Abstract
A continuous cropping cultivation method for yams is characterized by comprising steps of disinfecting soil; disinfecting tips of the yams by disinfectants; leveling a bed surface before colonization; and controlling the anthracnose, the fusarium wilt and the brown rot for the yams. By the continuous cropping cultivation method, the yam continuous cropping cultivation success rate can reach 90% at least.
Description
The present invention relates to the planting technology, particularly a kind of Chinese yam continuous crop method.
Background technology
Yam planting in the existing history for a long time of China, is medicine food double-purpose plant, and the yam planting area enlarges year by year in recent years, and the key of restriction Chinese yam large-scale production is can not continuous cropping, can not continuous cropping be the bottleneck of yam planting.Chinese yam is afraid of continuous cropping most, by a piece of land, if continuous 2 years plantation Chinese yams continued plantation on the 3rd year again, if do not take measures to process, will inevitably occur more dead.This invention just is to provide a kind of Chinese yam continuous crop method.
Summary of the invention
Technical scheme of the present invention is to realize like this.A kind of Chinese yam continuous crop method is characterized in that comprising the following steps: (1) soil disinfection, and (2) Chinese yam mouthpiece pharmacy disinfection will flatten the furrow face before (3) field planting, and (4) prevent and treat anthracnose, fusarium wilt, three kinds of diseases of brown rot.Soil disinfection refers to into ploughing deeply in the plot of preparing the plantation Chinese yam before the winter, wide 15-25cm, dark 80-100cm ditch, sprinkle in the soil when digging before field planting and dislike any in mould spirit, tmtd, promise good fortune silver ion disinfectant, partile cyanamid, plant again Chinese yam after mixing with soil.Chinese yam mouthpiece pharmacy disinfection method is to soak with the mould clever 2500--3500 of 2500--3500 times of liquid+evil of thiophanate methyl wetting powder times liquid+root-growing agent.Chinese yam anthracnose, leaf spot lesion is brown, scattered black small grain point on spot, the climing scab pitchy of stem, slightly cave in, scab on blade or stem are climing produces pink sticky material often there was dampness in the air, and this disease blade of causing harm when serious is caducous, stem is climing withered, cause plant dead, their early stage mixes 500 times of liquid of tmtd with carbendazim, or the mixed 500 times of liquid of carbendazim of the mould ketone of thiophene in time spray the medicine control.Fusarium wilt is mainly manifested in the brown scab that the web rot shape appears in the Chinese yam mouthpiece, the whole epidermis of base portion rots, overground part blade yellowing and shedding, tendril is withered rapidly, fills with root with 1000 times of liquid of 50% chlorobromide isocyanuric acid or 600 times of liquid of 40% thiophanate-methyl sulphur suspends or 500 times of liquid of 70% mancozeb.The Chinese yam brown rot piece root of mainly causing harm, general results are seen often, the irregular moth patch of the shape that occurs on the piece potato rotting; depression slightly, sick piece is deformity often, the deliquescing of rot section; this disease must early be prevented, and uses 800 times of liquid irrigating root treatments of 3000 times of liquid of 80% S-Ethyl ethylthio sulfonate or 70% thiophanate methyl.
The method, Chinese yam continuous crop success rate reaches more than 90%.
Embodiment
A kind of Chinese yam continuous crop method, comprise the following steps: (1) soil disinfection, after Chinese yam is gathered in the fall, just will prepare to plant the plot of Chinese yam before entering the winter next year turns over one time, ditch wide 20cm, dark 90cm allow the abundant weathering of soil, the soil of routing up are filled out back in ditch after spring break by the time again, after processing through winter low temperature, the pathogen in soil has just obviously reduced; Sprinkle the mould spirit of evil, tmtd medicament when digging in soil before field planting, plant again Chinese yam after mixing with soil, (2) Chinese yam mouthpiece pharmacy disinfection soaks with the mould clever 3000 times of liquid+root-growing agents of 3000 times of liquid+evils of thiophanate methyl wetting powder, guarantees that the Chinese yam seedling is without germ.(3) will flatten the furrow face before field planting, because drought-enduring the fearnesss waterlogging of Chinese yam happiness light, not flatten if during whole ground, the rear field drainage of watering is not smooth, and Chinese yam is easy to occur yellow leaf bad root phenomenon, finally causes dead.(4) prevent and treat anthracnose, fusarium wilt, three kinds of diseases of brown rot.In summer high temperature rainy season, germ is propagated with rainwater, and dead generation is particularly serious, causes that the disease of dead mainly contains anthracnose, fusarium wilt, these three kinds of diseases of brown rot, therefore, in time sprays medicine, prevents early dead; Chinese yam anthracnose, leaf spot lesion is brown, scattered black small grain point on spot, the climing scab pitchy of stem, slightly cave in, scab on blade or stem are climing produces pink sticky material often there was dampness in the air, and this disease blade of causing harm when serious is caducous, stem is climing withered, cause plant dead, their early stage mixes 500 times of liquid of tmtd with carbendazim, or the mixed 500 times of liquid of carbendazim of the mould ketone of thiophene in time spray the medicine control.Fusarium wilt is mainly manifested in the brown scab that the web rot shape appears in the Chinese yam mouthpiece, the whole epidermis of base portion rots, overground part blade yellowing and shedding, tendril is withered rapidly, fills with root with 1000 times of liquid of 50% chlorobromide isocyanuric acid or 600 times of liquid of 40% thiophanate-methyl sulphur suspends or 500 times of liquid of 70% mancozeb.The Chinese yam brown rot piece root of mainly causing harm, general results are seen often, the irregular moth patch of the shape that occurs on the piece potato rotting; depression slightly, sick piece is deformity often, the deliquescing of rot section; this disease must early be prevented, and uses 800 times of liquid irrigating root treatments of 3000 times of liquid of 80% S-Ethyl ethylthio sulfonate or 70% thiophanate methyl.
Adopt the method, Chinese yam continuous crop success rate reaches more than 96.8%, and output is substantially without impact.
