Abstract
The present invention belongs to the field of plant disease preventing and treating technology. The technological scheme of preventing and treating soft rot of konjak with acid matter includes diluting acid matter with water to pH 3-5, applying diluted acid matter to land in the amount of 0.5-1.5kg each hole in 2-4 days before seeding konjak, soaking konjak seed with diluted acid matter for 3-5 hr, and applying diluted acid matter to the root part of konjak in 8-12 days after seedlings come out in the amount of 0.3- 0.6kg. each plant. The said method has obvious effect in preventing and treating soft rot of konjak, low cost, simple operation and high safety.
Description
Technical field
The invention belongs to the control of plant disease field, be specifically related to a kind of method with acidic materials control konjak soft rot.
Background technology
Konjaku has use value widely in methods such as edible, medicine, industry, can produce very big economic benefit.Because its kind planting management is comparatively easy, output value height, the huge market demand, many years ago, just grab it in many places as an industry, but up to the present, the plantation of konjaku is slower development then, and its one of the main reasons is exactly because the harm of konjaku disease.In the konjaku disease, the most serious with the harm of konjak soft rot.According to investigation in Yunnan Province, generally plant the plot of konjaku, this disease incidence of disease reaches more than 20%, the plot of serious morbidity, even total crop failure, serious blow konjaku grower's enthusiasm, seriously hindered the development of konjaku industry.
To the control of konjak soft rot, the general at present measure of adopting is cultural control and chemical control, and the cultural control effect is little, so the measure of adopting in the actual production mainly is chemical control.Be used to prevent and treat this sick medicament, a class is an agricultural chemicals, and a class is an alkaline matter.Use pesticide control, the one, there is the problem of residue of pesticide, the 2nd, do not find control efficiency medicament preferably so far as yet, comparatively speaking, agricultural streptomycin has certain control efficiency, but poor effect, and cost is too high, and the grower is difficult to accept.The alkaline matter control is adopted quicklime and big alkali more, but in fact be there is no what effect.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of existing konjak soft rot Prevention Technique, with a kind of easy and simple to handle, cost is low, control efficiency good, the method that helps environmental protection is prevented and treated konjak soft rot.
The solution of the present invention step is: 1, select land readjustment, be fit to the field piece of konjaku growth; 2, adopt local plantation specification and Fertilization Level; 3, Li Gou beats the pool; Acidic materials are converted water be diluted to PH3～5, in preceding 2～4 days of sowing, every pool poured into 0.5～1.5 kilogram of oxalic acid after the dilution; 4, select the intact taro kind of profile, the acidic substance diluent good with dilution soaked the taro kind 3～5 hours; 5, pull the taro kind out, dry the back sowing; 6, treat that konjaku emerged 8～12 days, with the acidic substance diluent pouring konjaku shoot root portion of PH3～5, every strain consumption is 0.3～0.6 kilogram.Wherein: described acidic materials are oxalic acid, also can be hydrochloric acid.Acidic materials are converted water and are diluted to PH3～3.5, also can be diluted to PH4.5～5.
Beneficial effect of the present invention: in a single day konjaku is infected by Bacteria erwinia, promptly is difficult to survival, and the important method that people prevent and treat konjak soft rot is to use quicklime and big this class alkaline matter of alkali, does not receive what actual effect.General bacterium comparatively is afraid of acid, and acid can suppress the growth of bacterium, and konjak soft rot is because infecting of bacterium just can obtain good preventive effect so use suitable acidic materials.Oxalic acid or hydrochloric acid are easy to obtain, and market price is very low, and when oxalic acid or hydrochloric acid were used the control konjak soft rot, expense was cheap, simple to operate, safety, helps environmental protection.No matter do still interplanting only, no matter sandy loam or red soil, no matter temperature is higher still lower, and no matter rainfall is richer, or rainfall is less, with all obtaining very remarkable prevention effect after oxalic acid or the salt acid treatment.
Embodiment
Be described in further detail the present invention with embodiment below, but content of the present invention is not limited thereto.
Establish three kinds of processing for every group: oxalic acid or hydrochloric acid, agricultural streptomycin and clear water (contrast) are handled, and four repetitions are established in every processing.
Embodiment one:
1, land readjustment is fit to the field piece that konjaku is grown;
2, adopt local plantation specification and Fertilization Level;
3, Li Gou beats the pool; Oxalic acid is converted water be diluted to PH5, in preceding 2 days of sowing, every pool poured into 0.5 kilogram of oxalic acid after the dilution;
4, select the intact taro kind of profile, the oxalic acid diluent good with dilution soaked the taro kind 3 hours;
5, pull the taro kind out, dry the back sowing;
6, treat that konjaku emerged 8 days, with the oxalic acid diluent pouring konjaku shoot root portion of PH5, every strain consumption is 0.3 kilogram.
Embodiment two:
Step is as implementing one.Oxalic acid is diluted to PH3, and in preceding 4 days of sowing, every pool poured into 1.5 kilograms of oxalic acid after the dilution; The oxalic acid diluent good with dilution soaked the taro kind 5 hours; Pull the taro kind out, dry the back sowing; Treat that konjaku emerged 12 days, with the oxalic acid diluent pouring konjaku shoot root portion of PH3, every strain consumption is 0.6 kilogram.
Embodiment three:
Step is as implementing one.Oxalic acid is diluted to PH4, and in preceding 3 days of sowing, every pool poured into 1 kilogram of oxalic acid after the dilution; The oxalic acid diluent good with dilution soaked the taro kind 4 hours; Pull the taro kind out, dry the back sowing; Treat that konjaku emerged 10 days, with the oxalic acid diluent pouring konjaku shoot root portion of PH4, every strain consumption is 0.5 kilogram.
Embodiment four:
Step is as implementing one.Hydrochloric acid is diluted to PH5, and in preceding 2 days of sowing, every pool poured into 0.5 kilogram of hydrochloric acid after the dilution; The hydrochloric acid dilution good with dilution soaked the taro kind 3 hours; Pull the taro kind out, dry the back sowing; Treat that konjaku emerged 8 days, with the hydrochloric acid dilution pouring konjaku shoot root portion of PH5, every strain consumption is 0.3 kilogram.
Embodiment five:
Step is as implementing one.Hydrochloric acid is diluted to PH3, and in preceding 4 days of sowing, every pool poured into 1.5 kilograms of hydrochloric acid after the dilution; The hydrochloric acid dilution good with dilution soaked the taro kind 5 hours; Pull the taro kind out, dry the back sowing; Treat that konjaku emerged 12 days, with the hydrochloric acid dilution pouring konjaku shoot root portion of PH3, every strain consumption is 0.6 kilogram.Comparing result:
Each medicament is to the control efficiency of konjak soft rot
| Handle | The average diseased plant rate of each group (%) | ||||
| Embodiment one | Embodiment two | Embodiment three | Embodiment four | Embodiment five | |
| Agricultural streptomycin oxalic acid hydrochloric acid clear water (contrast) | 17.25 3.75 25.5 | 15.25 2.0 24.75 | 12.5 2.5 22.25 | 19 3.50 28.5 | 18.5 1.75 26.75 |
From as can be seen above: with acidic materials konjak soft rot is prevented and treated, can be obtained the control efficiency of highly significant than traditional method.
