Abstract

The invention relates to a method for preventing and controlling ginger blast, and mainly solves the problems that the existing preventing and controlling technology pollutes and damages the soil structure. The method is characterized in that: I, adopting the biological bacteria of the following amount: (1) 500-900 g of primary bacillus subtilis per mu, (2) 10-30 g of pythium oligadrum per mu, and (3) 1000-2000 g of flora consisting of phosphorus-dissolving bacteria, potassium dissolving bacteria, actinomycetes, antibiotic bacteria, nitrobacteria, photosynthetic bacteria, aspergillus, streptomyces and live beneficial fungi; II, adding 500 kg of fermentation soybean cake or 4 square meters of fowl manure into (3) of I, and fermenting for 8-10 days; III, before planting ginger, mixing (1) and (2) of I proportionally, and irrigating the plot; IV, after planting ginger, mixing (1) and (2) of I proportionally, and irrigating the plot at an interval of 20 days; and V, when seeding ginger and topdressing, uniformly scattering the fertilizer made by II. The method provided by the invention is scientific and reasonable, effectively improves soil and has obvious effect of above 90% in preventing and controlling ginger blast; and moreover, the method has certain effect in preventing and controlling ginger rhizome rot, and reduces the cost by **** in comparison with the prior art.

Description

A kind of method of preventing and treating bacterial wilt of ginger

Affiliated technical field

The present invention relates to the method for the control bacterial wilt of ginger in a kind of agriculture Da Jiang planting technology.

Background technology

Bacterial wilt of ginger is the rot of ginger, is a kind of bacterial disease.Mainly cause harm basal part of stem and stem tuber with face of land handing-over.The disease portion initial stage shows as filemot water stain shape, and sick portion enlarges gradually and becomes crineous, and ginger block organization is softening, rots.Organize routedization with hand once squeezing, become the liquid of one white thick tool foul odour.Browning only stays one deck epidermis after rotting when serious, then dehydration flavescence of overground part (Jiang Miao), and browning is withered.The control bacterial wilt of ginger can be taked following measure: 1, carry out the crop rotation of 2-3 with other crops, except that avoiding continuous cropping, also should avoid and the solanaceous vegetable crop rotation, best and gramineous crop crop rotation.2, should reserve seed for planting from anosis Tanaka, before the plantation, plant the ginger sterilization of should soaking seed.Also can on the tangent plane of kind of ginger, seal kind of a ginger wound by libation at an ancient wedding ceremony ash, avoid germ to invade.3, should take bedding cultivation, note draining.4, when just fall ill in the field, should pull out diseased plant immediately, in the strain cave with ash or lime disinfection.Diseased plant of pulling out and sick soil should be taken out of outside the field, and other healthy plant keep off infection.5, handle diseased plant after, carry out field spray medicine.Spendable medicament has: 77% can kill 600 times of liquid of (101) micro mist grain, 600 times of liquid of 30%DT bactericide; 600 times of liquid of 70% fenaminosulf wetting powder; [401] 500 times of liquid of antibacterial agent, 1000 times of liquid of 50% ambam also can use 1: 1: 200 times of bordeaux mixture.During the spray medicine, should spray basal part of stem, and soup is seeped on the rhizome.Once sprayed 2-3 time in 7-10 days altogether at the interval.Above-mentioned way has certain effect to the control bacterial wilt of ginger, but can not thoroughly prevent and treat, if because the ginger plague germ that contains in the soil hides in the ginger piece; Medicine can't be invaded, and the treatment difficulty produces effect, so bacterial wilt of ginger is relied mainly on prevention; Need mainly take to utilize hypertoxic medicines such as chloropicrin, Celfume to soil-fumigating to soil disinfection for this reason, when killing harmful bacterium, kill profitable strain; Make the soil ecology dysequilibrium, lost the conversion of beneficial bacterium, influence growth and development of plants soil and fertilizer; Because beneficial bacterium can not constrain harmful bacterium, harmful bacterium is bred in a large number, the later stage is caused the heavy damage of soil structure, and the every condition of plant growth is following, forms vicious circle.Severe contamination has been gone back in the use of said medicine underground water and air is left a legacy of trouble to serious.

Summary of the invention

The present invention provides a kind of method of new control bacterial wilt of ginger, asks v topic with what overcome that existing Prevention Technique pollutes, destroys soil structure, realizes that control efficiency is good, the purpose of the ecotope of improving the soil.

The present invention is according to the principle of " control bacterium with bacterium, adjustment soil structure ", and concentrating on studies surplus the applicant ten year obtains mature technique.

Technical scheme of the present invention: one, the present invention adopts following biological bacteria and content: 1, every mu of bacillus subtilis starter bacterium 500-900 gram; 2, every mu of pythium oligandrum bacterium 10-30 gram: 3, the flora 1000-2000 gram of phosphorus-solubilizing bacteria, retired bacterium, actinomycetes, antibiotic bacteria, nitrifier, light and bacterium, Aspergillus, streptomycete, the beneficial fungi composition of living; Two, mix 500 kilograms of fermentation soya-bean cakes or chicken manure 4 sides with above-mentioned one (3), fermented 8-10 days.Three, do not plant before the ginger, with above-mentioned one (1), (2) be mixed the pouring plot in proportion; Four, behind the ginger cultivation, with above-mentioned one (1), (2) be mixed in proportion, 20 days are at interval, the pouring plot; Five, ginger sow, when topdressing, with the two even spreadings of fertilizer made.

The inventive method is scientific and reasonable, improves the soil effectively, and is obvious to the bacterial wilt of ginger control efficiency, can reach more than 90%; The present invention also has certain control efficiency to ginger root-stem rot; Than every mu of the prior art 1500-3500 unit that reduces cost.

Instance 1:

1,, gets female bacterium 900 grams of bacillus for every mu; Get pythium oligandrum bacterium 30 grams for every mu; 2, flora 2000 grams of getting phosphorus-solubilizing bacteria, retired bacterium, actinomycetes, antibiotic bacteria, nitrifier, light and bacterium, Aspergillus, streptomycete, the beneficial fungi composition of living mix 500 kilograms of fermentation soya-bean cakes or chicken manure 4 sides, ferment 10 days; 3, do not plant before the ginger, be mixed pouring plot one time above-mentioned 1; 4, behind the ginger cultivation, 20 days at interval, pouring plot three times; Five, ginger sow, when topdressing, with 2 150 kilograms of even spreadings of soya-bean cake of fertilizer of making.This plot reaches 99% to the control rate of bacterial wilt of ginger.Every mu of ground prevents and treats 590 yuan of costs.

Instance 2:

Making and use method is with instance 1.

Female bacterium 500 grams of bacillus; Get pythium oligandrum bacterium 10 grams for every mu; 2, get flora 1000 grams of phosphorus-solubilizing bacteria, retired bacterium, actinomycetes, antibiotic bacteria, nitrifier, light and bacterium, Aspergillus, streptomycete, the beneficial fungi composition of living.This plot reaches 90% to the control rate of bacterial wilt of ginger.Every mu of ground prevents and treats 280 yuan of costs.

Instance 3

Making and use method is with instance 1.

Female bacterium 600 grams of bacillus; Get pythium oligandrum bacterium 20 grams for every mu; 2, get flora 1500 grams of phosphorus-solubilizing bacteria, retired bacterium, actinomycetes, antibiotic bacteria, nitrifier, light and bacterium, Aspergillus, streptomycete, the beneficial fungi composition of living.This plot reaches 95% to the control rate of bacterial wilt of ginger.Every mu of ground prevents and treats 410 yuan of costs.
