Embodiment 1

[0044] A method for biological control of plant diseases and insect pests in cold temperate regions:

[0045] (1) At the beginning of March, paint the trunk white, trim the tree body, remove litter and leaves, and take it out of the orchard to fill or burn it.

[0046] (2) From late March to early April, during the germination period of the tree body, dig a 30cm wide and 15cm deep annular ditch at a distance of 30cm from the trunk under the canopy, dilute the biological bacterial agent 1000 times to obtain the biological bacterial agent liquid, and then Pour the liquid medicine into the annular ditch evenly, the dosage of the liquid medicine is 15kg / plant, and cover it with soil after the liquid medicine seeps down.

[0047] The preparation method of the biological bacterial agent: the mass ratio of the bacillus thuringiensis, the stevia rebaudiana extract, and the salicornia extract is mixed uniformly to obtain the biological bacterial agent.

[0048] The preparation method of...

Abstract

The invention discloses a biological control method for garden plant diseases and insect pests in a cold temperate zone, and belongs to the technical field of agriculture. The pest and disease damage biological control method comprises the following steps: irrigating a biological agent in a tree body germination period; pest control: pest control is carried out by combining pest physical control and pest biological control; disease prevention and control: performing disease prevention and control by using a disease biological prevention and control means; wherein the biological agent is prepared from the following components: bacillus thuringiensis, a stevia rebaudiana extracting solution and a salicornia europaea extract. According to the method, the biological agent is adopted to irrigate roots, and measures such as pest physical control, pest biological control and disease biological control are combined, so that the morbidity of plant diseases and insect pests is effectively reduced, potential threats of the diseases and insect pests to the garden industry are eliminated, and sustainable development of the garden industry is ensured.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a biological control method for garden plant diseases and insect pests in cold temperate regions. Background technique [0002] The cold temperate zone refers to the area where the accumulated temperature is less than 1600°C. The cold temperate coniferous forest is composed of cold-resistant evergreen or deciduous coniferous species, and is a forest type with a wide distribution area and rich resources. It is mainly composed of spruce, fir, larch and some hardy pines and junipers. This kind of coniferous forest can adapt to cold, humid or dry climate conditions. The cold temperate coniferous forest can generally be divided into two categories: one is the cold temperate deciduous coniferous forest, and the other is the cold temperate evergreen coniferous forest. The coniferous forest has the functions of forest ecological services, diverse forest species, and rich forest p...
