Blueberry top-grafting treatment method for promoting germination and growth of scion

Abstract

The invention discloses a blueberry top-grafting treatment method for promoting germination and growth of a scion, comprising the following steps: rootstock treatment: coating the part below a grafting part of a blueberry rootstock by a sprouting inhibiting coating; treatment on the grafting part and a scion part: healing a grafted wound by a wound healing agent, soaking and spraying the scion bya germination promoting agent around germination; management after grafting: covering a base part by high-density polyethylene superfine fiber reflective cloth, timely removing the sprouting inhibiting coating and conducting conventional management. According to the invention, biological and physical methods are adopted to inhibit sprouting, so that occurrence of sprouting at a trunk and the baseduring a top grafting process of blueberry is effectively reduced, and nutrient consumption is reduced; and the germination promoting agent reduces the adverse effect of an inhibitor on the scion andpromotes germination of the scion and growth of new shoots, the coverage by the ground cloth reduces occurrence of ground sprouting, and therefore through combination of physical and chemical methods,a new variety of canopy of blueberry can be early formed after top grafting, manual input is reduced, production costs are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of high-level grafting of fruit trees, in particular to a treatment method for high-level grafting of blueberries that promotes the germination and growth of scions. Background technique [0002] Blueberry belongs to the shrub fruit tree of Rhododendronaceae. Because it is rich in anthocyanin and other antioxidant substances, it has been designated as an essential daily nutritional and health fruit by developed countries such as the United States. my country's blueberry industry is developing rapidly. However, due to the high requirements of foreign excellent blueberry varieties on cultivation conditions, it is difficult to adapt to my country's complex soil and climatic conditions. Production costs have been greatly increased, and some even suffered heavy losses due to insufficient conditions. After years of practice, Chinese producers have discovered that there are some varieties with strong stress resista...

Problems solved by technology

However, because blueberries belong to shrub plants, when shrub plants are replanted in high grafting in actual production, it is very easy to produce a large number of new branches (sprouts) of the original variety from the trunk and base, and these sprouts compete with the scion for nutrients and water. , affecting the germination and growth of scion buds, resulting in low germination rate and slow growth of scion buds, and finally it is difficult to form a crown

The patent discloses manual treatment measures for sprouting tillers, but the patent does not further disclose other measures for treating sprouting tillers. However, the existing manual removal of sprouting tillers requires long-term multiple operations, which is labor-intensive and time-consuming. big investment
