Description

A kind of method of preventing and treating of Winter Wheat Root maize ear rot

Technical field:

The present invention relates to crop disease control technical field, be specifically related to a kind of method of preventing and treating of Winter Wheat Root maize ear rot.

Background technology:

Root rot is to be caused by standing grain cochliobolus, a kind of fungal disease of root, stem, leaf, fringe and the seed of the wheat seedling of causing harm, strain.Root rot distributed pole is wide, wheat planting is national all a generation, and China mainly occurs in the areas such as northeast, northwest, North China, the Inner Mongol, constantly expands in recent years, and Guangdong, Fujian Mai Qu are also found.

Pathogen is that [Cochliobolus sati-vu (Ito et Kurib.) Drechsl. root rot occurs heavy standing grain cochliobolus when soil is too arid or moist; The seedling aggravation of enduring cold.The leaf portion morbidity of strain phase is relevant with weather, host's fertility status and leaf age.The generation development of root rot is subject to various factors, and as soil compaction, during sowing, earthing is blocked up, and the factors such as continuous wheat and seed-borne fungi all can promote the rotten generation of seedling.The strain phase spatial distribution of blade morbidity is S shaped form, and the initial stage state of an illness increasess slowly, and rapidly, the later stage is steady in development in mid-term.The leaf portion state of an illness and germ density, meteorological condition and host resistance are closely related.Wheat is given birth to temperature in early stage, humidity is low, and bacterium source amount is little, fall ill gently, and heading front vane better resistance, state of an illness growth rate is slow, and after heading, resistance declines, and temperature, humidity raise, and after repeatedly infecting, bacterium source amount increases again, the state of an illness increases rapidly, and after milk ripe stage, growth rate slows down.

And for root rotof flax, because mostly the disease of this class is a long time ago just to occur, in the process of control, common method or the method that some are simple and common just do not have very good effect like this, will lose time like this, material resources.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency a kind of method of preventing and treating that method is reasonable, implement simple, respond well a kind of Winter Wheat Root maize ear rot is provided.

Technical problem to be solved by this invention adopts following technical scheme to realize:

The method of preventing and treating of Winter Wheat Root maize ear rot, is characterized in that: comprises the following steps,

Step 1, plough deeply: after autumn harvest, soil is ploughed deeply, and imposed farmyard manure simultaneously, and the crop rotation of suiting measures to local conditions;

Step 2, seed treatment: select resistant variety.The 2-3 days that basks seeds before broadcasting, in strict accordance with the seed dressing of seed dressing program, when suitable happy or defend good fortune by the 2%-3% seed dressing of grain weight, vexed kind of 12-24 hour;

Step 3, the rational application of fertilizer: to use well-rotted farmyard manure as main, balance fertilizing, promotes fertilization compositions based on earth measurement.Rationally, with potash fertilizer, zinc fertilizer, boron fertilizer, calcareous fertilisers etc., control the consumption of nitrogenous fertilizer;

Step 4, management before the winter: wheat emerge after according to wheat seeding growing way, plant growth regulator and the systemic fungicides such as weak wheat seeding foliage-spray 1 hypophosphorous acid potassium dihydrogen, green power.Field 70% thiophanate methyl 70g or 500 times of liquid of 50% carbendazol wettable powder that root rot occurs mix green power, potassium dihydrogen phosphate carries out foliage spray;

Step 5, winter irrigation management: entering before the winter to carry out a winter irrigation, after the beginning of spring in the coming year, plough in the spring once, in the water of gravying with meat or vegetables poured over rice or noodles before early April, application of phosphoric acid potassium dihydrogen or humus, amino acid fertilizer;

Step 6, anti-duct ligation close: at the initial stage of a disease, select 12.5% to close the spraying of sharp wetting powder 2500-3000 times of liquid of fruit, or every mu of use 4.5% jade buries that bacterium kills aqua 30-35g or 5% jinggangmeisu aqua 10g adds water 40kg spraying control, every 7-10 days, spray once again.At wheat, turn green to the shooting stage, every mu of use 50% strong fungicide 50ml, character used in proper names and in rendering some foreign names nurse 5ml, add water 40kg spraying, every spray in 7-10 days 1 time, prevents and treats 2-3 time continuously.At the wheat flower initial stage, every mu of use 25% triadimefon wetting powder 100g adds water spray.

Beneficial effect of the present invention is: very simple, easy-to-understand of above-mentioned step, and very clear, is applicable to specialty or common staff's reference and use, and the medicament using etc. is all more common, such medicament reasonable price, can not bring burden economically.Method of the present invention rationally, implement simple, respond well.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

The method of preventing and treating of Winter Wheat Root maize ear rot, is characterized in that: comprises the following steps,
