Root-replacement method for prolonging economic life of plum and apricot plants

Abstract

The invention discloses a root-replacement method for prolonging the economic life of plum and apricot plants, and belongs to the technical field of plant cultivation. The root-replacement method comprises the following steps: (1) washing root collars having the length of 10 cm-15 cm of plants, dipping the gauze in a mixed solution of potassium permanganate and thiophanate-methyl, and covering theroot collar with the gauze; (2) cutting the cortex in trunks of the plants two rounds, and removing phloem between the two cutting rings; (3) using a mixed matrix to cover around the two cutting rings, and filling and leveling the root collars with soil; (4) watering the soil with a mixed solution of rooting powder and a seaweed extract, and using a blank film to cover tree discs having the diameter of 1 meter; and (5) spraying the plants with water every 10-15 days within 2 months after germination of leaf buds. The root-replacement method effectively solves the phenomenon of premature agingof trees caused by three main factors: poor growth of root collars of trees, poor affinity of rootstocks and scions and poor growth of roots, can achieve high yield and stable yield, can improve thefruit quality and effectively prolong the economic life of fruit trees, and is simple, efficient and fast.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a root replacement method for prolonging the economic life of plum and apricot plants. Background technique [0002] Plum and apricot are drupe fruit trees. Most of them have strong adaptability and are not particularly strict on soil and climate. Generally, they have thick branches, well-developed root system, early fruit and high yield. They can be put into production 2-3 years after planting, and 4-4 It can enter the high-yield period in 5 years, and the production cycle can be as long as more than 20 years. But at present, many plum and apricot orchards are due to low construction standards, extensive management, lack of nutrition and blind fruit bearing, especially some fruit trees in the southern red-yellow soil area have difficulty in sprouting new shoots, slow growth of branches and leaves, and yellowing However, in 10-12 years, most fruit trees wil...

Problems solved by technology

[0006] In order to solve the above-mentioned defects in the prior art, the present invention proposes a root replacement method for prolonging the lifespan of drupe fruit trees. Premature aging of trees caused by main factors, improving the plant drainage system can not only achieve high and stable yields, but also help improve fruit quality and effectively prolong the economic life of fruit trees
