CN101720605A - Pest prevention and control method for green vegetables - Google Patents

Abstract

The invention provides a pest prevention and control method for green vegetables, comprising the steps of treating seeds, disinfecting soil, sterilizing and deinsectizing in high temperature air-tight greenhouse and the like. By adopting the method, pests can be effectively killed without any chemical components, and the high temperature air-tight greenhouse enables fertilizer to ferment and become thoroughly decomposed adequately, thereby a great number of pest sources are killed.

Description

The diseases and pests controlling method of pollution-free vegetable

Technical field

The present invention relates to horticulture technique, particularly the diseases and pests controlling method of a kind of pollution-free vegetable.

Background technology

Pollution-free vegetable is meant the vegetables that polluted by harmful substance, that is to say that not containing some regulation in the commodity vegetables is forbidden the noxious material that contains, then will be controlled within the standard of permission some inevitable harmful substance.Therefore greengrocery provides the main source of people's dietary fiber, vitamin and mineral element, estimates their nutrition height around the quality characteristic of the content of this three constituents and various vegetables.This shows that pollution-free vegetable is not only and realizes the most basic material resources of Green Foodstuff Project, but also be one of important component part of agricultural sustainable development and environment for human survival assurance.

Summary of the invention

The invention provides the diseases and pests controlling method of a kind of pollution-free vegetable.

Technical scheme of the present invention is made up of following steps:

A, seed treatment

After before cultivation, earlier vegetable seeds being shone 2～3 days, use 40-55 ℃ of water seed soaking 10～20 minutes again; Clean with clear water after 10～20 minutes with the seed soaking of 10% tertiary sodium phosphate then;

B, soil disinfection

To spray bed soil behind 40～80 times of the formalin dilute with waters, every square metre of soil formalin 50ml, with film covering 2～3 days, airing was 7～8 days more then;

C, high temperature sterilization deinsectization

After the first crop crop harvesting is intact, do not remove stubble earlier, the canopy chamber is all airtight, vexed round the clock canopy 7～10 days, the canopy indoor temperature is controlled at 60～80 ℃, removes stubble in the canopy afterwards again; Before the fertilising fertilizer water-sprinkling is mixed wetly, piled up and to cover plastic film completely, 60～80 ℃ of temperature maintenances.

The present invention need not any chemical composition, can effective kill pests, and the vexed canopy of high temperature can make the abundant fermentation maturity of fertilizer, kills a large amount of worms source.

Embodiment

[embodiment 1]
