The application discloses a cadmium tolerance related protein IbCSase of sweet potato and an encoding gene and application thereof, and belongs to the technical field of biotechnology, and particularly relates to the cadmium tolerance related protein IbCSase of sweet potato and the encoding gene and application thereof. The protein IbCSase is any one of the following: A1) a protein with an amino acid sequence as shown in SEQ ID No. 1; A2) a protein with more than 80% identity with the protein shown in A1) and the same function, which is obtained by substitution, deletion and / or addition of amino acid residues of the protein of A1); and A3) a fusion protein obtained by connecting a protein tag to the N terminal or / and C terminal of A1) or A2). By introducing the IbCSase encoding gene into wild type sweet potato, the tolerance of the plant to heavy metal cadmium can be improved, the IbCSase encoding gene can be applied to sweet potato breeding, and has wide application space and market prospect in the agricultural field.

The application provides a integrated groove frame for shallow direction cultivation of Dioscorea alata L., and belongs to the technical field of yam planting. The device comprises a rectangular groove, a U-shaped groove and a vine traction pipe. The U-shaped groove is arranged in the rectangular groove and has a strip shape for guiding the directional growth of Dioscorea alata L. The vine traction pipe is arranged at the top of the rectangular groove and has an arc shape arranged at the top end and the end of the rectangular groove. The vine traction pipe is used for directional traction of the vines of Dioscorea alata L. The depth of the rectangular groove ranges from 25 cm to 30 cm. The groove frame has a depth ranging from 25 cm to 30 cm, which reduces the dependence of planting on the thickness of the soil layer. The vine traction pipe forms a continuous vine climbing path. After the vines of Dioscorea alata L. grow, the vines are guided to climb on the vine traction pipe, so that the vine leaves are uniformly distributed and mutual shading is avoided. The efficiency of vine photosynthesis is optimized, and the vines are prevented from lodging. When harvesting, the U-shaped groove is directly taken out, large-area soil turning is avoided, the damage to tubers and the destruction of soil structure are reduced, and the integrity of harvesting is improved.
