Method for planting magnesium-rich eucommia ulmoides

The invention discloses a method for planting magnesium-rich eucommia ulmoides. The method includes the steps that S1, seeds are soaked with fresh water for one day and then placed into a 100 micro-g/ml carbendazim solution to be soaked for 20 min; S2, a planting area is selected and plowed and raked two times to three times, magnesium-containing base fertilizers and soil are evenly mixed, deep plowing is carried out by 25 cm, root bottoms are leveled, and ridges with the width of 0.8 m to 1 m and the height of 20 cm to 25 cm are made; S3, the seeds are arranged in the ridges with the applied magnesium-containing base fertilizers at 5-cm intervals and covered with plant-ash-mixing soil with the thickness of 1.5 cm to 2 cm, and straw is flatly laid on the ridges along furrows to carry out heat preservation; S4, after emerging, saplings in the good growing state are transplanted, holes with the width of 80 cm to 100 cm and the depth of 30 cm are dug according to 2-m line spacing, magnesium-containing base fertilizers are applied at the bottoms of the holes and evenly mixed with soil, then the saplings are arranged in the holes, root systems are stretched, soil is added layer by layer and treaded compactly, and the saplings are watered with sufficient root fixing water. The content of magnesium in the eucommia ulmoides planted with the method is more than three times that of magnesium in common eucommia ulmoides, the content of glucoside, the content of alkaloid, the content of pectin, the content of organic acid, the content of ketose, the content of vitamins and the content of lignans are also greatly increased, and the medical effect of the eucommia ulmoides is improved.
