Platform for identifying saline-alkaline resistance of rice in controllable saline-alkali gradient environment and use method thereof

Abstract

The invention discloses a platform for identifying saline-alkaline resistance of rice in a controllable saline-alkali gradient environment and a using method thereof, belonging to the field of agricultural science. The platform comprises a greenhouse, culture pits are dug in the greenhouse, and culture containers are placed in the pits, which are respectively filled with non-saline soil, light saline-alkali soil, moderate saline-alkali soil and severe saline-alkali soil, so as to carry out rice seedling raising, transplanting and field management, and investigate rice yield and constituent factors after harvest, so as to carry out saline-alkaline resistance identification of different varieties. The invention can accurately simulate the growth environment of rice under different saline-alkali gradients, and provide a scientific and repeatable experimental platform for salt-tolerance and alkaline identification of rice varieties.
