Abstract

The invention provides a disease prevention method for pollution-free organic celery. The disease prevention method comprises the following steps: A, seed treatment: firstly sunning celery seeds for 3-4 days before cultivation, then soaking the seeds for 10-15 min with warm water at a temperature of 38-48 DEG C; then soaking the seeds for 10-15 min with 13% sodium carbonate and then washing with clean water; and airing for use after stirring with carbendazim powder; B, soil disinfection: diluting formalin with water by 40-70 times to obtain a diluted liquor, spraying the liquor on bed soil, wherein 50-60 ml of the diluted liquor is used in every square meter of the soil; then overlaying for 3-4 days with a thin film, and then airing for 8-9 days; C, high-temperature sterilization deinsectization: after harvesting preceding crops, firstly completely closing the shed room without removing stubble, wherein the shed room is closed for 7-10 days all day long, and the temperature inside the shed room is controlled to be 70-80 DEG C; then removing the stubble inside the shed room; and sprinkling water to wet a mat before a fertilizer application, piling and overlaying a plastic film, controlling the temperature to be 70-80 DEG C. The disease prevention method for celery provided by the invention comprises the seed treatment, the soil disinfection, the high-temperature sterilization deinsectization and the like; injurious insects can be effectively killed without any chemical component; fertilizers can be sufficiently fermented and decomposed through the high-temperature closed shed room; and a large number of insect sources are killed.

Description

A kind of prevention of damage by disease method of nuisanceless organic celery

Technical field:

The present invention relates to horticulture technique, particularly a kind of prevention of damage by disease method of nuisanceless organic celery.

Background technology:

Pollution-free vegetable refers to not by the vegetables that harmful substance is polluted, and in truck, does not that is contain the noxious material that some regulation is forbidden to contain, then will control within the standard allowed some inevitable harmful substance.Greengrocery is to provide the main source of people's dietary fiber, vitamin and mineral element, therefore evaluates their nutrition height around the content of this three constituents and the quality characteristic of various vegetables.As can be seen here, pollution-free vegetable is not only and realizes the most basic material resources of Green Foodstuff Project, but also is one of important component part of agricultural sustainable development and environment for human survival guarantee.

Summary of the invention:

The invention provides a kind of prevention of damage by disease method of nuisanceless organic celery.

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

1, a prevention of damage by disease method for nuisanceless organic celery, is characterized in that being made up of following steps:

A, seed treatment

First celery seed is shone 3 ~ 4 days before cultivation after, then use 38-48 DEG C of water seed soaking 10 ~ 15 minutes; Then clean with clear water after 10 ~ 15 minutes with 13% sodium carbonate seed soaking; After stirring with powder of carbendazim powder, dry for subsequent use;

B, soil disinfection

Formalin dilute with water 40 ~ 70 times is sprayed afterwards bed soil, every square metre of soil formalin 50 ~ 60m1, then uses plastic film covering 3 ~ 4 days, then airing 8 ~ 9 days;

C, high temperature sterilization deinsectization

After first crop crop harvesting is complete, first do not remove stubble, canopy room is all airtight, vexed canopy 7 ~ 10 days round the clock, canopy indoor temperature controls, at 70 ~ 80 DEG C, to remove stubble in canopy more afterwards; Mix wet by straw screen or mat water-sprinkling before fertilising, pile up and cover tightly plastic film, temperature keeps 70 ~ 80 DEG C.

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 worm source.

Embodiment:
