Problems solved by technology

[0003] However, the large-scale application of biological control is still relatively difficult, the plant cultivation environment is complicated, the climate diversity makes colonization of bacterial strains difficult, and the suitable production range of general bacterial strains is limited. These are the reasons why many biological control agents are difficult to be widely used
[0004] The prior art biological control has the following defects: after the active bacterial strain of the biological control agent enters the soil, the adaptability is poor, it will be inactivated quickly, and it is difficult to colonize; unbearable

Embodiment 1

[0040] (1) The experimental field was selected from the pomegranate orchard abandoned due to pomegranate wilt infection in Xin'an Town, Mengzi.

[0041] (2) After leveling the land, divide the land into blocks, each with a small area of ​​15m 2 , divided into 4 groups, the first group is the control group, without adding any biocontrol bacteria and planting Asteraceae weeds; the second group is added with biocontrol agent A, and the third group is added with biocontrol agent A and planted silver colloid chrysanthemum; the 4th group added biocontrol agent A and planted Artemisia annua, and each treatment set up three parallel groups; weed guayule and Artemisia annua, sowed 400 grains per square meter; the concentration of biocontrol agent was 55g / L.

[0042] (3) After the weed seeds emerge, thin the seedlings, and the row spacing of the weeds remains between 5cm;

[0043] (4) plant pomegranate saplings by the specification of 0.5m * 1m, and biocontrol fungicide A is poured a...

Abstract

The invention discloses a method for preventing soil-borne diseases of pomegranate. The method comprises the following steps: (1) spreading compositae weed seeds in a field to be treated, and spreading 400 to 500 granules of the compositae weed seeds per square meter; (2) after the weed seeds sprout, carrying out thinning; (3) planting pomegranate trees in the field; (4) irrigating antibiological inoculants surrounding the pomegranate tree according to 40L to 60L per Mu; (5) controlling the weed height at 5cm to 15cm; (6) after the antibiological inoculants are irrigated to the pomegranate tree for 2 to 4 months, carrying out the antibiological inoculants irrigation for the pomegranate tree again according to the same dosage; (7) according to the growth height situation of the weeds, performing the weed control once a month to every three months, so as to ensure the weed height to be at 5cm to 15cm. Under the natural state, the compositae weeds and the antibiological inoculants are processed collectively, so that a purpose of controlling the soil-borne diseases of the tree can be achieved.

Description

technical field [0001] The invention relates to the technical field of tree disease prevention and control, in particular to a method for preventing and treating soil-borne diseases of trees. Background technique [0002] Tree soil-borne diseases refer to the diseases caused by pathogens such as fungi, bacteria, nematodes and viruses living in the soil with the diseased residues and invading trees from the roots of trees when the conditions are suitable. It is a serious plant disease. Soil-borne diseases generally harm the roots and stems of plants, causing seedling root rot, withering or rotting damping, etc., causing huge economic damage to farmers. Soil-borne diseases of trees are more common in pomegranate. Pomegranate is a high-grade fruit and one of the important export fruits in my country. Pomegranate wilt is a soil-borne disease that affects the production of pomegranate most seriously. Studies have shown that the injured root is caused by the invasion of pathogens....
