The application discloses a method for promoting oil palm callus proliferation and somatic embryo induction by using baicalin. The tender yellow leaf of oil palm is used as a tissue culture explant, and Y3 medium is used as a basic medium, and baicalin is added to promote the induction and proliferation of oil palm callus and somatic embryo generation. In the callus induction and proliferation stage, 0.5 mg / L of baicalin can replace part of the effect of 2,4-D or dicamba, reduce the dosage of 2,4-D or dicamba, reduce the risk of subsequent regeneration deformity, shorten the callus induction time by 20 days, and increase the callus proliferation rate by 48.19%; in the somatic embryo induction stage, 0.3 mg / L of baicalin can completely replace the plant hormone 6-BA, and the somatic embryo induction time is shortened by 31 days, and the somatic embryo induction rate is increased by 5%. Therefore, the addition of baicalin in the medium can improve the efficiency of oil palm callus proliferation and somatic embryo induction, shorten the induction time, and has a good popularization and application prospect in the field of oil palm tissue culture and rapid propagation.

The invention discloses all-solid waste concrete. The all-solid waste concrete is prepared by mixing the following components in parts by mass: 350-500 parts of a cementing material, 980-1140 parts of coarse aggregate, 890-960 parts of fine aggregate and 120-160 parts of water, the cementing material comprises slag, stainless steel slag, fly ash, desulfurized gypsum and an exciting agent; the coarse aggregate comprises ferrochrome slag; the fine aggregate comprises ferronickel slag. According to the all-solid waste concrete disclosed by the invention, a solid waste material rich in a CaO-SiO2-Al2O3 system is selected as a cementing material, the cementing material is self-decomposed under the action of water and reacts to generate C-S-H gel and ettringite, and the ettringite and the flocculated C-S-H gel are tightly interwoven to form a compact structure, so that the strength of the concrete can be remarkably improved at the early stage of hydration of the concrete; implementation verifies that the all-solid-waste concrete can meet the requirements of C40-grade concrete at most, all-solid-waste materials are 100% adopted, the problem of environmental pollution caused by solid waste stockpiling can be solved, and meanwhile regenerated products with high additional value are formed.

The invention discloses a method for promoting oil palm callus proliferation and somatic embryo induction by utilizing baicalin. Oil palm tender yellow leaves are used as tissue culture explants, a Y3 culture medium is used as a basic culture medium, and baicalin is added to promote oil palm callus induced proliferation and somatic embryogenesis. Wherein 0.5 mg / L of baicalin is added in the callus induction proliferation stage, the effect of part of 2, 4-D or dicamba can be replaced, the dosage of 2, 4-D or dicamba is reduced, the risk of subsequent regeneration malformation is reduced, the callus induction time is shortened by 20 days, and the callus proliferation rate is increased by 48.19%; 0.3 mg / L of baicalin is added in the somatic embryo induction stage, so that plant hormone 6-BA can be completely replaced, meanwhile, the somatic embryo induction time is shortened by 31 days, and the somatic embryo induction rate is increased by 5%. Therefore, by adding the baicalin into the culture medium, the callus proliferation and somatic embryo induction efficiency of the oil palm can be improved, the induction time is shortened, and the method has good popularization and application prospects in the field of tissue culture and rapid propagation of the oil palm.
