Description
Technical field
The invention belongs to agricultural practicality new technique research and development and application；The present invention relates to a kind of vegetable seedling damping off control agent
Research and development and production application method.
Background technology
Vegetable seedling damping off, is commonly called as " Seedling ", " mould ", " bound feet pestilence ", belongs to fungal disease, by Mastigomycotina melon
Fruit pythium (Pythium), Phytophthora (Phytophthora), silk core belong to the Seedling that fungal attack such as (Rhizoctonia) causes
Phase plant disease, is the disease of early spring vegetable in seedling period most serious, can affect growth of seedling, cause to be short of seedling or even ruin when serious
Kind.
Vegetable seedling damping off pathogenic bacteria host range is very wide, including vegetables such as leaf vegetabless, melon, solanaceous vegetables, beans, root vegetableses
The seedbed disease of dish seedling, can cause dead seedling in blocks when serious.Southern area winter-spring season air and soil moisture are all very big, especially
It is that in hot house, humidity many places, in hypersaturated state, are particularly suitable for the generation of damping off, some this diseases of vegetable grower Chang Yin and damage
Lose heavy, thus, govern the development of southern area booth vegetable.
It is in water stain shape deliquescing that vegetable seedling damping off infects the basal part of stem that Symptoms are seedling, wilts rapidly therewith,
Basal part of stem is hung in wire contracting afterwards；Sometimes cotyledon not yet shows symptom and lodges, and therefore named dampings off.Most common with 3-5 leaf seedling.By
The seedling diseases that rhizoctonia causes is commonly referred to as damping-off, and aggrieved seedling basal part of stem produces brown scab, gradually make young stem atrophy until
Seedling is withered, is infected cotyledon and also can produce the difform scab of brown, seedling is mostly susceptible from basal part of stem（Also have from stem
Patient is felt in portion）, just for water stain shape, and extension, contracting of overflowing attenuate such as " line " sample quickly, sick portion invariant color or be in yellowish-brown, and patient's condition is sent out
Exhibition is rapid, i.e. from basal part of stem before cotyledon is still green, wilts（Or in the middle part of stem）Lodge and be affixed on bed surface.During the high humidity of seedbed,
One fleece shape white mould can be given birth on invalid body and surrounding bed soil.Catch an illness before emerging, cause cotyledon, young root and young stem browning to rot, that is,
For rotten kind or rotten bud.Disease starts often only indivedual seedling morbidities, when condition is suitable for centered on these diseased plants, rapidly to surrounding
Extension spreads, and forms one piece one piece of lesion.There is relatively universal, pythium spp in the damping-off of Solanaceae, crop in cruciferae and cotton Seedling
It is all soil inhabitant with Rhizoctonia solani Kuhn, is a class weak parasite, host range is wider.Damping off pathogenic bacteria is with mycelium or bacterium
Core saprophytic or survival in invalid tissue in soil, as the primary infection source of Infection cycie.Pythium spp and phytophthora also may be used
Survived the winter in residuum or in soil by oospore or akinete and tide over bad environmental condition.Pathogenic bacteria mainly pass through pour water or
Soil cultivation is propagated.The growth suitable temperature range of pathogen is larger.When seedling bearing status are bad, resistance is poor, with regard to susceptible disease.Sudden
Fall disease sometimes even the moon cruelly fine, suddenly throw off covering when unexpected large area occur.Damping off is often to send out, extensively in various vegetables seedling stage
Send out, one of multiple most serious disease, all there is generation all parts of the country, and the loss causing is very big.
At present, although the domestic research to the preventing and treating of vegetable seedling damping off is many with report, its effective means is subject to many
Limitation, effect is also not satisfactory.Traditional prophylactico-therapeutic measuress are mainly by good soil cultivation；Avoid soil's being over wet；Strengthen seedling stage pipe
Reason；Strengthen seedling resistance；Broadcast front soil disinfection；Chemical pesticide is sprayed after emerging；Rationally heavy seeding；Timely and appropriate discovery topdresses, waters；
Avoid using old bed soil nursery simultaneously, note seedbed cleaning and carry out soil disinfection；Just can only spray various once morbidity
Chemical pesticide, but its effect is very poor, and it is observed that sometimes even not seeing effect, disease continues to quickly spread.
The above cultivation step is not only time-consuming to take a lot of work, and its effect is often not satisfactory；Apply after particularly falling ill
Pure chemistry pesticide and antibacterial, often cannot stop disease continue spread.The pre- of this vegetable seedling damping off control agent controls effect
Fruit is all extremely notable, and premorbid uses, and can prevent to fall ill；Apply after morbidity, can comparatively fast stop disease from spreading, seedling recovers normally to give birth to
Long fast.This vegetable seedling damping off control agent is the achievement through research for many years and production application, and it both can be prevented, can control again, and make
With convenient, simple to operate, low cost, prevention effect is notable, this be other about medicament or measure cannoted than.
Need it is emphasized that the calcareous quick lime powder of this vegetable seedling damping off control agent can not use calcareous ripe stone instead
Grey powder or magnesium lime or containing the lime particle that overdoes, albefaction vegetation ashes can not use instead it has often been said that plant ash（Black）,
Otherwise, its effect will be had a greatly reduced quality, the pure chemistry pesticide that might as well commonly use now and antibacterial.
