Abstract

The invention provides a disease and pest prevention and control method for pollution-free lettuce. The disease and pest prevention and control method for the pollution-free lettuce comprises the steps of A processing seeds, wherein the lettuce seeds are dried in the sun for 3-4 days before being planted firstly, the lettuce seeds are soaked in warm water at the temperature of 40-55 DEG C for 10-15 minutes secondly, the lettuce seeds are soaked in 12% trisodium phosphate for 10-15 minutes and washed with clear water, the lettuce seeds are mixed with common cnidium fruit powder, and then the mixture is reserved; B disinfecting soil, wherein formalin is diluted 40-60 times with water and then is sprayed onto the bed soil, 50-60 milliliters of formalin is consumed per square meter, and then the bed soil is covered with a film for 3-4 days and is dried for 6-8 days; C conducting high-temperature sterilization and disinfestation, wherein after a preceding crop is harvested, stubble is not removed, a greenhouse is fully sealed day and night for 7-10 days, the temperature in the greenhouse is controlled to range from 60 DEG C to 80 DEG C, then the stubble in the greenhouse is removed, water is spayed onto organic fertilizer, the organic fertilizer is wet, piled up and covered with a plastic film before fertilizer application, and the temperature ranges from 60 DEG C to 80 EDG C. The disease and pest prevention and control method for the pollution-free lettuce comprises the steps of processing seeds, disinfecting the soil, conducting high-temperature greenhouse sealing sterilization and disinfestation and the like, pests can be effectively killed without any chemical component; the fertilizer can be fully fermented and become thoroughly decomposed due to high-temperature greenhouse sealing, and a great number of pest sources are killed.

Description

The diseases and pests controlling method of nuisanceless romaine lettuce

 

Technical field:

The present invention relates to horticulture technique, particularly a kind of diseases and pests controlling method of nuisanceless romaine lettuce.

 

Background technology:

Pollution-free vegetable refers to the vegetables that polluted by harmful substance, that is to say that in commodity vegetables, not containing some regulation is forbidden the noxious material containing, within will being controlled at the standard of permission to some inevitable harmful substance.Greengrocery is to provide the main source of people's dietary fiber, vitamin and mineral element, therefore around the content of this three constituents and the quality characteristic of various vegetables, evaluates their nutrition height.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 assurance.

 

Summary of the invention:

The invention provides a kind of diseases and pests controlling method of nuisanceless romaine lettuce.

Technical scheme of the present invention is comprised of following steps:

1, a diseases and pests controlling method for nuisanceless romaine lettuce, is characterized in that being comprised of following steps:

A, seed treatment

Before cultivation, first romaine lettuce seed was shone after 3～4 days, then use 40-55 ℃ of water seed soaking 10～15 minutes; Then with 12% tertiary sodium phosphate seed soaking, after 10～15 minutes, with clear water, clean; After stirring with Common Cnidium Fruit, standby;

B, soil disinfection

40～60 times of formalin dilute with waters are sprayed to bed soil afterwards, and every square metre of formalin 50～60m1 for soil, then covers 3～4 days with film, then airing 6～8 days;

C, high temperature sterilization deinsectization

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