Wheat is become piece sere, it is do mischief of a kind of disease, farmer friend prevention and cur

Come on Tian Kuai

Uncle of villager the Song Dynasty is in already field wait, he is pointing to oneself wheat to say anxiety-riddenly: "The wheat of my home, mix apparently of neighbour home different, not only whole is not hale, still appear sere hair yellow phenomenon, at present my gush two antiseptic, symptom not only did not reduce, more and more serious instead, want to consult agricultural expert, this wheat is after all how, the idea that still has prophylaxis and treatment? The idea that still has prophylaxis and treatment??

Cause wheat to send yellow reason to have a lot of, the near future is for instance arid, phenomena of a lot of wheaten occurrence precocity (because whole cropland is short of hair of water large area to fizzle out, it is normal to have a green occasionally wheaten) , this kind of wheat does not have ill spot on cauline stalk, root system is regular, blade belongs to dehydration sex sere, be worth wheaten grouting nowadays period, if encounter dry weather and high temperature weather, aggravate of wheaten rising action, cent cannot finish nutrition and water to be carried normally, not only wheaten whole hair is yellow, grow in quantity of phenomenon of not plump wheat, crop gets great influence.

The holiday that wheat causes because of drought is ripe

Below the premise that eliminates drought, plant of wheaten cropland large area is normal, if appear,small area sends yellow sere phenomenon, was about to consider from disease, resemble the wheat of Home Song Dashu, should cause by a kind of disease.

Unplugged a diseased or infected plant, inspection root system does not have illness, cauline radical ministry has ill spot of elliptic cloud shape, can affirm from this, the wheat of Home Song Dashu, be become a hair yellow phenomenon by what wheaten grain withered disease causes.

Wheaten grain withered disease is a kind of earth that often happens spreads sexual disease, include the clothes to wheaten seed as farmer friend in last few years take seriously, withered ill year after year reduces grain, also absolutely, make farmer friend reduced the vigilance of withered to grain disease, once buy Bao Yi's bad seed field perhaps bacteria is more, encounter these two kinds of situations, want to undertake withered to wheaten grain disease prevents ahead of schedule.

Song Dashu

Additional, nitrogenous fertilizer employ is overmuch, sow density too big, sow time humidity of premature, soil is big wait for an element, also can bring about the happening of wheaten grain withered disease, accordingly, seed dressing is a kind of wonderful precaution way, but also not be absolutely safeguard.

Is be what to say seed dressing the means with best precaution of wheaten grain withered disease? Because bacteria of wheaten grain withered disease often is in soil with hypha or bacterium nucleus wait for one's chance commits the crime,this is, can live through the winter also can be jumped over summer, once encounter wheaten seed, it began to do it, so, take the step of wheaten Bao Yi, can prevent the be contaminated of bacteria of grain withered disease.

Wheaten grain withered disease is not behaved only in seedling stage, whole growth period can happen, the wheat of Home Song Dashu belongs to later period to come on, be contaminated of bacteria of grain withered disease enters cauline stalk, make moisture and nutrition loose suffocate suffocate, bring about plant thereby hair is yellow, Gan Sui, withered dead.

Diseased or infected plant is comparative

Withered ill prevention and cure should act on wheaten grain " prevent ahead of schedule, early discovery early treatment " principle, plant through using in suspension of Zun of annulus of benzene aether armour clothing medicine or Zun of annulus of benzene aether armour + in suspension of nitrile of cough up bacterium is planted the means of clothing medicine seed dressing,

The seedling stage after the Spring Festival but gush applies spirit of bacterium of Zun of annulus of armour of aether of amine of Sai Fu acyl, benzene, methylic sulfur to wait undertake prevent or be remedialed, basic controallable the happening of wheaten grain withered disease.

It is the wheat of Home Song Dashu only, had belonged to later period catch a disease, bacteria already immerge bine stalk, at that time again gush drug treatment, already at job of no help, had lost value of prevention and cure that is to say, this is crop prevents the value that controls plant diseases and insect pests to be in ahead of schedule.

State of grain withered disease

To the precaution of grain withered disease, besides the measure that adopts chemical pesticide prevention and cure, farmer friend still can be passed in increasing soil organic qualitative content, timely sow, the happening that the choice fights the means such as breed of wheat of grain withered disease to reduce grain withered disease, on this foundation, cooperate chemical pesticide prevention and cure, send an area high in wheaten grain withered disease especially, this is step of a kind of more significant prevention and cure.
