Green control method for tobacco planting plant diseases and insect pests

Abstract

The invention belongs to the technical field of agriculture and forestry pest control, and particularly relates to a green control method. Deep ploughing, ridge drying, non-toxic seedling growing, pesticide transplanting and transplanting period micro-ecological control rhizosphere are performed, aphidiidae are released in the land period, an insect food trap and an insect sex trap are placed, pesticide is sprayed, pointed methods are adopted for different stages of plant diseases and insect pests in the tobacco planting process for strict control, plant diseases and insect pests are effectively controlled, plant extractives and biological medicaments are adopted for replacing chemical pesticide, on the condition that no contamination is caused to the environment, plant diseases and insectpests are strictly controlled in the tobacco planting process, and the tobacco quality is remarkably improved.

Description

technical field

[0001] The invention belongs to the technical field of prevention and control of agricultural and forestry pests, and specifically relates to a method of deep plowing and sun-drying, non-toxic seedling cultivation, transplanting with medicines, micro-ecological regulation of the rhizosphere during the transplanting period, releasing aphids in the field period, and placing insects to eat and trap Devices and insect traps, spraying chemicals, to achieve the prevention and control of diseases and insect pests in the process of tobacco planting. Background technique

[0002] my country is the largest tobacco producer in the world today, and tobacco is an important economic crop in my country. There are many kinds of tobacco pests and diseases, which are very harmful to tobacco production. According to the national survey of tobacco infectious diseases and the national survey of tobacco insects, there are 68 kinds of tobacco infectious diseases in my country, and ...

Examples

Embodiment 1

[0028] (1) Deep plow and sun-dry the ridge twice in winter, with a plowing depth of 35cm, and expose to the sun for 7 days each time. Do not rotate with vegetable crops such as Solanaceae, Cruciferae, and Cucurbitaceae. Clean up diseased residues in time and keep the tobacco field clean. Add bio-organic fertilizer 50kg / mu;

[0029] (2) Before raising seedlings, use a 1000-fold diluent by volume to sterilize all seedling raising facilities with a 20% octoprodil water agent; set up 60-mesh insect-proof nets throughout the seedling raising shed; before seedbed operation, 1 day in advance Spraying 50kg mass ratio per mu is: after the Sophora flavescens extract of 1:5:2, Folium Artemisiae Argyi extract, Coptidis Rhizoma extract mixes the diluent diluted 100 times with water by volume ratio; Keep antiviral agents on the incision at all times;

[0030] (3) Before transplanting, use quicklime to adjust soil pH; use TMV rapid detection test strips to detect, and control the poisonous ...
