerated buds of the plum, and simultaneouslyadjusts the stress resistance of retracted nursery stock and promotes the rejuvenation and yield increasing of the plum.

Description

technical field [0001] The invention belongs to the technical field of plum planting, and in particular relates to a method for cultivating plum shrinkage and rejuvenation seedlings. Background technique [0002] Plum is one of the fruits with a long history of cultivation in my country. It contains sugar, protein, carbohydrate, carotene, glycine, threonine, proline, alanine and calcium, iron, potassium, sodium, magnesium, phosphorus and other ingredients. It can improve appetite and promote digestion, so it is very popular among people. Retraction and rejuvenation in the plum production process is the key to increasing yield, but excessive reproduction of regenerated buds during the retraction and rejuvenation period can easily cause malnutrition in regenerated buds, increase the risk of disease, and ultimately affect fruit production. [0003] Chitosan and its derivatives have many advantages such as non-toxic, biodegradable, biocompatible, antibacterial, adsorption, and g...

Retraction and rejuvenation is the key to increase yield during the plum production process, but excessive reproduction of regenerated buds during the rejuvenation period can easily cause malnutrition of regenerated buds, increase the risk of disease, and ultimately affect fruit production

[0003] Chitosan and its derivatives have many advantages such as non-toxic, biodegradable, biocompatible, antibacterial, adsorption, and good film-forming properties. They are used in medical antibacterial dressings in combination with polyhexamethylene biguanide. There are public reports that chitosan, polyhexamethylene biguanide, calcium chloride, salicylic acid, indole butyric acid, and modified starch are combined to make regeneration-promoting bud gel for the cultivation of fruit tree recovery and rejuvenation seedlings
