This invention provides a method for transient transformation of oil palm zygote embryos based on Agrobacterium-mediated transformation, which employs the Agrobacterium-mediated approach and is based on the optimal Agrobacterium concentration (OD) for stable transformation of oil palm. 600 The optimal Agrobacterium infection time for zygotic embryos was determined by measuring the concentration of acetylsuccinone and co-culture time. The transient GUS expression staining rate was compared between zygotic embryos of different oil palm varieties and at different growth stages. The method described in this invention optimizes infection conditions based on stable transformation parameters, clarifies the optimal explant materials and treatment process, and effectively improves transient transformation efficiency and experimental repeatability. This study establishes for the first time an Agrobacterium-mediated transient transformation system for oil palm zygotic embryos and obtains zygotic embryos most suitable for transient transformation, achieving efficient transient expression of exogenous genes in oil palm zygotic embryos. This provides a rapid and low-cost technical means for studying oil palm gene function.

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.

This invention proposes a method for improving nutrient utilization efficiency in oil palm through synergistic reduction of fertilization and mechanical weeding, relating to the field of agricultural planting management technology. The method involves the formulation of nitrogen, phosphorus, and potassium fertilizers, with pure nitrogen applied at a rate of 120-156 kg / ha per year, phosphorus pentoxide at 15-20 kg / ha per year, and potassium oxide at 160-210 kg / ha per year. The fertilizers are applied twice, in April and October each year, within a 2-meter radius of the oil palm trees. Mechanical weeding is performed at the same frequency within the 2-meter radius of the oil palm trees and between rows, without the use of chemical herbicides. This invention improves nitrogen utilization efficiency by over 65% while maintaining the yield of fresh oil palm fruit, and increases the yield increase of phosphorus and potassium fertilizers by over 195% and 20% respectively, while significantly reducing nitrogen leaching loss from deep soil layers. It is suitable for mature oil palm plantations on mineral soils.
