The application belongs to the technical field of vegetable cultivation, and particularly relates to a seed priming method for improving radish seedling emergence rate. The radish seeds are primed by using water extract of broccoli seeds, and are dried through variable-temperature drying, so that seed germination in the priming process is avoided, and indexes such as seedling emergence rate, seedling emergence time and seedling fresh weight are significantly improved, and the improvement effect is obviously better than that of water priming and polyethylene glycol priming. The problem of low radish seedling emergence rate is effectively solved.

The present application relates to a kind of film planting method for improving watermelon seedling resistance and its application.The film planting method includes that the seedling of 20~25 d seedling age is planted in the central groove of "M" type ridge, then film is covered on the ridge, and seedling growth is carried out.The method can significantly improve the salt alkali dry land watermelon seedling slow-recovery rate, survival rate and early growth potential, effectively improve the soil water content around root zone, reduce the surface soil salt concentration, optimize rhizosphere environment, enhance its drought tolerance and salt tolerance, and then improve its fruit setting rate and yield.The present application further carries out seed priming treatment to salt-tolerant watermelon varieties with brackish water, then uses the improved nutrient soil of saline-alkali soil to raise seedling, and is planted in combination with "M" type ridge film planting mode, constructs the complete watermelon seedling resistance cultivation system from variety selection-seed resistance priming-improved substrate seedling-raising-microenvironment regulation in field, and provides reliable scheme for efficient cultivation of saline-alkali drought resistance watermelon seedling.

The application belongs to the technical field of microorganisms, and particularly relates to a Botrytis cinerea IBc-248 and application of the Botrytis cinerea IBc-248 in preventing and treating plant Botrytis cinerea and / or promoting plant growth; the Botrytis cinerea IBc-248 has a preservation number of CCTCC M 2026254. The Botrytis cinerea IBc-248 disclosed in the application is not only non-pathogenic to tomato plants, but also can effectively prevent and treat Botrytis cinerea and can be colonized in the roots of tomatoes through seed priming. With the growth of the plants, the Botrytis cinerea IBc-248 can endophytically expand to stems and leaves, thereby providing continuous protection for the whole growth period of the tomatoes, and this characteristic significantly simplifies the application method and reduces the cost. In addition, the Botrytis cinerea IBc-248 also has the effect of promoting the development of plant root systems: the Botrytis cinerea IBc-248 can promote the growth of root systems in the initial stage of tomato seed germination, and can significantly increase the number of inter-root and total root length in the adult stage.
