Abstract

The invention relates to a planting method of white paeony roots. The planting method comprises the steps of base fertilizer application, planting, management of a growing period, pest control and prevention and harvesting and processing. At the growing period, when the white paeony roots are 10-15cm high, branches which are 1-2.5cm far away from the upper part of the soil are cut to form wedged gaps, the sectional area of the gaps on one wider ends of the radial directions of the branches are 1 / 3 greater than the cross section area of the branches at the place, the gaps are larger in lower part and smaller in upper part, and the gaps are coated by a mixture of 2-5g of quick lime, 1-2g of urea and 3-6g of plant ash and are covered by cloths, and then 1500 times of compound sodium nitrophenolate solution is sprayed to the branches of the white paeony roots. The planting method of white paeony roots is simple and feasible, the yield of the white paeony roots can be improved by 32% by processing fertilizers in the growing process, and the content of 2-year old paeoniflorin of the white paeony roots can reach up to a medicinal standard, the age limit between the planting and harvesting for medicine can be greatly reduced, the economic benefit of the white paeony roots can be improved, and the paeoniflorin content in the white paeony roots can be improved by 15%.
