The pest control method of traditional strawberry is mainly to adopt Agro-chemicals control, but the large multipair Strawberry Virus control efficiency of agricultural chemicals using except methyl bromide in cultivation is unsatisfactory, and the agricultural chemicals such as methyl bromide are the agricultural chemicals that will regularly stop using or limit use, and the use of a lot of agricultural chemicals does not meet the non-polluted cultivation of current requirement or the standard of organic farming yet.Thereby, in cultivation, conventionally adopt cultivation detoxic seedling carry out soilless culture, insect control, cut-out virus route of transmission or select the modes such as resistant variety to alleviate the harm of virus to strawberry.At present, the nontoxic seedling of strawberry is cultivated the 3 kinds of methods that mainly contain: heat cure method, anther culture and Shoot Tip Culture method, wherein Shoot Tip Culture method be obtain at present the nontoxic seedling of strawberry the most generally, effective method.At present, although virus-free seedling is cultivated technology comparative maturity, easily subinfection again, need to regularly replace seedling.
Research is found, a lot of physical factors, chemical factor and biological factor have strong effect to genetic material, and researcher extensively and has in depth studied the mutagenesis mechanism of these factors, such as Wang Weidong etc. have been discussed in detail in ion implantation process vacuum, temperature etc. for the impact of seeding ratio etc. in " vacuum and the temperature impact on wheat seedling growth in ion implantation process " literary composition.But for seedling, excessively strong stimulation tends to change its genetic material, relates to the research and development of complicated new varieties, and variation risk wherein and the environmental and ecological requirement growing to even greater heights at present inconsistent.
Herein in the face of being to provide a kind of relatively gentle, can significantly improve the cultivated strawberry method of strawberry seedling preventing disease and pest performance.
Summary of the invention
Object of the present invention is to provide a kind of cultivated strawberry method that improves strawberry seedling preventing disease and pest performance, and it mainly comprises the steps such as the choosing of seedling, the processing of seedling and the field planting of seedling;
The processing of wherein said seedling, mainly comprises the following steps:
One, pretreatment: by strawberry seedling successively with 75% alcohol-pickled sterilization 5-8s, 0.1%HgCl 2clean by sterile water wash after sterilization 1-2min, 0.5% clorox sterilization 0.5-1min;
Two, stifling processing: pretreated seedling is placed in to the saturated vapor environment of 40-42 ℃, passes into the mixture of Bromide methane and carbon dioxide simultaneously, fumigate processing, the time is 2-4min;
Three, application of vacuum; It is that 2-3kPa, temperature are 20 ℃ that the seedling that stifling processing is obtained is placed in pressure, implements application of vacuum, and the time is 10-15h.
As preferably, being chosen for of described seedling selected at bog moss: the culture matrix that vermiculite is 1:1 is cultivated the red Strawberry Seedlings of perfume (or spice) obtaining for 2 months.
As preferably, the field planting of described seedling is to carry out the canopy that is provided with fly net is indoor, the wide about 1m of furrow, and dark about 25cm, every furrow field planting a line, can arrange moth-killing device or carry out sulfur fumigation processing canopy is indoor if desired.
The invention has the advantages that: by the combination treatment method of stifling chemical treatment and physical vacuum processing, and in each processing procedure, optimized parameter is chosen, have excellent desinsection detoxification efficiency concurrently, and excellent growth result, rationally control injury and the risk processed, thereby obtained a kind of novel cultivated strawberry method.
Embodiment
Further describe content of the present invention below in conjunction with specific embodiment.
Embodiment 1:
The cultivation method of strawberry mainly comprises the steps such as the choosing of seedling, the processing of seedling and the field planting of seedling, and wherein the processing of seedling is carried out in the following manner:
One, pretreatment: choose bog moss: the culture matrix that vermiculite is 1:1 is cultivated the fragrant red Strawberry Seedlings of the stalwartness obtaining for 2 months as seedling under 15-20 ℃ of greenhouses, successively with clean by sterile water wash after 75% alcohol-pickled sterilization 6s, 0.1%HgCl2 sterilization 1min, 0.5% clorox sterilization 1min;
Two, stifling processing: pretreated seedling is placed in to the saturated vapor environment of 40 ℃, mixture to the concentration of Celfume that passes into volume ratio simultaneously and be 2:1 Celfume and carbonic acid gas is 10g/m 3, fumigate processing, the time is 2min;
