Embodiment 1

[0026] (1) Experimental location and objects

[0027] Location: Huaguo Mountain, Chongzhou City, Sichuan Province, has an inland subtropical humid monsoon climate, with an annual average temperature of 14.9-16.7°C, an annual frost-free period of 273-279 days, an annual average precipitation of 925.4 mm, and an annual average sunshine of 1239.1 hours.

[0028] Test materials: The test garden covers an area of ​​about 20 mu. The 5-year-old plum tree is cultivated in the open field.

[0029] (2) Implementation content

[0030] On February 10, 2007, on a sunny day, 60 premature senescent 5-year-old plum trees were randomly selected, which belonged to premature senescent trees with poor root neck growth or poor rootstock and ear compatibility. Among them, 20 were stronger trees and 20 were weaker trees. , 20 plants with no economic output for 2 consecutive years; 60 premature senescence trees are divided into treatment group and control group with 30 plants each, 10 trees with str...

Embodiment 2

[0040] In the spring of 2002, 5-year-old apricot trees in Xinghua Village, Qingbaijiang River, randomly selected 40 premature senescence trees, which belonged to premature senescence trees with poor root regeneration and few fibrous roots, 20 trees in each treatment and control.

[0041]Treatment: Throw away the soil at 15cm above and below the root neck, clean it, dip the mixed solution of 0.3% potassium permanganate solution and 70% thiophanate-methyl 1200 times solution with gauze, and wrap the area for 15 minutes; Cut the cortex twice with a saw or a single-sided blade about 2cm below the grafted part of the trunk. The width between the first and second circles is 15mm, and then use a knife and tweezers to gently pick off the bast part between the two circumcision circles; Cover the wound with a mixed matrix with a thickness of about 15 cm from top to bottom, left to right, and the mixed matrix is ​​composed of the following raw materials in volume percentage: 10% perlite, ...

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...
