Abstract
A rotting disease prevention new technology for a peanut rot rotting stem is characterized by comprising technologies of crop rotation, seed management, seed processing before broadcasting, deep tillage and soil overturning, cultivation management with fertilizer and water as the center and chemical control. By the use of the new technology, disease spreading and propagation path for soil with bacteria, seeds with bacteria and manure with bacteria can be prevented, so peanut growth potential can be improved and disease resistance capacity can be enhanced; and the new technology is suitable for prevention of rotting disease for peanut root rotting stem.
Description
Technical field
The present invention relates to peanut cultivation field, specifically a kind of Roots of Peanut maize ear rot stem rot preventing and treating new technique.
Background technology
At present, owing to Semen arachidis hypogaeae is planted year after year, the soil-borne disease such as Roots of Peanut maize ear rot, stem rot becomes Common Diseases, occurs very general, and hazard ratio is more serious, particularly continuous cropping plot, occurs to increase the weight of year by year, has had a strong impact on the yield and quality of Semen arachidis hypogaeae. Its hazard symptoms is as follows:
1, Roots of Peanut maize ear rot. Being commonly called as " rat-tail ", each period of duration all can be fallen ill. Semen arachidis hypogaeae is caught an illness before emerging after broadcasting, and infects the seed of just sprouting, causes rotten kind not emerge; Seedling is injured, main root browning, and plant withers; Strain is injured, and main root rhizome occurs depression strip brown scab, and butt rot is easily peeled off, and does not have side root or little, is similar to rat-tail. Plant is short and small on the ground, and blade is yellow, yields positive results few, and mostly is not plump fruit.
2, Diplodia gossypina. It is commonly called as seedling laying disease, pinches neck pestilence. Peanut growth early stage and morbidity in mid-term, the blackening of cotyledon elder generation is rotted, then subaerial basal part of stem and subterraneous stem are infected, be just water soaking mode yellowish-brown scab, after gradually around stem or to rhizome extension formation pitchy scab, aerial parts blade shoals jaundice, noon beats listless, within second day, recovering again, during serious morbidity, Herb is wilted, withered.
Summary of the invention
Present invention seek to address that Roots of Peanut, stem rot are fallen ill on continuous cropping plot heavy; Soil layer is shallow, chiltern ground, low fertility ground, and peanut growth is weak, premunition difference morbidity weight; Spring sowing Semen arachidis hypogaeae, especially sows root rot morbidity weight on plot early; Seedling stage many wet weather, high humidity time root rot morbidity weight. Mulching film peanut root, stem, fruit disease generally occur, and general diseased plant rate reaches 3%��15%, serious reach the problem such as 80%.
1, crop rotation is carried out. The next year crop rotation of hypopathia field, severe disease field crop rotation 3��5 years. With the gramineous crop crop rotation such as Semen Tritici aestivi, Semen Maydis, it is to avoid and Semen sojae atricolor, Radix Ipomoeae interplanting, a kind.
2, keep well, run seed well. The Semen arachidis hypogaeae done kind to be gathered in the crops in time, dries in time, leaves ventilation, dry place, moistureproof, mildew-resistant in.
3, front seed treatment is broadcast. Selected disease-free seed before sowing, basks seeds, carries out seed treatment simultaneously, and when 50% carbendazol wettable powder of available seed weight 0.3��0.5% is dressed seed or fits happy with 2.5%, seed coat agent is by 1:500(medicine: plant) carry out coating.
4, plough deeply and improve the soil. Timely soil deeptillage after harvesting peanut, to eliminate pathogenic bacteria partial wintering, finely wholely, improves seeding quality.
5, the cultivation management centered by rich water is done a good job of it. The rational application of fertilizer, notes using clean fertilizer, enriches the fertilizer become thoroughly decomposed, impose plant ash; Regulation irrigation and drainage system, improves prevention waterlogging drought-resistant ability, timely ditch cleaning row stain wet down after rain;In peanut growth season, weeding in time, short Seedling is early sent out, and robust growth strengthens Semen arachidis hypogaeae resistance against diseases. Pull out field diseased plant in time, take out of and destroy outside field.
6, chemical prevention. After the neat Seedling of Semen arachidis hypogaeae, strengthening checking, it has been found that prevent and treat immediately after diseased plant, block primary infection focus, mu 500��800 times of liquid of 70% thiophanate methyl wettable powder or 600 times of liquid of 40% tolelofos-methyl fill pier, and interval fills once for 10 days, even fills 2 times.
Technique effect
The solution have the advantages that the disease spread that solution fungus in soil, seed-borne fungi, muck carry disease germs spreads approach, improve Semen arachidis hypogaeae growing way, strengthen premunition.
Detailed description of the invention
1, crop rotation is carried out. The next year crop rotation of hypopathia field, severe disease field crop rotation 3��5 years. With the gramineous crop crop rotation such as Semen Tritici aestivi, Semen Maydis, it is to avoid and Semen sojae atricolor, Radix Ipomoeae interplanting, a kind.
2, keep well, run seed well. The Semen arachidis hypogaeae done kind to be gathered in the crops in time, dries in time, leaves ventilation, dry place, moistureproof, mildew-resistant in.
3, front seed treatment is broadcast. Selected disease-free seed before sowing, basks seeds, carries out seed treatment simultaneously, and when 50% carbendazol wettable powder of available seed weight 0.3��0.5% is dressed seed or fits happy with 2.5%, seed coat agent is by 1:500(medicine: plant) carry out coating.
4, plough deeply and improve the soil. Timely soil deeptillage after harvesting peanut, to eliminate pathogenic bacteria partial wintering, finely wholely, improves seeding quality.
5, the cultivation management centered by rich water is done a good job of it. The rational application of fertilizer, notes using clean fertilizer, enriches the fertilizer become thoroughly decomposed, impose plant ash; Regulation irrigation and drainage system, improves prevention waterlogging drought-resistant ability, timely ditch cleaning row stain wet down after rain; In peanut growth season, weeding in time, short Seedling is early sent out, and robust growth strengthens Semen arachidis hypogaeae resistance against diseases. Pull out field diseased plant in time, take out of and destroy outside field.
6, chemical prevention. After the neat Seedling of Semen arachidis hypogaeae, strengthening checking, it has been found that prevent and treat immediately after diseased plant, block primary infection focus, mu 500��800 times of liquid of 70% thiophanate methyl wettable powder or 600 times of liquid of 40% tolelofos-methyl fill pier, and interval fills once for 10 days, even fills 2 times.
