Embodiment 1
[0023] A wheat hybridization method for improving seed setting rate, comprising the following steps:
[0024] 1) Sow the male parent and the female parent, and when the male parent and the female parent grow to the flower bud differentiation stage, spray the wheat growth-promoting agent on the male parent and the female parent;
[0025] 2) When the male parent and the female parent grow to the heading stage, when the female parent ear is completely drawn out, use a pin to peel off the flag leaf and cut off 1 / 3 of each spikelet, remove the stamen, and spray the pistil growth promoter, Get the cellophane bag and cover the female parent's ear after the treatment in the cellophane bag, and fix the test tube filled with water at 5-10 cm above the female parent's ear in the cellophane bag with iron wire, when the selected male parent hybridized with the female parent grows to During the flowering stage, intercept the male parent ear and put it into the fixed water test tube in the c...
Embodiment 2
[0032] The wheat hybridization method of this embodiment to improve the seed setting rate is different from the embodiment in that the wheat growth promoter is prepared from the following raw materials in percentage by weight: 0.1% amino acid chelated zinc, 0.1% amino acid chelated calcium, amino acid chelated Chelated boron 0.1%, superphosphate 0.2%, ammonium phytate 0.2%, nucleotide 0.3%, rice vinegar 1%, the balance is water;
[0033] The pistil growth-promoting agent is prepared from the following raw materials in percentage by weight: amino acid chelated boron 0.02%, amino acid chelated calcium 0.4%, bovine serum albumin 1%, mannitol 5%, pectinase 0.04%, Cellulase 0.1%, hemicellulase 0.1%, gibberellic acid 0.05%, lansoprazole 0.05%, sodium nitroprusside 0.1%, the balance is water;
[0034] The grouting regulator is prepared from the following raw materials in weight percent: gibberellin 0.05%, potassium dihydrogen phosphate 0.1%, humic acid 0.05%, amine fresh fat DA-6 0.5...
Embodiment 3
[0037] This embodiment improves the wheat hybridization method of the seed setting rate, and the difference from the embodiment is that the wheat growth-stimulating agent is prepared from the following raw materials in percentage by weight: amino acid chelated zinc 0.2%, amino acid chelated calcium 0.2%, amino acid Chelated boron 0.2%, superphosphate 0.5%, ammonium phytate 0.4%, nucleotide 0.5%, rice vinegar 2%, the balance is water;
[0038] The pistil growth-promoting agent is prepared from the following raw materials in percentage by weight: amino acid chelated boron 0.06%, amino acid chelated calcium 0.6%, bovine serum albumin 2%, mannitol 6%, pectinase 0.2%, Cellulase 0.3%, hemicellulase 0.3%, gibberellic acid 0.08%, lansoprazole 0.06%, sodium nitroprusside 0.2%, the balance is water;
[0039] The grouting stage regulator is prepared from the following raw materials in percentage by weight: gibberellin 0.08%, potassium dihydrogen phosphate 0.2%, humic acid 0.07%, amine fr...
