Salt tolerance hydroponic test method for sweet sorghum

Abstract

The invention provides a salt tolerance hydroponic test method for sweet sorghum. A sodium chloride aqueous solution is poured on a paper bed in a germination box, the germination box is placed in a bud bed bracket device, disinfected seeds are placed into the bud bed bracket device and cultured in an illumination incubator, filter paper is replaced every day, the bud bed bracket device is washed, the sodium chloride aqueous solution is poured for continuous culture to obtain sweet sorghum seedlings, the seedlings are planted from longitudinal notches of transplanting pipes, the roots of the seedlings are exposed out of the bottoms of the transplanting pipes, two seedlings are transplanted into each transplanting pipe, the bases of the seedlings are wound and fixed through absorbent cotton, the transplanting pipes penetrate out of foam floating plates from planting holes, the roots of the transplanting pipes are located on the bottom sides of the foam floating plates, the upper ends of the transplanting pipes are transversely removed along the transverse notches of the transplanting pipes, and the treated foam floating plates are placed into the sodium chloride aqueous solution, and a salt tolerance hydroponic test is carried out. Errors caused by non-uniform water supplementation in germination are avoided, the bud bed support device is used for dividing the space of the paper bed to place seeds, management and statistics are facilitated, the transplanting pipes are designed for efficient transplanting, and the seedlings are not damaged.

Description

Technical field [0001] The present invention belongs to the technical field of sweet sorghum germination chamber, in particular to a sweet sorghum salt water culture methods. Background technique [0002] Salt stress have a significant impact on crop growth and development, the performance of seed germination and crimes against salt stress by particularly severe during seedling growth. Sweet sorghum anti-salinity tolerance of strong, as a feed crop in southern Xinjiang region, have broad prospects for development, and therefore carry sweet sorghum sprout stage salt has identified certain research value for salt tolerant varieties of screening and gene mapping and significance. Salt identified currently available, the use of paper artificial bed using NaCl solution at shoots of salt stress on crop tolerance indices identified, but often in the daily management process quantitatively added salt stress treatment according to the case of the wet filter paper moisture, can not guarant...

AI Technical Summary

Problems solved by technology

At present, the existing salt tolerance identification mostly uses paper beds to artificially simulate salt stress with NaCl solution at the germination stage to identify crop salt tolerance indicators. Moisture, consistent salt concentration during
