Cutting seedling-raising method capable of making oryza plants ward off diseases and detoxified rapidly

Abstract

The invention relates to a cutting seedling-raising method capable of making oryza plants ward off diseases and detoxified rapidly and belongs to the technical field of plant detoxification. The cutting seedling-raising method capable of making the oryza plants ward off diseases and detoxified rapidly comprises the steps of material taking form fields, disease warding-off, detoxification and sterilization treatment conducted on stems, stem cuttage preprocessing, stem cuttage and stem rejuvenation and cultivation. By utilizing a plant disease warding-off and detoxification technology, the pollution problem in the oryza stem cuttage process is solved effectively, the stems are higher in survival rate after cuttage, cutting seedlings grow vigorously and are good in growth vigor, and an effective means is provided for rejuvenation and rapid propagation of important hybridization materials and saving of wild rice high-quality germplasm resources. The method is simple, easy to operate and low in cost, the oryza plants surviving through cuttage are good in growth vigor, and diseases and insect pests do not occur basically. In addition, a cutting seedling-raising period is short, next transplantation can be performed in 1-2 months generally and is not affected by seasons and other environmental factors, and large-scale popularization and application can be achieved. The method can be also applied to saving and rapid propagation of certain rare oryza varieties.

Description

technical field [0001] The invention relates to a method for growing seedlings by cuttings capable of quickly detoxifying oryza plants, belonging to the technical field of plant detoxification. Background technique [0002] Oryza genus, Poaceae, about 25 species, distributed in tropical regions, divided into cultivated rice and wild rice. Wild rice is a general term for all wild species other than cultivated rice (O. sativa L.) and African cultivated rice (O. glaberrima Steud.). [0003] Long-term artificial selection has made the genetic background of cultivated rice in my country very narrow. The narrow genetic background, coupled with the growth of global population in recent years, the reduction of cultivated land area, and global climate change, make rice production vulnerable to pests and diseases and environmental pollution. Lead to a serious decline in rice yield and quality. Wild rice has long-term survival in the wild and has strong stress resistance. It is a natu...

Problems solved by technology

However, the conventional cutting method is prone to large-scale fungal contamination in the early stage of cultivation, and re-contamination of endophytic bacteria sometimes occurs during the cultivation process, resulting in material loss

[0005] The present invention provides a cutting seedling raising method that can quickly remove diseases and viruses from Oryza plants. After literature search, there is no public report on the same technology as the present invention.
